Answer:
$0.61
Step-by-step explanation:
1. Find the sales price of each store by multiplying the regular price by the % off to find the discount - then subtract.
store A: 24.95*20% (or 0.20) = 4.99 (discount)
24.95 - 4.99 = 19.96 (sales price)
store B: 25.80 * 25% (or 0.25) = 6.45 (discount)
25.80 - 6.45 = 19.35
To find the difference of sales price, subtract 19.96 - 19.35 = 0.61
I redrew the triangle (just turned it around it make it easier to understand).
Answer:
A = -y^2 + 18
y = 9 + (81 - x)^(1/2) and y =9 - (18 - x) ^(1/2)
Step-by-step explanation:
Given:
P = 2 ( l + w)
x = length and y = width
P = 2 (x + y)
36/2 = x + y
x + y = 18
x = 18 - y
<u>Area:</u>
A = x * y
A = (18 - y) * y
A = 18y - y^2
Using quadratic formula (<u>solve for y</u>):
y = 9 + (81 - x)^(1/2) and y =9 - (18 - x) ^(1/2)
