Answer:
i. 7:6
ii. 7:13
iii. 6:13
Step-by-step explanation:
boys to girls = 140:120 so we can simplify by 20 to get 7:6
boys to total = 140:(120+140) = 140:260 we can simplify again to get 7:13.
girls to total = 120:(120+140) = 120:260 we can also simplify to get 6:13
what is the answer please
Answer: You know what's the answer...... it is 159.32
Hope it helps :)

In how many ways can the survey be answered?
Our survey asked teens to place a 1, 2, 3, 4, or 5 next to each type of music Our survey lists country, classical hip-hop, oldies, and
alternative as music options. That's going to give us a bunch of answer
arrangements In this graphic, the students are ranking the musics: country, classical, hip-hop, oldies, and alternative from 1-5. So in how many ways can they be surveyed?
The number of ways the survey can be answered is an illustration of selection
The survey can be answered in 625 ways
How to determine the number of waysThe options are given as: 1 to 5
The types of music are given as: country, classical hip-hop, oldies, and
alternative
There are 4 music types.
This means that any of the 5 options 1 - 5 can be selected for each of the 4 music types.
So, the number of ways (n) is:
[tex]n = 5^4[/tex]
Evaluate the exponent
[tex]n = 625[/tex]
Hence, the survey can be answered in 625 ways

24) area= 16 pi inches squared
Find the circumference
It doesn't give any pictures
Answer:
8π in
Step-by-step explanation:
The Area of a Circle is πr². In this case, we're given the area as 16π, so the radius is 4 because the square root of 16 is 4.
The Circumference of a Circle is 2πr. Since the radius is 4:
[tex]2*4 * \pi[/tex] [tex]8\pi[/tex]Therefore, the circumference is 8π inches.

Which point lies outside of the solution set? (y+4)^2/9-(x+1)^2/9>1
The point outside the solution set are the false values of the inequality
The point outside the solution set of (y+4)^2/9-(x+1)^2/9>1 is (-1,-1)
How to determine the point outside the solution setThe inequality of the graph is given as:
[tex]\frac{(y+4)^2}{9}-\frac{(x+1)^2}{9} > 1[/tex]
Next, we test the options
Option A. (-2,4)This gives
[tex]\frac{(4+4)^2}{9}-\frac{(-2+1)^2}{9} > 1[/tex]
[tex]\frac{64}{9}-\frac{1}{9} > 1[/tex]
Evaluate the difference
[tex]7 > 1[/tex] -- this is true
Option B. (2,-12)This gives
[tex]\frac{(-12+4)^2}{9}-\frac{(2+1)^2}{9} > 1[/tex]
[tex]6.1 > 1[/tex] -- this is true
Option C. (-1,-1)This gives
[tex]\frac{(-1+4)^2}{9}-\frac{(-1+1)^2}{9} > 1[/tex]
[tex]1 > 1[/tex] -- this is false
Hence, the point outside the solution set of (y+4)^2/9-(x+1)^2/9>1 is (-1,-1)

Solve for b 6b + 16 = 94
Answer:
b=13
Step-by-step explanation:
First, subtract 16 from 94. 94-16=78
Then divide 6 into 78. 78/6=13
Therefore, b=13
Answer:
b=13
Step-by-step explanation:
6b+16=94
subtract 16 from both sides
6b=78
divide both sides by 6
b=13

What is the equation of the vertical asymptote for the graph below? y=1/x−2
very cheap answer
vertical asymptoes occur when the denominator turns to zero, in this case we know the denominator is x - 2, so let's zero it out, by x - 2 = 0, thus x = 2, that's the equation of the vertical asymptote, or namely, the vertical line of x = 2 marks the line where the graph glides over but never touches it.
