Answer:
195
Step-by-step explanation:
½(B¹ + B²) h is the formula for a trapezoid so you would do
1/2(10+16)15 which gives you 195

2
Answer:
13 inches
Step-by-step explanation:
Use the Pythagorean Theorem:
a^2 + b^2 = c^2
(5)^2 + (12)^2 = c^2
c^2 = 169 in^2
c = 13 inches
Answer:
6 is most directly associated with the flow rate of customers
Step-by-step explanation:
Reason:
0.25 is the number of customers in the gift shop at a given point of time is WIP inventory
7.5 is the average time spent by customer in the shop and it is the throughput time.
Flow rate = WIP inventory/Throughput time
=0.25/7.5
= 0.0333 per minute = 2 per hour or 6 per 3 hour as given in question.
