there are 250 n each has a mass of 5.2x10 to the negative 3 power kilograms.What is the total mass in kilograms in decimal form
Answer:
the total mass of the 250 objects is 1.3 kilograms.
Step-by-step explanation:
To find the total mass of the 250 objects, we need to multiply the mass of each object by the number of objects:
Total mass = mass per object x number of objects
The mass per object is given as 5.2x10^-3 kg, and the number of objects is 250. So, we can calculate the total mass as follows:
Total mass = 5.2x10^-3 kg x 250
Total mass = 1.3 kg
Jacque is using a soup can for a school project and wants to paint it. If the can is 11 cm tall and has a diameter of 9 cm, at least how many square centimeters of paint is needed? Approximate using π = 3.14.
374.45 cm2
139.50 cm2
699.44 cm2
438.03 cm2
Answer:
The surface area of the soup can is given by the formula:
SA = 2πr² + 2πrh
where r is the radius of the circular ends of the can, h is the height of the can, and π is approximately 3.14.
The radius of the can is half of the diameter, so r = 4.5 cm.
Therefore, the surface area of the can is:
SA = 2π(4.5)² + 2π(4.5)(11)
SA = 2π(20.25) + 2π(49.5)
SA = 40.5π + 99π
SA = 139.5π
Approximating π as 3.14, we get:
SA ≈ 139.5 × 3.14
SA ≈ 438.03 cm²
Therefore, at least 438.03 square centimeters of paint are needed to cover the can.
So, the answer is 438.03 cm2.

x = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = 1, b = 3, and c = -10.
Substituting these values, we get:
x = (-3 ± sqrt(3^2 - 4(1)(-10))) / 2(1)
x = (-3 ± sqrt(49)) / 2
x = (-3 ± 7) / 2
x1 = 2
x2 = -5

How many quarts of pure antifreeze must be added to 5 quarts of a 10 % antifreeze solution to obtain a 30 % antifreeze solution?
According to the solving this algebra approximately 1.43 quarts of pure antifreeze to the initial 5 quarts of 10% antifreeze solution to obtain a 30% antifreeze solution.
what is algebra?
Mathematical operations are applied to abstract symbols rather than concrete numbers in the field of algebra, which also includes other formal manipulations. The area of mathematics known as geometry is concerned with the qualities of the space that objects are in as well as the shape of the objects themselves.
According to the given information:
Let Q be the number of quarts of pure antifreeze to be added.
Let 0.10(5) be the amount of antifreeze in the initial 5 quarts of the 10% antifreeze solution, which is 0.5 quarts.
To obtain a 30% antifreeze solution, the amount of antifreeze in the final solution should be 0.3(5+Q) quarts.
Since we are only adding pure antifreeze, the amount of antifreeze in the final solution will be the sum of the antifreeze in the initial solution and the antifreeze we add:
0.5 + Q = 0.3(5+Q)
Now we can solve for Q:
0.5 + Q = 1.5 + 0.3Q
0.7Q = 1
Q = 1/0.7
Q ≈ 1.43
Therefore, we need to add approximately 1.43 quarts of pure antifreeze to the initial 5 quarts of 10% antifreeze solution to obtain a 30% antifreeze solution.

A store had 869 swimsuits that were marked to sell at $45.95. Each suit was marked down $17.90. Find the reduced price using the formula M=S-N, where M is the mark down, S is the original selling price, and N is the reduced price.
The reduced price of the swimsuit is $28.05 being obtained by using the mark down value and selling price of the product.
Explain Pricing?
A price technique that allows for discussion between the supplier and the buyer is flexible pricing. The supplier does not provide a fixed price while using this tactic. They decide on a price range in advance so that they can haggle with the customer. A vendor will have a minimum number they can take and a maximum number they may charge when using flexible pricing.
Using the formula M=S-N, where M is the mark down, S is the original selling price, and N is the reduced price, we can find the reduced price of each swimsuit as follows:
M = $17.90
S = $45.95
N = S - M
N = $45.95 - $17.90
N = $28.05
Therefore, the reduced price of each swimsuit is $28.05.

Solve for the tangent line of cos(x) at x= pi/4. Use the tangent line to estimate the value of cos(48).
The estimated value of cos(48) by using tangent line is found to be
0.99989.
Explain about the tangent line ?A straight line which thus touches a function only once is called a tangent line.
The first step is to calculate y when x=π/4. We will receive that target coordinate point as a result.
The required coordinate point is ( π/ 4, √(2) / 2)
The derivative of such function y is then discovered.
y ' = -sin(x)
Input the derivative with the value of x. This corresponds to the tangent line's slope.
y' = -sin(π/4)
y' = - √(2) / 2
The slope plus coordinate point are now entered into the gradient intercept form of the formula to obtain b.
y = mx + b
√(2) / 2 = (-√(2) / 2)(π / 4) + b
√(2) / 2 = (-π√(2) / 8) + b
(√(2) / 2) + (π√(2) / 8) = b
[4√(2) + π√(2)] / 8 = b
[(4 + π)√(2)] / 8 = b
The tangent line comes out to be:
y = (-√(2) / 2)x + [(4 + π)√(2) / 8]
Now , for cos(48).
48° = π/180 * 48 radians
48° = 3.14/180 * 48 radians
48° = 0.01744*48 radians
48° = 0.83712 radians
So, cos(48) = cos( 0.83712 )
Using scientific calculator:
cos(48) = cos( 0.83712 ) = 0.99989
Thus, the estimated value of cos(48) by using tangent line is found to be
0.99989.

One angle in an isosceles triangle has a measure of 20
. Find the measure of all other angles in the triangle. List all possible values for these angles. Do not enter the degree sign, just numbers.
Answer:
the possible answers are 80 and 140
Step-by-step explanation:
since one angle has a measure of 20 in isosceles triangle let this be vertex angle and other two as base angles then
in isosceles triangle base angles must be equal to each other so
x+x+20 = 180
2x+20 = 180
2x = 160
x=80
so the base angles are equal to 80
now if you suppose 20 as base angle then other base angle should also be 20 since it is an isosceles triangle and the vertex angle can be calculated as
20+20 + x = 180
x = 140

Alia has 36 1/4 inches shares of silver chain to make some braces if she needs 7 1/4 inches of the chain to make one bracelet how many bracelets can Alia
make
Answer:
To find the number of bracelets Alia can make, we need to divide the total length of the silver chain she has by the length of each bracelet.
Total length of silver chain = 36 1/4 inches
Length of each bracelet = 7 1/4 inches
To divide fractions, we need to invert the second fraction and multiply:
(36 1/4) ÷ (7 1/4) = (145/4) ÷ (29/4) = (145/4) x (4/29) = 5
Therefore, Alia can make 5 bracelets with the given amount of silver chain.
Answer:
5 bracelets
Step-by-step explanation:
Given Information:
Amount of chain needed for 1 bracelet: 7 1/4 inchesTotal chain length: 36 1/4 inchesClearly, the number of bracelets possible (say x) multiplied by the amount of chain required for 1 bracelet will result in the total chain length (36 1/4).
⇒ 7 1/4 × x = 36 1/4Now, we can divide 7 1/4 on both sides to find value of x (total bracelets).
⇒ (7 1/4 × x)/(7 1/4) = (36 1/4)/(7 1/4)⇒ x = (36 1/4)/(7 1/4) = 5Therefore, Alia can make 5 bracelets.

What is equation?A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13. 2x - 5 and 13 are expressions in this case. These two expressions are joined together by the sign "=".
Let's use the following variables:
CD = the number of CD singles sold
DL = the number of music downloads sold
From the problem, we know the following:
CD + DL = total number of singles sold
CD = 456
The profit from selling CD singles is 35p = £0.35 per CD single
The profit from selling music downloads is 17p = £0.17 per music download
The total profit is £246.64
Using the information above, we can set up two equations based on the profits earned from selling CD singles and music downloads:
0.35 * CD = profit from CD sales
0.17 * DL = profit from download sales
And we know that the sum of these two profits equals the total profit:
0.35 * CD + 0.17 * DL = 246.64
Substituting CD = 456, we get:
0.35 * 456 + 0.17 * DL = 246.64
Simplifying this equation, we get:
159.6 + 0.17 * DL = 246.64
0.17 * DL = 87.04
DL = 512

Question: You open a bank with a simple interest of 1.95% and your principal / p have been laying there for 30 whole years. After 30 years, you see that there is $800 in your brand account. What was the interest and what was the principal?
The Formula is I=P*R*T
interest, principal, rate, and time
Answer: To solve this problem, we can use the formula for simple interest:
I = P * r * t
where I is the interest earned, P is the principal, r is the interest rate as a decimal, and t is the time in years.
We are given that the interest rate is 1.95% = 0.0195, the time is 30 years, and the final amount in the account is $800. Let P be the principal we are trying to find.
First, we can use the formula to find the total interest earned over the 30-year period:
I = P * r * t
I = P * 0.0195 * 30
I = 0.585P
Next, we can use the fact that the final amount in the account is the sum of the principal and the interest:
800 = P + 0.585P
800 = 1.585P
P = 504.71
Therefore, the principal was $504.71 and the interest earned over the 30-year period was:
I = 0.585P
I = 0.585 * 504.71
I = 294.29
So the interest earned was $294.29.
