Answer:
Step-by-step explanation:
p and h are number of plumbers and helpers, respectively.
Twenty workers earn a total of $2600
p+h = 20
h = 20-p
160p + 100h = 2600
160p + 100(20-p) = 2600
60p = 600
p = 10
h = 20-p = 10
Ten plumbers and ten helpers.
Answer:
B
Step-by-step explanation:
Answer:
We get value p=16
Step-by-step explanation:
When triangles are similar, the ratio of corresponding sides is equal.
In the given triangles we have to find value of p
We have the ratio: (Can use ratio of any two sides)
Now, putting values and finding p
So, we get value p=16
2t + 8 ≥ -4(t+1)
PEMDAS
2t + 8 ≥ -4t - 4
2t + 12 ≥ -4t
12 ≥ -6t
-2 ≤ t
Macro can finish the puzzle in 3 hours. We can say that her speed for working is 1/3 or 1/3 puzzle per hour.
Now if they work together, this turns into 1 puzzle per hour.
That must mean that Cliff would be doing the other 2/3 of the puzzle while Macro does his 1/3 in that hour. If Cliff has a speed of doing them 2/3 per hour. Then it would take 1 and a half hour to finish 1 whole puzzle.
