Answer:
x=0.00784
Step-by-step explanation:
Answer:
1/10
13/100
4/5
12/25
3/10
63/100
3/5
51/200
2/9
5/11
To prove the last 2 recurring ones:
0.222222... = x
10x = 10 * 0.22222... = 2.222222....
Notice how the decimal part of 10x is the same as for x:
10x - x = 2.2222222... - 0.222222... = 2
10x - x = 9x = 2
x = 2/9
Same procedure for the other one but times by 100 instead:
x = 0.454545...
100x = 45.454545...
100x - x = 45.454545... - 0.454545... = 45
100x - x = 99x = 45
x = 45/99 = 5/11
Answer:
12
Step-by-step explanation:
The geometric mean of the numbers is 5.38
Given the values a, b, c and d
Geometric mean of the values will be expressed as:
GM = (abcd)^1/4
Given the values 4, 5, 6 and 7, the geometric mean will be expressed as:
GM = (4×5×6×7)^1/4
GM = (840)^1/4
GM = 5.38
Hence the geometric mean of the numbers is 5.38.
