I dont understand this question, what does it mean by "perfect square' square root maybe ??
Sam purchased 625 square feet of carpet for his bedroom, which is shaped as a square. What are the dimensions of his bedroom?
Each side of the bedroom has a length of 25 feet.
Each side of the bedroom has a length of 156.25 feet.
Each side of the bedroom has a length of 390,625 feet.
Each side of the bedroom has a length of 312.5 feet
I think it is either 25 feet or 156.25 feet.
Estimate the value of square root of 50
between 5 and 6
between 6 and 7
between 7 and 8****
between 8 and 9
Thank you for taking the time to go through my answers , if you could help i would be grateful
Could i get some help please ?
1. A = 100Ft^2.
L = sqrt(100)= 10Ft. = Length of each side.
10Ft/side * 4sides = 40 Ft.
3. A perfect square is a number whose square root is a whole number:
9, 25, 144 and 36 are perfect squares, because their square root is a whole number.
4. sqrt(625) = 25 Ft./side.
5. Correct.
Thank you henry for the first questioned you answered helped me understand more, and it is correct the #1 answer that henry did.
Im pretty sure all his answered are correct but don't count on me, count on your knowledge.
Sure, I'm happy to help explain the answers to your questions!
1. Suzanne wants to put a fence around her square garden. The area of the garden is given as 100 square feet. To find the length of one side of the square, we need to find the square root of the area. The square root of 100 is 10, so each side of the square garden is 10 feet. Since a fence goes around all four sides, Suzanne would need 10 feet x 4 sides = 40 feet of fencing. Therefore, the correct answer is 40 ft.
2. An irrational number is a number that cannot be expressed as a simple fraction or a terminating or repeating decimal. Out of the options given, 0.1212121212... is a repeating decimal. The other options are terminating decimals or can be expressed as fractions. Therefore, the correct answer is 0.1212121212...
3. A perfect square is a number that can be obtained by squaring an integer. In this case, we need to find the number that, when squared, gives us the options given. The only number that is a perfect square is 32, which is 4^2. Therefore, the correct answer is 32.
4. Sam purchased 625 square feet of carpet for his square-shaped bedroom. To find the dimensions of the square, we need to find the square root of the area. The square root of 625 is 25. Therefore, each side of the bedroom has a length of 25 feet. The correct answer is 25 feet.
5. To estimate the value of the square root of 50, we need to find the two whole numbers between which the square root of 50 lies. The square root of 49 is 7, and the square root of 64 is 8. Since 50 is between 49 and 64, the square root of 50 is between 7 and 8. The correct answer is between 7 and 8.
I hope this helps! Let me know if you have any other questions.
