Answer:6x+126in^2
Step-by-step explanation:
a =15 long
b=x. Wide
A=ax
A=15x represenrs picture area
Add on each side of picture 3 in
a1=15+6=21 in
b1=x+6
Calculate area
A1=a1b1
A1=21(x+6)
Area of frame = A1-A
Area of frame=21(x+6)-15x=21x-15x+126=6x+126in^2
A: (x^a) / (x^a) = x^(a - a) = x^0
B: Anything divided by itself is 1, so x^a / x^a = 1.
C: If x^a / x^a = x^0 from Part A and x^a / x^a = 1 from Part B, then x^0 = 1.
Reflect: 1. To complete Part A, we used the quotient rule for exponents.
Hope this helps!
The is 42 because that the answer to the question
So basically, he wants to make mixture where lemon=lime
it is 6 gallons so
40% of 6=0.4 times 60=2.4=lemon
60% of 6=0.6 times 60=3.6=lime
so to make them equal
3.6-2.4=1.2
he must add 1.2 gallons of 100% lemon juice to make a mixture of 50% lemon and 50% lime
1.2 gallons is the answer
Answer:
The answer to your question is 20 in
Step-by-step explanation:
Data
ratio 1 : 30
real length = 55 ft
toy train length = ?
Process
1.- Use ratio and proportions to solve this problem.
1 : 30 :: x : 55
solve
x = (55 x 1) / 33
Simplification
x = 55/33
result
x = 1.67 ft
2.- Convert the length to in
1 ft ------------------ 12 in
1.67 ft -------------- x
x = (1.67 x 12) / 1
-Simplification
x = 20/1
-Result
x = 20 in
