Q4: are questions 1 and question 3 the same? (yes or no)
Answers
Answer:
1,2,3 are all the same
Step-by-step explanation:
for the math problem, the answer is 13.63%.
The answers are as follows:
Q1: 65%
Q2: 25%
Q3: 46.42%
Q4: No
What is Percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred.
As per the given data:
The table gives us the data on male, female and total drivers with respect to the car they drive.
For percent of males that drive sports cars:
= (males who drive sports car / total male drivers) × 100
= (39/60) × 100
= 65%
For percent of all drivers that are male:
= (male drivers / total drivers) × 100
= (60/240) × 100
= 25%
For percent of sports car drivers that are male:
= (male sports car drivers / total sports car drivers) × 100
= (39/84) × 100
= 46.42%
Question 1 and question 3 are not the same.
Hence, the answers are as follows:
Q1: 65%
Q2: 25%
Q3: 46.42%
Q4: No

"The school band decided to raise money by holding a car wash. The band spent $32 to buy the needed supplies. They will charge $5 for each car they wash.
Part A: Create a table showing the profit (total money minus expenses) that the band will make for washing 1 through 10 cars. [Table shown]
Part B: What will be the band's profit for washing 40 cars?
Part C: What is the minimum number of cars the band needs to wash to start making a profit?
Part D: Write the linear equation that would represent the profit earned by washing C number of cars."
Answers
Answer:
Scroll Down Below...
Step-by-step explanation:
Part A: Table show the profit for washing 1 through 10 machines:| Number of Cars (C) | Total Money Earned | Expenses | Profit 1
| 1 | $5 | $32 | -$27 |
| 2 | $10 | $32 | -$22 |
| 3 | $15 | $32 | -$17 |
| 4 | $20 | $32 | -$12 |
| 5 | $25 | $32 | -$7 |
| 6 | $30 | $32 | -$2 |
| 7 | $35 | $32 | $3 |
| 8 | $40 | $32 | $8 |
| 9 | $45 | $32 | $13 |
| 10 | $50 | $32 | $18 |
|Part B: To find the band's profit for washing 40 convertibles, we can use the undeviating equating:Profit = (Total Money Earned) - ExpensesThe total services gained for washing 40 automobiles is:Total Money Earned = $5 x 40 = $200Substituting the principles into the equating:Profit = $200 - $32 = $168Therefore, the band's profit for washing 40 rides is $168.Part C: The minimum number of buses the band needs to wash to start making a profit maybe contingent upon judgment the point place the profit enhances beneficial. From the table, we can visualize that the band starts making a profit when they wash 7 machines. So the minimum number of buses the band needs to wash to start making a profit is 7.Part D: The uninterrupted equating that shows the profit gained by washing C number of jeeps maybe composed as:Profit = (Total Money Earned) - ExpensesThe total services won for washing C machines is:Total Money Earned = $5CSubstituting the principles into the equating:Profit = $5C - $32Therefore, the undeviating equating illustrating the profit won by washing C number of rides is:Profit = $5C - $32
Answer:
A: see attached
B: $168
C: 7
D: profit = 5C -32
Step-by-step explanation:
You want the profit earned by a school band after spending $32 for supplies when they charge $5 for each car washed.
A: TableThe attachment shows a table of earnings and profit for 1–10 cars and for 40 cars (Part B).
B: 40 CarsThe last line of the attached table shows the profit for washing 40 cars is $168.
The profit for washing 40 cars is $168 because it is the amount resulting from subtracting the expenses of $32 from the revenue of $5 × 40 = $200.
C: Break evenThe highlighted line in the table shows the first positive profit is made by washing 7 cars.
The minimum number of cars the band needs to wash to start making a profit is 7.
D: EquationThe equation for the profit will reflect that profit is the difference between the revenue and the expenses:
profit = 5C -32
__
Additional comment
A spreadsheet is handy for making the table. The (money earned) column is 5 times the (# of cars) column, reflecting the $5 per car charge. The expense is then subtracted to give the value in the profit column. The last line shows it is easy to find the profit associated with any particular number of cars being washed. Effectively, the equation for profit is embedded in the table formulas.

Sky High TV is a satellite television provider. They charged about a month. The first month of service costs 85.45. After the second month, the total cost is $148.65. After the third month, the total cost is $211.85. An equation in the form of y = c + d(x - 1) to represent the situation. Define the variables. ____________________________________________________________________________________________________________________________________________________________________________________________________________
Answers
Answer: y = 63.20x + 22.25, where x is the number of months and y is the total cost.
Step-by-step explanation:
Let's start by finding the value of the constant term c. We know that the first month of service costs $85.45, so we have:
y = c + d(x – 1)
85.45 = c + d(1 – 1)
85.45 = c
Now we need to find the value of the slope d. We can use the information from the second and third months:
y = c + d(x – 1)
148.65 = 85.45 + d(2 – 1)
63.20 = d
y = c + d(x – 1)
211.85 = 85.45 + d(3 – 1)
126.40 = 2d
Simplifying the second equation, we get:
63.20 = d
Substituting the values of c and d into the equation, we get:
y = 85.45 + 63.20(x – 1)
y = 63.20x + 22.25
Therefore, the equation that represents this situation is:
y = 63.20x + 22.25, where x is the number of months and y is the total cost.

Step-by-step explanation:
We know that being complementary angles refer to..Sum of two angles = 90°.
So,
<A + <B = 90
i.e. (7x + 25) + (x+9) = 90
or, 8x + 34 = 90
or, 8x = 90-34
or, x = 56/8
or, x = 7
Again,
<A = 7x + 25
or, <A = 7*7 + 25

12,455 + x = 23,894
x = 10,560
Step-by-step explanation:
Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:
10,205 + x = 23,894
To solve, we must isolate the variable by subtracting 12,455 from both sides:
10,205 + x = 23,894
-10,205 -10,205
x = 10,560
So, the second month's salary was $10,560
Step-by-step explanation:
Answer: x = $30,560
Step-by-step explanation:
1. Let the second month payment be x
2. The first month + The second month = both of the months
3. So substituting: 10,205 + x = 40,765
4. Subtract 10,205 from both sides: x = 30,560

-7/15
Step-by-step explanation:
You want to isolate the d variable so you take out anything on the side of d to make d alone. To make d isolate the 15/42 has to go.
So...multiply
\(\frac{15}{42}\)* \(\frac{42}{15}\) right side
the answer to the equation above is 1. d is now alone, because 1*d is just d.
Since you multiplied 42/15 on the right, you've to do the same thing on the left.
\(\frac{42}{15}\)*\((-\frac{1}{6})\) left side
Divide the 6 by itself and also by 42. Or multiply the numerator and denominator.
The answer you get is -7/15.
