From the question, we know that
a ballroom features a square dance floor, which has an area of 400 square feet.
The formula for the area of a square is the side squared. Hence, we can determine the side length. Taking the square root of both sides, upon increasing the side length by one foot, we arrive at a side length of 21 feet, which is not a perfect square. The area of 441 is indeed a perfect square and a rational number. Consequently, the true statements are A and E.
Answer:
The expression representing the sum of three times a number and six, over the difference of seven times that number and nine
Step-by-step explanation:
we have

Let
p -----> the variable
we understand that
In the numerator we have (3p+6)
The statement that corresponds to this algebraic representation is "The sum of three times a number plus six"
The denominator is (7p-9)
The statement that corresponds to this algebraic representation is "The difference of seven times the number and nine"
therefore
The statement that represents this problem is "The sum of three times a number and six, divided by the difference of seven times the number and nine"
Answer:
and these represent genuine solutions.
Step-by-step explanation:
We have

Factor both sides' denominators.

Simplify.

Hi! I arrived at the answer of 15%. Step-by-step explanation: 1. A useful formula for calculating percentage increase is: ((New Number - Old Number) / Old Number )*100 = Percentage Increase. 2. Thus, (3.68 - 3.20) / 3.20 = 0.15. 3. Then, multiplying 0.15 by 100 yields 15%. I hope this is helpful!
When faced with a pile of pennies, if I need to determine whether the count is even or odd without actual counting, I understand that even numbers are divisible by 2, while odd numbers are not. I would arrange the pennies into two rows and form pairs of 2. If there's an additional penny left after pairing, this signifies an odd total; conversely, if all can be paired off, then the number is even.
