Answer:

When the graph of the linear relationship contains the origin, the relationship is proportional. A linear equation is an equation whose solutions are ordered pairs that form a line when graphed on a coordinate plane. A relationship may be linear but not proportional and the graph does not pass through the origin.

A cubic inch of PVC material weight 0.063 pounds per cubic inch. What’s the weight of a 36 inch piece of PVC pipe with an outsid

artcher [175]

Answer:

Option B. 0.783 pounds

Step-by-step explanation:

step 1

Find the area of a a 36 inch piece of PVC pipe with an outside diameter of 0.82 inches and an inside diameter of 0.75 inches

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r2=0.82\ in$

$r1=0.75\ in$

assume

$\pi =3.14$

$A=\pi (r2^2-r1^2)$

substitute the values

$A=(3.14)(0.82^2-0.75^2)$

$A=0.345086\ in^2$

step 2

Find the volume of the piece of PVC

Multiply the area by its length

$V=0.345086(36)=12.42\ in^3$

step 3

Find the weight of the piece of PVC

Multiply the volume by its density

The density is $0.063\frac{lb}{in^3}$

so

$W=12.42(0.063)=0.783\ lb$
