Step-by-step explanation:
An airline charges $(22x+20) for a ticket, $(x+1) to check a bag, $2x for food, and $(15x-16) to upgrade to first class. Write an expression to represent the total cost of flying first class, checking the bag, and buying food on the plane
$ (40x + 5) is the expression to represent the total cost of flying first class, checking the bag, and buying food on the plane
Solution:
Given that,
Charge for ticket = $ (22x + 20)
Charge for checking bag = $ (x + 1)
Charge for food = $ 2x
Charge to upgrade to first class = $ (15x - 16)
To find: Expression to represent the total cost of flying first class, checking the bag, and buying food on the plane
Total cost = Charge for ticket + Charge for checking bag + Charge for food + Charge to upgrade to first class
[tex]Total\ Cost = (22x + 20) + (x + 1) + (2x) + (15x-16)\\\\Total\ Cost = 22x + 20 + x + 1 + 2x + 15x - 16\\\\\text{Combine the like terms}\\\\Total\ Cost = 40x+5[/tex]
Thus the expression to represent total cost is $ 40x + 5
Final answer:
The expression to calculate the total cost of flying first class, checking a bag, and buying food on the airline is calculated by adding the individual expenses, resulting in the simplified expression Total Cost = 40x + 5, where x is the variable that represents part of the costs.
Explanation:
To represent the total cost of flying first class, checking a bag, and buying food on the plane, we need to add the individual costs together. The airline charges $(22x+20) for a ticket, $(x+1) to check a bag, $2x for food, and $(15x-16) to upgrade to first class. Adding these costs together gives us the total cost:
Total Cost = Ticket + Bag + Food + Upgrade
Total Cost = (22x + 20) + (x + 1) + (2x) + (15x - 16)
Combining like terms, the expression simplifies to:
Total Cost = (22x + x + 2x + 15x) + (20 + 1 - 16)
Total Cost = 40x + 5
This expression can be used to calculate the total cost of flying first class with this airline, depending on the value of x.

Use long division to find the value of 5.04 divided by 7
Final answer:
Long division is used to divide 5.04 by 7, giving a quotient of 0.72. We divide 50 by 7 to get 7, then bring down the 0 and 4 consecutively, resulting in 1 and 4 added to the quotient line, respectively.
Explanation:
When you use long division to divide 5.04 by 7, you start by placing the divisor (7) outside the division box and the dividend (5.04), with the decimal point, inside the box. You then determine how many times 7 goes into 50 (the number before the decimal point in 504), which is 7 times. Therefore, you place a 7 above the 50, on the quotient line. Next, you multiply 7 by 7 to get 49, and subtract that from 50, resulting in 1. Shift down the next digit from the dividend, which is 0, making the new number 10. Seven goes into 10 once, so you put another 1 on the quotient line, multiply 7 by 1 giving 7, and subtract again, resulting in 3. Lastly, you bring down the last digit, which is 4, to get 34. Five goes into 34 four times, giving us a final quotient of 0.72.
For a car moving at a constant speed, the distance traveled varies directly with the time spent driving. If such a car travels 270 miles in 6 hours, how many miles does it travel in 8 hours?
Answer:
Step-by-step explanation:
Let the distance be D and time T.
D ∞ T
D = kT
Where k is the constant of proportionality.
k = D/T
When D = 270miles & T = 6hours
k = 270/6
k = 45
:- D = 45T
When T = 8hours
D = 45 × 8
D = 360miles

To find the total number of people riding the bus throughout the day, we calculate the evening ridership by subtracting 10 from 84, giving us 74 evening riders. We then add this number to the 197 morning riders to get a total of 271 riders for the day.
Explanation:The question asks us to find the total number of people who ride the bus throughout the day by considering both morning and evening ridership numbers. In the morning, 197 people ride the bus. For the evening, it is mentioned that there are 10 less than 84 people riding the bus.
To find out the number of evening riders, we subtract 10 from 84:
84 - 10 = 74 people ride the bus in the evening.
Now, we add the number of morning riders to the number of evening riders to get the total:
197 + 74 = 271 people ride the bus in all.

SA = [?] cm?
The student's question lacks necessary details to compute the surface area of the composite figure. Generally, surface area is calculated by summing the areas of each face. For cubes, multiply the area of one face by six and adjust for unexposed areas in composites.
Explanation:The question asks for the total surface area of a composite figure, but the question does not give enough details about the specific shape or composition of the figure. Typically, to find the surface area of any 3-dimensional shape, you'd sum the areas of all the individual faces. For example, for a cube, you'd calculate the area of one face (side length squared) and multiply by 6, because a cube has 6 faces.
In this scenario, if the composite figure was a combination of cubes, you would calculate the total surface area by finding the surface area of each cube separately (surface area of a cube = 6 x side length squared) and then adjust for any faces that are not exposed. The total surface area is the sum of the surface areas of each part of the composite figure minus any overlapping areas.
Without the complete details of the figure, I cannot provide a numerical answer, but I hope this explanation helps you understand the steps involved in computing surface area for composite figures.

Evaluate the sum of the finite geometric series 4+12+36+108....+972
To find the sum of the finite geometric series 4 + 12 + 36 + 108 + ... + 972, we use the sum formula for geometric series. The common ratio is 3, and there are 6 terms in the series. The sum of the series is 1456.
Evaluating the Sum of a Finite Geometric Series:
To evaluate the sum of the finite geometric series 4 + 12 + 36 + 108 + ... + 972, you need to use the formula for the sum of a finite geometric series:
Sum = a ×([tex]r^{n}[/tex] - 1) / (r - 1)
where:
a is the first term of the seriesr is the common ration is the number of termsLet's identify these values:
First term, a = 4Common ratio, r = 12 / 4 = 3Number of terms, nTo find n, use the formula for the nth term of a geometric series: a * r^(n-1). Given the last term is 972, we solve:
4 × [tex]3^{n-1}[/tex]= 972
Divide both sides by 4:
[tex]3^{n-1}[/tex]= 243
Recognize that 243 = [tex]3^{5}[/tex], so:
n-1 = 5
n = 6
Now, apply the sum formula:
Sum = 4 × ([tex]3^{6}[/tex] - 1) / (3 - 1)
Simplify the expression:
Sum = 4 × (729 - 1) / 2
Sum = 4 × 728 / 2
Sum = 4 × 364
Sum = 1456
Therefore, the sum of the series 4 + 12 + 36 + 108 + ... + 972 is 1456.
