Answer:
The answer to your question is 166 mi/h
Step-by-step explanation:
Data
ve = rate eastbound train
vw = rate westbound train = ve - 14
distance = d = 900 mi
time = t = 5 h
Formula
v = 
Substitution and simplification
Now, substitute this value in the equation of vw
vw = 180 - 14
Result
vw = 166 mi/h
Answer: 4 and 7/12
Step-by-step explanation: To add mixed numbers, first add the fractions. To add unlike fractions such as 2/8 + 1/3, first find a common denominator. The common denominator of 8 and 3 is simply the least common multiple of 8 and 3 which is 24.
To get 24 in the denominator of 2/8, we multiply the numerator and denominator by 3 to get the equivalent fraction 6/24.
To get 24 in the denominator of 1/3, we multiply the numerator and denominator by 8 to get the equivalent fraction 8/24.
Now, we have to deal with adding mixed numbers. To add mixed numbers, we will first need to add the fractions. In this case, we have 6/24 + 8/24 which is 14/24.
Now, we have to add the whole numbers. In this case, we have 3 + 1 which gives us 4. Notice that we can reduce our fraction by dividing both the numerator and denominator by 2 to get 7/12.
Therefore, our answer is 4 and 7/12.
Answer:
4 seconds.
Step-by-step explanation:
The function f(x)=-10(x)(x-4) ........ (1), represents the approximate height of a projectile launch on the ground into the air as a function of time in seconds x.
Now, we are asked that for how long from the launch does the projectile stays in the air.
Therefore, we have to solve the equation (1) making f(x) as zero.
Hence, 10x(x - 4) = 0
⇒ x = 0 or x = 4
(As x can not be zero since at x = 0 sec, the projectile was at the ground.}
Hence, x = 4 seconds.
Therefore, the projectile was in the air for 4 seconds. (Answer)
