Ok we need to solve for x.

First add 5 to both sides.
\frac{5}{8}x = 10
Divide \frac{5}{8} from both sides
x =  16
(If you don't know how to divide fractions then comment or DM me)

The answer is x = 16

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

Answer:

C

Step-by-step explanation:

We know it's direct variation using the direct variation equation.

y=kx

Where k is the constant.

Since 7 times x is the y values, k=7

Now we can substitute 7 into k of the direct variation equation.

y=7x

If a snowball melts so that its surface area decreases at a rate of 3 cm2/min, find the rate (in cm/min) at which the diameter d
grin007 [14]

Answer:

The diameter decreases at a rate of 0.053 cm/min.

Step-by-step explanation:

Surface area of an snowball

The surface area of an snowball has the following equation:

S_{a} = \pi d^2

In which d is the diameter.

Implicit differentiation:

To solve this question, we differentiate the equation for the surface area implictly, in function of t. So

\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}

Surface area decreases at a rate of 3 cm2/min

This means that \frac{dS_{a}}{dt} = -3

Tind the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm.

This is \frac{dd}{dt} when d = 9. So

\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}

-3 = 2*9\pi\frac{dd}{dt}

\frac{dd}{dt} = -\frac{3}{18\pi}

\frac{dd}{dt} = -0.053

The diameter decreases at a rate of 0.053 cm/min.
