What is the answer???
aev [14]

Answer:

The answer is C.

Step-by-step explanation:

As you can see, It won't be a square because the bottom is 4 units long and the triangle is an estimated 3 units tall, so you can cross those two answers out. Next, you can look at the first answer. What is obvious, the triangle is definitely not double a rectangle what has the same basic measurements as the triangle. Answer C is the only one that is logical.

A theater can hold 140 giants or 210 elves. If 90 giants are already inside, how many elves can also be admitted?
Temka [501]
75 elves.

I created a fraction to help solve for the number of elves. I did so by:

90/x=140/210 

I solved for x which would equal 135. This is the equivalent number of elves in the theater. You would subtract this number from 210 which would equal 75.

OR 

You can figure out how many elves equal 1 giant. In this case, you would divide 210 by 140 which equals 1.5 giants. Since there are 90 giants, you multiply 1.5 giants to find out an equivalent for elves which would equal 135. Same as before, subtract this from 210, resulting in 75.

What is 28% of 63%? Round your answer to the nearest tenth
Zina [86]

Answer: 17%

Step-by-step explanation:

1. First divide the percentages by 100 to turn the percentages into a decimal (28/100) x (63/100) = 0.1764

2. Then turn that decimal into a percentage again.

0.1764 x 100 = 17.64 but if you’re rounding to the nearest tenth without any decimals it’ll just be 17%
