Answer:
First question the answer is the third one, 4*4*4*4*4
Second: Part A
I think one side is 25 yards, so answer is 25². that makes the area of the chicken pen to be 625 sqaure yards.
Part B a yard is exactly three feet, so the power becomes 75², and the area is 5625 square feet.
third question: not sure what the only use once is, but 2^4 and 4² could be the first one, they both equal 16. The second could be 3^4 and 9^2, which are both 81.
6.43125...
To the nearest cent, I'm assuming they mean, 6.43, since there is no 5 or higher number in the thousandths place...
Answer:
Step-by-step explanation:
12.
(A). AB = √34 units
(B). Area of triangle is 7.5 units²
Perimeter of triangle is (√34 + 8) units
(C). ΔA'BC is reflection of ΔABC over y = 2
(D). ΔA'BC is right angled. ΔABA' is isosceles.
First multiply the original price by the discount. (250.99 x .78 = 195.7722)
Then subtract that number from the original. (259.99 - 195.7722 = 55.2178)
Then round to 2 decimals because dealing with money.
