Lori is three times as old as Michelle. In five years Michelle's age will be one half of Lori's age. How old are Lori and Michel

AURORKA [14]

Answer:

Lori's age is 15 years old and Michelle's age is 5 years old now

Step-by-step explanation:

Let

x-----> Lori's age

y ----> Michelle's age

we know that

$x=3y$ -----> equation A

$(y+5)=\frac{1}{2}(x+5)$ ----> equation B

substitute equation A in equation B and solve for y

$(y+5)=\frac{1}{2}(3y+5)$

$2y+10=(3y+5)$

$3y-2y=10-5$

$y=5$

Find the value of x

$x=3(5)=15$

therefore

Lori's age is 15 years old and Michelle's age is 5 years old now

A right triangle has leg measures of 8 and 15 inches. What is the area and perimeter of the triangle?

rewona [7]

Hello!

<h3><em><u>Answer</u></em></h3>

The area of the right triangle is 30 $in^{2}$ . The perimeter is 40 in.

<h3><em><u>Explanation</u></em></h3>

First, we must find the measure of the hypotenuse of the triangle by using the Pythagorean Theorem.

$a^{2}$ + $b^{2} = c^{2}$

$8^{2} + 15^{2} = c^{2}$

64 + 225 = $c^{2}$

√289 = $c^{2}$

17 = $c$

Now that we have all the side lengths, we can use the formulas to find the area and perimeter.

A = $\frac{bh}{2}$

A = (15 × 8) ÷ 2

A = 30

<h3>PERIMETER:</h3>

P = a + b + c

P = 8 + 15 + 17

P = 40
