As treasurer of his school's FFA club, Kenny wants to buy gifts for all 18 members. He can buy t-shirts for $9 and sweatshirts f

Kenny can buy 15 t shirts and 3 sweatshirts.

Step-by-step explanation:

Given,

Number of members = 18

Cost of each t shirt = $9

Cost of each sweatshirt = $15

Money = $180

Let,

x be the number of t shirts

y be the number of sweatshirts

According to given statement;

x+y=18 Eqn 1

9x+15y=180 Eqn 2

Multiplying Eqn 1 by 9

$9(x+y=18 )\\9x+9y= 162\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(9x+15y)-(9x+9y)=180-162\\9x+15y-9x-9y=18\\6y=18\\$

Dividing both sides by 6

$\frac{6y}{6}=\frac{18}{6}\\y=3$

Putting y=3 in Eqn 1

$x+3=18\\x=18-3\\x=15$

Kenny can buy 15 t shirts and 3 sweatshirts.

The shorter leg of a 30°-60°-90° right triangle measures 5 in. What is the length of the longer leg?

DedPeter [7]

The relationship of the angles to the sides opposite those angles is always:

30°=1, 60°=√3, and 90°=2

So the longer leg can be found using the ratios from above...

L/S=√3/1 and we are told that the shorter side is 5 in so

L/5=√3

L=5√3

So A. is the correct answer.
