Mr. D'Agostino decided he wanted to build a pool in his backyard this summer. He sketched a drawing that had a scale of 1 in. =
Travka [436]

Answer:

46080 ft²

Step-by-step explanation:

Given :

Scale :

1 in = 4 feets

Recall :

I foot =. 12 inches

Length of drawing = 4 feets

Length of drawing in inches = 4 * 12 = 48 inches

Width of drawing = 5 feets

Width of drawing in inches = 5 * 12 = 60 inches

Actual length of pool = 48 * 4 = 192 feets

Actual width of pool = 60 * 4 = 240 feets

The actual area of the pool :

Length * width

192 feets * 240 feets = 46080 ft²

Someone PLSSS HELPPPP !!!!
AnnZ [28]

Answer:

p^3  / q^12

Step-by-step explanation:

p^6 q^4

------------------

p^3 q^16

We know a^b / a^c = a^(b-c)

First with variable p

p^6 /  p ^3 = p^(6-3) = p^3

Then with variable q

q^4 / q^16 = q^(4-16) = q^-12  and a^-b = 1/ a^b = 1 /q^12

p^3 * 1/ q^12

p^3  / q^12

gladu [14]

Answer:

2167 meters squared

First find the area of the square ice skating rink: 47^2 = 2209.

Then, find the area of the triangle without ice by using 1/2bh: (12/2)(7)=42.

Simply subtract the triangle's area from the squares for the final answer of 2167 meters squared.
