Step-by-step explanation:
1/2s+38=1642
0.5s=1642-38
s=1604/0.5
s=3208
Answer:

Step-by-step explanation:
Given

Solve
Using sine rule, we have:

This gives:

So, we have:

In radical forms, we have:


Take LCM

Rewrite as:

Hence:

Rate is an expression for a change of some unit per unit of time. For this problem, we find the rate of change of the price by a simple equation which is expressed as:
Rate = change in price / change in time
Rate = ($1.20/lb - $0.90/lb) / 5 yrs - 0
Rate = $0.06 per lb per year
Thus, the answer is B.
Answer:
A
Step-by-step explanation:
4×π×7.2^2
207.36π
651.44065264838 since it is a bowl and not a sphere you divide it by two and get 325.72
