Answer:
Area of ΔABC = 144 ft^2
Step-by-step explanation:
ΔABC is 45 45 90 right triangle
Ratio of leg (AC, BC) : hypo (AB) = x : x√2
Given hypo AB = 24 so AC = BC = 12√2
Area of ABC = 1/2 bh
= 1/2 ( 12√2)( 12√2)
= 1/2(144 * 2)
= 144 ft^2
Answer:
28%
Step-by-step explanation:
start with $46 = 100% of starting price
coupon = 40% off starting price
40% off of 100% = 100% - 40% = 60% of starting price = price after coupon
60% = 0.6
60% of starting price = price after coupon = 0.6 * $46 = $27.6
then, a 20% processing fee is applied to the price after the discount
new price = $27.6 = 100% of new price
fee = 20% added to new price
20% added to new price = 100% + 20% = 120% of new price
120% = 1.2
final price = price after fee = 120% of new price = 1.2 * $27.6 = $33.12
change in percentange = (original price - new price) / original price * 100
= ($46 - $33.12) / $46 * 100 = 28%

Answer:
-3ad/2 -2bd = c
Step-by-step explanation:
3a + 4b = 1 - 2c/d
⇒3ad + 4bd = d - 2c [multiply d on both sides]
⇒3ad + 4bd - d = -2c [subtract d on both sides]
⇒3ad/(-2) + 4bd/(-2) = c [divide -2 on both sides]
⇒-3ad/2 -2bd = c
