6.5 because you instantly take $9.50 away from $55. After you get that answer, you will have 45.5. Then divide 45.5 by 7 which will give you 6 and a half hours.

A swimming pool is circular with a 40-ft diameter. The depth is constant along east-westlines and increases linearly from 2 ft a

AnnZ [28]

Answer:

volume will be equal to 5,655 ft³

Step-by-step explanation:

diameter of swimming pool = 40 ft

depth increases from east-west lines is from 2 ft to 7 ft

so the average depth of the swimming pool can be calculated by

$D_{avg} = \frac{2+7}{2}$

hence average depth comes out to be 4.5 m

volume of water in the pool will be equal to the volume of the pool

volume = $\pi\times r^2 \times d_{avg}$

= $\pi\times 20^2 \times 4.5$

= 5,654.86 ft³

volume will be equal to 5,655 ft³ approximately

On a map, the scale shown is 1 inch : 3 miles. If an island is 0.5 square inches on the map, what is the actual area of the isla

gtnhenbr [62]

Answer:

4.5

Step-by-step explanation:

First we need to turn the ratio of 1 : 3 into a fraction

1:3 = 1/3

Next we need to square that fraction

1 x 1 = 1

3 x 3 = 9

Then we turn those numbers into a fraction

1/9

We turn the .5 into a fraction

.5/x

And cross multiply both fraction by each other

1/9 x .5/x

1 x X = X

9 x .5 = 4.5

4.5 = X
