The statements and reasons for the proof are:

  1. CN ≅ WN [given]
  2. ∠C ≅ ∠W [given]
  3. m∠CNR ≅ ∠WNO [vertical angles theorem]
  4. ΔCNR ≅ ΔWNO [ASA theorem]
  5. RN = ON [CPCTC]

<h3>What is the CPCTC and ASA Congruence Theorem?</h3>

When two triangles have two corresponding congruent angles and one corresponding included sides that are congruent, both triangles are congruent by ASA. By implication, the CPCTC states that since they are congruent triangles, all its corresponding parts are congruent to each other.

The statement for the proof along with the reasons in bracket are:

  1. CN ≅ WN [given]
  2. ∠C ≅ ∠W [given]
  3. m∠CNR ≅ ∠WNO [vertical angles theorem]
  4. ΔCNR ≅ ΔWNO [ASA theorem]
  5. RN = ON [CPCTC]

A total of 70 tickets were sold for a concert and earn the organizers $804. If the cost of each ticket is either $10 or $12, how
crimeas [40]

Answer:

52 tickets cost $10 and 18 tickets cost $12

Step-by-step explanation:

10x+12y=804. (1)

x+y=70. (2)

From (2)

x=70-y

Substitute x=70-y into (1)

10x+12y=804

10(70-y)+12y=804

700-10y+12y=804

700+2y=804

2y=804-700

2y=104

y=104/2

y=52

Recall

x+y=70

x+52=70

x=70-52

x=18

52 tickets cost $10 and 18 tickets cost $12

What is the volume?<br> 2 mm<br> 8 mm<br> 4 mm<br> cubic millimeters
shutvik [7]

Answer:

64 mm³

Step-by-step explanation:

I am assuming there was a photo to go with this problem

However the general formula to find volume is usually V = l×w×h

  • It does not matter which measurement is which because they all get multiplied together.
  • However assigning a name to each unit of measurement we will denoted the length (l) as 2 mm, the width (w) as 8 mm, and the height (h) as 4 mm
  • Plugging these values into the formula we get: V = (2)(8)(4) = 64 mm³

Two trains leave stations 288 miles apart at the same time and travel towards each other. One train travels at 95 miles per hour
erma4kov [3.2K]
95x=85x+288
You could add 288 to any side, it just shows that they're 288 miles apart.
Let's subtract 85x from both sides.
10x=288
28.8=x
It'll take 28.8 hours for the trains to meet. Let's make sure.
28.8×95
2,736
28.8×85
2,448
2,736-2,448
288
So, they'll meet up after 28.8 miles.
