Answer:
25/6
Step-by-step explanation:
The direct variation tells you that y is proportional to x. That means a reduction by a factor of 5/6 as x changes from 6 to 5 will result in a reduction of y by the same factor.
y = (5/6)(5) = 25/6
I’m pretty sure this answer is B
The measure of arc EF = 146 degrees because its central angle = 146 degrees.
Answer : The correct option is, (B) 1500 cubic yards.
Step-by-step explanation :
Formula used to calculate the volume of square pyramid is:
![V=\frac{a^2\times h}{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7Ba%5E2%5Ctimes%20h%7D%7B3%7D)
where,
V = volume of pyramid
a = base edge of pyramid
h = height of pyramid
Given:
Base edge of pyramid = 15 yards
Height of pyramid = 20 yards
Now putting all the given values in the above formula, we get:
![V=\frac{a^2\times h}{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7Ba%5E2%5Ctimes%20h%7D%7B3%7D)
![V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B%2815%5Ctext%7B%20yrads%7D%29%5E2%5Ctimes%20%2820%5Ctext%7B%20yards%7D%29%7D%7B3%7D)
![V=1500\text{ yards}^3](https://tex.z-dn.net/?f=V%3D1500%5Ctext%7B%20yards%7D%5E3)
Therefore, the volume of pyramid is 1500 cubic yards.
