A waiter at a restaurant receives a 15% tip on a $25 bill. At the same restaurant, a waitress receives a 20% tip on a $20 bill.
Sophie [7]

Answer:

The waitress who received 20% of $20 gets a larger tip.

The waitress who received 20% of $20 gets $4.00 tip, and the waitress who received 15% of $25 gets a tip of $3.75

Step-by-step explanation:

To get 15% of 25, you multiply it by .15, giving you your answer.

To get 20% of 20, you multiple it by .20, giving you your answer.

PLZ PLZ HELP!!!!!! The expression cos(A+pi) - sin(A + pi) can be simplified to
artcher [175]
Sin(A+B) = SinACosB + CosASinB
Cos(A+B) = CosACosB - SinASinB

Note pi is taken as pi radians = 180 degrees.    Cospi = Cos180 = -1.
                                                                                       Sinpi  = Sin 180 = 0

Cos(A+pi) = CosACospi - SinASinpi =  (CosA) * (-1) - (SinA) *(0) = -CosA.
Sin(A+pi) = SinACospi + CosASinpi  =  (SinA)* (-1) + (CosA) * (0) = -SinA.

Cos(A+pi) - Sin(A+pi) = -CosA - -SinA = -CosA + SinA = SinA  - CosA.

Answer = (a).

Please help me with the below question.
tresset_1 [31]

We have the following three conclusions about the <em>piecewise</em> function evaluated at x = 14.75:

  1. \lim_{t \to 14.75^{-}} f(t) = 66.
  2. \lim_{t \to 14.75^{+}} f(t) = 10.
  3. \lim_{t \to 14.75} f(t) does not exist as \lim_{t \to 14.75^{-}} f(t) \ne  \lim_{t \to 14.75^{+}} f(t).

<h3>How to determinate the limit in a piecewise function</h3>

In a <em>piecewise</em> function, the limit for a given value exists when the two <em>lateral</em> limits are the same and, thus, continuity is guaranteed. Otherwise, the limit does not exist.  

According to the definition of <em>lateral</em> limit and by observing carefully the figure, we have the following conclusions:

  1. \lim_{t \to 14.75^{-}} f(t) = 66.
  2. \lim_{t \to 14.75^{+}} f(t) = 10.
  3. \lim_{t \to 14.75} f(t) does not exist as \lim_{t \to 14.75^{-}} f(t) \ne  \lim_{t \to 14.75^{+}} f(t).

Harry used 84% of the money in his savings account to buy a used dirt bike that cost him $1,050. How much money is left in Harry
alexira [117]
So 84%=1050
what is left is 100%-84%=16%
equal ratios
1050 to 84=x to 16
1050:84=x:16
fractionify
1050/84=x/16
multiply both sides
by 16
16800/84=x
simplify
200=x
answer is 200 is left
