I don’t know the answer to this question
Answer:
A.Both of the students did the problem correctly.
Step-by-step explanation:
B. Nikki multiplied the fraction(8/3) to the items in the parentheses. Then multiplied each side with 3. Jon did the opposite. He first removed the fraction by multiplying each side by 3. Then he multiplied 2 to the items in the paranthesis.
C. I prefer Jon's method. Fractions can be tricky. I prefer to remove them as soon as possible. This time the items in the paranthesis had whole numbers. But had any of them been a fraction too, the problem would have gotten a lot more tricky and it would very easy to make a mistake or miscalculate something.
Answer:
≈ 39.3 in²
Step-by-step explanation:
The area of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 10² × 
=
≈ 39.3 in² ( to 1 dec. place )
Answer:
Answer is y = 2x - 3
