snailpace coach company is running a trip to "the anoraks" concert. they have seven 52-seater coaches and eight 12-seater minibuses. the coach company forks out £23 for each ticket. it also costs them £150 to run each coach and £80 per minibus. how much will the company have to pay in total to run the trip

Answers

Total seats: 52 x 7 + 8 x 12 = 364 + 96 = 460

Total cost for total seats = 460 x 23 = 10,580

Cost for buses: 150 x 7 + 80 x 8 = 1050 + 640 = 1690

Total cost = 10,580 + 1,690 = $12,270

Which ideas about functions do you think might be the most helpful to you in your day-to-day planning?

Answers

Answer:

It helps in calculating the price of groceries such as fruits.

Step-by-step explanation:

Remember, functions are mathematical expressions that represent or shows the relationship between one or more variables.

For example, let's say a young girl wants to shop for 20 oranges in a mall. If we express the price using the function [tex]y = 20x[/tex] where;

y represents the total cost of the oranges,

20 represents the number of oranges,

x represents the cost per orange (assumed to $0.99)

Then, by means of the knowledge of function, the girl determines the total cost she to be $19.8 (20*0.99).

Functions are mathematical representation of the relationship which exists between input and output variables. Hence, an helpful day-to-day usage of function could be in calculating daily spending on food items.

One could stipulate the daily amount spent on food based on the number of meals consumed per day.

For instance, if a meal cost $5.60, then the total amount spent on food can be represented thus ;

F(x) = total cost ; x = number of meals consumed

F(x) = 5.60x

Hence, if 3 meals is consumed in a day, the total amount spent would be ;

F(3) = 5.60(3)

F(3) = $16.80

Hence, functions could be helpful in calculating the daily amount expended on food.

A person filing his federal income tax return with the Single filing status had a
taxable income of $31,850. According to the table below, how much of that
income will he have left over after paying his federal income tax?

A) 27,490.00
B) 28,325.00
C) 3525.00
D) 4360.00

Answers

The solution is Option A.

The amount of income left over after paying the federal income tax is given by the equation A = $ 24,490.00

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount of income left over be represented as A

Now , the equation will be

The amount of taxable income is $31,850.00

And , the taxable income is in the range $ 8,350 - $ 33,950

So , the fixed tax for the amount is $ 835.00

The percentage of tax is 15 % of the amount over

So , the amount over = $ 8,350

Substituting the values in the equation , we get

The amount over = $31,850.00 - $ 8,350.00

The amount over = $ 23,500.00

Now , 15 % of amount over = 23,500 x ( 15/100 )

15 % of amount over = $ 3,525.00

And , Total tax = 15 % of amount over + fixed tax for the amount

Total tax = $ 3,525.00 + $ 835.00

Total tax = $ 4,360.00

Now , the amount of income left over A = amount of taxable income - Total tax

Amount of income left over A = $31,850.00 - $ 4,360.00

Amount of income left over A = $ 27,490.00

Therefore , the value of A is $ 27,490.00

Hence , the amount left over is $ 27,490.00

A spinner has 10 equally sized sections, 5 of which are gray and 5 of which are blue. The spinner is spun twice. What is the probability that the first spin lands on gray and the second spin lands on blue? Write your answer as a fraction in the simplest form.

Answers

Answer:

1/4

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur. Mathematically,

Probability = Expected outcome/Total outcome

If the spinner has 10 equally sized sections 5 of which are gray and 5 of which are blue, the total outcome will be equal to 10.

The probability that spinning lands on blue = 5/10

The probability that spinning lands on gray = 5/10

The probability that the first spin lands on gray and the second spin lands on blue is 5/10*5/10 = 25/100

25/100 = 1*25/(4*25) = 1/4

Hence, the probability that the first spin lands on gray and the second spin lands on blue in its simplest form is 1/4

consider the statement p:x+9=10.which of the following is a equivalent statement

Answers

Answer:

The equivalent expression for x+9=10 is x=1.

Step-by-step explanation:

We have a statement i.e. x+9=10

We need to find an equivalent statement for the above statement.

If we subtract 9 on both sides of the above statement,

x+9-9=10-9

We know that, 9-9=0 and 10-9 =1

x+0=1

x=1

So, the equivalent expression for x+9=10 is x=1.

What is the measure of the angle between Elm Street and Pine Avenue? 54° 72° 108° 144°

Answers

Answer:

72°

Step-by-step explanation:

From the information given:

A town planner wants to build two new streets, Elm Street and Garden Road, to connect parallel streets Maple Drive and Pine Avenue.

We are also told that there is a  Trapezoid EFGH with EH as the Pine avenue and EF as the Elm street.

However, side FG and EH are parallel.

∠G = 108°

From the property of parallel lines :

since FG || EH

Then  ∠G = ∠H  = 108°  (i.e corresponding angle will also be equal)

The required angle between Elm Street and Pine Avenue would be interior angles +  180°  given that  alternate angles are also equal.

The required angle between Elm Street and Pine Avenue = 180° - 108°

The required angle between Elm Street and Pine Avenue = 72°

Answers

Answer:

The given graph shows the relationship between the f(x) and g(x).

Since the problem is to find the points where f(x) becomes equal to g(x) then we will be focusing only to the x-axis and ignore the points of y-axis.

Out of the four choices, the correct answer for the given functions of x will be f(2) = g(2) and f(0) = g(0), f(0) and g(0) is located at the origin. So the points where the curve and line are intersecting is at f(2) and g(2) and the other point is at f(0) and g(0), neglecting the y-axis.

Equation for the line parallel to the given that passes through the given point.Solution

The given line has a slope of -3/2

The parallel line will have the same slope

The point-slope form:

y - y1 = m(x -x1)

We have m = -3/2, y1= -2, x1 = 3, plug in:

The point C (4, 4) has been rotated by 180⁰ counter clock wise about the point (1, 3). Determine the coordinates for the point C’.

Answers

Answer:

C'(-3, -1)

Step-by-step explanation:

A transformation is the movement of a point from its initial position to a new position. Types of transformation are reflection, rotation, dilation and translation.

If a point A(x, y) is rotated 180 degrees counterclockwise about the origin the new coordinates is A'(-x, -y)

Since C(4, 4) is rotated about point (1, 3), we have to make point (1, 3) the origin. This means the new origin O' is at (1, 3). The horizontal and vertical distance between the new origin and point C gives the new coordinate of point C. Point C x coordinate is 3 units from the new origin and y coordinate is  1 unit from the new origin, hence the new coordinate of point C is (3, 1).

A 180⁰ counter clock wise rotation of point C would give a new point at C'(-3, -1)

Answers

Answer:

see below

Step-by-step explanation:

Find the slope

m= ( 40.12 - 11.02)/ (400-100)

   = 29.1 / 300

   =.097

We can use the linear form y = mx+b

y =.097x +b

40.12 = .097 ( 400) +b

40.12 = 38.80 +b

1.32 = b

y = 0.097x + b

C(x) = .097x + 1.32

The fixed cost is b = 1.32

C(1001) =   .097(1001) + 1.32

            =98.417

The marginal cost is the cost of adding one more item, which is the slope

.097 is the marginal cost

It means to make one more cup of coffee will cost $.097
