Multiply the dimensions by 1.5 and Pamela's suitcase becomes 42" x 24" x 12". 

<span>Volume of 28" x 16" x 8": 3584 in^3 </span>

<span>Volume of 42" x 24" x 12": 12,096 in^3 </span>

<span>The volume ratio is 3.375, and yes, you have to cube it.</span>

ok


volume=length times width times height
her current suitcase volume is 28*16*8=3584 cubic inches

her new one will have each dimention mulipled by 1 and 1/2 or 1.5

so
newV=(1.5*28)*(1.5*16)*(1.5*8)
newV=12096 cubic inches


ratio is 12096/3584=3.375=1.5*1.5*1.5


the ratio is new:old=3.375:1

Find the equation of a line that is parallel to the line -3x+2y=10 and goes through the point (0,7).
Delvig [45]

Answer:

  3x -2y = -14

Step-by-step explanation:

The parallel line will have a new constant that can be found by substituting the given point for x and y.

  -3x +2y = -3(0) +2(7) = 14

An equation for the parallel line is ...

  -3x +2y = 14

__

In standard form, the leading coefficient is positive, so the standard form equation is ...

  3x -2y = -14
