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

Determine the measure of the missing angle in each triangle? <br> Please help me ASAP
IrinaK [193]

Answer:


Step-by-step explanation:

Sum of angles in a triangle = 180

1. 180 = 78 + 37 + x

180 = 115 + x

Subtract 115 from both sides

180 - 115 = 115 + x - 115

180 - 115 = x

65 = x

x = 65°


2. 180 = 80 + 66 + x

180 = 146 + x

Subtract 146 from both sides

180 - 146 = 146 + x - 146

34 = x

x = 34°
