33.33? im not sure, but you do a/b=p/100. p is the percent, a is the part of the whole number, b. so the equation would be 20/b=60/100. then you do cross multiplication (60b=2000) then you divide.
Hello!
Advantages of a capitalist economic system:
• Economic growing and expansion.
• Consumer choice (The consumers get to choose what to consume, which leads to better products and services).
• Efficiency of economics (Goods and services based on demand)
Disadvantages of a capitalist economic system:
• Inequality (A small group of people hold most of the wealth)
• There can be a monopoly of power (a specific enterprise is the only supplier of particular commodity)
• Unemployment
• Social benefit ignored. A free market will ignore externalities.
No, I feel the disadvantages outweigh the advantages, because there are more of them.
Answer:
The answer is D
Step-by-step explanation:
Answer:
The constant in the expression is 12
Step-by-step explanation:
The constant of the expression is the value that is independent of the number of minutes Janelle uses. The expression can be written as :
f(m)=0.05m +12
Example if m is 1 or 2
f(1) = 0.05(1) +12 = 12.05
f(2= = 0.05*2 +12 =0.1 +12 = 12.1
The value 12 is the minimum price of the bill indepent of the consumption of minutes of Janelle. She will always be charged this value.

Answer:
(a) x = (3 -ln(3))/5 ≈ 0.819722457734
(b) y = 10
Step-by-step explanation:
(a) Taking the natural log of both sides, we have ...
2x +1 = ln(3) +4 -3x
5x = ln(3) +3 . . . . . . . . add 3x-1
x = (ln(3) +3)/5 ≈ 0.820

(b) Assuming "lg" means "log", the logarithm to base 10, we have ...
log(y -6) +log(y +15) = 2
(y -6)(y +15) = 100 . . . . . . . taking antilogs
y^2 -9x -190 = 0 . . . . . . . . eliminate parentheses, subtract 100
(y -19)(y +10) = 0 . . . . . . . . factor
The values of y that make these factors zero are -19 and 10. We know from the first term that (y-6) > 0, so y > 6. That means y = -19 is an extraneous solution.
The solution is ...
y = 10

When solving equations using a graphing calculator, it often works well to define a function f(x) such that the solution is f(x) = 0, the x-intercept(s). That form is easily obtained by subtracting the right side of the equation from both sides of the equation. In part (a) here, that is ...
f(x) = e^(2x+1) -3e^(4-3x)
