Answer:
144π or 452.4
Step-by-step explanation:
Volume of a Sphere Formula: V = 4/3πr³
Step 1: Plug in 6 for <em>r</em>
V = 4/3π(6)³
V = 288π
Step 2: Divide by 2
V = 288π/2
V = 144π
The answer to the question is A: 0.96 centimeters
of 1.6 is 0.64
If you subtract 0.64 from 1.6 you get 0.96, 
of 1.6
Answer:
<h3><u>8 Km.</u></h3>
Explanation:
- I'm going to turn the fractions into decimals
2 ½: 2.5
3 ⅕: 3.2
- Formula for the area of a parallelogram: A = b(h)
Base: 3.2
Height: 2.5
3.2 · 2.5 = 8
<h3><u>The area of the parallelogram is 8 Km.</u></h3>
Answer:
$32
Step-by-step explanation:
To find the commission, multiply the rate by the sales:
commission = 5% × $640 = $32
He made $32 in commission.

<em>Additional comment</em>
Many calculators and all spreadsheets can work with percentages directly. If yours can't, or if you can't do this arithmetic mentally, you can use the equivalent decimal or fraction for 5%.
5% = 5/100 = 0.05 = 1/20
Then 5% × $640 = $640/20 = $64/2 = $32.
It is direct variation if x/y is a constant.
x/y = 2 / -6.6 = -1/3.3
y/x = -9.9/3 = -3.3
y/x = -6.6/ 2 = -3.3
y/x = -13.2/ 3 = -3.3
y/x = -16.2/ 3 = -3.24
So its not exactly direct variation as the last values is slightly different from the first 3.
