Answer:
72
Step-by-step explanation:
C = pi* d
pi= 3 (given in the problem)
d=24(the diameter is given in the picture)
C= 3*24 = 72
Hey there! I'm happy to help!
First let's plug y into the first fraction.
![\frac{12-3(3)}{2} =\frac{12-9}{2}=\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B12-3%283%29%7D%7B2%7D%20%3D%5Cfrac%7B12-9%7D%7B2%7D%3D%5Cfrac%7B3%7D%7B2%7D)
Now we do the second fraction.
![\frac{2(3)-4}{3}=\frac{6-4}{3}=\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%283%29-4%7D%7B3%7D%3D%5Cfrac%7B6-4%7D%7B3%7D%3D%5Cfrac%7B2%7D%7B3%7D)
We also need to multiply the second fraction by 3 as it is multiplied by y.
![3(\frac{2}{3})=2](https://tex.z-dn.net/?f=3%28%5Cfrac%7B2%7D%7B3%7D%29%3D2)
Now we add 2 and 3/2, giving us 7/2.
Have a wonderful day! :D
Answer:
166. 5
Step-by-step explanation:
Given the following :
Mean weight (m) = 142 lbs
Standard deviation (sd) = 14 lbs
Renne = 96 percentile, what is Renne's weight
Using the equation :
Zscore = (score - mean) / standard deviation
96 percentile = 0.96 is equivalent to a Zscore of
1.75
Hence,
1.75 = (score - 142) / 14
14 * 1.75 = score - 142
24.5 = score - 142
24.5 + 142 = score
Score = 166.5

Step-by-step explanation:
Culvert is a tunnel, therefore we can use the volume and area formula of a cylinder.
Circumference is given such as 280 cm and the circumference formula of a circle is C = 2*pi*r
Solving for the radius, we have:
280 = 2*3.14*r
r = 280/2*3.14
r = 44.59 cm
Area of one end:
Area = pi*r²
Area = 3.14 * 44.59²
Area= 6,243.2 cm²
The total area is times two of area since there were two ends in the culvert.
Total area = 6243.2 * 2
Total area = 12,486.32 cm²
