Step-by-step explanation:
6x-7
= 6×2-7
=12-7
=5
b) 3x
=3×2
=6
If you put 4 over 20 and did a ratio to x over 100 it would be 20%
Answer: if i did this correctly its {x,y} = {3,6}
Step-by-step explanation:
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! :)
