Answer:
You must wait 60 minutes for all three lines to arrive at Union Station at the same time again.
Step-by-step explanation:
The complete question in the attached figure
Step 1
Find the least common multiple (LCM) of the three numbers
List the prime factors of each number
Multiply each factor the greatest number of times it occurs in any of the numbers to find out the LCM
The LCM is equal to
therefore
You must wait 60 minutes for all three lines to arrive at Union Station at the same time again.
Answer:
x = 60°
Step-by-step explanation:
First find <E by applying the angles of intersecting chords theorem.
Based on the theorem, we would have the following equation:
m<E = ½(arc CA + arc BD)
Substitute
m<E = ½(170° + 70°)
m<E = ½(240)
m<E = 120°
Let's find x:
x = 180° - m<E (supplementary angles)
x = 180° - 120° (substitution)
x = 60°
3 3/5 - 2/3
1-you convert 3 3/5 to an improper fraction (18/5)
2-then you find a common denominator between then (15)
3-then subtract
your answer would be 49/15
The car was towed for 48 miles.
Step-by-step explanation:
Given,
Amount charges by Acme towing = $30
Per mile charges = $3
Total charged = $174
Let, x be the number of miles.
Towing charges + Per mile charges*number of miles = Total charged
30+3x=174
Subtracting 30 from both sides
Dividing both sides by 3
The car was towed for 48 miles.
