Answer:
18.2222222222 mph
Step-by-step explanation:
82 x 4.5 = 18.222222222
The answer is 8.8
You have to use SohCahToa to figure out the length of AB
-12+8x+2x=2x-8
10x-12=2x-8
8x=4
x=1/2
C
Answer:
0.81649658092
Step-by-step explanation:
The square root of 6 equals 2.44948974278. Divide that by 3, and you are given 0.81649658092.
Let's remember the equation for the volume of a cube:
V= x^3 where x is the length of one side
Since a cube has equal length for length, width, and height.
Now, use what you're given
V= 1331
And put that in terms of x
x^3 = 1331
Now solve for x!
x= cube root (1331)
Think about it! cube root of 1331 * cube root of 1331 * cube root of 1331... will equal 1331 m^3!
Hope this helps
