Answer:
Step-by-step explanation:
Given information: |a| = 80, |b| = 50, the angle between a and b is 3π/4.
We need to find the dot product a · b.
The formula of dot product is
where, θ is the angle between a and b.
Substitute the given values in the above formula.
Rationalize the above equation.
Therefore, the value of a · b is .
You have to make a proportion:

Answer:
Step-by-step explanation:
Please consider the complete question.
Wyatt is working two summer jobs, washing cars and tutoring. He must work no less than 12 hours altogether between both jobs in a given week. Write an inequality that would represent the possible values for the number of hours washing cars, w, and the number of hours tutoring, t, that Wyatt can work in a given week.
The number of hours altogether between both jobs would be .
Since Wyatt must work no less than 12 hours altogether between both jobs in a given week, so hours in both jobs should be greater than or equal to 12. We can represent this information in an inequality as:
Therefore, our required inequality would be .
