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.

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.

your welcome :)

2% of 12,560 would give you 251.2 and 251.2 X 4 = 1004.8 so your answer is B

6. How are slope and rate of change similar ? ( use complete sentence to explain )

Answers

Answer:

Finding Rate of Change. When finding the slope of real-world situations, it is often referred to as rate of change. “Rate of change” means the same as “slope.” If you are asked to find the rate of change, use the slope formula or make a slope triangle.

Step-by-step explanation:

The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . .... if coordinates of any two points of a line are given, then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.
