Answer: The volume of cylinder Q is 12 times the volume of Cylinder P.

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

If cylinder Q has radius, r and height, h,

Then

Volume of cylinder Q = πr²h

For cylinder P,

Height = 3h

Radius = 2r

Volume of cylinder P = π(2r)² × 3h

= 4πr²× 3h = 12πr²h

Therefore, the ratio of the volume of cylinder P to the volume of cylinder Q is

12πr²h/πr²h = 12

A bag of potatoes weights 30 lb. If 74% of a potato is water, how many pounds of water are there in the bag?
Nadya [2.5K]

Answer: There are 22.2 pounds of water in the bag.

Step-by-step explanation:

Hi, to answer this question we simply have to multiply the total weight of the bag by the water percentage in decimal form (divided by 100).

Mathematically speaking:

30 x (74/100) = 30 x 0.74 =22.2 pounds

There are 22.2 pounds of water in the bag.

Feel free to ask for more if needed or if you did not understand something.

1. Find the equation of a line, in point-slope form, that passes through the points (2,3) and (5,7).
Ket [755]
Slope = (7-3)/(5-2) = 4/3

<span>passes through the points (2,3) and (5,7).
so
y = mx + b
3 = 4/3(2) + b
3 = 8/3 + b
b = 3 - 8/3
b = 9/3 - 8/3
b = 1/3

equation
y = 4/3x + 1/3</span>

What else would need to be congruent to show that triangle ABC and triangle XYZ is congruent by AAS
julia-pushkina [17]

Answer:

C. ∠B ≅ ∠Y

Step-by-step explanation:

This is because AAS means 2 angles and 1 side are congruent.

Which means there are two possible answers: B or C. But answer B says angle C and Z are congruent which would make both triangles congruent by ASA and not AAS
