Here, Twice fast means, she takes half time in doing same amount of work.
Let, Anna takes = 2t & Jane takes = t
It would be: 1/t + 1/2t = 1/15
2t + t / 2t² = 1/15
15(3t) = 2t²
2t² = 45t
Divide both sides by t,
2t = 45
t = 45/2
t = 22.5
& 2t = 22.5(2) = 45
In short, Anna would take 45 minutes
Hope this helps!
Answer:
(8,-2)
Explanation:
you reflect it over the x-axis
Answer:
B
Step-by-step explanation:
A. 8 * x = 80
8 * 5 = 40. 40 is not 80, so it doesn't work.
B. x + 4 = 9
5 + 4 = 9. This works.
C. 10 ÷ x = 5
10 ÷ 5 = 2. 5 is not 2, so it doesn't work.
D. x - 6 = 1
5 - 6 = -1. 1 is not -1, so it doesn't work.
Here, we are required bro determine how many worker Esther needs to employ to pick the same 600kg of onions in 3 hours as compared to 4 hours from last year.
This year, she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.
According to the data given, the total quantity of onions to be picked still remains 600 kg as from last year, only that she needs it done in 3 hours now.
Therefore,
- Since 24 workers finished the work in 4 hours,
- This means that 96 workers are needed to finish the work in 1 hour( from 24×4 = 96).
Therefore, since the work needs to be done in 3 hours this year, This means that it can be shared between X no. of workers.
Therefore, this year she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.
