The volume of a pyramid is:

V = (length * width * height of pyramid)/3

Note that:

length = 8

width = 8

height of the pyramid = 3

height of the triangle = 5

Solve for Volume:

Multiply

V = (8 * 8 * 3)/3

V = (192)/3

Divide

V = (192)/3

V = 64

Elliott has some yarn that she wants to use to make hats and scarves. Each hat uses 0.2, point, 2 kilograms of yarn and each sca
sp2606 [1]

Answer:

Elliot will make 4 hats and 16 scarves

Step-by-step explanation:

Let x be the number of hats and y be the number of scarves Elliot will make.

Elliott wants to make a total of 20 items, then

x + y = 20

Each hat uses 0.2 kilograms of yarn, so x hats use 0.2x kilograms of yarn and each scarf uses 0.1 kilogram of yarn, then y scarves use 0.1y kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats, then

0.1y = 2(0.2x)

Thus,

0.1y = 0.4x

y = 4x

Substitute it into the first equation:

x + 4x = 20

5x = 20

x = 4

y = 20 - 4

y = 16

Hence, Elliot will make 4 hats and 16 scarves

\frac{3n^{2} - n}{n^{2} - 1} \div \frac{n^{2}}{n + 1}
\frac{n(3n) - n(1)}{n^{2} + n - n - 1} \div \frac{n^{2}}{n + 1}
\frac{n(3n - 1)}{n(n) + n(1) - 1(n) - 1(1)} \div \frac{n^{2}}{n + 1}
\frac{n(3n - 1)}{n(n + 1) - 1(n + 1)} \div \frac{n^{2}}{n + 1}
\frac{n(3n - 1)}{(n - 1)(n + 1)} \div \frac{n^{2}}{n + 1}
\frac{n(3n - 1)}{(n - 1)(n + 1)} * \frac{n + 1}{n^{2}}
\frac{3n - 1}{n - 1} * \frac{1}{n}
\frac{3n - 1}{n(n - 1)}
