Using the lowest common factor as 10.

Expressing it, 3/10 + 2/5

(10 into 10 times 3) plus ( 5 into 10 times 2)

= 3 plus 4, all over 10

The volume of a box (v) varies directly with its length (l) if one of the boxes has a volume of 325 cubic inches and a length of

stiks02 [169]

Answer:

The constant of proportionality for the group of boxes is: 25

Step-by-step explanation:

Proportion means that change in one quantity causes change in other quantity. Direct variation means that increase in one quantity causes increase in the other quantity.

Let l be the length and v be the volume

Then according to given statement

V∝l

Removing the proportionality symbol introduces a constant in the equation

$V = kl$

Putting V = 325 and l = 13

$325 =k(13)\\k = \frac{325}{13}\\k = 25$

Hence,

The constant of proportionality for the group of boxes is: 25

Answer:

y intercept=15 and slope is 3

Step-by-step explanation:

Ok so for this one we know the y intercept is 15 because the y intercept is wherever x=0 and in the table when x=0 y=15

to find slope we use (y2-y1)/(x2-x1) which when we put points (0,15) and (1,18) in for would be:

(18-15)/(1-0)
