Answer:

A

Step-by-step explanation:

√(x^5) = x^(5/2) = (x^2)√x

√9x = (√9)(√x) = (3)√x

which means: ((x^2)√x) + ((3)√x)

since both have a √x, you can factor it out. for example...if you look at A, if you apply the distributive property you can see it expands back out. hmu if you need a different. explanation

A model car is 8 inches long and 5.2
Sphinxa [80]
Use proportions here - 8/5.2 = 96/width of actual car. using cross multiplication, 5.2*96 = 8x. this gives you 499.2 = 8x. divide both sides by eight to get x=62.4. the width of the actual car is 62.4 inches.

Quincy was stuck inside during an afternoon rainstorm. He spent 20 minutes reading books, 18 minutes eating lunch, 12 minutes wa
SSSSS [86.1K]

Answer:

The answer is B. He spent 3 minutes eating lunch for every 10 minutes.

Step-by-step explanation:

He spent stuck inside during the brainstorm for:

20+18+12+10= 60 minutes in total.

And now we want to know what he did for every 10 minutes he spent in the rainstorm. To do that we need to divide what he did for every 10 minutes by the total of minutes that he was stuck:

\frac{10}{60} =\frac{1}{6}

And now we can multiply the time of the activities by 1/6 to get the time he did each activity every 10 minutes.

Reading:

20*\frac{1}{6} = 3.33 minutes reading for every 10 minutes.

Eating:

18*\frac{1}{6} = 3 minutes eating for every 10 minutes.

Watching TV:

12*\frac{1}{6} = 2 minutes watching TV for every 10 minutes.

Drawing:

10*\frac{1}{6} = 1.67 minutes drawing for every 10 minutes.

Therefore he spent 3 minutes eating lunch for every 10 minutes.
