B/h=3/8
8b=3h
8/3b=h
P=2(h+b)
P=138.6
138.6=2(h+b)
divide both sides by 2
69.3=h+b
suub (8/3)b for h
69.3=(8/3)b+b
times both sides by 3 to get rid of fraction
207.9=8b+3b
207.9=11b
divide both sides by 11
18.9=b
sub back
(8/3)b=h
(8/3)18.9=h
50.4=h
area=height times base
aera=50.4 times 18.9
aera=952.56 cm²
1. base=18.9 cm
2. height=50.4 cm
3. area=952.56 cm²
Answer:A
Step-by-step explanation:
18-(3xeach #)=
All are less than 10
The correct answer is the first option, which is:
A=G^2/H; H=G^2/A
The explanation is shown below:
1. To solve the exercise shown in the figure attached, you must apply the proccedure shown below:
2. You have the following equation to calculate G:
G=√AH
3. Now, to find the formula to calculate A, you must clear the A, as below:
G^2=(√AH)^2
G^2=AH
A=G^2/H
4. Then, you must apply the same proccedure to find the formula for calculate H, as following:
G^2=(√AH)^2
G^2=AH
H=G^2/A
The discount is 40% that means the discount is 40% off from the original price. Or we could write the discount as below.
discount = 40% × original price
Find the original price
original price = sale price + discount
original price = 36 + 40% original price
100% original price = 36 + 40% original price
100% original price - 40% original price = 36
60% original price = 36
0.6 original price = 36
original price = 36/0.6
original price = 60
The original price of the headphone is $60
