Lana71 [14]

Answer:

$127.50

Step-by-step explanation:

To answer this you will need to figure out how many days each person is working each week based on their number of hours and how many hours they work. Use this to determine the number of dogs groomed and then multiply by the hourly rate.

Dana works 4 days (40/10) and Monique works 5 days (40/8).

Dana: 15 dogs per day x 4 days a week x $12.75 per dog = $765 a week.

Monique: 10 dogs per day x 5 days a week x $12.75 per dog = $637.50 a week.

765 - 637.50 = $127.50.

The difference is $127.50.

a quantity of ethanol is cooled from 47.9° C to 12.3°C and releases 3.12 KJ of heat. what is the mass of the ethanol sample?

victus00 [196]

Answer:

35.9 grams

Step-by-step explanation:

We use the formula:

$q=m*C_p*\Delta T$

Where

q is heat released

m is mass

C_p is the constant 2.44

ΔT is change in temperature

We put the info in the formula and solve for m (mass):

$q=m*C_p*\Delta T\\-3.12 = m*2.44(12.3-47.9)\\-3.12*10^3=m*(-86.864)\\m=35.9$

The mass of ethanol is 35.9 grams
