Divide by 6 and divide the caw of squaw squaw
Answer:
5000J
Explanation:
Given in the question that
Heat added to the coffee cup is, ΔS = 20 J/K
The temperature of the coffee, T = 250 K
Now, using the formula for the entropy change
...........(1)
Where,
ΔS is the entropy change
ΔH is the enthalpy change
T is the temperature of the system
substituting the values in the equation (1)
we get

ΔH=250×20
ΔH=5000 J
Answer:
a. $79,122.50
b. 314. 84 miles.
c. 700 ways.
Explanation:
a. Compound interest = A = P (1 + r/n)nt ;
where P = 7500 (principal amount)
r = 15% (interest rate)
t = 16 (no of years)
n = 4 (no of times compounded annually.)
and finally A is the Amount (present value after 16 years)
Upon calculation A = $79,122.50.
b. Answer: 314. 84 miles.
Explanation:
Given data. 160 miles / 7.75 liters of gasoline
Therefore 1 liter of gasoline = 160/7.75 = 20.645 miles/ liter.
15.25 liters of gasoline = 20.645 * 15.25 = 314.84 miles.
c. Answer: 700 ways.
Explanation:
This is an application of generalized principle of counting.
4 Americans can be choosen from 7 Americans = 7C4 = 35
3 Russians can be choosen from 6 Russians = 6C3 = 20.
Total number of ways = (7C4)* (6C3) = 35 * 20 = 700 ways.
