Answer:

(86-75)= 11

now 11/75=0.147

hence 0.147 x 100= 14.7%.

therefore the percentage of workers needed to produce 86 cases is 14.7%

Step-by-step explanation:

step 1: We subtract the averages.

step 2: we devide the result in step one by the old average.

step 3: we multiply the result in step 2 by 100%.

Someone please! Check the answer twice! I just want one wrong and that’s it please! NO FILES I SWEAR IF SOMEONE ADDS A FILE THEI
MakcuM [25]

Answer:

x = 55, because if you look the whole entire bar is 180° in total but you dont have to worry about that because that's not what the question is wanting you to look at, If you look really close there is a half and half on both sides so that means there is a 90° angle so you would have to take 90-35 and that is what gives you your missing angle which is 55.

Which graph shows the information in the table? PLZ HELP I GIVE BRAINLIEST IM TIMED!!!!
sleet_krkn [62]

Answer:

A

Step-by-step explanation:

I think that's the answer because

60 minutes = 1 hr

120 minutes = 2hrs

So the graph must be constant with the write amount of min/hr since the x axis is the number of mins and the y axis is the number of hours.  (x,y)

(60,1)

(120,2)

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 50 pounds each, and the small boxes
skad [1K]
So this is how we are going to solve for the given problem above.
Given that x = number of large boxes
and 120-x = number of small boxes.
So here is the solution:
50x + (120-x)20 = 4050
50x + 2400 - 20x = 4050
30x + 2400 = 4050
30x = 4050 - 2400
30x = 1650 <<divide both sides by 30
x = 55.
Therefore, there are 55 large boxes
120 - x = small boxes
120 - 55 = 65 small boxes.
Hope this is the answer that you are looking for.
Let me know if you need more help next time!
