Answer: It will take 1.875 hours
Step-by-step explanation:
Given that time t required to do a job varies inversely as the number of people working.
we have it expressed as
t∝1/N
where t is time required to do a job
N is the number of people working.
Introducing our constant of proportionality, we have tht
t=k1/N
t=k/N
Now since it takes 5 hr for 3 cooks to prepare the food , K becomes
t=k/N
5=K/3
K=5X3=15
Given that there are 8 cooks, time required to prepare dinner will be
t=k/N
t=15/8
t=1.875 hours
In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.
therefore your answer is:
Area of trapezoid = 1/2(b1 +b2) h
Where b1 = 6 cm , b2 = 20 cm and h = 10 cm
A = 1/2(6 + 20)(10)
A = 1/2 (26) (10)
A = 130
Answer
A = 130 cm^2
Hope it helps.
