1. percent increase : (new number - original number) / (original number)...x 100
<span>(22 - 20) / 20 = 2/20 = 0.1.....0.1 x 100 = 10...so there is a 10% increase</span>
Answer: Length = 15 inches
Width = 12 inches
Step-by-step explanation:
The painting is rectangular.
Let L represent the length of the painting.
Let W represent the width of the painting.
Area of a rectangle = LW
Marisol is panting on a piece of canvas that has an area of 180 square inches. It means that
LW = 180- - - - - - - - - - -1
The length of the painting is 1 and 1 fourth times the width. It means that
L = 1.25W
Substituting L = 1.25W into equation 1, it becomes
W(1.25W) = 180
1.25W² = 180
W² = 180/1.25
W² = 144
W = √144
W = 12 inches
L = 1.25W = 1.25 × 12
L = 15 inches
Answer: 64
Step-by-step explanation:
2^3 = 8
2^-3=1/8
8/1/8=64
Answer:
20 minutes; 240 barrels
Step-by-step explanation:
Old line = 40 + 10t
New line = 12t
Equal when,
40 + 10t = 12t
40 = 2t
t = 20 minutes
Each line will have:
12t = 12(20) = 240 barrels
