Answer:

Step-by-step explanation:
![\sqrt{8} = \sqrt{4*2} = \sqrt{4} * \sqrt{2} = 2*\sqrt{2} = 2\sqrt{2} \\\\\sqrt[3]{8} = \sqrt{2*2*2} = 2](https://tex.z-dn.net/?f=%5Csqrt%7B8%7D%20%3D%20%5Csqrt%7B4%2A2%7D%20%3D%20%5Csqrt%7B4%7D%20%2A%20%5Csqrt%7B2%7D%20%3D%202%2A%5Csqrt%7B2%7D%20%20%3D%202%5Csqrt%7B2%7D%20%5C%5C%5C%5C%5Csqrt%5B3%5D%7B8%7D%20%3D%20%5Csqrt%7B2%2A2%2A2%7D%20%20%3D%202)
Answer:
Hence it will take 35hours
Step-by-step explanation:
Let the time it took to dig hole be x
Ley the number of holes be n
Using the relationship x = kn (direct relationship)
if it takes 3 men 5 hours to dig 12 holes, hence;
when x = 5, n = 12
k = x/n
k = 5/12
To get how many hours it take for 3 men to dig 84 holes, then;
when n = 84, x = ?
x = 5/12 * 84
x = 5 * 7
x = 35hours
Hence it will take 35hours
Answer:
D. 132 words in 6 minutes
Step-by-step explanation:
First, find the amount of words Mark can type in one minute:
44/2 = 22
Mark can type 22 words in 1 minute.
Next, solve by multiply each minute with words per minute to get the total words.
For choice D):
6 x 22 = 132
D) is your answer.

Answer:
C. 5
Step-by-step explanation:
Mean: Numbers over amount of numbers
(2 + 4 + 5 + 6 + 8)/5
25/5

In real-life physics, acceleration due to gravity will change respect to altitude. Check out the attached image (source: Wikipedia).
However, in high-school physics, acceleration due to gravity is represented by the letter g, which has a value of 9.81 meters per second squared.
This means that an object being dropped straight down will be moving 9.81 meters per second faster than it was 1 second ago. I hope this helps! :)
