if Sonja makes $2100 interest after investing $15,000 at 2.8%, how many years did she invest for?

Answers

Answer:

Sonja invested for 5 years.

Step-by-step explanation:

First you have to find how much money she gets in one year.

To do this you would have to multiply 15,000 and 2.8.

15,000 x 2.8 = 42000

You move the decimal 2 spaces forward since there are 3 zeros in 15,000 and one decimal place in 2.8.

This gives you 420.

To find how many years it takes for her to make $2100 you have to divide

2,100/420.

This gives you 5, which means that she invested for 5 years.

Gracie’s bill at a restaurant is $15. Sales tax is 6% and she plans to leave a 20% tip (on the total after tax is added). What is the total amount of money she’ll pay, including tax and tip?

Answers

sales tax would be 0.90 then add the 20% would be 3.00 so 15 + 0.90 + 3 = ur answer

Answer:

She will pay $19.08

Step-by-step explanation:

6/100=0.06

15(0.06)=0.90

15.00+0.90=15.90

20/100=0.2

(15.90)(0.2)=3.18

15.90+3.18=$19.08

You need to find a common denominator I chose 28 so I multiplied 4 by 7 and that gives you 28 and you have to do the same thing to the top that you did to the bottom so I multiplied 11 by 7 as well which gave me a fraction of 77/28 then I multiplied 7 by 4 to get 28 and multiplied the top by 4 to get a fraction of 20/28 then I added 8 to 20/28 and to 77/28 to get 28/28 (the whole fence) and 85/28 (the paint you need to cover the whole fence) then I simplified my answer by seeing how many times 28 fit into 85 and it fits 3 times with a remainder of 1 so the simplified answer I got was 3 and 1/28 gallons of paint to cover the whole fence.

The side length of a square is 7 units. The square is reflected over the x-axis in the coordinate plane.

What is the length of the side of the image?

Answers

I believe the answer is 7

Explanation- a square reflected will have the same lengths and widths also we know that a square side are all the same.

The length of the side of the image is 7 units.

What is the reflection on x-axis?

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

Given that, the side length of a square is 7 units.

The square is reflected over the x-axis in the coordinate plane.

A reflection is an isometry, which means the original and image are congruent, that can be described as a "flip".

Therefore, the length of the side of the image is 7 units.

Data Set: 5, 8, 10, 10, 15, 18, 23. What is the upper quartile limit (Q3) of this data set? *

Answers

Answer:

15, 18, and 23

Answer:

Q₃ = 18

Step-by-step explanation:

The first step is to find the median

The median is the middle value of the data in ascending order.

5, 8, 10, 10, 15, 18, 23

↑ middle value

median = 10

The upper quartile Q₃ is the middle value of the data to the right of the median, that is

15, 18, 23

↑ middle value

Thus Q₃ = 18
