Answer:

27. 110.5

28. 33%

29. 20%

Step-by-step explanation:

27. subtract 15% of 130 from 130

so 15% of 130 is 19.5

130 - 19.5 = 110.5

28. find markup first by subtracting the prices = 55

percent markup = 55/165 × 100

= 33%

29. subtract the two = 29 discounted

29/145 ×100 = 20% discount

sorry if the explanations aren't detailed. lemme know if u still don't understand.

A group of students organized a car wash to raise money for a local charity. The students charged $8.00 for each car they washed
3241004551 [841]

Answer:

$320

Step-by-step explanation:

First, we can find how many cars they washed.

At 8 hours, they washed 32 cars, and since you still have two hours worth of cars to find, you can divide 16 by 2, and you get 8.

So in total, they washed 40 cars.

Now, you can multiply 40 by $8.00, and you get $320.

PLEASE HELP! I WILL REWARD BRAINLY! I WILL CHOOSE BRAINLISTS!

To get the area of a rectangle, multiply the side lengths.
Our side lengths of this rectangle is 1/2 and 3/4, so let's multiply them.

\dfrac{1}{2} *  \dfrac{3}{4} =  \dfrac{3}{8}

Thus, the area of this rectangle is 3/8 ft². I hope this helps! :)

There is three fourths of a box of cereal remaining. You eat 2/5 of the remaining cereal. What fraction of the box do you eat
likoan [24]
You would eat 3/10 of the box because 3/4 times 2/5 is 3/10. Whenever you see the word "of" it means multiplication.
