The equation f=9/5c+32 relates temperature measured in degrees celsius, c, to degrees fahrenheit, f.

determine wether there is a proportional relationship between c and f.

This question is based on the ratio and proportion. Therefore, it is conclude that, yes,  there is a proportional relationship between C and F.

Given:

The equation F=9/5C+32 relates temperature measured in degrees Celsius, C, to degrees Fahrenheit, F.

We have to show that, there is a proportional relationship between C and F.

According to the question,

As we know that, ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, then ratios are proportional.

Let us take,  C=1. And, solve it further,

Now, taking C = 2 and solve it further.

It  is observe that, as we increases C then value of F decreases.

Therefore, it is conclude that, yes,  there is a proportional relationship between C and F.

yes they have a proportional relationship

Step-by-step explanation:

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

Step one : let us test say c=1

F=9/5*1+32

F=9/5+32

F=1.8+32

F=33.8

Say c=2

F=9/5*2+32

F=9/10+32

F=0.9+32

F=32.9

Observe that as c increases

F reduces Hence they have a proportional relationship

each side has a different length.  

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
