Composition about myself in 150 words​
tigry1 [53]

Answer:

I am a student who’s studying in a prestigious college in Bangalore city. It’s a city where I grew up. I live in a town with my family. The school I studied till 12th is also in the town.

Things I am good at

Almost everyone is kind at least one sport. The one competition that I am good at is basketball. In my school, almost everyone had an obsession with the sport, and so did I. Every game period, my teacher would make us play basketball, along with other games. Over the years, the way I played basketball improved, and while learning the game, I discovered other lessons as well. One of the lessons I’ve learned is how to play in a team. When you play in a group, you depend on each other for winning.

I have always been energetic and lively. While many people feel awkward and weird, making me friends, I have no problems with making new friends. I can talk to everyone quickly and know them.

This is not about me took it from the web!!

Hope it helps!!!

Dang it these are tricky for me can somebody help?
erica [24]

Answer:

It has no perfect square factors, unless you count 1 = 1^2. That's sort of a degenerate case we don't usually count, since every integer has that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!

A college student completed some courses worth 3 credits and some courses worth 4 credits. The studentearned a total of 59 credi
Korolek [52]

Answer:

<em>The student completed 13 courses worth 3 credits</em>

Step-by-step explanation:

<u>System of Equations</u>

Let's assign the following variables:

x = number of courses worth 3 credits

y = number of courses worth 4 credits

Some student completed 18 courses thus:

x + y = 18      [1]

The student earned a total of 59 credits:

3x + 4y = 59       [2]

From [1]:

y = 18 - x

Substituting in [2]:

3x + 4(18 - x) = 59

Operating:

3x + 72 - 4x = 59

Simplifying:

-x = 59 - 72 = -13

x = 13

The student completed 13 courses worth 3 credits
