a car travels an average speed of 64 miles per hour. how many miles does it travel in 5 hours and 15 minutes?
Contact [7]
Distance is speed or velocity multiplied by time: d = v * t

We know the speed of the car and the time it travelled, so input the two into the equation above and solve for the distance travelled.

d = v * t

d = 64 m/h * (5 hours and 15 minutes) = 64 m/h * (5.25 hours)

d = (64 * 5.25) miles


d = 336 miles

NISA [10]

Answer:

B.It takes more than 12 loads to wash 9 bins of towels.

Step-by-step explanation:

The function f(x) gives the number of loads required when there are x bins of towels to be washed.

f(x)=Number of loads

x=Bins of towels

Therefore in the inequality f(9)>12

  • Number of loads=12
  • Bins of towel =9

If f(9)>12, it means Number of loads is more than 12.

f(9)>12 therefore tells us that it takes more than 12 loads to wash 9 bins of towels.

The correct option is B

The square root of 3 is 1.7320508075688772, this number cannot be written as a fraction so it is irrational.

-7/3 is rational because it is already in fraction form.

What shape is the cross section formed by the intersection of a cone and a plane parallel to the base of the cone?
Ksju [112]
<h2>Answer:</h2>

A circle

<h2>Step-by-step explanation:</h2>

The representation of this problem is shown below. The cross-section is the name for a slice that cuts through a solid. If we move around the height of the cone through its volume, we will find that at every point the cross section will be a circle. The radius of that circle will depend on the point we are on. On the base of the cone, the circle will have the same radius of the cone and the radius will be decreasing when moving until we get to the apex.
