A square is a rectangle with equal sides.<br> True or False?
Digiron [165]
<h3>Answer:  True</h3>

Explanation:

A rectangle has all four angles that are 90 degrees. The side lengths may or may not all be the same length; however, we do know that the opposite sides are the same length.

A square is a special type of rectangle where all four sides are the same length and all angles are 90 degrees.

If a figure is a square, then it is automatically a rectangle, but not the other way around.

Simple....

you have: (3.2*103)+(5.78*105)

You want to simplify it..but first remember your order of operations...

1.) Remove the parentheses-->>

(3.2*103)=329.6

and

(5.78*105)=606.9

Which leaves you with...

329.6+606.9=

=936.5

Thus, your answer.

How do i turn 24% into a fraction
PolarNik [594]
You can remove the % sign if you divide the number by 100:

\frac{24}{100}


This is because % is defined as 1/100, and the name (per-cent) actually meant this originally!
we can also simplify it: let's divide it by 4:

\frac{6}{25}
