Marcy started to draw a tree diagram to determine whether 2025 is q square number.
mady can use wha she has done far to determine that 2025 is a square number?
Guy says: my street adress is square number when you read the digits forward or backwards.
Is guy correct? Explain.
169
Try these yourself first please
for example you know sqrt 64 = 8 exactly
but sqrt 1000 = 31.622 etc
But I don't know how to do MY homework...I need some explanation...I live with my grand parents and I have no siblings!!!!
Determine wheather or not each number is a common factor of 144 amd 240 try to use diffrent methods and show your work
To determine which numbers are perfect squares, we need to find numbers whose square roots are whole numbers. Let's go through each option:
A) 64: The square root of 64 is 8, which is a whole number. Therefore, 64 is a perfect square.
B) 900: The square root of 900 is 30, which is a whole number. Therefore, 900 is a perfect square.
C) 120: The square root of 120 is approximately 10.95, which is not a whole number. Therefore, 120 is not a perfect square.
D) 1000: The square root of 1000 is approximately 31.62, which is not a whole number. Therefore, 1000 is not a perfect square.
E) 100: The square root of 100 is 10, which is a whole number. Therefore, 100 is a perfect square.
F) 10,000: The square root of 10,000 is 100, which is a whole number. Therefore, 10,000 is a perfect square.
Now let's look at the explanations given for each number:
A) 1225: The square root of 1225 is 35, which is a whole number. Therefore, 1225 is also a perfect square.
B) 484: The prime factorization of 484 is 2 x 2 x 11 x 11. Since each pair of factors is repeated, the number is a perfect square.
C) 2025: The square root of 2025 is 45, which is a whole number. Therefore, 2025 is a perfect square.
For the square with an area of 289 square units, we can find its side length by taking the square root of its area. The square root of 289 is 17, which is a whole number. Therefore, the square with an area of 289 square units is a perfect square.
Now let's determine if the following numbers are perfect squares:
(a) 16: The square root of 16 is 4, which is a whole number. Therefore, 16 is a perfect square.
(b) 144: The square root of 144 is 12, which is a whole number. Therefore, 144 is a perfect square.
(c) 1764: The square root of 1764 is 42, which is a whole number. Therefore, 1764 is a perfect square.
To check if Barrett can arrange the 225 square photos in a square, we need to find a whole number whose square is equal to or greater than 225. The square root of 225 is 15, which is a whole number. Therefore, Barrett can arrange the photos in a 15x15 square.
Now let's calculate the squares of the given numbers:
6 squared = 6 x 6 = 36
11 squared = 11 x 11 = 121
25 squared = 25 x 25 = 625
100 squared = 100 x 100 = 10,000
9 squared = 9 x 9 = 81
12 squared = 12 x 12 = 144
40 squared = 40 x 40 = 1,600
1000 squared = 1000 x 1000 = 1,000,000
To determine if 2025 is a perfect square, Marcy can continue drawing the tree diagram for the factors of 2025 until she finds a pair of factors that are the same. If she finds that 2025 has a pair of repeated factors, then it is a perfect square.
Now let's check if the street address "169" is a square number when read forward or backwards:
The square root of 169 is 13, which is a whole number. Since the same digits appear forward and backward, "169" is indeed a square number.
I hope this helps! Let me know if you have any other questions.
