Answer:
5cm
Step-by-step explanation:
Given data
Length= 3cm
Width= 4cm
Applying Pythagoras theorem
z^2= x^2+y^2
z^2= 3^2+ 4^2
z^2= 9+16
z^2= 25
square root both sides
z= √25
z= 5cm
Hence the diagonal is 5cm
Answer:
Step-by-step explanation:
21/3 = 16/6
126 ≠ 48
does not form a proportion
Answer: 3 x 5
Step-by-step explanation: To find the prime factorization of 15, first create a factor tree with two branches. Since 15 ÷ 3 = 5, we know that 3 and 5 are factors of 15. So we write 3 and 5 at the bottom of the branches.
While 1 and 15 are also factors, we don't use them in out factor tree. That's because when finding the prime factorization, we always use numbers other than 1 and the number itself.
Next, we circle any prime factors in the factor tree. Since both 3 and 5 are prime, we circle both 3 and 5. Since we have circles at the bottom of all of our branches, we are finished.
So the prime factorization of 15 is 3 x 5.
Notice that we write our prime factorization as a multiplication problem. Think of the prime factorization of a number as the prime factors of the number that you multiply together to get the original number.
Answer:
6 and 18 are common because 6x3=18. Remember the rule to multiply all numbers by 3. So multiply 10 by 3 and you will get 30. The total number of square tiles needed is 30 tiles. If you are putting it into a ratio it would be 18:30.
The fourth option would be the answer.
