It is 18/20 and in simplest form it is 9/10.
Steps:
1.You have to add all the shirts, 2+7+11. This is 20, this will become your denominator
2. See what portion is NOT BLACK, the non black at 7 and 11, once you add these it becomes 18. 18 is now your numerator.
3. You now have the fraction 18/20 which you can simplify into 9/10
Hope this helps :)
Answer:
57/76% = Y/100%
76Y = 57 x 100
76Y = 5700
Y = 5700/76 = 75
Step-by-step explanation:
so the number is 75
have a beautiful day ahead
Answer:
The answer is option A.
Step-by-step explanation:
If the report is made once a month, the daily variations (including the tendency to decrease efficiency on Friday) will be masked within the monthly result.
It would only generate an ethical problem in the case that Fridays fall in different samples, but in the case of the monthly report there are usually 4 or 5 Fridays included in each sample.
14/15*100
14/3*20
14/1*6.66
14*6.66
93.24
The angle < pi/2 and whose sine is 1/2 is pi/6
so let 4x = pi/6 and we have x = pi/24 which is one solution.
angle in second quadrant = 5pi / 6 so x = 5pi/24 is another solution.
Each of these will give new angles as we revolve around the circle in steps of pi/2 so for x = pi/24 next one will be 13pi/24 and for x = 5pi/24 next one will be 17pi/24 This will be true for all angles less than 48pi/24 (ie 2pi)
so there will be 8 solutions
