Answer:
300kg
Step-by-step explanation:
240(25/100)
240(.25) = 60
25% of 240 = 60, so add that 60 to get an extra 25% for this month
240 + 60 = 300
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:-

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

What error did the student make and what is the correct value
of x?
Answer:
x=5
Step-by-step explanation:
step 1 : exapnding 2(x+4) will give you 2x +8 , the student made an error in expanding
so it should then be 2x+8 = 6x-12
and then if you move the letters to one side and the numbers to the other you will get :
-4x = -20
x=5
hope this works :)
x=5
Step-by-step explanation:
the student added a minus in 2x and 8 when it's suppose to be an addition that is the error
2(x+4)=6(x-2)
2x+8=6x-12
2x-6x=-8-12

select the points you need to calculate the average rate of change from the beginning of the slide to when the slide has covered a horizontal distance of 15 feet. (0, 80) (5, 40) (10, 20) (15, 10) the average rate of change is .
The typical pace of change since the slide's start, -14/3.
Let, the average rate of change is k
(x1,y1) (x2,y2), k= (y2-y1)/(x2-x1)
=10-80/15
=-70/15
k=-14/3
Average = -14/3
How do you find average rate?Divide the change in y-values by the change in x-values to determine the average rate of change. Identifying changes in measurable parameters like average speed or average velocity calls for the knowledge of the average rate of change.
The average rate of change is a measure of how quickly on average one quantity changes in relation to another. It provides a general sense of the function's change in value per unit throughout the specified time period. Simply said, the rate of change is calculated by dividing the amount of change in one item by the equal amount of change in another. Let's take a closer look at the average rate of change formula.

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.

From the given linear function, it is found that each descent by 88 meters was 11 seconds long.
What is the missing information?
The graph of the linear function is missing, and it is given at the end of the answer.
A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points on the graph, the slope is given by change in y divided by change in x. For this problem, the points are given as follows:
(0, 440) and (40,0).
Hence the slope is:
m = (0 - 440)/(40 - 0) = -11.
Meaning that in each minute, he descended 8 meters. Thus the time to descend 88 meters is given by:
t = 88/8 = 11 seconds.

there are four even integers in the top five rows of pascal's triangle. how many even integers are in the top 10 rows of the triangle?
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.

Step-by-step explanation:
Use the position equation given below, where s represents the height of the object (in feet),
v0
represents the initial velocity of the object (in feet per second),
s0
represents the initial height of the object (in feet), and t represents the time (in seconds), as the model for the problem.
s = −16t2 + v0t + s0
You drop a coin from the top of a building. The building has a height of 1028 feet.
(a) Use the position equation to write a mathematical model for the height of the coin.
s = ?
(b) Find the height of the coin after 1.5 seconds.
s = ? ft
(c) How long does it take the coin to strike the ground? (Round your answer to two decimal places.)
t = ? sec
(I really can't comprehend how to due this but its due soon, please help me!)
Using the motion equation we can get:
a) s = -16*t^2 + 1028
b) 992 feet above the ground.
c) after 8 seconds, the coin will hit the ground.
How to write the height equation?
First, we know that the general height equation is:
s = -16*t^2 + v0*t + s0
In this case, the coin is dropped, so the initial velocity v0 is zero.
And the coin is dropped from a height of 1028 ft, then s0 = 1028
Replacing that in the equation we get:
s = -16*t^2 + 1028
b) The height after 1.5 seconds is what we get by evaluating the height equation in t = 1.5
s = -16*(1.5)^2 + 1028 = 992
This means that the height after 1.5 seconds is 992 ft above the ground.
c) The coin will strike the ground when s = 0, then we need to solve:
s = 0 = -16*(t)^2 + 1028
Solving that for t, w eget:
16*t^2 = 1028
t^2 = 1028/16
t = √(1028/16) = 8
This means that the coin will hit the ground after 8 seconds.

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.
