Answer:

A. 64

Step-by-step explanation:

The shoes are 80 dollars.  We get a 20% discount

Discount = 80*20%

                = 80*.20

                  =16

The sales price = original price less the discount

                          = 80 -16

                           = 64

Add. Your answer should be a polynomial in standard form. ( − 8 y 2 − 9 y ) + ( 8 y 3 + 9 y 2 − 2 y ) =
aliya0001 [1]
(−8* y^2−9*y)+(8*y^3+9*y^2−2*y) 
first, remove extraneous parentheses (or distribute if negative)
=−8* y^2−9*y+8*y^3+9*y^2−2*y  
then group terms in decreasing degree of y (variable)
=+8*y^3 −8* y^2+9*y^2  −9*y−2*y
simply expression by adding/subtracting similar terms
=+8*y^3 +y^2  −11*y
to give the final answer.

23. Two coins are tossed. Alan gets a point if the coins match and Sondra gets a point if they do not match.
Keith_Richards [23]

Answer:

C. They have the  same chance of winning.

Step-by-step explanation:

Probability (2 tails) = 1/2 * 1/2 = 1/4

Probability( 2 heads = 1/2 * 1/2 = 1/4.

Therefore the Probability  they match = 1/4 + 1/4 = 1/2.

The probability of  they don't match = 1 - 1/2 = 1/2 because all probabilities add up to 1. There are only 4 possible results and their probabilities must add up to 1.

Mr. Ramsey just finished bathing his kids, and now he is draining the tub. The tub contains 32 gallons of water and is draining
KIM [24]
The answer would be 11 gallons.

The tub starts with 32 gallons. Every minute it loses 3 gallons.

So after 1 minute it has lost 3 gallons. For example:
32-3= 29 Meaning that after 1 minute the tub has 29 gallons left.

Now you have to remember that the tub is draining for 7 minutes. So it is losing 3 gallons 7 times, because it loses 3 gallons each minute and there are 7 minutes.

We can use multiplication to find how many gallons the tub loses after 7 minutes. This sign “X” basically means “groups of”. We have 7 groups of 3, or
7 X 3

This is the same as saying we have 3, 7 times. Written like this:

3+3 +3 +3 +3 +3 +3 = 21

So after 7 minutes the tub has lost 21 gallons.

Now we take the original number of gallons and take away what was lost:

32-21=11

So there are 11 gallons left after 7 minutes.

Please let me know if you need any further explanation. Hope this helped.
