Answer:

Volume of removed water = Length X width X decrease in water level

⇒ 18 = 20 X width X 0.15

∴ width = 6 metre

Step-by-step explanation:

Given:

A tank is in the form of a cuboid whose length is 20 metres. If 18 cubic metres of water is removed from it the water level goes down by 15 centimetres.

To find:

The width of the tank.

Solution:

The width of the tank is 6m.

To answer this question, we will follow the following steps:

As given, we have,

The length of a tank which is in the form of cuboid = 20m

Now,

When 18 cubic metres of water is removed, the water level goes down by = 15cm = 0.15m (as 1m = 100cm)

Now,

We know that the volume of a cuboid is equal to the product of length, breadth and height of that cuboid.

Here,

The volume of removed water

= length × width × decreased height of water

So,

[tex]20 \times width \times 0.15 = 18[/tex]

[tex]3 \times width = 18[/tex]

[tex]width = 6m[/tex]

Hence, the width of the tank is 6m.

There are 102 teachers in a school of 3300 students. Find the ratio of the number of teachers to the number of students

Solution:

Number of teachers in the school = 102

Number of students in the school = 3300

The ratio of the number of teachers to the number of students = Number of teachers in the school / Number of students in the school

= 102 / 3300

Here,

The factors of 102 are 2 × 3 × 17 and the factors of 3300 is 2 × 2 × 3 × 5 × 5 × 11

Now, the HCF of 102 and 3300 is 2 × 3 = 6.

= (6 × 17) / (6 × 550)

= 17 / 550
