Meredith borrows $12,560 and pays 2 percent simple interest each year for 4 years. What is the total amount of interest that she will pay on the loan?
$251.20
$1,004.80
$11,555.20
$13,564.80

Answers

Meredith borrow 12,560 so if you do some basic calculations, %2 of that is 251.20 dollars of interest per year

The total amount of interest she will pay for 4 years (251.20 x 4) is 1004.80 dollars for 4 years.

Question 8:B
Question 5:C
For question 8, you want to can’t how much it rises first and how many spaces you have to go over second. When ever you count the amount of spaces to move horizontally you always count left to right. So you start at the point furthest to the left, and since that point is higher instead of counting up to the next point you have to count down, which means it is going to be a negative number. You count down 5 spaces, and then right 4 spaces to get to the next point which means the slope is -5/4.
For question 5, it is the same concept so from the left point you have to go down 2 and over 8, which makes the slope -2/8 but you have to simplify it to make it -1/4. The y-intercept is -1.5 because that is where the line crosses the y-axis

Cormac is making 31 phone calls each week as part of a fundraiser. Last week, he made 8 phone calls on weekdays. Which equation could be used to find x, the number of phone calls he made last week on weekend days? HELPP

Answers

Answer: k-y

Step-by-step explanation: Let's call the overall phone calls made every week 'k', and the phone calls made on the weekdays 'y'. Since 'x' is the number of phone calls made per weekend, y+x should equal k. But we don't know what x is so we need to make x the subject, which would be x = k-y.

e.g: k=31, y=8:

31-8= 23 phone calls made on the weekend.

In ΔABC, point M is the midpoint of side AB and point D is the midpoint of segment MC. Prove that the area of ΔADC= the area of ΔBMD

Answers

A line segment from a vertex to the midpoint of the opposite side is a "median". A median divides the area of the triangle in half, as it divides the base in half without changing the altitude.
AAMC is half AABC. AADC is half AAMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
ABMC is half AABC. ABMD is half ABMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
Then, AADC = 1/4 AABC = ABMC, so AADC = ABMC by the transitive property of equality.
