Hi, thank you for posting your question here at Brainly.

This problem could be solved using the Law of Cosines, since we are given with the three sides. The equation goes,

b^2 = a^2 + c^2 - 2accosB. Substituting,

24^2 = 7^2 + 25^2 - 2(7)(25)cosB

Then B = 73.7 degrees. Therefore sinB or sin(73.7) = 0.96.

Given Information:

Years = t = 35

Semi-annual deposits = P = $2,000

Compounding semi-annually  = n = 2

Interest rate = i = 6.5%  

Required Information

Accumulated amount  = A = ?

Answer:

Accumulated amount  = $515,827

Step-by-step explanation:

The future value of amount earned over period of 35 years and interest rate 6.5% with semi-annual deposits is given by

FV = PMT * ((1 + i/n)^nt - 1)/(i/n))

Where  

n = 2

i = 0.065

t = 35

FV = 2000*((1 + 0.065/2)^2*35 - 1)/(0.065/2))

FV = 2,000*(257.91)

FV ≈ $515,827

Therefore, Anthony will have an amount of $515,827 when he retires in 35 years.

So 13 divided by 3 is 4 but where is the 4 coming from because 4 groups of 3 is 12 so 13 minus 12 is 1 so how dose the 4 make it
Crazy boy [7]
13/3= 4.25 because.....



13-12 is 1.

SO:


When you have your problem  set up, you have 4, and then a 1 left over. You turn it into a fraction.


Make 4 and 1/4, then put it as a mixed number, 4 1/4



or you can keep dividing by adding a decimal then zeroes and keep solving until you get 4.25 which is equivalent to 4 1/4
