Answer:

The speed is 160 km /h

Step-by-step explanation:

A driver spent 45minutes to cover a distance of 120km

Convert minutes to hour

45 min = 45 /60 hr = 3/4 hr

Use the distance equation

d = ts

Find the speed

s = d/t

Substitute the distance and time value and find the value of speed

s = 120 / (3/4) = 120 * 4/3 = 160 km /h

4/3⋅92−29=A cylindrical-shaped water tank has a diameter of 4 feet and is 12 feet tall. Which is closest to the volume of this t

Nookie1986 [14]

Answer:

Actual volume: 150.8

Step-by-step explanation:

the equation to find the volume of a cylinder is:

V= pi (r)^2 (h)

r= radius

h= height

To get the radius, you divide the diameter by 2.

when you plug in the numbers is looks like this:

V= pi (2)^2 (12)

you'll get 150.8 ft^3

I'm not really sure which volume would be the closest, but it should be around the answer I provided

Tell wheter x and y show direct variation. Explain your reasoning. x = 5/8y

inessss [21]

X varies directly as y would be
$x= y(\frac{5}{8} )$

x vairies inversly as y would be
$x= y(\frac{5}{8y} )$

not sure if the y is on the bottom or on top from looking at the question
