A. a square is a parallelogram that has four congruent sides
It's 0.4 i'll show my work in a comment
Sod=1*1
to cover =30*14
to cover=420
to cover divided by one piece
=420/1
=420 pieces
Answer:
Step-by-step explanation:
90/100 * x = 15750
0.9 x = 15750
x = 15750/0.9
x = 17500
Now check this by taking 10% off. Do you get 15750?
Let's see
10/100 of 17500 = 1750
Subtract that from 17500
17500 - 1750 = 15750 which is exactly what you should get.
