96 is the correct answer to your question i
I hope this isn't too late! You can find the answer to this by first finding the area of the circle, A=πr². So since the radius is 10, we input that into the equation to get π100. Now, there is 360° in a circle and a sector of 90° is 1/4 of it. So to answer the question all you have to do is find 1/4 of the area of the circle.
The answer is π25.
To solve the other questions on your assignment just think about how much the sector is of the full 360° of the circle, for example 180° is 1/2 of the circle or 270° is 3/4 of the circle, and multiply the fraction by the area of the circle.
Hope this helped, good luck! :)
12 is the 4th term? Dont quote me on that though. I am 90% sure.
Answer: f(g(x)) = x - 2
<u>Step-by-step explanation:</u>
f(x) = x + 2
g(x) = x - 4
f(g(x)) = f(x - 4) = (x - 4) + 2 <em>replaced x with x - 4</em>
= x - 2 <em>simplified</em>
You can set up this equation as:
Because remember, 70% is equal to 0.7 and x represents the unknown value. So, let's just solve it:
So,
70% of 120 is 84.
