The profit that Jim got in percentage will be 46.67%.
What is a profit?A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.
The profit is given as,
Profit = Selling price - Cost price
Jim buys a wardrobe for £30. He sells it for £44. The profit is calculated as,
Profit = £44 - £30
Profit = £14
The profit in percentage is calculated as,
P = (£14 / £30) x 100
P = 0.4667 x 100
P = 46.67%

Mallory wants to buy a new window air conditioning unit. The cost for the unit is $329.99. If she plans to run the unit three months out of the year for an annual operating cost of $108.78, which function models the cost per year over the lifetime of the unit, C(n), in terms of the number of years, n, that she owns the air conditioner?
The function (329.99 + 108.78n)/n will represent the cost per year over the lifetime of the unit in terms of the number of years.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
Cost for the unit = $329.99
Annual operating cost = $108.78
C(n) represents the cost per year
n represents the number of years
The function can be modelled:
C(n) = (329.99 + 108.78n)/n
Thus, the function (329.99 + 108.78n)/n will represent the cost per year over the lifetime of the unit in terms of the number of years.

Raymond swam 236 meters in 6 minutes. At this rate, how many meters can he swim in 15 minutes? A. 94.4 OB. 767 OC. 590
263 meters in 6 mins
to find:how many meters can he swim in 15 minutes.
solution:[tex] \frac{236}{6} [/tex]
[tex] = 39.33[/tex]
[tex]39 .33\times 15[/tex]
[tex] = 589.95[/tex]
[tex]nearest \: whole \: number = 590[/tex]
therefore, he can swim 590 meters in 15 minutes.
answer= option C
Answer:
C: 590 meters
Step-by-step explanation:
Let's start by finding Raymond's rate of swimming for meters per minute. We know that he can swim 236 meters in 6 minutes. So let's divide 236 by 6 to find how far Raymond can swim in 1 minute.
236 / 6 = 39.3
So if we know Raymond can swim 39.3 meters in 1 minute, we multiply 39.3 meters by 15, to find how far he can swim in 15 minutes.
39.3 * 15 = 589.995 which is approximately 590 meters. So, we would chose option C: 590.
The scatter plot shows the profit by the month for a new company during its first year of operation. Which equation most closely models the line of best fit for the scatter plot? A) y = 5x B) y = 2.5x C) y = 5x + 1000 D) y = 2.5x + 1000
The equation most closely models the line of best fit for the scatter plot is y = 2.5x
Equation of a line
A line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b
where:
m is the slope or rate of change
b is the intercept
Using the coordinate points on the line (3, 5000) and (9, 20000)
Get the rate change(slope)
Slope = 20000-5000/9-3
Slope = 15000/6 = 2500
Determine the y-intercept by substituting
5000 = 2500(3) + b
b = 5000 - 7500
b = -2500
Determine the equation
y = 2.5x - 2.5
Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x

Step-by-step explanation:
SF: 2{(8 x 4) + (4 x 15) + (8 x 15)}
therefore: 2 [32 + 60 + 120]
therefore: 64 + 120 + 240
therefore: 360 + 64
therefore: 424
Answer:
424
Step-by-step explanation:
To find the surface area, you need to find the area of all the faces of the shape. Because this is a rectangle, you only need to find the 3 different faces and then multiply them by 2. For the largest face, the dimensions are 8*15, which is 120. Multiply that by 2 and you get 240. For the long, slim face, the dimensions are 4*15, which is 60. Multiply that by 2 and you get 120. Finally, the smallest face's dimensions is 8*4, which is 32. Double that and you get 64. Now all you need to do is add all the products up. 240+120+64 is 424, which is your answer.

The value of multiplying the factors of 3√2 * 2√5 * 8√18 is 288√5 in radical form
How to multiply the expression?The expression is given as:
3√2 * 2√5 * 8√18
Multiply the integers
3√2 * 2√5 * 8√18 = 3 * 2 * 8 *√2 *√5 * √18
