Answer:
x=36
Step-by-step explanation:
Question 1:
For this case we have that by definition, the GCF of two numbers is the largest number that is a factor of both numbers. For example, the number 10 is the biggest factor that 50 and 30 have in common.
We must find the GCF of the following expression:
We look for the prime factorization of each number:
The GCF of the three numbers is
So:
Answer:
Option C
Question 2:
For this case we have that by definition of power properties of the same base, that:
That is, for multiplication of powers of the same base, the same base is placed and the exponents are added.
So:
ANswer:
Option A
Answer:
Step-by-step explanation:
Answer:
Dorsey = 4.8 hours
Campbell = 24 hours
Step-by-step explanation:
It takes "x" hours for Dorsey
So, it will take 5 times more for Campbell, so
It takes "5x" hours for Campbell
Rate is inverse of time, so rates are:
Dorsey: 1/x
Campbell: 1/5x
We know Rate * Time = Work
When together, it takes 4 hours to finish a work, so we can write:
Solving for x, we get the time of Dorsey:
Dorsey takes 4.8 hours alone
Campbell takes 4.8 * 5 = 24 hours alone
There are 4 1/16 pieces
