15 is the width because 30 times 2 equals 60 and 60 plus 30 equals 90 so 30/2 equals fifteen.

In short-30*2+w2=90

w=15

Hope this helps!

Answer:

<em>V = 65.9 cubic millimeters</em>

Step-by-step explanation:

<u>The Volume of a Right Circular Cone</u>

Given a right circular cone of radius r and height h, its volume is calculated as follows:

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

The cone shown in the image has a radius of r=3 mm and a height of h=7 mm, thus the volume is:

\displaystyle V=\frac{1}{3}\pi\cdot 3^2\cdot 7

Taking pi as 3.14:

\displaystyle V=\frac{1}{3}3.14\cdot 3^2\cdot 7

Calculating:

V = 65.9 cubic millimeters

This is hard can I get help

Same as the last one you asked. 

AB + BC = AC. Just think of it like Part + Part = Whole Thing

(2x + 6) + (6x + 5) = 51

Combine like terms:
8x + 11 = 51

Subtract 11 from both sides to get the variable and its coefficient on its own:
8x = 51 - 11
8x = 40

Divide both sides by 8 to isolate the variable:
x = 5

It's asking for us to find BC so now we plug in x = 5 to the equation it gave for BC. 

6x + 5
6(5) + 5
30 + 5
35

BC is 35 units long.
