To find this out, turn the percent into a decimal:
45% -----> .45 (Divide by 100)
Then multiply the total minutes by the decimal percent:
1400 x .45 = 630
The final answer is, Maris has used 630 minutes.
Hope this helps!
Answer:
Step-by-step explanation:
Choose some values of x to plot. I usually start with zero:
5×0 + 5 = 5
Plot the point (0,5).
Then use x=-1, because it is the x- intercept:
5×(-1) + 5 = 0
Plot the point (-1,0).
Draw the line through both points.
