Mary put new tiles on her kitchen floor. The floor measures 6 feet long by 5 feet wide. she used 10 tiles to cover the entire fl
balu736 [363]

Answer:

30 square feet

Step-by-step explanation:

Number of tiles used for covering the kitchen floor = 10

Area covered by the floor = 6 * 5 feet^2                                                

                                        = 30 square feet

Length of each tiles = 3 feet

Width of each tiles = w feet

Area covered by each tiles = 3w square feet

Then the equation can be written as

3w * 10 = 30

30w = 30

w= 30/30      

   = 1 feet

10 *3w = 30

Please help me find the greatest common factor for these 2 problems..
Kisachek [45]

A greatest common factor is the largest number that goes into two or more numbers (in this case two). To find the GCF of two numbers, we have to find the prime factorization (how to express a number as a product of prime numbers) and then see which numbers are common in both of the prime factorizations.

11. The prime factorization of 12 is 3 * 2 * 2. The prime factorization of 18 is 3 * 3 * 2. Looking at the prime factorizations, we can see that both of them have 3 and 2. That means that the GCF is 3 * 2 which is 6.

12. The prime factorization of 48 is 2 * 2 * 2 * 2 * 3. The prime factorization of 80 is 2 * 2 * 2 * 2 * 5. We see that the numbers shared are 2, 2, 2, and 2. That means that the GCF is 2 * 2 * 2 * 2 or 16.
