horrorfan [7]

Answer:

If Luca wants to leave a 16% tip on the total amount including the tax, he should pay $32.24.

Step-by-step explanation:

First, you have to calculate the 4% of the bill and add that amount to the total of the bill to determine the total amount including the tax:

193.75¨*4%=7.75

193.75+7.75=201.5

Now, you have to calculate 16% of the amount including the tax:

201.5*16%=32.24

According to this, the answer is that if Luca wants to leave a 16% tip on the total amount including the tax, he should pay $32.24.

A rational expression is undefined whenever its numerator is zero.
kipiarov [429]

Answer:

False

Step-by-step explanation:

for a rational number expressed as (A / B) where A & B are integers

if the numerator (A) is zero, then (A/B) is simplify zero

i.e (A / B) = (0 / B) = 0

however if the denominator (B) is zero, then by definition any value divided by zero is undefined.

(A / B) = (A / 0) = {undefined}

For each triangle shown below, determine whether you would use the Law of Sines or Law of Cosines to find angle x. Then find ang
GalinKa [24]
For the question above we can use the law of sine that states;

a/sinA = b/sinB = c/sinC
 Where a is the opposite side of angle A
             b is the opposite side of angle B
             c is the opposite side of angle C

x/sin63 = 65/sin40

x = 65(sin63)/sin40

   = 57.9154/0.6429
     = 90.10

The answer is <span>A) 90.1 by The Law of Sines (SAS)</span>
