Answer:
9
Step-by-step explanation:
Side EF is 12 units, so you have to multiply 12 by 3/4, and you get 9.
61.296% and if u have to round 61.3% hope this helped
In its decimal form, it says ' 64 / 100 '.
In order to change it to its lowest terms, we look to see whether the
numerator and denominator have a common factor greater than ' 1 '.
If they do, then we can divide numerator and denominator by their
common factor, and have the same fraction in lower terms.
The common factors of 64 and 100 are 1, 2, and 4 .
We could divide top and bottom by 2, but that wouldn't finish the job.
It's always best to divide them by their <u>greatest</u> common factor, and
once you do that, you're done.
Dividing the numerator and denominator both by 4,
we get the fraction in its lowest terms:
0.64 = 64/100 = <em>16/25</em>
Here is the first sign that should tell you this isn't a rectangle.
d=_/w^2+l^2 is the equation to solve the diagonal of a rectangle
if you plug in 21 and 20, d would equal 29 not 28 so for that reason alone it is not a rectangle.
I am about 90% sure the correct answer is B. I hope this helps let me know if I was right.
Option B!
