-3(2x+1) > -2(x+6)

-6x -3 > -2x - 12

-6x -3+6x > -2x - 12+6x

-3>4x-12

-3+12>4x-12+12

9 > 4x

4x<9

x<4/9

(-∞, 4/9)

Angle m AOC=108° m AOB=3x+4° m BOC=8x-28°<br><br> Find m AOB

Alex787 [66]

Hello from MrBillDoesMath!

Answer:

Discussion:

A diagram is always appreciated!

Assuming that

mAOC = mAOB + mBOC =>

108 = (3x + 4) + (8x - 28) => combine common terms

108 = (3x + 8x) + (4 - 28 ) =>

108 = 11x - 24 => add 24 to both sides

132 = 11x =>

x = 132/11 = 12

So mAOB = 3x + 4 = 3(12) + 4 = 36 + 4 = 40

Thank you,

MrB

Find the volume of the cone.

8_murik_8 [283]

Answer:

$V=471\ \text{units}^3$

Step-by-step explanation:

Given that,

Radius of the cone, r = 5 units

Height of the cone, h = 6 units

We need to find the volume of the cone. The formula for the volume of the cone is given by :

$V=\pi r^2 h$

Substitute all the values,

$V=3.14\times 5^2\times 6\\\\V=471\ \text{units}^3$

So, the volume of the cone is $471\ \text{units}^3$ .
