Snow is falling at a rate of 2.5 inches per hour.At this rate, how long will it take 8 inches of snow to fall?

jeyben [28]

Answer:

It will take 3.2 hours for 8 inches of snow to fall.

Step-by-step explanation:

You can solve this be going "backwards".

You have 2.5 inches of snow falling per hour for x hours until you get 8 inches of snow, which can be represented like this:

2.5x=8 From here you being to solve by isolating x on one side of the equation. You would divide both sides by 2.5 to do this

2.5x=8

/2.5 /2.5

8 divided by 2.5 is 3.2 and you then get

x=3.2

It takes 3.2 hours for 8 inches of snow to fall

Suppose that c varies jointly with d and the square of g, and c = 30 when d = 15 and g = 2.

maksim [4K]

Answer:

$d = \dfrac{3}{16}$

Step-by-step explanation:

c varies jointly with d and the square of g

$c\propto dg^2$

$c=kdg^2$

where, k is constant of proportionality.

Put the given value c = 30 when d = 15 and g = 2 and find out k

$30=k\cdot 15\cdot 2^2$

$k=\dfrac{1}{2}$

$c=\dfrac{1}{2}kg^2$

If c = 6 and g = 8 then d = ?

$6=\dfrac{1}{2}\cdot d\cdot 8^2$

$d=\dfrac{6\cdot 2}{8^2}$

$d=\dfrac{3}{16}$

Hence, The value of d is $\dfrac{3}{16}$

A chicken casserole recipe serves 12

Musya8 [376]

Answer:

4.5 cups of spinach

Step-by-step explanation:

we know that

The recipe serves 12 people and calls for 3 cups of spinach

using proportion

Find out how many cups of spinach should you use, to serve 18 people

$\frac{12}{3}\ \frac{people}{cups} =\frac{18}{x}\ \frac{people}{cups}\\\\x=18(3)/12\\\\x=4.5\ cups$
