To solve, you need to find the least common multiple of the denominator.
In this case, its 30.
3*9= 27/30
1*10 = 10/30
She walked 37/30 miles or 1 mile and 7/30th of a mile
This is a very good question to know about. People who make tests really like it.
The way to solve it is to make the slower car stop and use the difference in speed = to the rate. then do it as an ordinary d = r*t problem.
The difference in speeds is 44 - 36 = 8 miles/ hour.
d = 260 miles
r = 8 mph
t = ???
t = d/r
t = 260/8
t = 32.5 hours.
Thats 32 1/2 hours.
Answer:
39 degrees
Step-by-step explanation:
It is shown that there is a 90 degree angle one part is given so 90-51=39 degrees.

Answer:
Step-by-step explanation:
Since we want to know the actual number of feet, we can write the proportion with that in the numerator.
The real caboose is 42 1/4 feet long.
First we observe pattern here. The pattern is one number "1" and one number "2" than two numbers "1" and two numbers "2" and so on. Every next array of numbers 1 and 2 will have one extra member.
Because of this, 0.121122111222... isn't repeating decimal. Repeating decimal has some number of decimals that keep repeating. For example if we had:
0.121122 121122 121122 ... this would be repeating decimal because 121122 segment keeps repeating.
In your task you can't find a segment that keeps repeating.
