A fund drive announces that it has raised $4,376, which is 20% of it's goal. How much more must be raised?

1 answer:

5 0

Since 20% of a goal is 1/5 of the whole thing, then we must multiply 4376 by 4, since 1/5 + 4/5 = 5/5.
4376 * 4 = 17504
So the fund drive must raise $17504 more.

HELP! Given a pyramid l = w = 9.0 mm and V = 324.0 cubic mm , find h in mm

harina [27]

Answer:

The answer to your question is height = 12 mm

Step-by-step explanation:

Data

l = w = 9 mm

V = 324 mm³

h = ?

Formula

V = $\frac{Ab x h}{3}$

Solve for h

3V = Ab h

3V / Ab = h or h = 3V / Ab

Find the area of the base

Ab = l x w

= 9 x 9

= 81 mm²

Substitution

h = $\frac{3(324)}{81}$

Simplification

h = $\frac{972}{81}$

Result

h = 12 mm
