The blueprint of a pool has a scale of 2 inches equals 7 feet. the scale drawing is shown below. the length is 20 and the width is 10 part a what are the actual dimensions of the pool? enter your answers in the boxes. blueprint: 10 in. actual: ft blueprint: 20 in. actual: ft part b how much would it cost to buy a cover for the pool that costs $0.30 per square foot? enter your answer in the box. $

Divide the scaled dimensions by 2, then multiply that by 7:

Length: 20 / 2 = 10. 10*7 =  70 feet.

Width: 10 / 2 = 5. 5 * 7 = 35 feet.

A) The pool is 70 feet long by 35 feet wide.

B) Area is length x width

Area = 70 * 35 = 2,450 square feet.

Cover cost 0.30 per square foot.

Total cost = 2,450 x 0.30 = $735

Part A. 70 feet, 35 feet

Part B. $735

Step-by-step explanation:

The blue print of a pool has a scale of 2 inches equals to 7 feet.

The length in blueprint is 20 inches and the width is 10 inches.

Part A.

∵ 2 inches = 7 feet

∵ 1 inch = 7/2 = 3.5 feet

20 inches = 3.5 × 20 = 70 feet

10 inches = 3.5 × 10 = 35 feet

The actual dimensions of the pool  Blueprint 10 in. Actual 35 feet, Blueprint: 20 in Actual : 70 feet.

Part B.

To buy a cover for the pool that costs $0.30 per square foot.

Area = Length × width

Area = 70 × 35 = 2,450 feet²

cost per square foot = $0.30

for 2,450 square foot = 2,450 × 0.30 = $735.00

It costs $735 to buy a cover for the pool.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
