Total time taken by Sam before Al caught up with him = 15+10 = 25 minutes
In hours = 25 minutes = 25/60 = 5/12 hrs
Distance covered by Sam = Distance covered by Al = Speed (Sam) * time taken = 3.2*5/12 = 4/3 miles.
Al takes 10 minutes to cover that distance. Therefore,
Al's speed = Distance/time = (4/3)/(10/60) = (4/3)*(60/10) = 8 mph
3*2 is 6
6/(1/2) is 12
Therefore, the answer is 12
Answer:
acute
Step-by-step explanation:
process of elimination its not a straight line
angle shown is inside the lines
less than 90° so can't be a right angle
Unsure of what you mean by "6-23." There's no subtraction in this problem.
If you meant "6/23," then "doubling" that results in 12/23 cups. Still, that does not look right. Go back and ensure that you have copied down the original problem exactly.
Answers:
C, D, E
Step-by-step explanation:
A rational number is a integer. It is also a terminating or repeating decimal.
A rational number can be written as a fraction of two integers.
Answer A is not correct because it's decimal never ends. It is also not repeating. A cannot be written as a fraction.
Answer B is not correct because the square root is not a whole number, or a perfect square. The square root has a non-terminating and non-repeating decimal, just like A. B cannot be written as a fraction.
Answer C is rational because it has a terminating decimal.
D and E are integers, which also can be written as fractions.
Out of the options given, C, D, and E have rational numbers, while all others do not.
The answers are C, D, and E.
