Answer:
M = 6.50n
Step-by-step explanation:
since it is per child, it will be multiplied by the amount of children, n. Therefore giving us the cost of M, or the equivalent.
Well 9x6.4=57.6. Thats the closest to 57
Answer:
1. not a function.
2. is a function.
3. is a function.
4. not a function.
5. is a function.
6. not a function.
7. not a function.
8. is a function.
9. not a function.
10. is a function.
11. not a function.
12. not a function.
Step-by-step explanation:
1. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.
2. is a function because each input only goes to one output.
3. is a function because each input only goes to one output.
4. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It does not pass the vertical line test.
5. is a function because each input only goes to one output.
6. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.
7. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.
8. is a function because each input only goes to one output. It also passes the vertical line test.
9. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.
10. is a function because each input only goes to one output. It also passes the vertical line test.
11. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.
12. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.
Hope this helps!
Answer:
Part a) 
Part b) 132:89 vs 132 to 89
Part c) 
Part d) 66:7 vs 66 to 7
Step-by-step explanation:
Let
x ----> the number of boys
y ----> the number girls
z ----> the number of adults
we have
x=132, y=89, z=14
Part a) Write the ratio of the number of boys to the number of girls.
To find the ratio of the number of boys to the number of girls, divide the number of boys by the number of girls
so

substitute

Part b) Write the same ratio using another form (A: B vs. A to B)
we have

The other form is
132:89 vs 132 to 89
Part c) Write the ratio of the number of boys to the number of adults
To find the ratio of the number of boys to the number of adults, divide the number of boys by the number of adults
so

substitute

Simplify

Part d) Write the same ratio using another form
The other form is
66:7 vs 66 to 7
The perimeter of a polygon (rectangle is a polygon) is the length of the line that forms it. This is, it is the sum of the length of the sides. Given that a rectangle has two pairs of equal sides the perimeter is 2 times one length plus 2 times the other length => 2*84 ft + 2*50 ft = 168 ft + 100 ft = 268 ft. <span>Answer option D. 268 feet.</span>
