Answer:
Step-by-step explanation:
The total cost for Nayeli to enter the amusement park is $40. If she goes on 9 rides, the cost for the rides would be 9 * $2 = $18. Therefore, the total cost for Nayeli to enter the park and go on 9 rides would be $40 + $18 = $58.
To find the total cost if she goes on r rides, we can use the formula:
Total cost = $40 + r * $2
So, if Nayeli goes on r rides, she would have to pay $40 + r * $2 in total.
To calculate the total cost, multiply the number of rides by the cost per ride and add it to the admission price.
To calculate the total amount Nayeli would have to pay if she goes on 9 rides, we need to first calculate the cost of admission. The admission price is $40. Then, we multiply the number of rides (9) by the cost per ride ($2) and add it to the admission price to get the total cost.
Total cost = Admission price + (Number of rides x Cost per ride) = $40 + (9 x $2) = $40 + $18 = $58.
If Nayeli goes on 'r' rides, we can use the same formula to calculate the total cost. The total cost would be the admission price ($40) plus the product of the number of rides ('r') and the cost per ride ($2). Total cost = $40 + (r x $2) = $40 + $2r.

© 31. Think About a Plan The Millenium Wheel, also known as the London Eye, contains 32 observation cars. Determine the angle of rotation that will bring Car 3 to the position of Car 18. • How do you find the angle of rotation that a car travels when it moves one position counterclockwise?
• How many positions does Car 3?
The angle of rotation that will bring Car 3 to the position of Car 18 is 11.25 degrees. The angle of rotation that a car travels when it moves one position counterclockwise is 168.75 degrees. Car 3 needs to move 15 positions counterclockwise to reach Car 18.
a. We have to determine the angle of rotation that will bring Car 3 to the position of Car 18 on the London Eye, so we will first calculate the number of positions that Car 3 needs to move counterclockwise to reach Car 18.
We know that there are 32 observation cars on the London Eye, so the distance between two adjacent cars will be 360/32 = 11.25 degrees.
b. To find the angle of rotation that a car travels when it moves one position counterclockwise, we will divide the full rotation of the London Eye by the number of observation cars (i.e. 32).
360/32 = 11.25 degrees
Next, to determine the angle of rotation that would bring Car 3 to the position of Car 18, we will multiply the number of positions that Car 3 needs to move counterclockwise and the angle of rotation for each position as follows -
15 x 11.25 = 168.75 degrees
Therefore, the angle of rotation that a car travels when it moves one position counterclockwise is 168.75 degrees.
c. To find the number of positions that Car 3 needs to move counterclockwise to reach Car 18, we will subtract the position number of Car 18 from that of Car 3 and then take the absolute value, as it is a cyclical rotation.
|18 - 3| = 15
Hence, Car 3 needs to move 15 positions counterclockwise to reach Car 18.

Part B: Logan made a profit of $235 as a mobile groomer. He charged $75 per appointment and received $40 in tips, but also had to pay a rental fee for the truck of $10 per appointment. Write an equation to represent this situation and solve the equation to determine how many appointments Logan had. (5 points)
Answer:
# of appointments is 3
Step-by-step explanation:
He makes $75 per appointment, which means this immediate value is directly dependent on the number of appointments (x). So it can be given by 75x.
Tips are simply added, tips are not directly dependent on the number of visits as customers will tip differently so we can add $40 to the equation.
Now we must negate the expenses, each appointment there is a fee of $10. So it can be given as 10x.
We know that this all must equal $235.
So the equation is as follows:
235 = (75x)+40-(10x)
Simplifying we get
235 = 65x + 40
195 = 65x
195/65 = x
x = 3
Therefore, Logan had 3 appointments.

Casey Na's average workweek during the first quarter of the year (13 weeks) was 43 hours. As part of his company's perfect attendance program, he earned a bonus of $975. Determine the extra overtime pay due Na for the first quarter
Casey Na is due an extra overtime pay of $1,170 for the first quarter as part of his company's perfect attendance program.
What is overtime pay?
Overtime pay is the additional compensation paid to an employee for any hours worked in excess of the standard working hours or beyond the standard workweek. The rate of overtime pay is usually higher than the regular rate of pay for an employee's normal working hours.
To determine the extra overtime pay due to Casey Na for the first quarter, we need to know his regular pay rate and the number of hours he worked each week.
Let's assume that Casey Na's regular pay rate is $20 per hour and that he worked 40 hours each week during the first quarter. This means that he worked 3 hours of overtime each week, for a total of 39 hours at his regular rate and 3 hours at his overtime rate.
To calculate his overtime pay for the first quarter, we can use the following formula:
Overtime pay = overtime hours x overtime rate
Since Casey Na worked 3 hours of overtime each week for 13 weeks, his total overtime hours for the first quarter were:
Total overtime hours = 3 hours/week x 13 weeks = 39 hours
His overtime rate is 1.5 times his regular rate, or $20 x 1.5 = $30 per hour.
Therefore, his overtime pay for the first quarter was:
Overtime pay = 39 hours x $30/hour = $1,170
Since he also earned a bonus of $975 for perfect attendance, his total extra pay for the first quarter was:
Extra pay = Overtime pay + Bonus = $1,170 + $975 = $2,145
Therefore, Casey Na is due an extra overtime pay of $1,170 for the first quarter as part of his company's perfect attendance program.

In the similar triangle, x = 67.5 ft
What are similar triangles?Similar triangles are triangles in which the ratio of their sides are equal.
How to find the value of x?Given the similar triangles, ΔMNP and ΔMAB
By the ratio of similar triangles, we have that
MP/MN = MB/MA
We observe that MN = MA + AN
So, MA = MN - AN
So, MP/MN = MB/MA
MP/MN = MB/(MN - AN)
Given that
MP = 97.5 FT, MN = 71.5 FT, AN = 22 FT and MB = xWe have that
MP/MN = x/(MN - AN)
Making x subject of the formula, we have that
x = (MN - AN)MP/MN
So, substituting the values of the variables into the equation, we have that
x = (MN - AN)MP/MN
x = (71.5 ft - 22 ft)97.5 ft/71.5 ft
x = 49.5 ft × 97.5 ft/71.5 ft
x = 4826.25 ft²/71.5 ft
x = 67.5 ft

The solution of the equation 16g + 3 = 4 - 13g is g = 1/29
An equation is a statement that two expressions are equal. In other words, it's a mathematical sentence that says that the value on the left side of the equation is equal to the value on the right side.
In your problem, you have the equation:
16g + 3 = 4 - 13g
To solve this equation, the goal is to isolate the variable "g" on one side of the equation, so we can find its value. To do that, we need to use some algebraic techniques.
First, we can simplify the equation by combining like terms. We can add 13g to both sides of the equation to get:
16g + 13g + 3 = 4
Now we can combine the like terms on the left side of the equation:
29g + 3 = 4
Next, we want to isolate the variable "g" on one side of the equation. To do that, we can subtract 3 from both sides of the equation:
29g = 1
Finally, we can solve for "g" by dividing both sides of the equation by 29:
g = 1/29
So the solution to the equation is g = 1/29.

Answer:
since y = 0 when x = 0
Step-by-step explanation:
We can start by solving for y in the equation:
y * x = 3/5 y
Dividing both sides by y:
x = 3/5
So the equation y * x = 3/5 y can be simplified to:
y = 5/3 x
This equation shows that there is a proportional relationship between y and x, where y is always equal to 5/3 times x. This relationship can be represented on a graph by plotting points (x, y) and drawing a line through them. The slope of the line will be 5/3, and the y-intercept will be 0, since y = 0 when x = 0.
