There are total 30 students in the piano class.

<h3>What is Ratio and Proportion ?</h3>

When a number can be divided by another number then they can be written as p : q , when two ratios can be equated using an equal sign then they are said to be in proportion.

It is given that the total number of girls is 40% of the total students

The ratio of total students to girls is 100 :40

= 10 :4

= 5 : 2

It is also given that in the total number of students 12 were girls

Let total students be x

Then the ratio is x : 12

As both the ratio are same and so can be equated and the proportion will be

5 : 2 = x : 12

5/2 = x /12

x = 30

Therefore there are total 30 students in the piano class.

luda_lava [24]

The inequality that represents the possible length of the patio is √A < 625.

<h3 /><h3>How to represent an inequality?</h3>

Maddie's backyard is 25 meters by 25 meters.

Therefore,

area of the backyard = 25 × 25  = 625 m²

Hence,

She wants to put a square cement patio in her backyard.

A = area of the patio, in square meters.

Hence,

area of the backyard = 625 m²

Therefore, the inequality that represents the possible length of the patio is √A < 625.
