Pls And thanks
Answer:
12.8
Step-by-step explanation:
13 feet is the length of the other side of the room.
What is the area of the rectangle ?The formula for area is equal to the product of length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.
Given here, 2inches =5feet thus 1 inch is equivalent to 5/2 feet and let the length of the other side is x
now area of the room is 24.96 inches²
Thus in feet the area is 24.96×(5/2)²=156 feet²
Also 12 × x = 156
x = 13 feet
Hence the length of the other side is equal to 13 feet

It means: Perimeter × the sum of the lengths of all the sides.
Hope it helps!<3
Answer:
The surface of the polygon is the total space or area that is limited by the borders of the polygon.
Step-by-step explanation:
This area is the amount of space limited by the borderlines and occupied by a polygon. By definition, the sides of the polygon are the same in size. The area of any polygon can be defined by dividing the polygon into triangles.
Kyle saves 8% of his income for a new car. This year his salary was $2,000 less than in the previous year, and he saved $3,000. What was his salary in the previous year?
Answer:
let this previous income be x
then 8% of (x-2000) = 3000
or, 8/100*(x-2000) = 3000
or, x - 2000 = 3000/0.08
or, x -2000 = 37500
x = 37500+2000 =39500 is his previous year salary

Find the domain and range of the function represented by the graph.
Brian deposited $1,075 in an account that pays 2.35% simple interest for 3 ½ years. (9 pts.) How much total interest did the account earn? ______________ What is the ending balance in the account? ______________ How much interest did the account earn in the first year? _______________
Answer:
The total interest the account earned was $88.41.
The ending balance in the account is $1,163.41.
The account earned $25.26 in interests in the first year.
Step-by-step explanation:
The simple interest is one that does not accumulate to the initial capital, that is to say that the capital does not accumulate over the years.
Therefore, if Brian deposited $ 1,075 in an account with an interest of 2.35% per year for 3 and a half years, to obtain the total interest generated by the account, the following calculation must be performed:
(1,075 x 2.35 / 100) x 3.5 = X
25.2625 x 3.5 = X
88.41 = X
Thus, the interest generated during the first year was $ 25.26, while the accumulated interest during 3 and a half years was $ 88.41. In turn, since 88.41 + 1,075 equals 1,163.41, that is the resulting amount after the end of the investment.
A restaurant is offering 2 specials: 10 burritos for $12, or 6 burritos for $7.50. Noah needs 60 burritos for his party. Should he buy 6 orders of the 10-burrito special or 10 orders of the 6-burrito special?
Answer:
6 orders of the 10 burrito special
Step-by-step explanation:
10 burritos for $12
60 burritos for $72.
6 burritos for $7.50
10 burritos for $75
So the 10 burritos for $12 is better.

Mia Chloe and tony entered their
Answer:
Option A
Step-by-step explanation:
We know that Mia's frog only jumped [tex]\frac{4}{5}[/tex] the distance of Chloe's frog - which means that Mia's frog must be behind Chloe's frog. Therefore, Mia's frog must also not be in first place.
We also know that Tony's frog jumped [tex]1\frac{1}{4}[/tex] the distance of Chloe's frog - meaning that Tony's frog jumped further than Chloe's frog, since it is above 1. So, Tony's frog is ahead of Chloe's frog. Therefore, Chloe's frog cannot be in first place either.
Let's look at the clues gathered so far:
Tony's frog is ahead of Chloe's frog. Mia's frog is behind Chloe's frog. Mia's frog is not in first place.Using logic, the only option that meets these requirements would be option A. Tony would be ahead of Chloe, Mia would be behind Chloe, and neither of the girls' frogs would be in first place. You could also use the process of elimination to get rid of the other answers.
Find the area of a square with side length of 4x.
Answer:
16x²
Step-by-step explanation:
since all sides of a square are equal, we just multiply 4x by 4x. this gives us 16x².
The area of square with side length 4x is 16x.
What is Square?A square is a two-dimensional closed shape with 4 equal sides and 4 vertices.
Given,
The side length of a square is 4x
We need to find the area of square.
As we know that area of square = 4a.
Where a is the length of side of a square.
In a square all the four sides will have same length.
a=4x
Area of square=4(4x)
=16x
Hence the area of square with side length 4x is 16x.

. The graph below shows the amount of money spent on a homeowners insurance bill and the period of time passed. Based on the information in the graph, how much will the Jones family spend on homeowners insurance after 9 months?
Answer:
$450
Step-by-step explanation:
First, find an equation that represents the proportional relationship between number of months (x) and amount spent (y).
A proportional equation can be represented in the form, y = kx, where,
k = constant of proportionality = y/x
Using a point on the line, (1, 50),
k = 50/1 = 50.
Substitute k = 50 into y = kx
The equation would be:
y = 50x
After 9 months (x), they would pay the following:
Substitute x = 9 into y = 50x
Thus:
y = 50(9)
y = 450

Correct principal is $1200.
Answer:
R = 6.736%
Step-by-step explanation:
Formula for simple interest is;
Interest = PRT/100
We are given;
Principal; P = $1200
Time; T = 6 years
Interest; I = $485
Rate; R =?
From, Interest = PRT/100, we have;
485 = 1200 × R × 6/100
Making R the subject gives;
R = 485 × 100/(6 × 1200)
R = 6.736%

ducational Television In a random sample of people, said that they watched educational television. Find the confidence interval of the true proportion of people who watched educational television. Round the answers to at least three decimal places.
Complete Question
Educational Television In a random sample of 200 people, 159 said that they watched educational television. Find the 90% confidence interval of the true proportion of people who watched educational television. Round the answers to at least three decimal places.
Answer:
The 90% confidence interval is [tex]0.748 < p < 0.842[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 200
The number of people that watched the educational television is [tex]k = 159[/tex]
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{159}{200}[/tex]
=> [tex]\^ p = 0.795[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 1.645 * \sqrt{\frac{0.795 (1- 0.795)}{200} } [/tex]
=> [tex]E = 0.04696 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex]0.795 -0.04696 < p < 0.795 + 0.04696[/tex]
=> [tex]0.748 < p < 0.842[/tex]
