A candle is in the shape of a square prism. The candle is 16 meters high, and its volume is 960 cubic meters. Find the length of
madam [21]

Answer:

The length of each side of the square base is 2\sqrt{15}\ m

Step-by-step explanation:

we know that

The volume of a square prism is equal to

V=b^{2}h

where

B is the length side of the square base

h is the height of the prism

we have

V=960\ m^{3}

h=16\ m

substitute and solve for b

960=b^{2}16

b^{2}=960/16

b=\sqrt{60}\ m

Simplify

b=2\sqrt{15}\ m

Five yards of material is needed to make
Mkey [24]

Answer:

The y-coordinate would be 17.5

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

y ----->material needed in yards

x ----> number of curtains

we know that

For y=5, x=2

Find the value of the constant of proportionality k

k=y/x

substitute the given values of x and y

k=\frac{5}{2}=2.5

The linear equation is equal to

y=2.5x

If the x-coordinate was 7

then

substitute in the equation x=7 and solve for y

y=2.5(7)

y=17.5

therefore

The y-coordinate would be 17.5
