125/x=100/20
(125/x)*x=(100/20)*x - we multiply both sides of the equation by x
125=5*x - we divide both sides of the equation by (5) to get x
125/5=x 
25=x 
x=25
Hope this helps

Find the length of the hypotenuse of a right triangle whose legs have lengths 4 and 8

Ya gotta use the Pythagorean theorem :)

a² + b² = c² (reminder: c is the hypotenuse)

4² + 8² = c²

16 + 64 = 80

√80 = 8.94

H = 8.94

An investment of $900 earns 6% annual interest and is compounded semi-annually. Write an equation

nalin [4]

Answer:

$A=900(1+\frac{0.06}{2})^{2(t)}$

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

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

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 6% into a decimal:

6% -> $\frac{6}{100}$ -> 0.06

Since the interest is compounded semi-annually, we will use 2 for n. Lets plug in the values now and your equation will be:

$A=900(1+\frac{0.06}{2})^{2(t)}$

You deposit $5000 in an account earning 8% interest compounded monthly. How much will you have in the account in 15 years?
