Answer:
How much they make = 20,000
Expenses = 15,000
Profit = 5,000
Step-by-step explanation:
Well this question isn't very clear since it didn't state what the original cost for one iphone is. I think they are assuming one iphone to be 200 dollars or the sold amount, but this information is not directly stated. Anyways....
How much they make 100x200 = 20,000
Expenses 100(200-50) = 15,000
Profit 20,000 - 15,000 = 5,000

Answer:
y= -1/2x
Step-by-step explanation:
Equation of the line is always in the form y=mx + c
where c is the y-intercept ( where the graph crosses the y-axis) and m is the gradient.
The straight line passes through the origin which are the points (0,0) hence
gradient= change in y÷ change in x
G= -2-0 ÷ 4-0 =-2÷4= -1/2x
y= 1/2x+c
-2=-1/2(4)+c
-2=-2+c
-2+2=c
c=0
∴ the equation of the line is y=-1/2x
Final answer:
The equation of the line passing through the origin and the point A(4,-2) is y = -0.5x.
Explanation:
In Mathematics, the equation of the line can be found using the point-slope form which is y = mx + c, where 'm' is the slope of the line and 'c' is the y-intercept. Since the line passes through the origin O(0,0), the y-intercept 'c' is 0. The slope 'm' of the line is found by the formula 'change in y/change in x'. Given the point A(4,-2), the change in y (the difference in the y-values of your two points) is -2 - 0 = -2, and the change in x (the difference in the x-values of your two points) is 4 - 0 = 4. Therefore, the slope 'm' is -2/4 = -0.5.
Substitute 'm' and 'c' values in the equation y = mx + c, we get the equation of the line OA as y = -0.5x.

Answer: 12 hrs 40 mins
Step-by-step explanation:
The swimming time was 1 hour 25 minutes.
Her biking time was 5 hours longer than the swimming time so it was:
= 1 hr 25 mins + 5 hours
= 6 hours 25 mins
Her running time was 4 hrs 50 mins.
Add them all up to find the amount of time ran. First add up the minutes:
= 25 + 25 +50
= 1 hr 40 minutes
Hours = 1 + 6 + 4
= 11 hours
Total:
= 11 + 1 hr 40
= 12 hrs 40 mins

The difference between the greatest and lowest numbers in a piece of data is the range. The range of the given data set {6, 9, 9, 12, 18, 24, 24, 24, 37} is 31.
What is the range?
The difference between the greatest and lowest numbers in a piece of data is the range. The difference here is that the range of a set of data is determined by subtracting the sample maximum and minimum.
The range of the given data set {6, 9, 9, 12, 18, 24, 24, 24, 37} is,
37-6 = 31
Hence, The range of the given data set {6, 9, 9, 12, 18, 24, 24, 24, 37} is 31.
