Sia ? 4 years, 6 months ago

In Triangle KMN, We have

PQ // MN

Therefore, KP/PM = KQ/QN

KP/PM = KQ/KN-KQ

4/13 = KQ / 20.4 - KQ

4(20.4 - KQ ) = 13 KQ

81.6 - 4KQ = 13 KQ

17 KQ = 81.6

KQ = 81.6/17

⇒ 4.8 cm.

Hence, the value of KQ = 4.8 cm.

Anmol Preet 4 years, 6 months ago

School uniforms should definitely be used in school system. Uniforms are both good for schools as well as students. Wearing uniform will help build a sense of unity within the school. Instead of everyone as a seperate team, everyone will be in the same team. Wearing uniform will help free students of the stress of what to wear in the morning. It will help to improve student individuality and improve their self-esteem. First, wearing matching uniforms can feel students feel equal. Poor students would no longer feel excluded because they are not wearing name brand clothes like the richer kids . Kids sometime tease each other because of the brand of clothes that they wear. Social status will also be less of an issue because everyone would be wearing the same clothing. Uniforms will improve student's individuality because they will have to express themselves through their personality and attitude, rather than through a brand name pair of jeans or an expensive pair od tennis shoes. Wearing uniforms will allow the teachers to form a precipitation of a student based on how they act not by how they dressed. Students social standing would be based more on individual character. Wearing uniform will help to impress student's self-esteem because they will not feel pressured to dress a certain way. Students feel pressured by other students when they can't dress like they dress. If all students are dressed the same, everyone will feel equal. Second, wearing uniforms will allow more time for studying. Students will be more focused on their school work or homework. Hence, uniform should be made compulsory.

The motherboard is the backbone that ties the computer's components together at one spot and allows them to talk to each other. Without it, none of the computer pieces, such as the CPU, GPU, or hard drive, could interact. Total motherboard functionality is necessary for a computer to work well.

Irrational

1Thank You

Sia ? 4 years, 6 months ago

Let us assume that 2/√7 is rational number.
2/√7= 2/√7 × (√7/√7)= 2√7/7. ( Rationalising)
Now, 2√7/7 = p/q ( as rational no. can be written in the form of p/q)
2√7= 7p/q
√7= 7p/2q
Here LHS is irrational but RHS is rational.
This contradicts the statement.
Our assumption is wrong.
2/ √7 is an irrational number.
