Answer:
Option C is the correct choice.
Step-by-step explanation:
We are given the coordinates of rectangle and we are asked to find the correct option that describes that diagonals JL and KM are congruent.
Since we that a rectangle have four right angles.
We will use Pythagorean theorem to prove that diagonals JL and KM are congruent.
In triangle KLM we can see that KL is b units long and LM is a units long. By Pythagorean theorem 
In triangle JML we can see that JM is b units long and LM is a units long. By Pythagorean theorem
Therefore, we can see that
and option C is the correct choice.
If Ian uses 1/20 of the ketchup 4 times, this is equal to 4/20, or

.

can be simplified to

, which means we need to work out

of 12.2

is equivalent to 20%, which as a decimal is 0.2
0.2 x 12.2 = 2.44 - however, this is how much he has
used, and we need to figure out how much is left.
12.2 - 2.44 = 9.76
So, Ian has 9.76 oz remaining :)
