An item is regularly priced at $51. Amanda bought it on sale for 85% off the regular price. How much did Amanda pay?

Step-by-step explanation:

True or false: any nonzero integers, the product and the quotient have the same sign. Why?

Answers

False. This is because no matter what the number is, the properties of multiplication and division stay the same. So, if one odd and even number multiply/divide, then the answer will be negative. But, if two numbers of the same sign (both either negative or positive) are divided/multiplied, they will both be positive. Therefore, the result is not always the same sign as the starting integers

Denise has 1/2cup of vegetable oil that she will use in making several batches of cookies. Each batch requires 1/8 cup of vegetable oil. evaluate the expression below to find the number of batches of cookies Denise will make

Answers

First, you need to set the denominators equal.
1/2=4/8
Then divide.
(4/8)/(1/8)=(4)/(1)=4.
Notice that the denominators cancel each other out. You then have whole numbers that divide easily.
The answer is that Denise can make 4 batches of cookies on 1/2 cup of vegetable oil.

Hi! Since the cake is split into eight slices, this is a simple equation.

1/2 of the cake is four slices. 8/4=2 Shontavia may have a stomach ache!

1/8 also means one slice.

So, 1/8+4/8+2/8=7/8. Only one slice is left! The correct answer is F.
