Answer:
$(4/3)X
Step-by-step explanation:
Working 12 hours, Samia gets paid for the first 8 hours ...
8 · ($X) = $8X
For the remaining 4 hours, she is paid ...
4 · ($2X) = $8X
Then for 12 hours, she is paid a total of ...
$8X +$8X = $16X
Her average hourly pay is then ...
total pay / total hours = $16X/12 = $(4/3)X . . . average hourly pay
If you would like to know the total value of the liquid in the container, you can calculate it using the following steps:
A cone:
a radius (r) ... 1 in.
a diameter ... 2 in.
a height (h) ... 9 in.
<span>π ... 3.14
</span>
Cone volume formula:
V = 1/3 * π * r^2 * h
V = 1/3 * 3.14 * 1^2 * 9 = 1/3 * 3.14 * 1 * 9
V = 9.42 cubic inches
$2 ... 1 cubic inch
$x = ? ... 9.42 cubic inches
_______________________
2 * 9.42 = 1 * x
x = 2 * 9.42
x = $18.84
The correct result would be $18.84.

Answer:
5x ^ 3 - 6x ^ 4
Expression 2:
-5x3 + 7x4 + 4x4 - 8x3
x4 (7 + 4) + x3 (-5-8)
11x4 - 13x3
Answer:
11x ^ 4 - 13x ^ 3
Expression 3:
-2x4 - 10x3 + 4x4 - 2x3
x4 (-2 + 4) + x3 (-10-2)
2x4 - 12x3
Answer:
2x ^ 4 - 12x ^ 3
Expression 4:
15x3 - 15x4 + 13x4 - x3
