$122.57 • 4 + $555.28 = $1,045.56
$136.71 • 4 + $585.34 = $1,132.18
$1,132.18 - $1,045.56 = $86.62
Answer:
15 minutes i think
Step-by-step explanation:
45÷6=7.5
meaning 7.5 minutes per girl

Answer:

Step-by-step explanation:
we know that
There are about 125,000 Brine shrimp in 1 pound
1 pound contains 96 teaspoons
so
There are about 125,000 Brine shrimp in 96 teaspoons
Using proportion
Find out how many teaspoons of brine shrimp represent 3000 Brine shrimp
Let
x -----> the number of teaspoons

Simplify

Convert to mixed number

It's either a (the first one) or b (the second one), but if I had to choose I would choose b. If I'm wrong I'm so sorry I spent 10 minutes looking at this.
64 = 4³
-216 = (-6)³
.008 = 0.2³ . . . . . . 1000 = 10³, 8 = 2³. This is 8/1000, so the cube of 2/10
1/64 = (1/4)³ . . . . . . the inverse of the first number
4 17/27 = 125/27 = (5/3)³

You can see that it would be helpful to have memorized the cubes of small integers.
