The height of a cylinder is twice the radius of its base.
Ber [7]

Let x represent radius of circle.

We have been given that the height of a cylinder is twice the radius of its base. So height of cylinder would be 2x.

Now we will use volume of cylinder formula to our given problem.

V=\pi r^2h, where,

r = Radius of base of cylinder,

h = Height of cylinder.

Upon substituting our given values, we will get:

V=\pi\cdot x^2\cdot 2x

V=2x^3\pi

Therefore, our required volume expression would be 2x^3\pi.

A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second. 3 ft = 1 yd 5280 ft = 1 mi How much
just olya [345]
You'll need to convert both speeds into yards per minute.

12 mph = 12 mph     1760 yd    60 min
                ---------- * ------------ * ----------
                  1 mile       1 hr

Note that "miles" cancels.  So does "hours."  Finish this work.

Then convert   4.4 ft/sec into yards per minute.

Then, finally, compare your two rates via subtraction of the smaller from the larger.

Solve the system of equations using the substitution method.
Firdavs [7]

y = -1 + 3/8x

2x - 5y = 6

Substitute the first equation into the second equation, since y is already by itself.

2x - 5(-1 + 3/8x) = 6

2x + 5 - 15/8x = 6

2x - 15/8x = 1

16/8x - 15/8x = 1

1/8x = 1 Multiply 8 on both sides to get x by itself

x = 8


Plug x into either of the equations.

y = -1 + 3/8(8)

y = -1 + 3

y = 2


2(8) - 5y = 6

16 - 5y = 6

-5y = -10

y = 2

Answer:

y = 1/2x + 1

Step-by-step explanation:

Slope: 1/2

Point: (2,2)

y-intercept: 2 - (1/2)(2) = 2 - 1 = 1
