First, simplify the parenthesis. You’ll get:
1/4(4z)+7=-z+1

Then multiply 1/4 by 4z. You’ll get:
z+7=-z+1

Love like terms to the same side. I wanted to have the variable positive on time, so I moved variables to the left and constants to the right. You’ll get:
2z=-6

Divide both sides by 2. You’ll get :
z=-3

An oblique cylinder has a radius of 8 inches and a volume of 1,024 cubic inches. Use Cavalieri’s Principle to calculate the heig
enot [183]
Remark
All Cavaliere's principle says is that a slanted cylinder (for example) has the same volume as a cylinder with perpendicular parallel lines that the cylinder is sitting on.

I little known or maybe not a well emphasized fact is that the base is the same all the way up the cylinder. The coin picture below shows that. The basic formula for a Cavaliere cylinder is the same as for an ordinary cylinder.

See picture below

Formula
V = B * H 

Sub and Solve
V = 1024
r = 8
p=3.14

V = pi*r^2 * h
1024 = 3.14*8^2 * h    combine the right side.
1024 = 3.14*64 *h       
1024 = 200.96 * h       divide by 200.96
1024/200.96 = h
You are only getting 5 inches.

None of your answers work.The conversion to meters is going to give you an even smaller number. If you add a comment, I'll come back and edit this question.

Vaselesa [24]

Answer:

C. y<3

Step-by-step explanation:

We are required to determine the solution set of the inequality

15y-9

Step 1: Add 9 to both sides

15y-9+9

Step 2: Divide both sides by 15

15y \div 15

The solution set of the given inequality is: y<3.

The correct option is C.

1. Use formula provided

2. A = 3500 B = 2000 r = 4.75 n = 12months/4 = 3 months t = ?

3. Solve

3500=2000(1+4.75/3)^3t

3t=logbase(31/12)*1500

t=logbase(31/12)*1500 / 3

t ≅2.568
