In this question, they gave you the system of equations. You just need to use the two of them.
We want to find the m or the number of the multiple-choice questions. So we need to turn our last equation in the form of 'm's by translating the 'f's into 'm's.


If we know the m form of f, we can convert the second equation and find the answer:

Plug in the m value of f:

Distribute the 5:

Subtract -75 from both sides:

Combine like terms:

Divide both sides by -2:

So, we learned that the number of the multiple-choice questions is 12.
Answer:
Step-by-step explanation:
for qn 14 use the SOH CAH TOA method
use cos for this so. cos 47 degree= x/13
solve for x.
Answer:
5,024 inches squared
Step-by-step explanation:
Since the area of a circle is pi r^2, we basically have to replace the r with 40, since it's the radius. Therefore when replaced, it would be pi(40)^2. This makes 1600pi. Pi is technically 3.14, so I multiplied 3.14 and 1600 to get 5,024 inches squared.
Answer:
A)
Step-by-step explanation:
The triangle TRS is isosceles (Angle T = Angle R)
Then sides TS = RS and both are shorter than TR
A) TR > TS True
B) TR < TS False (TR > TS)
C) TR < RS False (TR > RS)
D) RS < TS False (RS = TS)
