Answer:
Vel. of the car = 3.33 meter per second.
Explanation:
In given graph, y axis represent the distance traveled by the car and x axis represent the time taken by car.
At time t = 30 seconds , distance traveled by the car is 100 meter
We know that,
Speed = 
speed = 
speed = 3.33 meter per second
That's the final answer.
I hope it wil help you.
The change of base formula looks like this:
log x
(log to the base b of ) x = ----------- (you could also use ln instead of log)
log b
log 40 1.602
Then (log to the base 7 of) 40 = ------------ = ------------- = 1.896 (answer)
log 7 0.8451
check (on calculator): 7^1.896 = 40.023 (close enough to 40 to verify
that this method "worked")
7y - 23 + 23x -16 + 8x - 21
31x + 7y - 60
What is the original problem equal to? You can't go any further unless you know.
Answer: C. 625 and 81
Step-by-step explanation: A relatively prime pair is a pair in which in both numbers given, the only number that can go into each number is one. In 112 and 36, we know 2 can evenly go into each number because they both end in a positive number (112/2 is 56 and 36/2 is 18.) This means A is incorrect. As for B, 11 can evenly go into each number, leaving you with 25 and 7. B is incorrect. And then there's D. 5 can go into each number giving you 160 and 19. D is incorrect.
C is correct because the only numbers that can go evenly into 81 is 1, 3, 9, 27, and 81. None of these numbers, except one can go into 625 also.
