The ratio of girls to total number of kids in chorus.
The total number of kids is 68 (43+25) and the ratio of 43 to 68 is greater than 25 to 68.
Answer:
$67.90
Step-by-step explanation:
First lets calculate the subtotal, or the price before the coupon is added:
2(12)+1(28)+1(45)=97
Subtotal: $97.00
Okay Now lets apply the coupon, to do this we'll multiply the subtotal by 0.7 since the coupon removes 30% from the price and 1 - 0.3 = 0.7
97 * 0.7 = 67.9
Total: $67.90

Answer:
y=5/3x-3
Step-by-step explanation:
first, let's put 3x+5y=15 into y=mx+b form
move 3x to the other side
5y=-3x+15
divide by 5
y=-3/5x+3
now, perendicular lines have slopes that are negative and reciprocal.
With our new equation we can automatically find the slope, which would be 5/3.
now, we need to find b
plug the points (3,2) into y=5/3x+b
2=5/3(3)+b
2=5+b
-3=b
so that means that our equation will now be
y=5/3x-3.
Hope this helps!
B*h=A, where b equals the length of the base and h equals the length of the height.
