100x = 75.757575...
- x = 0.757575...
-----------------------------
99x = 75
x = 75/99
x = 25/33
Answer: 0.757575... = 25/33
First add the biggest number like thousand together and the go in to the last numbers
Finding two geometric means between 10 and 125:
a 1 = 10, a 4 = 1250
a 4 = a 1 * q^3
1250 = 10 * q^3
q^3 = 1250 : 10
q^3 = 125
q = 5
a 2 = 10 * 5 = 50
a 3 = 10 * 5² = 10 * 25 = 250
Answer: The two geometric means are: 50 and 250, since 10, 50, 250 , 1250 forms a geometric sequence.
<h2>
Answer:</h2>
The the number of students who sign up for all three clubs = 6
<h2>
Step-by-step explanation:</h2>
The total number of students in the class is given by:
Total number of students= Number of students in poetry club+Number of students in history club+Number of students in writing club-Number of students in exactly 2 clubs-2×Number of students in all the three clubs.
Based on the information we have:
Total number of students= 59
Number of students in poetry club= 22
Number of students in history club= 27
Number of students in writing club= 28
and number of students in exactly two clubs=6
Let the number of students in the three club= x
Hence, we have:
59=22+27+28-6-2x
i.e.
59=71-2x
i.e.
2x=71-59
i.e.
2x=12
i.e.
x=6
Hence, the answer is: 6
