The answer is b ...........................................................b............b..............
So first you would have to add 10 and 1/8 and 3 and 5/8 which is 4 and 3/4 then add 2 and 7/8 to 4 and 3/4 which is 7 and 5/8 so 7 5/8 is the answer.
Answer:
8 minutes
Step-by-step explanation:
120÷ 15= 8
yup thats pretty much it
Answer:
h = 9 cm.
Step-by-step explanation:
V = kBh where k is the constant of variation.
From the given info:
32 = k*16*6 = 96k
So k = 32/96 = 1/3.
So we have the equation of variation:
V = 1/3Bh
When V = 60 B = 20, so:
60 = 1/3 20h
20h = 60 * 3 = 180
h = 180 /20 = 9.
By setting up a system of equations we can easily solve this problem. Let's denote Jane's working hours with x and Jack's working hours with y. Since they don't want to work more than 65 hours, the first equation is x+y=65. The second equation is 14x+7y=770. By solving this system of equation

, we find that y=20 hours, which is Jack's maximum working hours.
