Gary makes $7.48 an hour . he made $310.42 last week. how many hours did he work?
To find the number of hours Gary worked, we can divide his total earnings by his hourly wage.
number of hours = total earnings / hourly wage
number of hours = $310.42 / $7.48
Calculating the result:
number of hours ≈ 41.5
So, Gary worked approximately 41.5 hours last week.
is the number 14 prime or composite?
The number 14 is composite because it has factors other than 1 and itself. Specifically, 14 can be divided evenly by 1, 2, 7, and 14.
use the ladder method to find the gcf of 12 and 28
To find the greatest common factor (GCF) of 12 and 28 using the ladder method, we write the prime factorization of each number and look for the common factors.
Prime factorization of 12: 2 * 2 * 3
Prime factorization of 28: 2 * 2 * 7
Now, we write the prime factors in a ladder diagram, aligning them vertically:
12 = 2 * 2 * 3
28 = 2 * 2 * 7
Next, we look for common factors and write them on the right side of the ladder:
12 = 2 * 2 * 3 2
28 = 2 * 2 * 7 2
We multiply the numbers on the right side to find the GCF:
GCF = 2 * 2 = 4
Therefore, the GCF of 12 and 28 is 4.
Its wrong
My apologies for the mistake. Let's correct the ladder method.
We start by finding the prime factorization of each number:
12 = 2 * 2 * 3
28 = 2 * 2 * 7
Then, we create a ladder diagram:
12 = 2 * 2 * 3
28 = 2 * 2 * 7
Now, we look for the largest common factor in the ladder. In this case, both numbers have 2 and 2 as common factors, so we write it on the right side of the ladder:
12 = 2 * 2 * 3 2
28 = 2 * 2 * 7 2
To find the GCF, we multiply the common factors on the right side:
GCF = 2 * 2 = 4
Therefore, the GCF of 12 and 28 is 4.
