Answer:
B= 
Step-by-step explanation:
If you noticed, A= 
BH is the formula for finding the area for a triangle. Your goal is to get B by it's self. Your first step will be to clear of the fraction first, so you will multiply both sides by 2. 2(A)=2(BH). On the left, you have 2×A= On the right side, you have 2(BH), but since you have a number in the equation, you will only use 2×. To solve 2×, you will cnacel out both 2's and you have 1. 1×BH will still equal BH, so you are now left will B×H.
(Your new equation looks like this by the way). 2A=BH
Since you need to get B by its self, the way to clear the H away from the B is by dividing. You will now divide the B and H aswell as 2A and H. (It will look like this) 
. (Again when you have the same number or letter, you cross it out. When you divide, you won't change anything on the left side, and all you have to do on the right id to cross out the H next to the B and cross out the H on the bottom of the equation). You should be left with = B. Now you can turn it around for your final answer. B= .

Answer:
Part 1: Option C ( Allocative Efficiency)
Part 2 : Option D ( Voluntary Exchange)
Step-by-step explanation:
Part 1:
In Part 1 the school has sold all the vaccines at the given price and they will earn at least some thing form the vaccines sold. So this lies in allocative efficiency.
According to definition allocative efficiency is the efficiency every good or service is produced up to the point where the last unit provides a marginal benefit to consumers equal to the marginal cost of producing.
So the answer for the first part is part C
Part 2:
In second part the school has decided to give free medicines to people suffering from Asthma and Flu. So this lies in Voluntary exchange.
According to definition Voluntary exchange is providing of the goods free of cost to the consumers.
So school is providing free of cost vaccines to the students which is voluntary exchange and it is option D
solution:
solid spindle ab:
c= 1/2ds = ½(1.5) = 0.75in.
j= π/2c1= π/2(0.75)2 = 0.49701 in4
jmax = Tc/j
tab=jtal/c = (0.49701)(12)/0.75 = 7.952
sleeve cd = c2 = 1/2d2 = ½(3.0) = 1.5in
j = π/2(c24 – c14) = π/2(1.54-1.254) = 4.1172 in4
tab = jtl/c2 = (4.1172)(7)/1.5 = 19.213 kip.in
