A.
$679.80

B.
$615.25

C.
$690.00

D.
$650.50

Answers

Answer 1
The answer would be A)$679.80
The reason for this is let’s start with the mark up of 10%. Meaning we will add the result of the markup to our first number We would take 1000*.1 which would give us 100.
Add that to the original to give you $1,100.
Then the item was discounted for 40% meaning we take away the result of 1,100*.4 which equals 440. 1100-440=660.
Then taxes are added on to the total so you would do 660*.03 which would give you 19.8
660+19.8 gives you$679.80.
Answer 2
the answer is A i hope this helped

I know I already asked this but I need an explanation on whyyy

The question is: There are 28 girls and 22 boys on a swim team what percent of the team is made up of boys? explain why pls.

Answers

Answer:

U first need to find out the total number of people

22+28

50

and since they are asking only for boys we need to put the number of boys on the numerator and the total number of people at the denominator

22/50

And now to make it into % we need to ALWAYS multiply the fraction by 100

22/50 x 100

44%

Hope it helps

Answer:

44 %

Step-by-step explanation:

okay so 100% is equal to the whole team or 50 swimmers

100% = 50 swimmers

to find out how much one swimmer is would be to divide the 100% by the total of swimmers.

100% / 50 swimmers

2% = 1 swimmer

so now that we know how much percent 1 swimmer is we will multiply 2% by 22, the number of boy swimmers.

2 x 22 = 44

HELP ME ON ALEKS HW The figure below has a point marked with a large dot. First, translate the figure 7 units down. Then, give the coordinates of the marked point in the original figure and the final figure.​

Answers

is there suppost to be a picture because i dont see it..

Answer:

Original: (1,1)   Final: (1,-6)

Step-by-step explanation:

When you translate a shape on a coordinate plane, you are moving it vertically or horizontally, without changing it in any way (you are NOT rotating, reflecting, or dilating).

If we look at the large dot on the image, we see it is at (1,1). To move it down 7 units, count down seven units from the dot, and you will get (1,-6).

The histogram below shows information about the hours students spent exercising in a week:

A histogram is titled Weekly Exercise, the horizontal axis is labeled Hours of Exercise, and the vertical axis is labeled Students. The range on the horizontal axis is 0 to 4, 5 to 9, and 10 to 14. The values on the vertical axis are from 0 to 10 at intervals of 1. The first bin goes to 4, the second bin to 9, the third bin to 5.

Which information is provided in the histogram?

A:The number of students who exercised 4 hours or more
B: The number of students who exercised 9 hours or fewer
C:The mean hours of exercise
D:The median hours of exercise

Answers

Answer: A

Step-by-step explanation: with my calculation, and the information you have give i have to say it is A.

Answer:

C and D are somewhat correct. We may be able to estimate the mean and median hours from the histogram.

A seems to the closest answer, but not exactly correct.

Step-by-step explanation:

It seems that none of the descriptions is exactly right. The first bin is 0 to 4 hours, so the "4 hours or more is not accurate. The third bin is 10 to 14 hours, so B is wrong.
