Answer:
0.512a³ cubic units
Step-by-step explanation:
Given a cube of length, a, then when decreased by 20%, what's left is actually 80% of the original. So, for this case, we have a cube with a length of 80%(a) = 0.80a.
Now, to compute for the volume of a cube, we multiply the length three times to itself. Or, in other words, raise the length to the third power. That means the volume of the new cube is (0.8a)³ = 0.512a³ cubic units.
Answer:
(8n/10)
8 × 5 = 40
40 ÷ 10 = <em><u>4</u></em>
Answer: 100,000 pounds
multiply the mass value by 2000
50×2,000=100,000
Answer:
12¾
Step-by-step explanation:
x - ¾ = 12
x = 12 + ¾
c = 12¾ or 12.75
1/2 of an hour is = 30
288 / 4.30=67
The answer is 67 miles per hour.
