Answer: 21 hours
Step-by-step explanation:
The lawn order can produce 10 landmowers in 7 hours.
This means that their speed is:
= 10/7
= 10/7 landmowers per hour
If they want to produce 30 lawnmowers, the amount of time they will take is:
= 30 ÷ 10/7 per hour
= 21 hours
I think it'd be 1/16 of the band because you'd multipy 1/4 by 1/4
I’m not sure but the answer might be 115
Answer:
Step-by-step explanation:
28. Area of the circle = π where r is the radius of the circle.
Given diameter = 14m, therefore radius = = 7m
Now area of the circle = 49 or = 49 * 3.14 * 3.14 = 483.12
29. Volume of cylinder = πh = π* * 3 = 6.75π cu. feet or 21.195 cu. feet
30. A ball resembles a sphere. Volume of the sphere =
Given diameter = 30inches; Therefore, radius = 15 inches
Now, Volume of the ball = = 4500π cu. inches or 14310 cu.inches
All you need to find is : 7 × ? = 154
so you need to divide :
154 ÷ 7 = 22
so the length of the box is 22 inches
hope this helps : )
