Question

neena is listening to a song. It has a consistent beat. She counts 11 beats in 5 sec. what is the C.O.P for the realtionships of beats to minute.

Answer 1

2.2

Explanation:

1. COP= constant of proportionality

What does that mean? This is how much of something you need for the variables to be proportional no matter their value. For example, if you pay 1.99 for 1 gallon of gas but then 30 dollars for 2 gallons at the same gas station, it doesn't make sense. You need to pay $3 for 2 gallons, and so on.

2. How do we find COP?

K is going to represent the constant of proportionality (COP), what we are solving for. Your equation should be k=b/a.

3. B is what comes first in the ratio, and is second. They said "beats to minutes" so beats= b and minutes= a

3. Solve: 11/5= 2.2

Answer 2

Explanation:

The proportional relation is y= 2.2x

What is proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

Neena counts 11 beats in 5 seconds

So, x=11 and y=5

Using the proportionality

y = k x

k= y/x

k= 11/5

k= 2.2

Hence, the proportional relation is y= 2.2x
