Option A
The simple interest earned over 6 years is $ 4050
<em><u>Solution:</u></em>
Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year
<em><u>The formula for simple interest is given as:</u></em>

Where, "p" is the principal and "n" is the number of years and "r" is the rate of interest
From given,
p = 15000
r = 4.5 %
n = 6 years
<em><u>Substituting the values we get,</u></em>

Thus simple interest earned over 6 years is $ 4050

Answer:
c = 10 feet
Step-by-step explanation:
Use the Pythagorean theorem: a^2 + b^2 = c^2
<u>Step 1: Plug in the information</u>
(6)^2 + (8)^2 = c^2
36 + 64 = c^2
100 = c^2
sqrt(100) = sqrt(c^2)
<em>10 = c</em>

Answer: c = 10 feet

Answer:
x = 118 degrees approximately
Step-by-step explanation:
Here, we want to get the measure of the angle marked x
We shall use the side facing it and apply the cosine rule
The side facing the angle measures 90
Thus, we have it that;
90^2 = 55^2 + 50^2 - 2(50)(55) cos X
2575 = - -5,500 cos X
X = cos^-1(-2575/5,500)
X = 118 degrees approximately
