Answer:

The height of triangle EFG is 9 units

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the area of a square ABCD

The area of a square is equal to

A=b^2

where

b is the length side of the square

we have

b=AB=6\ units

substitute

A=6^2=36\ units^2

step 2

Find the height of triangle EFG

The area of triangle EFG is equal to

A=\frac{1}{2}(b)(h)

where

b is the base of triangle

h is the height of triangle

we have

b=EG=8\ units

A=36\ units^2 ---> area of triangle EFG is the same that the area of square ABCD

substitute the given values in the formula

36=\frac{1}{2}(8)(h)

solve for h

36=4h\\h=9\ units

therefore

The height of triangle EFG is 9 units

Norma and Albert both clean pools. Each charges a flat fee to clean a pool. Norma cleans 12 pools in 8 hours and earns $270. Alb
Novosadov [1.4K]

Answer:

1.5 per hour : 1.2 per hour

Step-by-step explanation:

The computation of the ratio is shown below:

For norma, the one pool would be

= 12  pools ÷ 8 hours

= 1.5 per hour

And for albert, the one pool would be

= 9 pools ÷ 7.5 hours

= 1.2 per hour

So the ratio between them is

1.5 per hour : 1.2 per hour
