<h2>Part A</h2>

Use Pythagorean theorem to confirm the right triangle:

AB² + BC² = AC²

12² + 5² = 13²
144 + 25 = 169
169 = 169

Confirmed

<h2>Part B</h2>

The triangles are similar:

ΔABC ~ ΔRST

Corresponding sides have same ratio:

AB/RS = AC/RT

Substitute known values and find the missing length:

12/24 = 13/RT
1/2 = 13/RT
RT = 13*2
RT = 26

Area of a triangle

$\frac{bh}{2} \\ 10 \times 10 = 100 \\ 100 \div 2 = 50 \\ the \: triangles \: have \: the \: same \: area \: and \: there \: are \: 4 \: triangles \: so \\ 4(50) = 200 \\ now \: we \: find \: the \: are \: of \: the \: rectangular\: base \: \\ area = bh \\ b = 10 \\ h = 10 \\ 10(10) = 100 \\ no w \: we \: add \: the \: area \: of \: the \: triangles \: and \: the \: square \\ 200 + 100 = 300 \: {in}^{2}$

A game store charges a monthly membership fee of $7.50, but then the charge to rent a game is only $1.00. Another store has no m

Eduardwww [97]

Answer:

6 games.

Step-by-step explanation:

Given that,

Monthly membership fee of store 1 is $7.5, but then the charge to rent a game is only $1.00

Another store has no membership fee, but that store charges $2.00 to rent a game.

Let there be n games needed to be rented each month for the total fees to be the same from either store.

Cost of first store = $7.50+$1.00n

Cost of another store = $2.00

If cost equals,

$7.50+$1.00n=$2

n=5.5 $\approx$ 6

Hence, 6 games needed to be rented each month.
