15 The Kellys are having dinner at a local restaurant. Mr. Kelly wants to give the server a 15% gratuity, and the sales tax is 6.5%. He will use the amount of the bill to find each additional amount. Part A Which components would Mr. Kelly use to write an equation to determine the total cost of the meal, given the amount of the bill, x? Select all the components of the equation. AX D x + 0.65 B) x + 0.15 E) 0.65x C 0.15x F 0.065x Part B By what percent does the cost of the meal increase with t ax and gratuity?

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

i think the answer is b. i hope i !
