Answer:

(3x + 5) + (x +3) = 180 sum of angles on a

straight line

3x + 5 + x + 3 = 180

3x + x + 5 + 3 = 180

4x + 8 = 180

4x = 180 - 8

x = 172/4

x = 43

PQR = 3x + 5 = 3(43) + 5 = 129 + 5 = 134

Describe how multiplying all the linear dimensions of a cone by one

Anton [14]

Answer: $\frac{1}{64}^{th}$

Step-by-step explanation:

Given

Suppose V is the original volume of cone having r as radius and h as height

If we multiply all the linear dimensions of ac one by $\frac{1}{4}^{th}$

the $r'=\frac{r}{4}$

$h'=\frac{h}{4}$

Therefore new volume is

$V'=\frac{1}{3}\pi r'^2h'$

$V'=\frac{1}{3}\pi (\frac{r}{4})^2(\frac{h}{4})$

$V'=\frac{1}{64}\times \frac{1}{3}\pi r^2h$

$V'=\frac{V}{64}$

So new volume becomes $\frac{1}{64}^{th}$ of the original one
