Doug earns $10.50 per hour working at a restaurant. He 1 3/4 hours cleaning 2 1/3 hours doing paperwork and 1 5/12 hours serving customers. what were his earnings?
(plz show the work)

$52.50

Step-by-step explanation:

take the hours and find the common denominator which is twelve. (1 9/12+2 4/12+1 5/12) Add them all up and simplify which would go from 4 18/12 to 5 6/12 to 5 1/12. Then multiply 10.50 by 5 because 1/2 isn't a full hour. That would get you 52.50

$57.75

Step-by-step explanation:

10 1/2*(1 3/4+2 1/3+1 5/12)=57 3/4

5/12=.42

1/3=.33

3/4=.75

10.50*(1.75+2.33+1.42)=57.75

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
