What expression represents the volume of the cone, in
denis23 [38]

The expression that represents the volume of the given cone, in cubic units is 2/3 πx³.

<h3>How to calculate the volume of the cone?</h3>

The volume of a cone with radius 'r' and slant height 'h' is

V = 1/3 π r² h

Unit: cubic units

<h3>Calculation:</h3>

The given cone has radius r = x and height h = 2x

Then, the volume of the cone is calculated by

V = 1/3 π r² h

   = 1/3 π x² (2x)

   = 2/3 π x³ cubic units

Therefore, the volume of the given cone is V = 2/3 π x³ cubic units.

So, option A is correct.

Jennifer belongs to a gym that requires a monthly membership fee of $100 plus an additional $10 fee for each yoga class she atte
MrRissso [65]
First of all, we need to know what is the slope-intercept form which is:
y=mx+b where m represent slope and b represent y intercept
Then,
Let y represent the total amount of money that Jennifer pays monthly
mx represent the total amount of money that Jennifer pays for classes she attends
b represent the memberships fee, so:
y=10x+100 the following slope-intercept form equations models the total amount that Jennifer pays monthly. Hope it help!

I need help with 8 i don't understand it i get. idk how to figure out what jm is
Misha Larkins [42]
The segment bisector of line JK would be L since it passes through M
How to find JM is that you would have to solve 3x+15=8x+25 to get x and once you find x you just plug it into the equation for JM, 3x+15
3x+15=8x+25 (subtract 8x on both sides)
-5x+15=25 (subtract 15 on both sides)
-5x=10 (Divide on both sides)
x=-2
Plug that in:
3(-2)+15
-6+15
JM=9
