Answer:
3^7
Step-by-step explanation:
3^2 * 3^5
a^b * a^c, since the bases are the same, we can add the exponents
a^ ( b+c)
3^(2+5)
3^7
The volume of a cube is length x width x depth. In a cube all would be equal therefore.
<span>x^3= 64 </span>
<span>x =4 </span>
<span>The area in square feet of one side would then be length x width </span>
<span>There are 6 sides so the surface area of the cube would be </span>
<span>(4)(4)(6) = 96 square feet</span>
Answer:
Y = 63
Step-by-step explanation:
I think if x and y are proportional when y is 90 and x is 10 then that would mean that x multiplied by 9 would equal y so:
7 x 9 = 63
7 * 2.9
(7 * 2) + (7 * 0.9) = 20.3 <==
Answer:

e) 66.66%
f) 33.33%
g) 10%
h) 75%
i) 90%
j) 80%
k) 40%
I can't see all the options for part A so you will have to match them yourself. Also, know that any number from 5-9 rounds up and 1-4 rounds down.
