If Reducing 2 men will bbe enough too finish the work in 10 days
For rate of work use the formualar
rate of work = quantity of work / duration
10 men can do the work at a rate of = 1 / 8
x men can do same work at a rate of = 1 / 10
x * ( 1 / 8 ) = 10 * ( 1 / 10 )
x = 1 * 8 = 8
therefore 8 men can do the work in 10 days
number of men reduced = 10 men - 8 men = 2 men
Hope it helped
Answer:
$12,000
Step-by-step explanation:
20% as a decimal is 0.20
30,000 x 0.20 = 6,000
If the employer matches that, the amount deposited is double.
6,000 x 2 = 12,000
That is probably the answer they want. Technically the question asks way *you* will have contributed, which is $6,000, but I don’t think they’re trying to make this a trick question. I would go with 12k
You must score a minimum of 190 in the fourth test to get an A for the course
The first three tests are worth 100 points while the fourth is worth 200 points
The 1st score = 84
The 2nd score = 92
The third score = 89
Let the fourth score on a 200 scale = x
The fourth score on a 100 scale = x/2 = 0.5x
Average = (1st score + second score + third score + 4th score) / 4
Average = (84 + 92 + 89 + 0.5x) / 4
To get an A:
Average ≥ 90
(84 + 92 + 89 + 0.5x) / 4 ≥ 90
265 + 0.5x ≥ 360
0.5x ≥ 360 - 265
0.5x ≥ 95
x ≥ 95/0.5
x ≥ 190
You must score a minimum of 190 in the fourth test to get an A for the course
