It takes her (100 mi)/(50 mi/h) = 2 h to get to her destination. She has 1 h 40 min = 100 min for her 100 mi return trip.
.. (100 mi)/(100 min) = (60 mi)/(60 min) = 60 mi/h
She must return at the rate of 60 mph to complete the trip in 3 h 40 min.
Answer:
90 meters
Step-by-step explanation:
From the question we are to calculate the distance that the slug can move in 60 minutes.
From the question, we know that:
20 minutes = 30 meters
60 minutes = x meters
Cross Multiply
20 minutes × x meters = 30 meters × 60 minutes
x meters = 30 meters × 60 minutes/20 minutes
x meters = 90 meters
Answer:
74 and 79
6
Step-by-step explanation:
Two solutions were found :
z =(2-√-116)/-20=1/-10+i/10√ 29 = -0.1000-0.5385i
z =(2+√-116)/-20=1/-10-i/10√ 29 = -0.1000+0.5385i
Step-by-step explanation:
You find the mean absolute deviation by first finding the mean, and then subtracting all the values in the data set from that, creating a new data set, and then you find the mean of this new data set.
Example:
3, 2, 5, 9, 4
Mean(add them all, divide by how many there are): (3 + 2 + 5 + 9 + 4)/5 = 4.6
Subtract 4.6 from/to all the values:
4.6 - 3 = 1.6
4.6 - 2 = 2.6
5 - 4.6 = 0.4
9 - 4.6 = 4.4
4.6 - 4 = 0.6
Find the mean of these values:
(1.6 + 2.6 + 0.4 + 4.4 + 0.6)/5 = 1.92
So the mean absolute deviation is 1.92.
