Answer:

Cylinder on the left has 2 times the volume

Step-by-step explanation:

Volume of the cylinder on the left

V = pi * r^2 h

The radius is 1/2 the diameter, so

r = 2x/2 = x

r =x and h  =x

Substituting in

V = pi * x^2 *x

V = pi x^3

Volume of the cylinder on the right

V = pi * r^2 h

The radius is 1/2 the diameter, so

r =x/2 and h  =2x

Substituting in

V = pi * (x/2)^2 *2x

V = pi x^2/4 *2x

V= pi x^3 *1/2

V = 1/2 pi x^3

The volume of the cylinder on the right is 1/2 the volume of the cylinder on the left.

Cylinder on the left has 2 times the volume

What is the slope of the graph of 8x – 4y = 11?
AlekseyPX
Y = mx + b
where m is the gradient (slope)
-4y = 11 - 8x
4y = 8x - 11
y = 2x - 11/4

Two skaters are practicing at the same time on the same rink. A coordinate grid is superimposed on the ice. One skater follows t
myrzilka [38]

Answer:

The skaters will collide at the points;

(2,28) and (4,24)

Step-by-step explanation:

The points they might collide will be the points when both y are equal;

-2x + 32 = -2x^2 + 18x

2x^2 -18x -2x + 32 = 0

2x^2 -20x + 32 = 0

2x^2 - 16x - 4x + 32 = 0

2x(x -8) -4( x -8) = 0

(2x -4)(x -8) = 0

2x = 4 or x = 8

x = 4/2 or x = 8

hence; x = 2 or 8

Now let’s get the y value

at x = 2, just substitute into any of the 2

y = -2x + 32

y = -2(2) + 32

y = -4 + 32 = 28

at x = 4

y = -2(4) + 32

y = -8 + 32

y = 24

The points that they will collide are;

(2,28) and (4,24)

. Jordyn can swim 4/5 mile in 1/3 hour. How far can she swim in 1 hour?
Blizzard [7]

Answer:

2.4 miles

Step-by-step explanation:

This is a simple ratio problem.

Jordyn swims 4/5 mile in 1/3rd hour. So how many miles will they go in 1 hour? Let that be x:

That is 12/5 miles or 2  2/5 miles

In decimal, that's 2.4 miles
