Melissa wants to buy a new pair of shoes that have an original price of $45. Melissa has a coupon for 20 percent off to use on them, which amounts to a discount of $9. If sales tax is 9 percent on the final price of the shoes, how much tax will she need to pay?
$3.24
$4.05
$4.86
$4.95

Answers

Answer:

$3.24

Step-by-step explanation:

First, we subtract the $9 from the $45, so that equals $36

9% of the 36% is added to the final price as tax

36 x 0.09 = 3.24

Answer:

45-9=36

what we could do is first find out how much 1% is, 36÷1=0.36.

so 0.34×9=3.24

the final answer is 3.24

Answer:

C. His estimate is incorrect; it should be closer to 12 than 11.

Step-by-step explanation:

1. 11^2 is 121, √(140^2) is 140, and 12^2 is 144.

2. Based off these numbers 140 is closer to 144, meaning that √(140) is closer to 12 than 11.

Therefore, the correct answer is C. His estimate is incorrect; it should be closer to 12 than 11.

Answer:

1A. Half jump

1B. 2/3 is half of 4/3

2. 4

Step-by-step explanation:

1A. The remainder of 2/3 is shown in the model by a half jump. It is a half jump because a full jump is 4/3.

1B. We know that the remainder represents 1/2 of the jogging loop because 2/3 is half of 4/3.

2. Convert 2 1/2 into a mixed number with the denominator as eighths. We then get 20/8 divided by 5/8. After that, we can see that 5/8 goes into 20/8 4 times. (5/8 + 5/8 + 5/8 + 5/8 = 20/8)

Let f(x)=-x-5 and g(x)=2x+3. Find the indicated value:
x when g(x)=1

Answers

Answer:

-9

Step-by-step explanation:

few words about function notation.  If f is a function, then f(x) is the

value of the function at x, usually denoted by some sort of rule for finding

the value of the function given that you know the value of x.  f(a) would be  

the value of the function at a, and f(4) would be the value of the function at,

=4

In this case the value of the function f at x, or f(x) is given by the rule:

f(x) = -x - 5   You want to know f(4), which is the value of the function at

4, so f(4) = -(4) - 5 = -9

Step-by-step explanation:

From what I could see it says walked for 14 around her block 4 times so your answer is 3.5 because if (Let's call her Patricia) Patricia walked around her block 4 times in 14 minutes, we have to find the unit rate, therefore we have to divide 14 by 4 as shown below
