Answer:
V = 15 pi ft^3
Step-by-step explanation:
The volume of a cone is given by the formula
V=1/3 pi r^2 h
We know the radius and the height
V = 1/3 pi *(3)^2*5
V = 1/3 *pi*9*5
V = 15 * pi
Leave in terms of pi
V = 15 pi ft^3
Well, he could of spent $24
And we know he spent $4 on the magazine So subtract $4 from $24 to get $20
And $20/5(the composition books) = $4
So the Composition books also costed $4
Is this what you're looking for?

Answer: 8.2 (choice B)</h3>
==========================================================
Explanation:
First we'll need the length of segment BD, which I'll call x for now. The similar triangles allow us to set up the proportion below to solve for x
AD/BD = BD/DC
13/x = x/4
13*4 = x^2
52 = x^2
x^2 = 52
x = sqrt(52)
Segment BD is exactly sqrt(52) units long.
------------
Now focus your attention on triangle BDC. We'll use the pythagorean theorem to find BC
(BD)^2 + (DC)^2 = (BC)^2
( sqrt(52) )^2 + ( 4 )^2 = ( m )^2
52 + 16 = m^2
68 = m^2
m^2 = 68
m = sqrt(68)
m = 8.2462 approximately
m = 8.2
Answer:
PT= 130
Step-by-step explanation:
Since T is the midpoint of segment PQ,
PT = TQ
7x - 24 = 6x-2
Subtract 6x both sides and add 24 both sides
7x -6x - 24 = 6x -6x -2
x - 24 + 24 = -2 + 24
x= 22
Substitue x into PT
7(22) - 24
154 - 24
PT= 130
Answer:
slope intercept form is y=-2/3x+5
