Answer:

100 degrees

Step-by-step explanation:

The three angles inside a triangle always add up to 180

so, 180-43-57 is 80

But that's the angle inside the triangle. notice that that angle (ACD) and BCA make a straight line.  That means they add up to 180. Therefore, 180-80=100 degrees.

Fatima opened a savings account with $7,500. She decided to deposit that same amount semiannually. This account earns 3.975% int
docker41 [41]

Answer:

A = $11117.25

Step-by-step explanation:

Given the following data;

Principal = $7,500

Interest rate = 3.975% = 3.975/100 = 0.03975

Number of times, n = 2

Time, t = 10 years

To find the future value, we would use the compound interest formula;

A = P(1 + \frac{r}{n})^{nt}

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

A = 7500(1 + \frac{0.03975}{2})^{2*10}

A = 7500(1 + 0.019875)^{20}

A = 7500(1.019875)^{20}

A = 7500(1.4823)

A = $11117.25

Alekssandra [29.7K]

Answer:

  28th

Step-by-step explanation:

Put that value into the formula and solve for n.

  191 = 2 +7(n -1)

  (191 -2)/7 = n-1 . . . . . . . subtract 2 and divide by 7

  27 +1 = n . . . . . . . . . . . .add 1

191 is the 28th term in the sequence.
