Answer:
The equation representing the total distance would be A. 105x + 90.
The time the truck has travelled would be 8 hours while the time traveled by the train would be 6 hours.
Step-by-step explanation:
Firstly, let's set the time travelled by the train to be x hours.
According to the question, the equation would be 45(x + 2) = 60x, because the truck has travelled 2 more hours than the train.
Hence:
Therefore, the truck has travelled a total of (6 + 2) hours = 8 hours, and the train has travelled for 6 hours.
Also, the equation can be found by adding both equations up:

Answer:
Step-by-step explanation:
equation of the circle (x - 4)² + (y - 1)² = 9
Length of the vertical leg comes from subtracting the y values of (4, 1) and (4, 3) 3 - 1 = 2
Horizontal leg = √(3² - 2²) = √5
Roughly 95% of the data lies within 2 standard deviations of the mean.
So (100% - 95%)/2 = 2.5% of the data lies within each tail.
This means roughly 2.5% of the data is in the left hand tail.
Answer:
The cost is $100.80
Step-by-step explanation:
100% = $140
72% = sale price
140 x 0.72 = $100.80
