The first step to determine the percentage of increase is to
compute for the difference of consumer price index in value.
231.11 (consumer price index for 2012) – 211.4 (consumer
price index for 2007) = 19.71 (increase)
To compute for the percentage of increase, you need to
compare the increase to the consumer price index for 2007.
19.71/211.4 = 9.3% increase
I pretty sure the answer is c
Answer:
Leg1 = 9 and leg2 = 12
Step-by-step explanation:
<u>Points to remember</u>
<u>Pythagorean theorem</u>
Hypotenuse² = Base² + Height²
<u>To find the length of each leg</u>
It is given that, hypotenuse = 15 feet
Let base = x the height = x +3
By using Pythagorean theorem we can write,
Hypotenuse² = Base² + Height²
15² = x² + (x + 3)²
225 = x² + x² + 6x + 9
2x² + 6x + 216 = 0
x² + 3x + 108 = 0
By solving we get x = 9 and x -12
Therefore one leg = 9 and other leg = 9 + 3 = 12
Answer:
3.75 cubic inches
Step-by-step explanation:
Volume = length x breadth x height
since the box holds 2 layers of 15 cubes
length contains 5 cubes= 5x1/2 inches=2.5 inches
breadth contains 3 cubes=3x1/2inches=1.5 inches
height contains 2 cubes=2x1/2inches=1.0 inches
Volume=2.5x1.5x1.0=3.75 cubic inches
Step-by-step explanation:
=(y-y1)=Y2-Y1/X2-X1(X-X1)
