I have a roof that measures 175 ft by 45 ft. During the hurricane 11 inches of rain fell.
Nikolay [14]

Answer:

  4.1 billion

Step-by-step explanation:

1 ft = 30.48 cm

1 in = 2.54 cm

The volume of rain that fell on the roof is given by ...

  V = LWH

  V = (175 ft × 30.48 cm/ft)(45 ft × 30.48 cm/ft)(11 in × 2.54 cm/in)

  = 175×45×11×30.48²×2.54 cm³ = 204,412,236.336 cm³

At 20 drops per cm³, this will be ...

  20×204,412,236.336 ≈ 4,088,244,727 . . . . raindrops

About 4.1 billion raindrops fell on your roof.

M+5n=p for m <br> Solving for a variable
Verdich [7]

Answer:

M=p-5n

Step-by-step explanation:

Here we are given that M+5n=p

We are asked to solve this equation for M. In order to do that we will follow these steps.

Subtracting 5n from both sides we get

M+5n-5n=p-5n

M=p-5n

Hence , now we have our M as dependent variable,  whose value depends on the values of p and n. One or both  of them can be independent variable/.
