Answer:

7 inches

Step-by-step explanation:

I cant see the illustration, but I will assume it is a rectangle. The formula for the perimeter of a rectangle is P=2w+2l

let P represent the perimeter of the window in inches

let w represent the width of the window in inches

let l represent the length of the widow in inches

(L is l whereas one is 1)

So we know w=5 and P=24

This lets us have the equation 24= 2 x 5 + 2l

24=10 + 2l

14=2l

7=l

7 inches because if 5 is on both sides you add them and get 10. then you subtract 24-10 and get 14 and for 2 side lengths you divide 14 by 2 and 7.

One week, Kerry travels 125 miles and uses 5 gallons of gasoline. The next week, she travels 175 miles and uses 7 gallons of gas

SpyIntel [72]

The question is incomplete, the complete question is here:

One week , Kerry travels 125 miles and uses 5 gallons of gas. next week she travels 175 miles and uses 7 gallons of gas . what best describes the function that can be used to represent m, the number of miles traveled, and g, the number of gallons used

The best function represents the relation between m and g is m = 25 g

Step-by-step explanation:

The given is:

One week, Kerry travels 125 miles and uses 5 gallons of gasoline
The next week, she travels 175 miles and uses 7 gallons of gasoline
m represents the number of miles traveled by g gallons

We need to write a function that can be used to represent m and g

∵ Kerry travels 125 miles and uses 5 gallons of gasoline in

one week

∴ The rate = 125 ÷ 5 = 25 miles per gallon

∵ She travels 175 miles and uses 7 gallons of gasoline in

next week

∴ The rate = 175 ÷ 7 = 25 miles per hour

- That means the rate is constant

∴ The relation between the number of miles and the number of

gallons used is linear

- The linear relation is y = k x, where k is the constant of relation

∵ m is the number of miles

∵ g is the number of gallons

∵ 25 is the constant rate

∴ m = 25 g

The best function represents the relation between m and g is m = 25 g

On an airplane there are two seats on the left side in each row and three seats on the right side there are 90 seats on the righ

Anuta_ua [19.1K]

The correct answer is 60 seats on the left side, but you might also want to know how I got that answer . . .

Let's say, n = number of rows

Since we know the airplane has an equal number of rows on the right side as it does on the left side, then we can mathematically show that:

number of sears on the right side = 3n = 90 seats
number of sears on the left side = 2n = ? seats

3n = 90

n = number of rows = 90/3 = 30 rows

Thus:

2n = 2(30) = 60 seats on the left side

as for how many seats all together, just add . . 90 + 60 = 150 seats total

A dog is on a 20-foot leash in the backyard. Approximately how much area does the dog have to move around in the yard?

iragen [17]

With a 20 ft leash, the dog can move in the circle. Now, knowing that he can move around in a circle, we just need to use the circle formula. A = 3.14(r) squared.
Since you use 3.14 for pi; A = 3.14(20) squared --> A = 1256

Answer = 1256
