Maria has 90$ in a saving account.The interest rate rise a 5% compounded annually.to the nearest cent, how much will he have in 3 years

$104.19

Step-by-step explanation:

We will use the compound interest formula to solve this:

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, lets change 5% into a decimal:

5% -> -> 0.05

Now, plug the values into the equation:

After 3 years, Maria will have $104.19

Explanation:

A rotation is a rigid transformation, which means that it does not change the size, shape, and angles of the figure rotated.

You, then, can assert that after Britton rotated the trapezoid ABCD 180º, its image is a congruent trapezoid.

Since counterparts of congruent figures are congruent and B' is the counterpart of B, you can conclude that the angle B' has the same measurement as the angle B.

Hence, the image of the vertex B, this is vertex B',  will have the same angle as the original.

Given that the angle B is 20º, the degree measurement of its image, angle B', is also 20º.
