Answer:

21,800

Step-by-step explanation:

I'm assuming you meant 2.18 x 10^4

Since the exponent is positive, you will move the decimal point 4 spaces to the right.

brilliants [131]

This problem basically already gives you X, you just have to simplify.

If the altitude is √7, find the volume. 36√7 cu. units 18√7 cu. units 12√7 cu. units

rosijanka [135]

Answer:

$Volume = 12\sqrt{7}$ cubic units

Step-by-step explanation:

Volume of the square pyramid is given as ⅓*area of base*height of pyramid.

Where,

Area of base = 6*6 = 36

Height of pyramid = altitude = $\sqrt{7}$ units

Plug the values into the formula to find volume.

$Volume = \frac{1}{3}*36*\sqrt{7}$

$Volume = 12*\sqrt{7}$

$Volume = 12\sqrt{7}$ cubic units

15 is 30% of what number?

777dan777 [17]

15 is 30% of 50

Change the percentage to a decimal by dividing it over 100:
$\frac{30}{100} = 0.3$

Divide 15 over 0.3:
$\frac{15}{0.3} = 50$
