Use function notation to represent how much the volume of the box (in cubic inches) changes by if the cutout length increases fr
MakcuM [25]

Answer:

Increases 64 times

Step-by-step explanation:

The volume of the box can be calculated using formula

V=l\cdot w\cdot h,

where

V = volume,

l = length,

w = width,

h = height

If the length was 0.3 inches, then the volume was

V_1=0.3\cdot w\cdot h=0.3wh

When the length became 1.2 inches, then all dimensions became 1.2 :0.3 =4 times greater, then the volume was

V_2=1.2\cdot (4w)\cdot (4h)=19.2wh

The volume increases

\dfrac{V_2}{V_1}=\dfrac{1.92wh}{0.3wh}=64 times

Eric needs 1/2 deck of playing cards for a magic trick. He only has 2/7 of a deck. What fraction of a deck does Eric still need?
tatyana61 [14]

Answer: Eric still needs \frac{3}{14} of a deck.

Step-by-step explanation:

You know that:

- Eric need 1/2 deck of playing cards.

- Eric has 2/7 of a deck.

Therefore, to find the fraction of a deck that Eric still needs, you must subtract 1/2 and 2/7:

- Find the least common multiple of the denominators:

2=2*1\\7=7*1

LCM=2*7*1=14

- Now, you can make the subtraction:

\frac{(7*1)-(2*2)}{14}=\frac{7-4}{14}=\frac{3}{14}

Therefore, he still needs \frac{3}{14} of a deck.
