Answer:
C. 1/4 lb of chicken per person
Step-by-step explanation:
Find the rate of change for the situation.
A chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken for 68 people.
A. 9/17lb per person
B. 4 lb per person
C. 1/4 lb per person
D. 36 people
Solution
9 lbs of chicken for 36 people
Chicken per person = Total lbs of chicken / Total number of people
= 9 lbs / 36 people
Chicken per person = 1/4 lb of chicken per person
17 lbs of chicken for 68 people
Chicken per person = Total lbs of chicken / Total number of people
= 17 lbs / 68 people
= 1/4 lb of chicken
Chicken per person = 1/4 lb of chicken per person
Therefore, the rate of change of the situation = 1/4 lb of chicken per person
Answer:
(i)
time to bounce in one direction is 0.75 sec
(ii)
time to bounce in other direction is 1.5 sec
(iii)
total time is 2.25 sec
Step-by-step explanation:
Time to bounce in one direction:
we can see that height is increasing till t=0.75sec
so, time to bounce in one direction is 0.75 sec
Time to bound in other direction:
we can see that height is decreasing from t=0.75 to 2=2.25 sec
so, time to bounce in other direction is 2.25-0.75
=1.5 sec
Total time :
We know that
total time = (time to bounce in one direction)+(time to bounce in other direction)
now, we can plug values
total time =0.75+1.5=2.25 sec
