Answer:
1.5lb/ounces
Step-by-step explanation:
Given:
Mass of dry ice Carmen uses = 12lb
Mass of root beet = 8ounces
Unknown:
Ratio/Proportional constant for number of pounds to number of ounces of root beer extract = ?
Solution:
To solve this problem,
Ratio = 
Ratio = 
= 1.5lb/ounces
Present value, PV = $500
Future value, FV = 2*PV = 2*500 = $1,000
Rate, r = 4% = 0.04
Compounding times in a year, n = 4 (compounded quarterly)
Time, t = ??
The future value expression is stated as:
FV = PV (1+r/n)^nt
Substituting;
1000 = 500 (1+0.04/4)^4t
2 = (1.01)^4t
ln 2 = 4t ln 1.01
0.6931 = 4t* 0.00995
0.6931 = 0.0398t
t = 17.414 years
Time required for the amount to double is 17.41 years.
In standard form it would be 8,000,309
Answer:
35
Step-by-step explanation:
PEMDAS
(18-7) = 11
3(11) = 33
33 + 2 = 35
