There are 12 parts to the ratio (1 + 3 + 8 = 12).
Divide 54,000 by 12.
54,000/12 = 4,500
Now multiply for each part:
1 = 4,500
3 = 13,500
8 = 36,000
You can check by adding them up (4,500 + 13,500 + 36,000 = 54,000).
So the ratio is 4,500:13,000:36,000
Hope this helps =)
Area of a triange = 180 degrees
60 + 90 + 30= 180
180-30=150

Answer: -4v+9
Step-by-step explanation:
u - 5 = -4(v - 1)

u = -4v + 9
60 min = 1 hour
1st we need to know how many times 20 goes in 60 so we will divide.
60 ÷ 20 = 3
Now we will multiply to find the trains speed in miles per hour.
3 × 25 = 75
SO, the train travels 75 miles per hour.
Hope I helped ya!!
