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.

Find the Mean:
Find the median
Find the Mode:
Answer:
Mean: 46 Median: 45 Mode: 45
Step-by-step explanation:
Mean: 41+45+39+56+48+45+42+34+47+62+35+58 = 552 then, 552/12 = 46
Median: Put numbers in order from least to greatest and cross one out on each side until you get to the middle number. 45 and 45 were the last two numbers to be crossed out, the middle of those would simply be 45!
Mode: 45 appears twice while the rest of the numbers only appeared once.
I hope this helped, good luck! :)

Assume a mats price from the start is "X" USD. Write an expression for what the mat would cost after being reduced by P % (unknown amount of percentage)
Answer:
Step-by-step explanation:
[tex]cost \ price = X\\Deduction = P \%\\Deduction \ Price = P \% of X = \frac{P}{100} \times X = \frac{XP}{100} \\\\Cost \ price \ after \ deduction = X -\frac{XP}{100}[/tex]
OR SIMPLIFY FURTHER
[tex]X - \frac{XP}{100} = X( 1 - \frac{P}{100} )[/tex]
