Answer:

a = 7

Step-by-step explanation:

3a + 4 = a + 18

Add -a and -4 on both sides.

3a - a = 18 - 4

2a = 14

Divide 2 into both sides.

a = 14/2

a = 7

A 10-year annuity pays $1,850 per month, and payments are made at the end of each month. If the APR is 12 percent compounded mon
Fittoniya [83]

Based on the amount the annuity pays per month and the APR, the value of the annuity today is $133,349.85.

<h3>What is the present value of the annuity?</h3>

First, find the present value of the annuity at 5 years:

= 1,850 x present value interest factor of annuity, 60 months, 8/12%

= 1,850 x 49.32

= $91,242

Then find the present value of the annuity from 5 years till date:

= (1,850 x present value interest factor of annuity, 60 months, 12/12%) + ( 91,242) / (1 + 1%)⁶⁰)

= (1,850 x 44.955) +  ( 91,242) / (1 + 1%)⁶⁰)

= $133,349.85

krek1111 [17]

Answer:

5391.76

Step-by-step explanation:

We have a rectangle and 2 semicircles

First find the area of the rectangle

A = l*w

A = 44*88= 3872

Then we know that 2 semicircles = 1 circle

The area of a circle is

A = pi r^2

The diameter is 44 so the radius is 22

A = pi * 22^2

A = pi484

A =1519.76

Add the areas together

1519.76+3872
