If $11,100 is invested at 3.1% interest compounded monthly, how much will the investment be worth in 19 years?

In 19 years, the investment will be worth $19973.34

Step-by-step explanation:

The compound interest formula is :

p = 11100

r = 3.1% or 0.031

t = 19

n = 12 (compounded monthly)

Now, putting these values in the formula we get;

=>

A = $19973.34

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

i believe it's a.

i'm not sure on this one, most likely correct.
