The charges for a week in which Charlene's facility did 35 oil changes and tuned 5 four-cylinder engines, and 7 six-cylinder will be $2313.25.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that charges per oil change are $33.95, charges for a four-cylinder engine $72.50, charges for a six-cylinder engine $82.50, and, charges for an eight-cylinder engine $92.50.

The total charges will be calculated as below:-

No oil changes done by Charlene = 35

price of 5 - four-cylinder engines = 5 × 72.50

= 362.50                                .....(1)

Price of 7 - six cylinder engines = 7 × 82.50

= 577.50                                ........(2)

Price of 2 - eight-cylinder engines = 2 × 92.50

= 185                                       ...........(3)

Now, adding (1), (2),(3)

= 362.50 + 577.50 + 185

= 1125                                        ...........(4)

Total charges for oil = 33.95 × 35

= 1188.25                                  ..........(5)

Add equations (4) and (5) to get the total charges.

= 1125 + 1188.25

= 2313.25

Therefore, the total charges will be $2313.25.

The complete question is given below:-

Charlene operates an oil change and tune-up service. she charges $33.95 per oil change. a tune-up is $72.50 for a four-cylinder engine, $82.50 for a six-cylinder engine, and $92.50 for an eight-cylinder engine. what are the charges for a week in which Charlene's facility did 35 oil changes and tuned 5 four-cylinder engines, and 7 six-cylinder?

The line with a slope of [tex]2[/tex] is parallel to the other line of slope [tex]2\![/tex] since the two lines have the same slope.

Step-by-step explanation:

Two lines in a cartesian plane are parallel to one another if and only if their slopes are equal. Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is [tex](-1)[/tex].

For example, a line with a slope of [tex]m[/tex] is parallel to another line of the same slope, [tex]m\![/tex].

Answer:

2/19

Step-by-step explanation:

Rewrite the mixed number as an improper fraction. Frist, multiply 2x8 then add that to 3 to get 19/8. Now you have 1/4 / 19/8. Multiply by the reciprocal of the denominator. Now you have 1/4 x 8/19. 1 x 8 = 8. 4 × 19= 76. This gives you 8/76. You can simplify this by dividing the numerator and denominator by 4. This would give you 2/19.

Step-by-step explanation:

The area of triangle HIJ is 7 square units.

Given that, the vertices of triangle HIJ are H(-9,-8), I(-5,-5), and J(-7,-3) respectively. By using the vertices of triangle HIJ we have to evaluate its area in square units. So, let's procced to solve the question.

Area of ΔHIJ = 1/2|x₁(y₂-y₃)+x₂(y₃-y₁)+x₃(y₁-y₂)|

So, x₁ = -9, x₂ = -5, x₃ = -7 and y₁ = -8, y₂ = -5, y₃ = -3

Put all the listed values in the formula of area of triangle HIJ.

By using the above formula, we get

=1/2|-9(-5+3)+(-5)(-3+8)+(-7)(-8-(-5))|

=1/2|-9(-2)-5(5)+(-7)(-3)|

=1/2|18-25+21|

=1/2|14|

= 1/2 x 14

= 7

Therefore, the area of triangle HIJ is 7 square units.

The swimming pool will take 135850 seconds to fill with water.

Given the dimensions of the pool are:

7.15 m

21 m

1.9

The swimming pool is being filled with water at a constant rate of 2.1 liters per second.

hence the volume of the swimming pool is :

volume = 7.15 × 21 × 1.9

volume = 285.285 m³

convert from meters to liters.

volume = 285.285 × 1000

= 285285 liters.

to find out the time required to fill the pool, we need to divide the volume by the flow rate.

⇒ 285285 ÷ 2.1

= 135850

hence the swimming pool will take 135850 seconds to fill with water.

Answer:

$16

Step-by-step explanation:

Let x =  how much money Bob has. (x)

Bob has twice as much money as Bob. (2x)

Paul has $12 more than Bill. (2x+12)

To find out how much money Bob has, we can add our expressions for each person and set them equal to 92.

x + 2x + 2x + 12 = 92

To simplify this equation, we first need to find the like terms and add them.

1x + 2x + 2x = 5x

5x + 12 = 92

Now that we have done that, we can find how much money Bob has by solving for x. First, we subtract 12 on both sides of the equation.

5x + 12 - 12 = 92 - 12

5x = 80

Then we divided by 5 on both sides of the equation.

5x/5 = 80/5

x = 16

Since x = 16, we know that Bob has 16 dollars.

The Excel DATE/TIME capabilities include the TIME Function. We can construct a time using distinct hour, minute, and second components with the aid of TIME.

We might want to date a report while performing financial analysis. In these circumstances, TIME can be used to transform a text string into a format that indicates the time in decimal form. Additionally, the function can be used to combine different values into a single time value.

formula= TIME (hour, minute, second)

distance = rate X time

D = RT

T = D/R

20 feet per second = 1200 feet per minute

16 feet per second = 960 feet per minute

[of minutes to flowerbed] + 14 minutes + [of minutes back to hive] = 19 minutes

(D/R) + 14 + (D/R) = 19

(D/R) + 14 + (D/R) = 19

(D/1200) + 14 + (D/960) = 19, This is the equation we can use to find the distance from the flowerbed to the​ hive.

(D/1200) + (D/960) = 5

(D(1200)(960))/1200 + (D(1200)(960))/960 = 5(1200)960

960D + 1200D = 5(1200)960

2,160D = 5,760,000

There are 22 even numbers in the top 10 rows.

Pascal's triangle is the triangular array of numbers that begins with 1 on the top and with 1's running down the two sides of a triangle.

The tip of the triangle starts with 1 and the 1 starts continuing to both the ends of the triangle in each row and in between there is the sum.

For example:

                  1

                1   1

             1    2   1

         1   3    3     1

In the above manner, it continues.

now, for 10 rows the pascal triangle will be:

                       1

                     1   1

                  1    2   1

              1   3    3     1

          1   4    6      4      1

      1     5   10    10    5     1  

    1    6    15   20   15    6    1

  1    7    21    35   35  21    7    1

1   8     28   56   70   56   28   8  1

1   9   36    84   126  126   84  36 9  1

for five rows in the top, the even numbers are 2, 4, 6, 4 which are 4 in total.

for 10 rows in the top, the numbers are 2, 4, 6, 4, 10, 10, 6, 20, 6, 8, 28, 56, 70, 56, 28, 8, 36, 84, 126, 126, 84, 36

evaluating a function means finding the value of f(x) or f(y).......

Answer:

replace all the x variables with whatever x has been assigned

Step-by-step explanation:

evaluating a function means finding the value of f (x) = or y equals that corresponds to a given value of x to do this simply replace all the x variables with whatever x has been assigned for example if we are asked to evaluate f (4) then x has been assigned the value of 4

Functions are expressed by writing a variable in terms of other variables known as the independent. The derivative of the given function is -3/(x-2)².

Given the function below;

f(x) = 3/x-2

Since it is a quotient, we can use the quotient rule to express the equation as shown:

let u = 3 and v = x -2

du/dx = 0 and dv/dx = 1

According to the rule;

dy/dx = (x-2)(0) - 3(1)/(x-2)²

dy/dx = 0-3/(x-2)²

dy/dx = -3/(x-2)²

Hence the derivative of the given function is -3/(x-2)²

Answer:

y = -4/3x + 12

Step-by-step explanation:

y - y1 = m (x - x1)

the y1 and x1 are where your coordinates go. The m is the slope.

So now we just plug it in.

y - (-4) = -4/3 (x - 12)

we can clean it up some more to make it into the y = mx + b format.

y + 4 = -4/3x - (-4/3)12

y + 4 = -4/3x + 16

y = -4/3x + 12

Answer: 32, but I'm not sure

Step-by-step explanation:

The value of m ∠ F L H is 57°

From the information given, we have that

m ∠ F L G and m ∠ H L G are congruent angles

Note that congruent angles are angles are equal or equivalent to each other

Given that;

Equate the expression for both angles

14x + 5 = 17 x − 1

collect like terms

14x - 17x = -1 - 5

Subtract like terms

-3x = -6

Make 'x' the subject of formula

-3x/-3 = -6/-3

x = 2

But we know that;

m ∠ F L G = ( 14 x + 5 ) = 14(2) + 5 = 28 + 5= 33°

m ∠ F L H = 90 - 33 = 57°

Thus, the value of m ∠ F L H is 57°
