Answer: A, D
Step-by-step explanation:
68 is the initial amount.
A is correct because 0.2(68) represents 20% of 68. Since you're looking for 80% of 68, you subtract 0.2(68) from 68.
D is correct because it directly takes 80% of 68, which is what the question is asking for.
Answer:
Perimeter = 16x + 16
Area = 40x + 15
Step-by-step explanation:
Perimeter = the sum of all the side lengths
Perimeter = 2(8x+3) + 2(5) = 16x + 6 + 10 = 16x + 16
Area = product of base times height
Area = (8x+3)*5 = 40x + 15
Answer:
1/2 yard
Step-by-step explanation:
1/3 yard x 6/6 = 6/18 yard
1/6 yard x 3/3 = 3/18 yard
6/18 + 3/18 = 9/18 = 1/2 yard
Formula for finding the area of a triangle:

Where b is the base and h is the height.
Substitute the variables for the values.


A = 270
So, the area is 270 square centimeters.
