How many palimdromic numbers is there between 300 and 400
blagie [28]

A palindrome is something that reads the same forwards and backwards.

If the number is a palindrome and it's between 300 and 400, then the
last digit must also be a ' 3 '. 

So all we have left to fill in is the digit in the middle.

There are 10 possibilities for that one ... the digits ' 0 ' through ' 9 '.

So there are <em>10</em> palindromic numbers between 300 and 400.

A shelf is designed so it will fit in a 90º corner between two walls. The shelf has dimensions, rounded to the nearest tenth, as
den301095 [7]

Answer:

Yes, it will fit snugly in a 90º corner

Step-by-step explanation:

To do this, we simply need to check if the given sides of the shelf is right-angled.

So, we have:

Hypotenuse = \sqrt{242

Side\ 1 = Side\ 2 = 11

To check for right-angle triangle, we make use of:

Side\ 1^2 + Side\ 2^2 = Hypotenuse^2

This gives:

11^2 + 11^2 = \sqrt{242}^2

121 + 121 = \sqrt{242}^2

242 = \sqrt{242}^2

242 = 242

This shows that the given sides of the shelf is a right-angled triangle.

Hence, it will fit the wall

Anna007 [38]
When you subtract and add what is in the parentheses you would get -15 so I’m guessing he didn’t go from left to right when working inside the parentheses but when you solve the whole problem out you would get the answer: -41.25 If I missed something or you need me to show the work just let me know but I hope this helps !

Marcus made a mistake in Step 2. 5/2.5 is 2 not 3.
