A group of hikers walked 2 1/4 km in 3/4 hour.The distance here varies directly with time. What is the constant of variation?
telo118 [61]

The distance depends on the time.

So now we need to find the constant of variation or the constant of proportionality.

To do so we must find y(the dependent variable) and x(the independent variable).

To find the constant(k) we must find y/x

Since y/x=k

Then 2.25/.75=k

k=3

Mai and Priya were on scooters. Mai traveled 15 meters in 6 seconds. Priya travels 22 meters in 10 seconds. Who was moving faste
nikklg [1K]

Answer:

Mai is moving faster than Priya.

Step-by-step explanation:

It is given that Mai traveled 15 meters in 6 seconds.

Speed=\frac{Distance}{Time}

The speed Mai is

\text{Speed of Mai}=\frac{15}{6}=2.5

Priya travels 22 meters in 10 seconds. Speed of Priya is

\text{Speed of Priya}=\frac{22}{10}=2.2

Since speed of Mai is more than the speed of Priya, therefore Mai is moving faster than Priya.

azamat
No, as if you reduce 4/16 it is 1/4, not 3/5, therefore they are not equivalent.

A rational number is defined as a number that can be written as a fraction and a number that terminates.

An irrational number is defined as a number that can't be written as a fraction and a number that has no end.

Step-by-step explanation:

4/7 is irrational because, in decimal form, it is 0.57142857...

Square root of 30 is also irrational because the square root is 5.47722557...

21 divided by square root of 4 is rational because square root of 4 is 2 and 21 divided 2 is 10.5.

pi is irrational because, in decimal form, it is 3.14159265....

-27 is also rational because it terminates
