A company rents out 15 food booths and 25 game booths at the county fair. The fee for a food booth is $100 plus $3 per day. The
mash [69]

Answer:

2,750+170d

Step-by-step explanation:

Calculation to Enter and simplify an expression for the amount in dollars that the company is paid

First step

Let d represent numbers of day

15(100+3d)

Second step is the Expression for the food booths

25(50+5d)

Third step is Expression for the game booths

15(100+3d)+25(50+5d)

Fourth step is the Expression for both game and food booths

15*100+15*3d+25*50+25*5d

=1,500+45d+1,250+125d

Fifth step is to make use of distributive Property

1,500+1,250+45d+125d

Last step is to make use of cumulative property

(1,500+1,250)+(45d+125d)

=2,750+170d (combine like terms)

Therefore expression for the amount in dollars that the company is paid is 2,750+170d

Use the proof diagram to complete the question. State the missing reason in this proof for the letter given.
Hatshy [7]

Answer:

See below.

Step-by-step explanation:

We know that \angle 1\cong\angle 5 and we want to prove that p\parallel r.

  Statements                                         Reasons

1) \angle 1\cong \angle 5                                               Given

2) \angle 4\cong \angle 1                                              A) Vertical Angles Are Congruent

3) \angle 4\cong \angle5                                             B) Substitution Property

4) p\parallel r                                                   C) Alternate Interior Angles Converse*

*We know that alternate interior angles are congruent when two parallel lines are cut by a transversal. So, the converse states that if the two alternate interior angles are congruent, the the two lines must be parallel.

Further Notes:

I'm not sure why they did more than necessary. Since \angle 1\cong \angle 5, they are corresponding angles. Then by the Corresponding Angles Converse, p must be parallel to r.
