Answer:
2
Step-by-step explanation:
negative numbers dividing with negative have positive quotients
(red, green) add up to 7 = (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6, 1)
(red, green) add up to 11 = (5, 6), (6, 5)
P(add up to either 7 or 11) = 8/36 = 2/9
Answer:
25
Step-by-step explanation:
Since y varies inversely with x, the relation between y and x will be:
Introducing the proportionality constant, we can write:
Using the first set of given values of x and y, we get:
This means, the relation between y and x is:
We have to find y if x = 20. Using this value in above equation, we get:
Thus y would be 25 if x is 20.
Total time (1 2/3 hours) minus the time spent stretching (1/4 hour) minus the time spent showering (1/3 hour) equals the time spent running.
x= time spent running
x= 1 2/3 - (1/4 + 1/3)
change 1 2/3 to improper fraction
x= 5/3 - (1/4 + 1/3)
need to multiply by a common factor
3 and 4 go into 12 evenly
5/3= 20/12
1/4= 3/12
1/3= 4/12
x= 20/12 - (3/12 + 4/12)
x= 20/12 - 7/12
x= 13/12
change back to mixed fraction
x= 1 1/12 hours spent running
Hope this helps! :)
