Explain two different squares that can be made using the number 9

Answers

Answer: 1 and 81.

Step-by-step explanation:

Since, we have number 9 with help of  which we have to find a square.

If we divide 9 by 9 then we will obtain 1 which is itself a square.

That is,  (9)/(9) = 1

Now, If we multiply 9 by itself we obtain 81, which is the square of 9.

That is, 9* 9 = 81

Note: We can also make other squares by using number 9.




9/9=1
9x9=81.
 keep in mind that a square root is any number multiplied by itself to get another number

Which of the following options have the same value as 65%, percent of 20?

Answers

This question is incomplete. Hereis the complete question:

Which of the following options have the same value as 65% of 20?

(A) 0.65⋅20 (B) 65/100 divided by 20 (C) 65/20 * 100 (D) 65 * 20

Answer:

The correct answer is option (A) 0.65⋅20

Step-by-step explanation:

In this case they are asking us for an expression that is equivalent to 65% of 20. They are not asking us what is the value of that operation.

When we do a percentage calculation we can do it in two ways.

Let's see each one of them:

. (65 * 20): 100 =

  1300: 100 = 13

. 0.65. 20 = 13

As we can see both ways we get the same result.

Given this information we can say that the correct answer is option A.

Answer:

13

Step-by-step explanation:

You find out what is one percent then multiply from there

I really need help with these and my dad said the way i originally did it was wrong.

Answers

Excuse my saying this, but it's a little weird for your dad to tell you that
you're doing something wrong and then walk away and leave you hanging,
without helping you do it right.

And there's another weird thing here:  The equation you squeezed in there
in the blank line is EXACTLY CORRECT.  That's exactly the answer to the
next line, where it ways "Define a variable and then write ... an equation ...". 
You've already got that, and you're on your way.

In your equation, 'x' is the price of the second painting.  When you solve your
equation, you'll know that, and you'll be able to find the price of the first one. 
Then you'll immediately know which one was the most expensive.

The important thing is:  You've already finished the toughest part ! The rest
is just some arithmetic.  Great work !
