Answer:
Solving for 
we got 
and replacing this we got:
And then the best option for this case would be:
b.csc x
Step-by-step explanation:
For this case we have the following expression given:
We know from math properties that the definition for cot is
If we use this definition we got:
Now we can use the following identity:
Solving for we got and replacing this we got:
And then the best option for this case would be:
b.csc x
Answer:
The answer would be B.
Because if you multiply all the numbers of ABC then go through the list of the A'B'C' options only B matches up
Answer: 3 (
x
+
7
)
Step-by-step explanation:
The question is looking for the amount of boxes (24 per box) needed for the event (300). If you multiply 24 by each number, you would be able to find the answer. 24*11 = 264, so that isn’t enough. 24*12 = 288, and that also isn’t enough. But if you do 24*13, you get 312, which gives you more than enough cupcakes for the event. So the answer is 13.
