Fill in the table to convert the units of time from hours to minutes or minutes to hours.
tester [92]
Ok so first we need to under stand that 60 minutes is equivalent to 1 hour, by knowing this we should be able to answer the following. Our first box which needs to be filled in asking how many hours are in 300 minutes, well let’s figure this out. So we know that in 60 minutes it will be equivalent to one hours, so in order to find how many minutes are in 300 minutes we would divide 300 by 60 which give a us 5. Therefore causing the second box to me 5 hours. Our next and final box is asking how many hours are in four minutes well this one is a little harder than our previous one but I’ll help you through it. By following the same procedure as we did the previous question we are going to divide 4 by 60 and we know that dividing like so we are going to get a decimal but that’s ok it’s going to give us the answer we need to fill in the box. By dividing like so we should get a long decimal that look that this 0.066666666666667. I am going to simply this down to 0.0667. Causing my last box to be 0.667.
Summary:
second box: 5 hours
Third box: 0.0667 hours
Hope this helps!!!

A pop can shown on the right has a diameter of 2.5 inches and a height of 5 inches. If necessary, round your answers to the near
Rashid [163]

Answer:

a) The can can hold 24.54 inches³ of pop

b) There will be 22.09 inches³ of pop in the can

c) The cone can hold 7.36 inches³ of pop

Step-by-step explanation:

a) We need to work out the volume of the can, using this equation: volume of a cylinder = πr²h

  • The diameter is half the radius: r = 1.25 inches
  • r² = 1.5625
  • π × 1.5625 × 5 = 24.54369... ≈ 24.54 inches³

b) We will still work out the volume of the can, but the height is 4.5 inches instead of 5 inches:

  • r² = 1.5625
  • π × 1.5625 × 4.5 = 22.0893233... ≈ 22.09 inches³

c) The cone will have a height of 4.5 inches and a diameter of 5 inches; the volume of a cone = 1/3(πr²h)

  • 1/3(π × 1.5625² × 4.5) = 7.3631077... ≈ 7.36 inches³

Hope this helps!
