Your answers are:
Step-by-step explanation:
A) 0.5
B) 1/2
How do we get from a decimal to a percent? We multiply by 100. So 0.5 * 100 = 50%. A) is correct.
How do we go from a fraction to a percent? Percent means "out of 100" so a fraction out of 100 is how you can tell if the percent matches the fraction.
1/2 = ?/100
1/2 = 50/100
Half of 100 is 50, so B) is correct.
To save the explanation, C) and D) are incorrect because C) ends up being 5% while D) ends up being 2%.
Your answer is A) and B).
I hope this helps!
Area is maximized and perimeter is minimized by using a figure that is as close to equilateral as possible. Using the barn as one side of the pen, that means the farmer has 3 sides to fence. 300/3 = 100 feet for each side (this will make the figure equilateral). This makes a square pen with dimensions 100 x 100. This makes the area 10000 ft².
Answer:
Grouping.
Example: x² + 2x + 3x + 6 = (x + 2)(x + 3)
