Answer:

JM = 20

Step-by-step explanation:

Find the value of JM

Using similar triangles;

MJ/HN = GJ/HK

GJ+JM/HN = GJ/HK

15+JM/12+16 = 15/12

15+JM/28 = 15/12

Cross multiply

12(15+JM) = 15*28

180+12JM = 420

12JM = 420 - 180

12JM = 240

JM = 240/12

JM = 20

<em>Hence the length of JM is 20</em>

Caiden earned $475 from mowing lawns last summer. He deposited this money in an account that pays an interest rate of 3.8% compo
Korolek [52]

Caiden's balance after 5 years would be $831

<u>Explanation:</u>

Given:

Principal, p = $475

Rate of interest = 3.8%

time, t = 15 years

Balance after 15 years = ?

We know:

Amount, A = P(1+\frac{r}{n})^n^t

where,

n = number of compounding periods

r = rate of interest

t = number of years

Substituting the value;

A = 475(1+\frac{3.8}{100} )^1^5\\\\A = 831

Therefore, Caiden's balance after 5 years would be $831
