Answer:

486\ toy\ boxes

Step-by-step explanation:

we know that

1\ ft=12\ in

step 1

Convert the dimensions of the boxes to feet

4\ in=4/12=(1/3)\ ft

step 2

Find the volume of the toy boxes

V=b^{3}

V=(1/3)^{3}=(1/27)\ ft^{3}

step 3

Find the volume of the crate

V=LWH

V=(3)(3)(2)=18\ ft^{3}

step 4

Divide the volume of the crate by the volume of the toy boxes to find the number of toy boxes

\frac{18}{(1/27)}= 486\ toy\ boxes

Which expression is equivalent to 4^-5 • 3^-5 ?
valkas [14]

The expression equivalent to 4^-5 • 3^-5  is 12^-5

<h3>What are equivalent expressions?</h3>

Equivalent expressions are simply known as expressions with the same solution but different arrangement.

Given the index expressions;

4^-5 • 3^-5

Using the exponent rule, the two values are have different bases but the same exponent and thus, we multiply the bases and leave the exponents the same way.

This can be written as;

4(3) ^ -5

expand the bracket

12^-5

Thus, the expression equivalent to 4^-5 • 3^-5  is 12^-5

Answer:

Your second answer, otherwise know as 1 in. : 4ft. is the answer.

Step-by-step explanation:

The new map is 3 times bigger than the old map, therefore your given scale for the first map will shrink by 3 to compensate for the new map being bigger. Divide 12ft by 3 and you get 4 ft., so your answer is 1in. : 4ft.

A waitress worked 5 hours at the pizzeria and earned $59.25. How much would the waitress expect to earn in 8 hours?
Trava [24]

Answer: 94.80

Step-by-step explanation:

First, let's divide the salary she made from 5 hours of work by 5 in order to see how much she makes in a single hour.

\frac{59.25}{5} = 11.85  per hour

Multiply this by 8 to find her amount made in 8 hours.

11.85 x 8 = 94.80
