80 cubes
Step-by-step explanation:
volume of one small cube = 1 /2 × 1 / 2 × 1 / 2

1 / 8 × x = 10
x = 10 × 8
x = 80 cubes
Answer:
$295.01
Step-by-step explanation:
Using the compounding continuously formula, we are looking for A. We have that P = 190; r = .11 (always use the decimal form of the rate!); and t = 4. Filling in we have:

Simplifying that multiplication:
.
On your calculator, raise e to the .44 power to get
A = 190(1.552707219) and
A = $295.01
It's 18 because all u have to do it divide
Answer:
15x + 9
Step-by-step explanation:
9(3x + 8) – 3(4x + 21)
Multiply
27x + 72 - 12x - 63
Combined like terms
27x - 12x = 15x 72 - 63 = 9
15x + 9
