11.73 plus half a 20% tip ? anyone?

11.73 plus half a 20% tip...so a 10% tip?

There are 2 ways you can do this, you can find the 20% tip, then divide it in half.

11.73 · 0.20 = 2.346

2.346 is you 20% tip, you divide it in half which equals 1.173

11.73 + 1.173 = 12.903

Another way is just finding the 10% tip

11.73 · 0.10 = 1.173

11.73 + 1.173 = 12.903

or you could do:

11.73 · 1.10 = 12.903

You can do whichever way you learned it. Your answer is 12.903, if you round it, it will be 12.90

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

y=sec x is the correct answer
