Answer:

30 hours.

Step-by-step explanation:

Richard can build 15 snowballs in 1 hour

But 2 snowballs melt every 15 minutes

In 1 hour, the number of snowballs that will have melted is:

$\frac{60}{15}$ × 2 = 8

The number of snowballs that will have remained = 15 - 8 = 7

So 7 snowballs will have remained in 1 hour

For 210 snowballs to have remained, it will take:

$\frac{210}{7}$ × 1 = 30 hours.

Find the area. 7 in. 5 in. 12 in.

vitfil [10]

Answer and Step-by-step explanation:

The area formula for a trapezoid is as follows:

A = $\frac{a + b}{2}h$

Where:

A = Area

a = top side length

b = bottom side length

h = height

Plug in the values given to you into the equation and solve.

A = $\frac{7 +12}{2}(5)$

A = $\frac{19}{2}(5)$

A = $\frac{95}{2}$

A = 47.5 $in.^2$ is the answer.
