The value of y for proportional relationship when x = 30 is y = 135.

<h3>What is proportional relationship?</h3>

Relationships among two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relation, one variable is consistently equal to the other's constant value.

A "constant of proportionality" is the name of this constant.

the importance of proportional relationship are-

  • Students' grasp of numerous areas in science and maths depends on their ability to use ratios and proportions.
  • They play a crucial role in the development of slopes, uniform rate of change and other concepts and abilities that are essential to understanding and mastering algebra.

Calculation the for the value of y.

According to the question,

The variables y and x have a proportional relationship.

Where, y=9 when x=2

Thus,

y/x = 9/2

Cross multiplying the above result;

2y = 9x

The value of y when x = 30.

2y = 9×30

2y = 270

 y = 135

Therefore, the value of y when x=30 is 135.

3. Galshore of Maloat is making a journey from the island of Gont to Oranea. The distance from the two lands is 965 miles. Galsh
USPshnik [31]

Answer:

  3.  about 7.48 hours

  4.  about 1.8892 hours

Step-by-step explanation:

Both of these questions make use of the relation ...

  time = distance / speed

3. time = (965 mi)/(129 mi/h) ≈ 7.48062 h ≈ 7.48 h

__

4. time = (612.1 mi)/(324 mi/h) ≈ 1.889198 h ≈ 1.8892 h

(We have rounded the time to sufficient precision so that the distance at the given speed rounds to the number given.)
