Answer:
All of them are true.
Step-by-step explanation:
x^2 y - z / x^2 is true. x^2, when divided by itself, cancels itself out, so the equation that is left is y - z.
For the second one, a/c + b/c is true because when you add a + b = it will change; it will be added together. the remaining c will stay the same, as it is the denominator/the same, so you keep it as it is.
For the final one, you distribute ^2 to (a+b), so they become a^2 + b^2.
This means that all of the statements are true.

Answer:
47.85 ft³
Step-by-step explanation:
$6 million will be $6/$5 million = 1.2 million bills of the $5 denomination.
The volume of that is ...
(1.2×10⁶ bills)×((2.61 in)(6.14 in)(0.0043 in)/bill)/(1728 in³/ft³)
= 1.2×2.61×6.14×4.3/1.728 ft³ ≈ 47.85 ft³
___
The units analysis is ...
where the volume per bill is the product of the given dimensions, and the conversion to cubic feet is ...
in³ × (ft³/in³) = ft³
where the number of cubic feet per cubic inch is 1/1728.
Answer:
45 newspapers can be delivered in 3 hours.
Step-by-step explanation:
Given that,
Kevin delivers 30 newspapers in 2 hours.
We need to find how many newspapers can be delivered in 3 hours.
