charlene levington operates an oil change and tune-up service. she charges $33.95 per oil change. 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.
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.
What is an expression?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:-

Step-by-step explanation:
___
|___| combine the rectangle (3 bottom lines, 3 top lines, 2 left lines, 2 right lines)
1/4 divided by 2 3/8
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.
If m ∠ F L G = ( 14 x + 5 ) ° and m ∠ H L G = ( 17 x − 1 ) ° , find m ∠ F L H .
The value of m ∠ F L H is 57°
How to determine the valueFrom 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;
m ∠ F L G = ( 14 x + 5 ) ∠ H L G = ( 17 x − 1 ) °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°

Step-by-step explanation:
What is the equation of a line that has slope of -4/3 and passes through the point (12,-4)
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
Bill has twice as much money as Bob. Paul has $12 more than Bill. Together they have $92. How much money does Bob have?
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.

A line with a slope of -1/12 passes through the point (0, 11). What is its equation in slope-intercept form ?
Answer:
y = -1/12x + 11
Step-by-step explanation:
An ordered pair is the form (x,y) Us the x and y from the point and the slope to find the y intercept and then you can write the equation.
Use o for x and 11 and or y and - 1/12 for m
y = mx + b
11 = (-1/12)(0) + b
11 = b
y = -1/12x + 11
Answer:
Y = -1/12 x + 11
Step-by-step explanation:
Start with point (0,11) slope ( -1/12) form :
(y-11) = -1/12 (x-0)
re-arrange to slope intercept form just by adding 11 to both sides
y = -1/12 x + 11
Triangle HIJ, with vertices H(-9,-8), I(-5,-5), and J(-7,-3), is drawn on the
coordinate grid below.
what is the area, in square units, of triangle HIJ?
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.

Round 1.496 to the place value of the underlined digit.
Rounding off the given decimal to the nearest hundredth, tenth and ones place are 1.50, 1.5 and 2 respectively.
The given decimal number is 1.496.
We need to round off the given decimal number.
How to round off the decimal number?There are some basic rules that need to be followed for rounding numbers.
We first need to know what our rounding digit is. This digit is the one that will ultimately be affected.After this, we need to check the digit to the right of this place which will decide the fate of the rounding digit.If the digit to the right is less than 5, we do not change the rounding digit. However, all the digits to the right of the rounding digit are changed to 0.If the digit to the right is 5 or more than 5, we increase the rounding digit by 1, and all the digits to the right of the rounding digit are changed to 0.Now, rounding off 1.496 to the hundredth place is 1.50
Rounding off 1.496 to the tenth place is 1.5
Rounding off 1.496 to the ones place is 2
Therefore, rounding off the given decimal to the nearest hundredth, tenth and ones place are 1.50, 1.5 and 2 respectively.

Question 10: Andrew is going to fill an empty swimming pool.
Andrew fills the swimming pool with water at a constant
rate of 2.1 litres per second.
Given 1m³= 1000 litres, estimate how long it takes to fill the pool.
7.15m
21m
1.9m
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.

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
