Exponents: 2 (if 3y is being squared)
Answer:
The 8th graders sold 180 more tickets
I counted 72 letters and 17 words so...
72/17 = 4.23 to the nearest whole number: 4 letters per word
Answer:
3x - 3y + 15
Step-by-step explanation:
Multiply everything inside the parenthesis by the outside number.
3 times X gives us 3x
3 times -Y gives us -3y
3 times 5 gives us 15
Answer:
63.59
Step-by-step explanation:
If the perimeter is 32.13, that means it is equal to
2r + 2πr/4 = 32.13
Solving this for r we get 9
Now, we can find the area, which is 3.14*r^2 / 4. Assuming pi to be 3.14 again, we get 63.585. Rounding this to the nearest hundredth, we get 63.59
