Answer:
Number of en at the lecture = 18
Step-by-step explanation:
Let the men at lecture be 2x
And women at lecture be 5x.
Remember ratio of men and women is 2 to 5.
Total number of people at the lecture = 63
i.e 2x + 5x = 63
or 7x = 63
or x = 63 /7
or x =9
Hence , Men at the lecture = 2x = 2*9 = 18
And women at the lecture = 5x = 5*9 = 45
Answer:
40%
Step-by-step explanation:
To convert to a percent, we divide the numerator by the denominator. Our answer will be a decimal which we will multiply by 100 to find the percent.
Answer: 11
=========================
Explanation:
To find the inverse, or f^-1 of a function, you first replace the y= 6x-4 with x=6y-4
Finding the inverse from here is basically just finding y in terms of x.
1) x=6y-4
2) x+4=6
3) (x+4)/6= y
y= (x+4)/6 is now your f^-1.
Now that you have your inverse, replace 62 with your x in y=(x+4)/6
1) (62+4)/6
2) 66/6
3) 11
Therefore, f^-1(62)= 11

Answer:
13
Step-by-step explanation:
77−|(−8)(3)+(−10)(4)|
=77−|−24+(−10)(4)|
=77−|−24+−40|
=77−|−64|
=77−64
=13
