What does it mean to say that a number is a perfect square? Give one example of a number that is a perfect square and one that is not.
Can you plz help me?
I hate connectionas
Who else is in connexus and h8s it? The good thing for me is that its just for this year!!
A perfect square is the product of a rational number multiplied by itself.
4, 9, and 16 are perfect squares
1, 2, 3, 5, 6, etc. are not perfect squares
lolurmomUWU has a good point. I now do online school because I was bullied a lot and I could not function correctly in a regular classroom. I am very lucky to do school online because I don't want my depression and mental illnesses to get worse like it has in the past.
No I’m not thankful to be in an online school.
Especially with a family that beats me for no reason, makes me cry everyday. And drama on the internet. I’m not learning anything on online school.
This doesn't need to be responded to anymore, but I thought I might as well help.
1 (or 2 if you're writing it). Keep in mind, a perfect square is a number created by squaring a whole number. Squaring is known as "the result or product of multiplying a number by itself." Like Mrs. Sue said perfect squares are numbers like 4, 9, and 16. Why wouldn't a number be a perfect square? A number would not be a perfect square because "they cannot be expressed as the product of two equal integers."
3. irrational number
4. The Formula here would be 15^2+8^2=c squared
For anyone who doesn't understand the squaring process, it is simply (15 x 15)+(8x8)
Don't forget to square the answer!
5. So a perfect cube is basically a perfect square except you multiply by the third power.
Example: The square root of 216
6x6x6=216
6x6=36
36x6=216
Answer for the question: 125 because 5^3=125
6. 16 Squared+ (-8)= 4+(-8)= -4
-Integer: whole-valued negative or positive number (1, -2, 3)
-Irrational number: a number that cannot be expressed as a ratio (or a simple fraction)
-Radical: square root, cubed root, etc.
-Whole number: numbers that aren't decimals. (1, 2, 3, -4)
7. 25/64 squared
find the square root of 25 and then the square root of 64
5^2=25
8^2+64
5/8
8. This one is just estimating more so.
First, find the square root of 11 ( 3.31)
Now between the pieces of wood 3 ft, 4 ft, 5 ft, 6ft
Which could you use and cut off the least amount of wood?
3 ft is too small. 6 ft is too large.
9. This one is pythagoran theorum stuff. So instead of finding the hypotenuse or the diagonal, you are finding another side length.
6^2+h^2=8^2
36+h^2+64
64-36=28
Done? Not yet! You still have to square it.
28 squared is 5.29, so about 5.3
10. Chase. This is because you're estimating 54 squared. We know 7x7 (square root of 49) is 49 and 8x8=64. 9x9=81, that's too large. 6x6=36, that's too small. but the square root of 54 is just in between 49 and 64
11. 0.0202020 can be converted into a rational number because it is a repeating decimal.
12. It is a square wall, meaning the sides will all be the same length. 115 squared is 10.72. Thus, LxW
29x29 is wayy to large, as it equals 841. The closest would be 11x11
Thus, the answer is 11
13. Another square. 856 squared is 29.25. The approximate length is the number closest to 29.25 rounded
14. A rational number is a ratio, which can be written as a fraction. The answer would be: Every rational number can be written as a fraction.
15. I guess I sort of answered this with my example in #5. What to the third power is 216? so multiply by the same whole number three times. 6x6x6
ONLINE SCHOOL SUCKS BTW!!!!
BC YOU HAVE FAMILY MEMBERS ALWAYS CHECKING ON YOU AND IT GETS ANNOYING!!!! ALSO YOU DON'T GET TO SEE YOUR FRIENDS!!!!
AND YOU HAVE LIL BROTHERS ALWAYS MESSING UP STUFF AND BEING LOUD!!!! OH AND DRAMA MOST OF THE TIME!!!!
THINGS LIKE THAT ARE ANNOYING!!!!
okay jeez that was long, oops, didn't mean to make that long..
I hated public school. Im kind of an incell lol
What are all the answers?
I'm here hecause I got licked out of my old school lmao
...Honestly you guys should be grateful to be in an online school, yes I understand that it sucks to be in your house for most of the time, and not get hang out with your friends for most of day, but at least your not getting bullied, or having to deal with drama that YOU didn't need to get involved with or having anything to do with, or having sucky teachers that wont do jack crap because apparently they can't do anything about people calling you names, making fun of you, or threatening to beat you up EVERY SINGLE DAY! Now, I know not all schools are like that, and my old school was a crappy school, but STILL! Also, think of how much time you get to sleep in! (unlike me i have to still wake up like around 7 to help with my baby brother in the mornings, but that's not the point here), and you don't have to get out at a specific time, you can stop at any point in time without interrupting a class, and best of all...YOU DON'T HAVE TO GET DRESSED IN THE MORNING TO LOOK PRESENTABLE IN CLASS!
Ms. Sue why would those perfect and not perfect squares, be perfect or not?
Oh btw thanks ms.sue!! your the best!!
Thank you Ms. Sue
@Elly Same, I was bullied by students and teachers
You're welcome, Valerie,
Does anyone know all the answers I need them please help ASAP!
You can identify a perfect square because all of its sides will be rational. An example of a perfect square is the number 9. 9 is a rational number which means it can be expressed as a product of two equal integers. The equation would be 3*3=9. An example of a not perfect square is the number 5. It can not be equally expressed by two integers.
1.3
17
15
Integer
6\7
6 inches
10 inches
Chase
0.123...
13ft
12cm
Rational can be written as fraction
The square root of 2. 16 would be 6, therefore each side should be 6 inches.
The answer is irrational because the cube root of the number wasn’t a perfect cube
Figure B is the figure that proves the Pythagorean theorem. They are both perfect squares, so you have to add the length of the legs.
A: 9+36=46 (doesnt equal 64)
B: 25+144=169 (does equal 169)
I can see points from both sides, public school has has a higher bullying rate, but online school has down falls too. With online school you most likely have people around a lot. With public school you get to do more things like sports, band, ect, you also get to see people that is not your family. On the other hand online school you have more freedom over what you do in your day. Different things work for different people with different lives. I am not defending one side or the other, I am simply stating my opinion. I hope you have an amazhang day! :)
I'm stuck in connexus for idk how long so the bad thing is that idk when I can get the heck out
need help ......its a test
What's number 16
I need the answers for 16 and 17 because I will be kicked out of school if I don't get this test right
Keep the personal Life to yourself you IDIOTS
fizzoty is right i really don't like online schools you cant even talk to your friends, and everyone is always on your shoulder watching you and everyone is always messing with you 😡🤬that always how i fell and know one ever gets you because your different and then you fell horrible inside.
lolurmomUwU us online kids/people still get bullied we are just helping valerie
"I love getting bullied, yelled at, and waking up early!"
-said no one ever
@Fizzoty yeah but that’s assuming you have friends. i don’t have friends and let me tell you school without friends is horrible, especially when you have severe anxiety as well.
What about the short answers for 15, 16, 17?
Is ELLA's answer right??
Online school is fun for me cause, After im done with all my work I get to play games no my computer or watch youtube, and my friends live where I lvie so I see them everyday and I can leave class any time like say I finish my work at 12pm but we get out at 3pm I can leave at 12pm because I finished all my work also yall should be glad your working on online because when your struggling you can look up things to help you plus you dont really get in trouble in online school because they dont have you using zoom much and you can turn off your camera sometimes.
ELLA is right. Tysm. trust me
:))
wait 9 is wrong. 10 ELLA is wrong. it is 8 i think. ;-;
please answer the questions
now let me get back to what i was doin before detective dosh started talk dumb stuff
Same I just get lonely and because my parents are always busy. I am always alone. Plz stop making comments about how great your life might be ( I know that might not be in this chat), but it hurts because I don't have anyone.
A name you shouldn't know is kinda relatable, I like being able to get off as soon as I'm done not when the bell dismisses you. Like everyday I wake up at 9 ish and I finish all my connexus work at around 12am-1pm. And my dad's a math teacher so I can just go to him if I need help.
did someone really spell until as "entell"? also, where are the answers for Real Numbers and the Coordinate Plane Unit Test??? this test has the same first question as that one, but some of the questions are different. I can't seem to find answers for that test anywhere, and I don't want to get it wrong because it counts a lot toward my grade
so what are the answers?
also there are 17 questions
Wow that was a lot of reading.
hey valerie do you still exist
this test is really overdue and i can't find anything on this website for it. if anyone sees this, please help
Whenever I said c squared I met c^2 sorry
what are the answers???????? TWT
When a number is a perfect square, you find the sq. root of the number: the answer will be a whole number. For example, 4 is a perfect square because the sq. root is 2. When a number is not a perfect square, the sq. root will not be a whole number. For example, the sq. root of 6 is 2.449489743, which is a decimal.
Here is the answer make sure that you change the words a little. Make sure to read it all so you can still learn at least the concept.
same XD I got no one
To everyone saying they have no one to talk to, can relate. if you need someone to talk to though we can be friends :)
@UrmomlolUWU ok
@xiao same tho lmao!
yall dumb fr idc abt online i hate it yall be saying is better cuz u dont get bullied but matter fact that was never my case in school so online sucks
Hi, I can also see both points of sides, but you guys should not act that way because teachers put in there work for you. and maybe you guys should get friends then if you are alone. maybe get a fish or a rabbit then you have something to do. I do home school because I help my mom with my twin couisins we babysit three days a week. also i have two guinea pigs and they are great company.
