Answer:
A 20 percent tip is basically multiplying the price by 0.2
Percent means out of a hundred.
20/100 is 0.2
We have to find 0.2 of 15.
We can multiply 15 by 0.2 to find 20 percent of 15 and you would get 3.
20 percent of 15 is 3 dollars thats your answer to A
Now the total price would just be the percentage you found in A and add it to the total breakfast.
3 + 15 = 18

Answer:
Determine whether lines are parallel or perpendicular given their equations; Find equations of . We can begin by using point-slope form of an equation for a line. No. For two perpendicular linear functions, the product of their slopes is –1.
Step-by-step explanation:
For this case we have the following equation:
y = 100 - 8.9x
Where,
x = the number of hours of use
For 11 hours of use we have x = 11.
Substituting:
y = 100 - 8.9 * (11)
y = 2.1%
Answer:
the best prediction of the percent of remaining power for a battery after 11 hours of use is:
y = 2.1%
