Answer:
Step-by-step explanation:
Since there are 4 cities, there are (4-1)! = 6 possible routes. Half of those are the reverse of the other half, so there are 6/2 = 3 different possible routes. All of those are listed among the answer choices, along with their cost. All you need to do is choose the answer with the lowest cost:
ACDBA, $900
__
At $960, the other two routes are higher cost.
Answer:x=3
Step-by-step explanation:Multiply both sides of equation by four. Subtract 56 from the left and move to the right. Calculate 80-56. Divide by 8 on both sides x=3
Answer:
Step-by-step explanation:
<h2>1</h2>
Use similarity ΔPQS ~ ΔRQS
<u>Use the ratio of corresponding sides:</u>
- PS/QS=QS/SR
- PS*SR = QS²
- PS*20 = 8²
- 20PS = 64
- PS = 64/20
- PS = 3.2
<h2>2</h2>
Find PS
- PS = PR - RS = 72 - 54 = 18
Use similarity ΔPQS ~ ΔPRQ
<u>Ratio of corresponding sides:</u>
- PQ/PR=PS/PQ
- PQ² = PR*PS
- PQ² = 72*18 = 4*18*18 = (2*18)² = 36²
- PQ = 36
<h2>3</h2>
Use similarity ΔPQS ~ ΔPRQ
<u>Ratio of corresponding sides:</u>
- PQ/PR=PS/PQ
- PS=PQ²/PR
- PS = 14²/28 = 7
<u>Find RS:</u>
- RS = PR - PS = 28 - 7 = 21
<h2>4</h2>
<u>Answer options</u>
- a) ΔRPQ ~ ΔRQS - correct
- b) ΔRQS ~ ΔQPS - correct
- c) ΔRPQ ~ ΔQPS - correct
- d) ΔRPQ ~ ΔRQS ~ ΔQPS - most correct as combines all above choices
