You want to leave a 15% tip on a meal that cost $15.77.
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $15.77 meal cost is.This is always done by multiplying 0.15 by $15.77, or
0.15 x $15.77=$2.37.
So, the amount of tip you are going to leave is $2.37.
This makes the total cost of your meal (to write on your charge slip or other payment)
$15.77 + $2.37 = $18.14
$18.14 is your answer
The area of the surface given by 
is 1. In terms of a surface integral, we have
By multiplying each component in 
by 5, we have
and the same goes for the derivative with respect to 
. Then the area of the surface given by 
is
550×10 I think how do you want it to be explained
(6, 2 )
substitute x = 5 into the equation and solve for y
6y + 8 = 20 ( subtract 8 from both sides )
6y = 12 ( divide both sides by 6 )
y = 
= 2
the ordered pair is (5, 2 )
12/2+4-2*3
According to the order of operations, evaluate division and multiplication first.
6+4-6
Then add and subtract from left to right
10-6
4
Final answer: A
