Step-by-step explanation:
20 men work 8 hours a day for 18 days.
that are
20×8×18 = 2880 work hours to complete that work.
if 24 men work 5 hours a day, that are
24×5 = 120 work hours per day.
we still need to do the total 2880 work hours.
so, they will need
2880 / 120 = 24 days to complete the work.
Answer:
60.26yd³
Step-by-step explanation:
Since we are not given the diagram, let us assume that;
Length of the base = 5.4yd
Height of the pyramid = 6.2yd
volume of the square pyramid = BH/3
B is the base area = L^2
B = 5.4²
B = 29.16yd²
H = 6.2yd
Get the volume
volume of the square pyramid = 29.16*6.2/3
volume of the square pyramid = 180.792/3
volume of the square pyramid = 60.26yd³
Hence the volume of the square pyramid to nearest hundredth is 60.26yd³
Answer:
x (40-10) -12000≥980
The factory must sell 433 backpacks to meet its weekly goal.
Hi, to answer this question we have to write an inequality.
So, since the backpacks (x) are sold by $40 and the cost of making one is $10, the revenue per bag is equal to 40x and the cost is 10x.
12,000 of operating expenses are also expenses.
So, for the profit:
Profit = revenue- cost
P = 40x-10x-12,000
P = x (40-10)-12000
The factory goal is to make a profit of at least $980 each week, so, the profit must be greater or equal than 980.
x (40-10) -12000≥980
Solving for x
30x-12000≥980
30x≥980+12000
30x ≥12980
x≥12980/30
x≥432.6
x≥433 (rounded, because if the sell 432 they will not meet the goal)
The factory must sell 433 backpacks to meet its weekly goal.
