The Ratio of the boy's allowance to his sister's is 5 : 4.

The new Ratio is 1 : 10000.

<h3>What is definition of ratio?</h3>
  • The quotient of two mathematical expressions, 1a. b: the proportion between two or more items in terms of quantity, amount, or size.
  • What does the arithmetic term "ratio" mean?
  • An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
  • For instance, if there is 1 boy and 3 girls, you may express the ratio as 1: 3 (there are 3 girls for every boy), meaning that there are 1 in 4 boys and 3 in 4 girls.

1.50c + 2.50a = 1100
c + a = 500

multiply the second equation by -1.50
                    
                      1.50c + 2.50a = 1100
-1.50c - 1.50a = -7.50

Part III: Bailey works part-time at a movie theater. The theater pays employees an hourly wage based on their length of employme
frutty [35]
Given the following table showing the hourly wages of employees of a movie theater based on their length of employment.

<span>Length of employment (months)         Hourly wage (dollars/hour)
6 months                                                          7.55
12 months                                                        7.85
18 months                                                        8.15
24 months                                                        8.45

To obtain an algebraic expression </span>that describes how much Bailey’s employer pays part-time workers, we take two points from the table.

Recall that the equation of a linear function satisfying two points
(x_1,y_1) and (x_2,y_2)
is given by
\frac{y-y_1}{x-x_1} = \frac{y_2-y_1}{x_2-x_1}

Given the two points (6, 7.55) and (12, 7.85), the algebraic expression relating the two points is given by
\frac{y-7.55}{x-6} = \frac{7.85-7.55}{12-6} = \frac{0.3}{6}  \\  \\ 6(y-7.55)=0.3(x-6) \\  \\ 6y-45.3=0.3x-1.8 \\  \\ 0.3x-6y=-43.5

Therefore, the <span>algebraic expression that describes how much Bailey’s employer pays part-time workers is
0.3x-6y=-43.5</span>

If <br>a+e = 11<br>a²-f=15<br>f+c=6<br>c×a-e=13<br>what is the value of the variables​
CaHeK987 [17]

Answer:

a=4

c=5

e=7

f=1

Step-by-step explanation:

the simplest method would be to start with a(2)"squared" (being '4' as this will get you closest to 15. So 16 -1 (being 'c') = 15. now plug those into the other equations and work the other numbers out.
