Answer:

452.16 m³

Step-by-step explanation:

d = 3h = 3×4m = 12 m

r = d/2 = 12m/2 = 6 m

V = Ab×h = π·r²·h

= 3.14×36m²×4m

= 452.16 m³

A train ticket in a certain city is $2.00. People who use the train also have the option of purchasing a frequent rider pass for
DENIUS [597]

Answer:

the number of times in a month the train must be used, so that the total monthly cost without the pass is the same as the total monthly cost with the pass, is b. 24 times

Step-by-step explanation:

in normal purchase, train ticket (A) = $2.00

using frequent pass,

frequent pass (P) = $18

train ticket using frequent pass (B) = $1.25

Now, let assume the number of times in a month the train must be used = M

so,

                                  A x M = P + (B x M)

                            $2.00 x M = $18 + ($1.25 x M)

    ($2.00 x M) - ($1.25 x M) = $18

             M x ($2.00 - $1.25) = $18

                                        M = $18 : $0.75

                                        M = 24

Thus, the number of times in a month the train must be used is 24 times

Does (2, 8) make the equation y = 4x true?
guajiro [1.7K]

Answer:

Yes, it does.

Step-by-step explanation:

The equation y = 4x is the same as saying:

"The y coordinate is 4 times as much as the x coordinate"

So, with the coordinate set of (2, 8):

y = 4x

8 = 4 * 2

This is correct, meaning the coordinate does fit the equation.

Hope this helps!

A cube with edges that measure 10 centimeters has a volume that is twice as much as a cube with sides that measure 5 centimeters
rodikova [14]

Answer:

False

Step-by-step explanation:

We find the volumes of the two cubes and compare them.

volume of cube = side^3

The volume of the 10-cm cube is:

V = (10 cm)^3 = 1000 cm^3

The volume of the 5-cm cube is:

V = (5 cm)^3 = 125 cm^3

1000/125 = 8

The volume of the 10-cm cube is 8 times the volume of the 5-cm cube.

The statement is false.
