Let x be the number, then 60 = 40% of x & x =60/40%=60/0.4=150
then the number of which 60 represent 40% of it is 150
2) Let x be the time needed to the 16 clerks to finish the job
In one day the 32 clerks complete a portion of 32/22 of the job
In one day the 16 clerks complete a portion of 16/x of the job
So in 1 day===> 32/22 =16/x ==> x=(22*16)/32 = 11 days
Answer:
![\frac{1}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B18%7D)
Step-by-step explanation:
Slope of ramp = ![\frac{vertical change}{horizontal change}](https://tex.z-dn.net/?f=%5Cfrac%7Bvertical%20change%7D%7Bhorizontal%20change%7D)
= ![\frac{21}{378}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B378%7D)
= ![\frac{1}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B18%7D)
The selling price is
Cost+markup
1,260.45+396
=1,656.45
We can use the points (-4, 3) and (3, 1) to solve.
Slope formula: y2-y1/x2-x1
1-3/3-(-4)
-2/7
Therefore, the answer is C
Best of Luck!
To get perimeter, you simply add all the side lengths. So we will ad 23.2 + 23.2 + 12 + 12 = 70.4
The perimeter is 70.4 m
