30 POINTS!!!!!!!! JoeNah, DeKobian and Evan wrote equations to calculate the amount of money in a savings account after one year

castortr0y [4]

Answer:

See the explanation for the answer to this question

Step-by-step explanation:

Let

B ---> the balance of money saved.

M ---> the amount invested in dollars

JoeNah's Equation

M=$100

$B=1.5(100)=\$150$

Dekobian's Equation

M=$100

$B=100+0.05(100)=\$105$

Evan's Equation

M=$100

$B=M(1+0.05)$

Substitute

$B=100(1+0.05)=\$105$

Dekobian's equation and Evan's equation are correct! :)

JoeNah's equation is wrong. :(

Hope this helps you!

Have a good evening!

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Define

Leg a = 8

Leg b = 4

Hypotenuse c = x

Step 2: Solve for x

Substitute in variables [Pythagorean Theorem]: 8² + 4² = x²
Evaluate exponents: 64 + 16 = x²
Add: 80 = x²
[Equality Property] Square root both sides: √80 = x
Rewrite: x = √80
Simplify: x = 4√5
