Answer:
4 hours
Step-by-step explanation:
The general formula for distance, rate and time is:
d = rt, where distance is the product of rate multiplied by time
Given that one train is moving at a rate of 70 mph and one is moving at a rate of 62 mph in the opposite direction, the combined distance over time is equal to 528 miles. Using the variable 't' for time:
70t + 62t = 528
Combine like terms: 132t = 528
Divide both sides by 132: 132t/132 = 528/132 or t = 4 hours
X= balance
x+45+18+27-21-93 = x - 24

Answer: 600 m/s^2
Step-by-step explanation:
Use the first kinematic equation
Answer:
x-intercept = -6 y-intercept = 9
Step-by-step explanation:
Surface area = 50 x 30 = 150
Per cm of height 150 cubic cm needed
7cm height needed
150 x 7 = 1050 cubic cm needed
