Answer:
L= 86 yards
Step-by-step explanation:
Perimeter = 2length + 2width
So,
302= 65(2) + 2(L)
302= 130+2L
-130
172=2L
Length= 86
X= y(d-b) over a-c would be the answer

Answer: B. 9
Step-by-step explanation:
First, find the median of the data set. This set has an even number of points, so find the average between the two middle points: 18 and 19. 18+19 = 37. 37/2 = 18.5. <em>The median is 18.5.</em>
Now, to find the lower quartile, find the median of the lower half of the data set {11, 12, 14, 15, 18}. The number in the middle is 14. <em>The lower quartile is 14.</em>
To find the upper quartile, find the median of the upper half of the data set {19, 21, 23, 25, 55}. The number in the middle is 23. <em>The upper quartile is 23.</em>
To find the interquartile range, subtract the lower quartile from the upper quartile. 23-14 = 9. <em>The interquartile range is 9.</em>
V =

where r is radius and h is height
so when radius is (x+8) and height is (2x+3),
volume =
