Answer:
percent means <u>per hundred </u>
Between the 100 squares, 60 of them are shaded
so you do 60/100
it's kind of like correcting tests, you have 100 questions, you got 80 of them right so its going to be 80/100
when you calculate percentage, you do the fraction x 100
so it's 60/100 = 0.6 x100 = 60%

Answer: A, 102
Step-by-step explanation:
Okay so just find the big square and subtract the holes
big square is 30x20 which is 600
hole #1 is 20x5 = 100
hole #2 is a triangle so you first find the base and height which are 10 and 5 respectively. Then use the triangle area formula a = 1/2bh to find that the triangle's area is 25.
Subtract the holes now
600-100-25 = 475
1 Gallon = 200 square feet covered so divide 475 by 200 to find how many gallons should be used. It's 3 gallons since you can't just buy a fraction of a gallon (Unless your being weird).
One gallon is 34, so 3 gallons is 3*34 = 102
Or in other words... A
hope you learned and can incorporate these methods for future problems :D!
