Answer: $13.75
Step-by-step explanation: You first multiply 15 and 0.75 which is $11.25 and then you add the fee which is $2.50 which gives you $13.75.
But it's not one doesn't always have to be the gcf
<span>the answer:
the main condition can be found one of the following given methods:
if A = B*C*D, if we want to find the value of B, so B = A /C*D, the similar method can be applied to find the value of C an D. These are C= A/ B*D and D = A /C*B
in our case we have C = 2*Pi* R, if we want to find the value of Pi, it is Pi = C / 2*R
the true answer is D</span>
1. To estimate, lets round the dimensions to 14 feet and 12 feet. Then, we calculate the perimeter as usual.
(14 + 12)2 = 26 * 2 = 52 feet as an estimate.
2. We need to write 8 and 3 inches in feet, and to do that we divide by 12, giving us 2/3 and 1/4. So, the mixed numbers are 13 2/3 feet and 12 1/4 feet. Each fraction represents the inches.
3. Using the fractions, we can find the perimeter.
(13 2/3 + 12 1/4)2 = 25 11/12 * 2 = 51 10/12 = 51 5/6 feet.
4. Our result from part 3 is pretty close to our estimate from part 1 - just 1/6 feet, or 2 inches off.
5. Now, we can just subtract the width of the doorway from our perimeter.
51 5/6 - 2 1/4 = 49 7/12 feet.
6. Finally, we divide our new perimeter by 8, and then round up.
49 7/12 / 8 ≈ 7 boards.
