Choice B the cos is the adjacent side of the angle over the hypotenuse
Answer:
1331:216
Step-by-step explanation:
Given the ratio of the lengths of two similar solids as a:b
The ratio of the surface areas = 
The ratio of the volume = 
We are given that the ratio of the surface areas of two similar geometrical solids is given by 121:36
Therefore:

Since the ratio of the lengths is 11:6
The ratio of their volumes = 
=1331:216
The ratio of the volume of the two similar geometrical solids is 1331:126.
Answer:
Step-by-step explanation:
<u>Given points </u>
<u>Use slope formula to find the slope</u>
- m = (y2 - y1)/(x2 - x1)
- m = (-7 -5)/(1 + 2) = -12/3 = -4
Slope is -4
Answer:
1356 cm²
Step-by-step explanation:
Each dimension gets multiplied by 2, so the new dimensions are
changed from 2x8x7 to 6x24x21
There are 6 faces to the prism,
The area of the front and back are 6x21 = 126. There are 2 of them for a total area of 126x2 = 252 cm²
The are of the left and right sides are 24x21 = 504. There are 2 of them for a total area of 504x2 = 1008 cm²
The area of the top and bottom are 6x24 = 144, there are 2 of them for a total area of 144x2 = 288 cm²
The total surface area is 252 + 1008 + 96 = 1356 cm²
