Answer:
$10.52 tip should be given to the waiter.. The total bill including tax is $67.33
Step-by-step explanation:
We are given the following in the question:
Pre-tax amount = $52.60
Tip percentage = 20%
Tax percentage = 8$
Tip value =
Thus, $10.52 tip should be given to the waiter.
Tax value =
Total bill =
Pre tax amount + Tip + Tax
Thus, the total bill including tax is $67.33

Can you mark me as branliest please!!
Answer:
Step-by-step explanation:
slope of reqd. line=-1/4
eq' of line with this slope and passing through (1,1) is
y-1=-(1/4)(x-1)
y=-1/4 x+1+1/4
y=-1/4 x+5/4
3. First factor as a difference of cubes:
For the remaining group, apply the double angle identity.
5. seems rather tricky. You might want to post another question for that problem alone...
6. Factorize the left side as a sum of cubes:
From here we have to prove that
We can write everything in terms of sine:
(double angle identity)
(angle sum identity)
After some simplifying, we're left with showing that
or
This last equality follows from what you could the triple angle identity for sine,
D=diameter, r= radius, c= circumference, A= area
d= 8m
r= d/2
= 8m/2
r= 4m
c= d x 3.14
= 8m x 3.14
c= 25.12m
A=r^2 x 3.14
= (4m)^2 x 3.14
= 16m2 x 3.14
A= 50.24m2
