Answer:
w = 11/24
Step-by-step explanation:
11/24 + w = 11/12
w = 11/12 - 11/24
LCM of 12 and 24 is = 24
divide the denominators of both fractions by the LCM(24) and then multiply the results with the numerators
so we have w = 22 - 11 /24
w = 11/24
Answer:
1.4 hours or 83 minutes
Step-by-step explanation:
90 mi / 65 mph = 1.4 hr
the position of the triangle changes
Total distance around a shape
Answer:
(B)15,36,39
Step-by-step explanation:
To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.
By Pythagoras Theorem: 
In 15,30,35

In 15,36,39

In 15, 20, 29

In 5,15,30

We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.
