360/18=20
So, your answer is 20 unit rate.
Hope this will help you!
Assuming the missing parenthesis is at the end the simplified answer should be k-8
Answer:
There are a total of
functions.
Step-by-step explanation:
In order to define an injective monotone function from [3] to [6] we need to select 3 different values fromm {1,2,3,4,5,6} and assign the smallest one of them to 1, asign the intermediate value to 2 and the largest value to 3. That way the function is monotone and it satisfies what the problem asks.
The total way of selecting injective monotone functions is, therefore, the total amount of ways to pick 3 elements from a set of 6. That number is the combinatorial number of 6 with 3, in other words
Answer: $16.60
Step-by-step explanation:
5.80+ 3.60= 9.40+ 3.60= 13.00+ 3.60= 16.60
So after 4 weeks he earned $16.60
For this case, the first thing we must do is define variables.
We have then:
x: amount of time the assistant works
Y: amount of time the experienced person works
We then have the following system of equations:
x + y = 4
y = (1/2) x
Solving the system we have:
x = 8/3
y = 4/3
Answer:
It would take the roofer, working alone, to complete the same job about:
y = 4/3 hours
