Answer:
9 boards
Step-by-step explanation:
2/3 of the porch= 6 boards
so to figure out how much one third of the porch needs you find half of what it takes to fill in 2/3 of the porch and you get 3.
so 3=1/3 of the porch
then you simply do 3times 3 or 3+3+3 and you get 9
so it takes 9 boards to fill the whole porch
Answer:
850
Step-by-step explanation:
To get my answer, I divided 150 by 17. (The survey of people and the # of them under 21) I got 8.8235. Next, I divided 7500 (the total of people in the stadium) by 8.8235 (the decimal that I got above) I got 850.
To check my answer, I divided 7500 by 850 and got 8.8235, the same ratio as the survey.

Answer:
Your answer is C, 10.7cm
Step-by-step explanation:
The two flat sides of the figure are 3 cm, so that part of the perimeter = 6cm
3cm is the radius of what would be a whole circle. We'll calculate the circumference, then divide by 4.
Circumference = (2)(pi)(r)
C = (2)(3.14)(3)
C = 18.84
18.84/4 = 4.71
Add 4.71 to the 6 cm above, = 10.71
