Joe worked as a waiter at a charity banquet. He earned $17.50 for each hour worked. Joe also received a tip for this event in th
Alenkasestr [34]

Answer:

Joe still owes his dad $121.83

Step-by-step explanation:

Joe's new loan balance after paying his dad = amount he owes his dad - joes profit

Joe's profit from working as a waiter = Revenue - cost of renting a uniform

Revenue = amount earned for total hours worked + tips

total hours worked = 4 hours + 2.5hours = 6.5 hours

amount earned for total hours worked = 6.5 x $17.50 = $113.75

Revenue = $113.75 + $35.80. = $149.55

Joe's profit = $149.55 - $21.38 = $128.17

Loan balance = $250 - 128.17 = $121.83

Alternatively, the equation provided in the question can be used :

250 – 17.5(4 + 2.5) – (35.80 – 21.38)

250 - 113.75 - 14.42

= $121.83

Write and equation in standard form for a line that is (a) parallel (b) perpendicular to the line with an equation of y= 3x - 5
KatRina [158]

Answer:

  (a) 3x -y = 7

  (b) x +3y = 29

Step-by-step explanation:

(a) The standard form of the given line is ...

  3x -y = 5

The parallel line will have a constant on the right that makes it go through (5, 8), so it will be ...

  3x -y = 3(5) -(8)

  3x -y = 7

__

(b) The perpendicular line will have coefficients for x and y swapped and one of them negated. Again, the constant is chosen to make it go through (5, 8).

  x + 3y = (5) +3(8)

  x + 3y = 29

Chloe notices that segment ST and segment VW are congruent in the image below.
IgorLugansk [536]
The SAS similarlity theorem is the type of similarlity that show that two triandles are similar by showing that two of the sides are similar with the angle between the two sides also similar.

Thus, given that <span>segment ST and segment VW are congruent, and also from the image it can be seen that angle S is congruent to angle V.

Thus, to show that </span>ΔSTU ≅ ΔVWX, we have to show that <span>US≅XV.

There</span>fore, the <span>step that could help her determine if ΔSTU ≅ ΔVWX by SAS is<span> US≅XV</span></span>
