So we add all the amounts together:
250 + 310 + 275 + 195 = 1030
Then we divide by 4 to find the average.
1030/4 = 257.5
The answer is D: $257.50
Hope that helps!
Answer:
125 traffic cones
Step-by-step explanation:
In order to find the total number of meters, we can set up a proportion to find based on the ration of cm to m:
, where 'x' is the number of meters
cross-multiply: x = 25(50) or x = 1250 m
Since there is a cone every 10 m, we can divide the total number of meters by 10:
1250/10 = 125 cones
Answer:
![\frac{7}{8}\pi](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B8%7D%5Cpi)
Step-by-step explanation:
observe
||a–b+c|| = ||a+b+c||
(a-b+c)² = (a+b+c)²
(a+b+c)² – (a-b+c)² = 0
((a+b+c)+(a-b+c))((a+b+c)–(a-b+c)) = 0
(2a+2c)(2b) = 0
(a+c)b = 0
a•b + c•b = 0
||a||×||b||×cos(π/8) + ||c||×||b||×cos(θ) = 0
![\cos(\theta)=-\frac{||a||\times ||b|| \times \cos(\frac{\pi}{8})}{||c||\times ||b||}=-\cos(\frac{\pi}{8})\\ \theta=\frac{7}{8}\pi](https://tex.z-dn.net/?f=%5Ccos%28%5Ctheta%29%3D-%5Cfrac%7B%7C%7Ca%7C%7C%5Ctimes%20%7C%7Cb%7C%7C%20%5Ctimes%20%5Ccos%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29%7D%7B%7C%7Cc%7C%7C%5Ctimes%20%7C%7Cb%7C%7C%7D%3D-%5Ccos%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29%3C%2Fp%3E%3Cp%3E%5C%5C%20%5Ctheta%3D%5Cfrac%7B7%7D%7B8%7D%5Cpi)

Answer:
We can find the volume of a sphere using the volume of a cylinder. Cylinder is a solid which has a circular base. We know the fact that the volume of any solid is equal to the product of base area and height of the solid. So, the volume of a right circular cylinder of base radius ‘r’ and height ‘h’ is given by
