Step-by-step explanation:
Steven earns extra money babysitting. He charges $40.50 for 6 hours and $54.00 for 8 hours. Enter an equation to represent the relationship. Let x represent the number of hours Steven babysits and y represent the amount he charges.
Answer:
6.75 * x =y
Step-by-step explanation:
In this question, for is a keyword here we can use to represent division. If he charges $40.50 for 6 hours, this means we can represent this as [tex]\frac{40.50dollars}{6 hours}[/tex] to calculate the amount babysitting costs for an hour. Our answer is then [tex]\frac{6.75 dollars}{1 hour}[/tex]. A similar division of $54.00 for 8 hours results in a calculation of [tex]\frac{54.00 dollars}{8 hours} = \frac{6.75 dollars}{1hour}[/tex]. This means that for each hour, he charges 6.75 dollars, the same amount of money each hour.
Given this information, we can say that an equation to represent this relationship would be that, to calculate the total money Steven earns, we can multiply 6.75 dollars by the amount of hours he works, as he earns 6.75 dollars for each hour, making our equation 6.75 * x =y, with y representing the total amount he charges.

Jill calls a plumber to her house to fix the leaking faucets . The plumber charges a one-time fee of $50 plus an additional $35 per hour of labor. What are the independent and dependent variables
Answer:
independent=$50
dependent=$35X
Step-by-step explanation:
50 is the independent variable because it doesn't change.
35X is the dependent variable because it does change.
In this scenario, the independent variable is the number of hours of labor and dependent variable is the total cost.
The independent variable is the number of hours. It is the variable that we can control or change.
The dependent variable is the total cost charged by the plumber.
It depends on the number of hours of labor and is determined by the plumber's fee structure, which includes a one-time fee of $50 plus $35 per hour of labor.
The total cost is calculated based on the number of hours of labor, making it the dependent variable in this situation.

You and your family need to take a taxi to get around town on
your vacation. The taxi service charges $7.50 for the initial
pickup of you and your family and $0.25 per mile. Write an
equation to represent this situation. Then, calculate how much
it would cost if you took the taxi for a 12 mile trip.
Equations
Solutions
y = 0.25x + 7.75
А A
$10.50
3
y = 7.50x + 0.25
B
$18.00
y = 0.25x + 7.50
$90.25
5
Answer:
Equation: y = 0.25x + 7.50
Cost: $10.50
Step-by-step explanation:
Let x be the number of miles and y be the total cost in $.
y = 0.25x + 7.50
If we want to find the total cost of a 12 mi trip, we plug in x=12.
y = 0.25 * 12 + 7.50
y = 3 + 7.50
y=10.50

Resuelve el siguiente problema aplicado al sistema de ecuaciones, utilizando cualquiera de los tres métodos aprendidos: Sergio tiene $ 1.950 en monedas de $ 100 y de $ 50. En total tiene 24 monedas. Determina cuántas monedas son de $ 100 y cuántas de $ 50.
Answer:
Tiene 9 monedas de $50 y 15 monedas de $100.
Step-by-step explanation:
Sergio tiene $1950 en monedas de $100 y $50, entonces la primera ecuación es la siguiente:
[tex] 100x + 50y = 1950 [/tex] (1)
Ahora, en total tiene 24 monedas:
[tex] x + y = 24 [/tex] (2)
De la ecuación (2) tenemos:
[tex] x = 24 - y [/tex] (3)
Ahora introduciendo la ecuación (3) en la ecuación (1) y resolviendo para "y" nos queda:
[tex] 100(24 - y) + 50 y = 1950 [/tex]
[tex] 2400 - 100y + 50y = 1950 [/tex]
[tex] y = \frac{450}{50} = 9 [/tex]
Con la ecuación (3) podemos hallar el valor de "x":
[tex] x = 24 - 9 = 15 [/tex]
Por lo tanto, tiene 9 monedas de $50 y 15 monedas de $100.

A. y = -x + 1
B. y = x - 1
C. y = -x - 1
D. y = x + 1
Answer:
y =x+1
Step-by-step explanation:
The y intercept is 1
The slope is positive
We go up 1 and to the right 1
y = mx+b where m is the slope and b is the y intercept
y = 1x+1
y =x+1
Find the volume of this cone.
Round to the nearest tenth.
10ft
6ft
Answer:
301.6 ft³
Step-by-step explanation:
Volume of the cone = ⅓*πr²h
Where,
radius (r) = 6 ft
height (h) = √(10² - 6²) => Pythagorean theorem
h = √(100 - 36)
h = √64
h = 8 ft
Plug in the values
Volume = ⅓*π*6²*8
Volume = 301.6 ft³ (nearest tenth)

If 137 is subtracted from three times of square of a natural number the result is 55. Find the number
Answer:
8
Step-by-step explanation:
Let the unknown number be x.
Therefore, we can write the question as a mathematical statement and this will be:
3x^2 - 137 = 55. (Note: ^2 = to the power of 2 or "squared"
(In the question, we can break it up as being three times of a square of a natural number = (3x^2) and 137 is subtracted from = (- 137) and the result is 55 = (= 55). Therefore, this gives 3x^2 - 137 = 55
Then, we add 137 first to get rid of the (-137)
Therefore:
3x^2 = 192
Then, we divide 3 from both sides to get rid of the (3) in (3x^2).
Therefore,
x^2 = 64.
So, we square root 64. This gives
x = 8.
Therefore, the answer is 8.

A store decreases the price of a sofa by 16% this month only, to $5200. What was the price before the
discount
9514 1404 393
Answer:
$6190.48
Step-by-step explanation:
The price is now 1 -16% = 84% of the original price (p).
$5200 = 0.84p
p = $5200/0.84 = $6190.48
The price before the discount was $6190.48.
