Answer:
The height of the cylinder is 4x units.
Step-by-step explanation:
volume of a cylinder = nr^2h
n = 22/7
r = radius = x/2
Let illustrate with an example. If the diameter of a cylinder is 6 and the volume is 6^3 = 216. The radius = 6/2 = 3
n3^2 x h = 216
h = 216/9 = 24
so the height is 4 times the diameter
Area of the base = nr^2
1/2^2 x x = 1/4 pi x^2
Work problems are solved by first figuring out how much of the job they can do in each hour. Shawn can do 1/4 of the job in an hour and Ellie can do 1/6 of the job in an hour. 1/6+1/4=2/12+3/12=5/12. This means that they can do 5/12 of the job an hour. This means that together they can do the job in 2 2/5 hours. The foreman is obviously wrong because first of all Shawn can do it alone in 4 hours, so with Ellie he will do it faster, and second of all 2 2/5<5. Hope this helped!
Number of widgets needed to make one motor = 11
Number of motors made each day = 4
Number of widgets used per day :-
= 4 × 11
= 44 widgets
Number of widgets I need to order for the next five days of the upcoming week :-
= 44 × 5
= 220 widgets
Therefore , my team should order 220 widgets for the next week ( 5 working days ) .
Answer:
a. 496 girls
b. 110 boys
Step-by-step explanation:
a. 3:4 ------- divide 372 by 3 and you get 124 now multiply that by 4 and you get 496
b. 2:5 -------- divide 275 by 5 and you get 55 now multiply that by 2 and you get 110
Answer:
10 / 9
Step-by-step explanation:
Let's suppose the other fraction is x. We are given 3 / 5 * x = 2 / 3
We can divide by 3 / 5 on both sides, which is the same as multiplying 5 / 3 on both sides:
5 / 3 * 3 / 5 * x = 2 / 3 * 5 / 3
This simplifies to:
x = 10 / 9
