Find the surface area of the prism. 13cm 16cm 5cm 12cm
the surface area of the prism is 706 cm². To find the surface area of a prism, we need to add up the areas of all its faces.
A prism is a three-dimensional shape that has two parallel and congruent bases that are connected by rectangular sides. Therefore, the surface area of a prism consists of two congruent base areas and the area of all rectangular sides.
In this case, we have a rectangular prism with a length of 13 cm, a width of 16 cm, and a height of 5 cm. To find the surface area, we can start by calculating the area of the two rectangular bases. The area of a rectangle is found by multiplying its length by its width, so the area of each base is 13 cm x 16 cm = 208 cm².
Next, we need to calculate the area of all four rectangular sides. Since there are four sides, we need to multiply the perimeter of the base (the sum of the lengths of all four sides) by the height of the prism. The perimeter of the base is 2(13 cm + 16 cm) = 58 cm, so the total area of all four rectangular sides is 58 cm x 5 cm = 290 cm².
Finally, we can find the total surface area of the prism by adding the areas of the two bases and the area of all four sides. Therefore, the surface area of the prism is:
Surface area = 2(base area) + (area of all sides)
Surface area = 2(208 cm²) + 290 cm²
Surface area = 706 cm²
Therefore, the surface area of the prism is 706 cm². It is important to understand how to find the surface area of different shapes since it is a common concept in mathematics and is often used in real-life applications, such as calculating the amount of paint needed to cover a surface or the amount of wrapping paper needed to wrap a gift box.

a student has to take 9 more courses before she can graduate. if none of the courses are prerequisites to others, how many groups of five courses can she select for the next semester?
The number of groups of five courses the student can select for the next semester is 126.
In order to answer this question, we must first determine how many courses the student has already taken. If the student has already taken 11 courses, then the total number of courses she needs to take is 9.
We can use the formula for combinations, nCr, to calculate the number of groups of five courses that she can select for the next semester. The formula is nCr=n!/(r!(n-r)!). In this case, n is the total number of courses (9) and r is the number of courses in each group (5).
Therefore, the number of groups of five courses the student can select for the next semester is 9C5, or 9!/[5!(9-5)!], which equals 126. This means the student can select 126 different groups of five courses for the next semester.

8 Cans of mandarin oranges are needed to serve a part of 200 people if each person is to receive a 3-ounce serving and each can weights 5 pounds 10 oz (9 ounces of that as liquid which you will discard).
Given that each can of mandarin oranges weighs 5 pounds 10 oz (9 ounces of that as liquid which you will discard).We are to find out how many cans of mandarin oranges are needed to serve a part of 200 people if each person is to receive a 3-ounce serving.
Convert 3 ounces into pounds and ounces
3 ounces = 3/16 pound (1 pound = 16 ounces)
Amount of mandarin oranges required by one person = 3/16 pound
Amount of mandarin oranges required by 200 people = 200 * (3/16) pound
Amount of mandarin oranges required by 200 people = 37.5 pound
Convert the amount of mandarin oranges required into cans
Weight of one can of mandarin oranges = 5 pounds 10 oz = (5*16 + 10) ounce = 90 ounce
Weight of mandarin oranges only in one can = 90 ounce - 9 ounce = 81 ounce (9 ounce is liquid which you will discard)
Number of cans required = (total weight required) / (weight of one can)Number of cans required = (37.5 * 16) / 81 Number of cans required = 7.4 cans

The perimeter of isosceles triangle PRQ is 24.65 units.
The lengths of its three sides and add them up. We can use the distance formula to find the length of each side.
Distance formula: The distance d between two points (x1, y1) and (x2, y2) is given by:
d = [tex]sqrt((x2 - x1)^2 + (y2 - y1)^2)[/tex]
Using this formula, we can find the lengths of the sides PR, RQ, and PQ.
PR = [tex]sqrt((-1 - (-7))^2 + (4 - (-1))^2) = sqrt(36 + 25) = sqrt(61)[/tex]
RQ =[tex]sqrt((3 - (-1))^2 + (-1 - 4)^2) = sqrt(16 + 25) = sqrt(41)[/tex]
PQ = [tex]sqrt((3 - (-7))^2 + (-1 - (-1))^2) = sqrt(100) = 10[/tex]
Therefore, the perimeter of triangle PRQ is:
PR + RQ + PQ = [tex]sqrt(61) + sqrt(41) + 10 ≈ 24.65[/tex] (rounded to two decimal places)

Answer:
To find the number of people who can have a full serving of trail mix from 50 ounces, we need to divide the total amount of trail mix by the amount of trail mix per serving.
50 ounces of trail mix / 12 ounces per serving = 4.1667 servings
Since we can't have a fraction of a serving, we need to round down to the nearest whole number.
So, Victor can make 4 servings of trail mix from 50 ounces. Therefore, 4 people can have a full serving of trail mix.
an certain brand of upright freezer is available in three different rated capacities: 16 ft^3 , 18ft^3 what is the variance of the price paid by the next customer
As per the given probability, the values of
(a) E (X) is 17.4 ft³, E (X²) is 323.2 ft⁶, and V (X) is 2.16 ft⁶.
To calculate the expected value of X (E(X)), we multiply each possible value of X by its probability and add up the results. Using the probability mass function given, we have:
E(X) = (16)(0.3) + (18)(0.5) + (20)(0.2) = 17.4
This means that on average, the rated capacity of a freezer sold at this store is 17.4 ft³.
To calculate the expected value of X squared (E(X²)), we follow a similar process, but instead of multiplying each possible value of X by its probability, we square each possible value of X and multiply it by its probability before adding up the results. Using the probability mass function given, we have:
E(X²) = (16²)(0.3) + (18²)(0.5) + (20²)(0.2) = 323.2
This means that on average, the square of the rated capacity of a freezer sold at this store is 323.2 ft⁶.
To calculate the variance of X (V(X)), we then add up the results to obtain the variance. Using the probability mass function given, we have:
V(X) = (16 - 17.4)²(0.3) + (18 - 17.4)²(0.5) + (20 - 17.4)²(0.2) = 2.16
This means that the variance of the rated capacity of a freezer sold at this store is 2.16 ft⁶. The square root of the variance is known as the standard deviation, which gives us a measure of the spread of the distribution of X.

Step-by-step explanation:
You want the area of the shaded portion of the unit square shown.
CircumcenterPoints B, C, E are shown as equidistant from point F, so will lie on a circle centered at F. The center of that circle is at the point of coincidence of the perpendicular bisectors of BE, BC, and CE.
Without loss of generality, we can let line EF lie on the x-axis such that E is at the origin. Chord EB of the circle has a rise of 1/2 for a run of 1, so a slope of 1/2. Its midpoint is (1, 1/2)/2 = (1/2, 1/4). The perpendicular line through this point will have slope -2, so its equation can be written ...
y -1/4 = -2(x -1/2)
y = -2x +5/4
Then the x-intercept (point F) will have coordinates (0, 5/8):
0 = -2x +5/4 . . . . . y=0 on the x-axis
2x = 5/4
x = 5/8
TrapezoidTrapezoid EFCD will have upper base 5/8, lower base 1, and height 1/2. Its area is ...
A = 1/2(b1 +b2)h

The value of mean should be adjusted to 12 + 2.576σ so that 99% of the cans will contain 12 oz or more.
The process mean can be adjusted through calibration. The mean is a measure of central tendency in a dataset that represents the average value of a group of data. The population standard deviation is denoted by σ. The formula for the population mean is as follows: μ = (Σ xi) / n, where xi represents the data values and n represents the total number of data values.
Here we can use the formula of confidence interval as,μ±z σ/√n, Where μ is the mean, z is the z-score, σ is the standard deviation is the sample size. Given,The required confidence level is 99%. So,α = 1-0.99α = 0.01. We can find z from the z-score table at α/2 = 0.005 as, z = 2.576.
Now, we need to find out the value of μ when the mean will be 12 ounces so that 99% of cans will contain 12 ounces or more. So,μ ± z σ/√n = 12. We know that, P(X > 12) = 0.99. The formula for standardization is, Z = (X - μ) / σHere, X = 12, σ is given and we need to find the value of μ.z = (X - μ) / σ2.576 = (12 - μ) / σμ - 12 = 2.576 × σμ = 12 + 2.576 × σ.

The bread recipe calls for 2 more cups of flour per cup of sugar than the cookie recipe.
========================================================
Explanation:
I'll use this shorthand
s = sugarf = flourSomething like "2 cups of sugar" will shorten to "2s".
The cookies need 3s for every 6f.
Therefore we get this ratio
3s : 6f
And we can divide both sides by 3 to end up with
s : 2f
Meaning "each cup of sugar needs 2 cups of flour".
--------------------
Meanwhile, the bread recipe calls for 2s for every 8f.
2s : 8f
2s/2 : 8f/2 .... divide both sides by 2
s : 4f
When making bread, each cup of sugar needs 4 cups of flour. In other words, the amount of flour is quadruple that of the sugar.
--------------------
Recap
Cookies have the ratio of s : 2fBread has the ratio of s : 4fThese ratios are reduced so that we have "s" on the left side without any numbers attached to it. In other words, we have 1s.
We can see that the bread needs 2 more cups of flour compared to the cookies (since 4f - 2f = 2f). It's important that we reduce those ratios so that we're talking about the same amount of sugar for each food item.
This is why choice B is the final answer.
--------------------
An example:
Each food item will use 1 cup of sugar.
The cookies need twice the amount of flour, so the cookies require 2 cups of flour (because of the ratio s:2f mentioned earlier).
The bread needs quadruple the amount of flour compared to sugar. Meaning the bread needs 4 cups of flour (because of the ratio s:4f).
Then subtract to get
(4 cups flour for bread) - (2 cups flour for cookies) = 2 cups flour

The number of shoes sold varies inversely with the price two thousand shoes can be sold at the price of $250
The phrase "the number of shoes sold changes inversely with price" suggests that as the price of the shoes rises, so does the number of shoes sold, and vice versa.
We know that 2000 shoes can be sold for $250 in this circumstance. Using the inverse variation formula, we can write: k/Price = number of shoes sold where k is a proportionality constant. We may use the following information to calculate the value of k: 2000 = k/250 When we multiply both sides by 250, we get: k = 500000 In this case, the equation for the inverse variation is: Price/number of shoes sold = 500000 We may use this equation to compute the number of shoes sold at various prices. For instance, if the price is If the price is $300, the number of shoes sold is: The number of shoes sold is 500000/300, which is 1666.67.

The function represents exponential decay with a rate of 4.98% per time unit.
Describe Exponential Function?An exponential function is a mathematical function of the form f(x) = a^x, where a is a positive constant (called the base) and x is a variable that can take on any real value. The exponent x determines how quickly the function grows or decays.
If a is greater than 1, the function represents exponential growth, since each increment of x leads to a proportionally greater increase in the function value. If a is between 0 and 1, the function represents exponential decay, since each increment of x leads to a proportionally smaller decrease in the function value.
For example, the function f(x) = 2^x represents exponential growth, since each time x increases by 1, the value of the function doubles. On the other hand, the function g(x) = (1/2)^x represents exponential decay, since each time x increases by 1, the value of the function is halved.
The given function is y = 990(0.95)ˣ.
We can determine whether the change represents growth or decay by looking at the base of the exponential term, which is 0.95. Since this value is between 0 and 1, we know that the function represents decay.
To determine the percentage rate of decrease, we can compare the value of the function at x=0 (the initial value) with the value of the function at x=1 (one time unit later).
When x=0, we have:
y = 990(0.95)⁰ = 990
When x=1, we have:
y = 990(0.95)¹ = 940.5
Therefore, the percentage rate of decrease is:
[(990-940.5)/990] x 100% = 4.98%
So the function represents exponential decay with a rate of 4.98% per time unit.

Thus, it is clear from the above-mentioned definitions that it is possible to have a c2 strictly convex function on a compact domain that is not also strongly convex.

a coffee distributor needs to mix a(n) gualtemala antigua coffee blend that normally sells for $8.50 per pound with a gazebo coffee blend that normally sells for $13.10 per pound to create 10 pounds of a coffee that can sell for $12.64 per pound. how many pounds of each kind of coffee should they mix?
The system of equations, helps to determine the quantity of each kind of coffee for mixture. The 9 pounds of Guatemala antigua coffee blend and one pound of gazebo coffee blend should be mix.
We have a coffee distributor needs to mix a(n) Guatemala antigua coffee blend. Let us assume, x = pounds of the Guatemala antigua coffee blend
y = pounds of the gazebo coffee blend
The new mixture is 10 pounds, so x + y = 10
And normally sells value of Guatemala antigua coffee blend per pound = $8.50
so, sells for x pounds of the Guatemala antigua coffee blend = $8.50x
Normally sells value of gazebo coffee blend per pound = $13.10y
Total sells = $12.64 × 10
8.50x + 13.10y = 12.64 × 10
We have the following system of equations:
x + y = 10 --(1)
8.50x + 13.10y = 126.4 --(2)
We have to solve the system of equations for determining value x and y. Using the Elimination method, from equation (1), x = 10 - y, put in equation (2), 8.50x + 13.10y = 126.4
=> 8.50 ( 10 - y ) + 13.10y = 126.4
=> 85 - 8.5y + 13.10y = 126.4
=> 4.6 y = 41.4
=> y = 41.4/4.6 = 9
from equation (1), x = 10 - 9 = 1
Hence, required value is 9 pounds and 1 pounds.

what is the missing value in the following arithmetic sequence? n 1 2 3 4 5 an 2 3.8 5.6 9.2 7.1 7.2 7.4 7.5
The missing value in the arithmetic sequence is 11.
What is Arithmetic Sequence?
An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.
To find the missing value in the arithmetic sequence, we need to first determine the common difference between consecutive terms.
To do this, we can subtract any two consecutive terms, such as the second and first terms:
3.8 - 2 = 1.8
This tells us that the common difference is 1.8.
Now, we can use this common difference to find the missing value, which is the sixth term in the sequence. We can use the formula for the nth term of an arithmetic sequence:
a_n = a_1 + (n - 1)d
where a_n is the nth term, a_1 is the first term, n is the position of the term we want to find, and d is the common difference.
Using this formula with a_1 = 2, d = 1.8, and n = 6, we get:
a_6 = 2 + (6 - 1)1.8
a_6 = 2 + 5(1.8)
a_6 = 2 + 9
a_6 = 11
Therefore, the missing value in the arithmetic sequence is 11.

in the given system of equations, p is a constant.the system has no solution. what is the value of p
When the given system of equations does not have a solution, it implies that there is no common point for both the straight lines to intersect. It means that both the straight lines are parallel to each other.
Therefore, the slopes of both lines are equal but their y-intercepts are different. Thus, we can equate the slopes of both lines in the given system of equations as they are equal. Then, we can form an equation to calculate the value of p.Let the given system of equations be:y =[tex]px + 4......(1)y = px + 6......[/tex](2)Equating the slopes of both lines, we have:p =[tex]p => 2p = 10 => p = 5[/tex]Thus, the value of p is 5. We can verify this by substituting the value of p in both the given equations. Therefore, the given system of equations can be written as:y = 5x + 4......(1)y = 5x + 6......([tex]5x + 4......(1)y = 5x + 6......([/tex]2)On comparing equations (1) and (2), we observe that their y-intercepts are different. The equation (1) has y-intercept 4 and equation (2) has y-intercept 6.
Hence, there is no common point for both the lines to intersect. Therefore, the system of equations has no solution.
