What are the numbers to the problem?
Answer:
12.5%
Step-by-step explanation:
I think it's 2 days converted to hours to get 48hrs
6/48×100 to make it a percentage
Answer would be 12.5%
Well that's according to my thinking
Answer: option 2 is the cheapest
Step-by-step explanation:
Option 1 :
10% of 4.99 = 0.499
10% off 4.99 =
4.99 - 0.499 = 4.491
10% of 15.99 = 1.599
10% off 15.99 =
15.99 - 1.599 = 14.391
10% of 30.99 = 3.099
10% off 30.99=
30.99 - 3.099 = 27.891
Total = 4.491 + 14.391 + 27.891 = 46.773
Option 2 :
Most expensive item = 30.99
20% of 30.99 = 6.198
20% off 30.99=
30.99 - 6.198 = 24.792
Total = 24.792 + 15.99 + 4.99 = 45.772
Therefore, option 2 is cheaper by 1.001.
Hope this helped :)
First find the secant line. The slope of the secant line through
(when
) and
(when
) is the average rate of change of
over the interval
![[-1,2]](https://tex.z-dn.net/?f=%5B-1%2C2%5D)
:
The tangent line to
will have a slope determined by the derivative:
Both the secant and tangent will have the same slope when
, or when
.
Sin30= x/18
•18 •18
18sin(30)=x
