### How to determine the amount in five years?

The given parameters about the compound interest are

Principal Amount, P = \$500

Interest Rate, R = 8%

Time, t = 3

Compound interests are different from simple interest, and they are calculated using the following compound interest formula

CI = P(1 + R)^t - P

To calculate the amount, we have:

A = P + CI

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

Substitute the known values in the above equation

A = 500 * (1 + 8%)^3

Express 8% as decimal

A = 500 * (1 + 0.08)^3

Evaluate the sum

A = 500 * (1.08)^3

Evaluate the exponent

A = 500 * 1.259

Evaluate the product

A = 629.86

Hence, the value of the investment after 3 years is \$629.86

Step-by-step explanation:

Lea walked 1/2 miles in 1/3 hours. How long will it take Lea to walk 2 1/4 miles?
Enter your answer as a mixed number in simplest form in the box.

(1/2) / (1/3) = (2 1/4) / x......1/2 mile to 1/3 hr = 2 1/4 miles to x hrs
cross multiply because this is a proportion
(1/2)(x) = (1/3)(9/4)
1/2x = 3/4
x = 3/4 * 2/1
x = 6/4 = 1 1/2.....so it will take 1 1/2 hrs

It will take Lea 1 1/2 hours to walk 2 1/4 miles.

What+8,477.6=10,248 what+0.07=0.1

x+8477.6=10248
-8477.6    -8477.6     1770.4+8477.6=10248
x=1770.4

x-0.07=0.1
+0.07   +0.07         0.17-0.07=0.1
x=0.17
Question one: x + 8477.6 = 10248

x+8477.6=10248

Subtract 8477.6 from both sides.

x+8477.6−8477.6=10248−8477.6

x=1770.4

S0 1770.4 + 8477.6 = 10248

Question two: x + 0.07 = 0.1

x+0.07=0.1

Subtract 0.07 from both sides.

x+0.07−0.07=0.1−0.07

x=0.03

So 0.03 + 0.07 = 0.1

What is the reflection image of (5,-3) across the line y = -x?

y=-x
(X,Y) will change to -> (-y,-x)

(5,-3) will change to ->(3,-5)

-3 changed to 3 because -(-3) = 3
