If 4x-3=13, then 4x=16

Answers

true (you split it down the middle and then make it so 4x are the only variables on the left side)

Answer:

True!

Step-by-step explanation:

4x - 3 = 13

Add 3 to both sides;

4x = 16

Divide both sides by 4;

x = 4

A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone is equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r?

Answers

Given:
Let us assume the radius of the cylinder is x.
radius of the cone is half the radius of the cylinder: x/2
height of the cone is equal to the radius of the cylinder: x

radius of cone: x/2 ; height of the cone: x

volume of the the cone = π r² h/3
V = 3.14 * (x/2)² * x/3
V = 3.14 * x²/4 * x/3
V = (3.14 * x² * x)/4*3
V = 3.14 x³ / 12

Answer:

(1/12) Pi r^3 option C on plato

Step-by-step explanation:

r = radius of the cylinder

V = (1/3)Pi c^2 h for a cone.

and c = r/2 and h = u

so Volume of the cone is (1/12) Pi r^3

A gourment shop wants to mix coffe beans that cost $3.00 per pound with coffe beans that cost $4.25 per pound to create 25 pounds of a new blend that cost $3.50 per pound. Find the number of pounds of each nerded to produce the new blend

Answers

If the gourmet shopkeeper mix 15 pounds of coffee beans which costs 3.0$ per pound with 10 pounds of coffee beans costing 4.25$ per pound.
The mixture of 25 pounds will cost 3.5$ per pound.

It can be found using
3*x + 4.25*(25 -x) = 25*3.50
