The ratio of people in its simplest form is 1 : 3
The ratio of benches in its simplest form is 1 : 4
What is the ratio in simplest form?A ratio is the number representing a comparison between two named things.
It also refers to the relative magnitudes of two quantities usually expressed as a quotient.
For instance, if there are 12 students in a class which includes 8 girls and 4 boys,
The ratio of girls to all students = 8 : 12
= 8/12
= 2/3
= 2 : 3
The ratio of boys to girls = 4 : 8
= 4/8
= 1/2
= 1 : 2
The ratio of all students to boys = 12 : 4
= 12/4
= 3/1
= 3 : 1
Hence,
People = 6 : 18
= 6 / 18
= 3 / 9
= 1/3
= 1 : 3
Benches = 3 : 12
= 3 / 12
= 1 / 4
= 1 : 4
Therefore, the ratio of people and benches in its simplest form is 1 : 3 and 1 : 4 respectively.

Rick buys 18 apples for $13. How much would it cost to buy 24 apples?
Answer:
$33.23
Step-by-step explanation:
If 18 apples cost $13, this means that each apple costs 1.38461538. To find the cost of 24 apples, multiply that decimal number by 24. You will get 33.2307692308. You can round this to 33.23.

The school sold 300 tickets to the theatre performance. They sold adult tickets for $9 each and student tickets for $6 each. They made a total of $2, 190. How many students were in attendance?
PLEASE HELP! I need to show work
Answer:
170 students were attending
Step-by-step explanation:
use a system of equations:
[tex]\left \{ {{x+y=300} \atop {9x+6y=2190}} \right.[/tex]
let x be the adults and y be the students
[tex]\left \{ {{-9(x+y=300)} \atop {9x+6y=2190}} \right.[/tex] multiply the top equation by -9 and add the two systems together to cancel out x. you are then left with:
[tex]-3y=-510[/tex]
divide both sides by -3 to leave y alone:
[tex]\frac{-3y}{-3}=\frac{-510}{-3}[/tex]
that would leave you with:
y=170

The circle below represents one whole.
What percent is represented by the shaded area?
%
Answer:
25%
Step-by-step explanation:
check
1/4 * 100% = 25%
The region represented by the shaded area has 25% and is 1/4th of the total circle.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
The formula to calculate the area of the circle is given as πr², where r is the radius of the circle.
In the given figure the total area of the circle is πr². The shaded region is one-fourth of the total area of the circle.
Total area = πr²
Shaded area = ( 1 / 4 )πr²
The percentage of the shaded area will be calculated as
Shaded area = ( 1 / 4 )πr²
Shaded area = ( 0.25 )πr²
To convert it into a percentage multiply by 100.
Shaded area = ( 0.25 x 100 )πr²
Shaded area =25% πr²
Put πr² as the total area.
Shaded area =25% of Total area.
Therefore, the region represented by the shaded area has 25% and is 1/4th of the total circle.

Answer: Choice A. f(x) = sqrt(x-1)
===========================================
Explanation:
The parent function is y = sqrt(x) and the left-most edge of this curve is at (0,0).
The graph shows the left-most point at (1,0) instead.
This means we've shifted everything 1 unit to the right, or you can think of the xy axis being shifted 1 unit to the left while the square root curve stays still (giving the illusion the curve moves).
If we shifted the xy axis 1 unit to the left, then each input x becomes one smaller, so each input is now x-1
That's why we go from y = sqrt(x) to y = sqrt(x-1)
You can use a graphing calculator to confirm this, or you can create a table of values to generate the points on this new blue curve.
