The first one is 75% i think I dont know if thats the answer though hold on and I'll get you the others
In mathematics there is a rule of exponents where we can "distribute" the powers/exponents in the numerator and denominator of any expression. Therefore, given an expression as 
, the exponent n can be "distributed" as: 
.
In our case, the power, n=11; a=7 and b=4. Thus, the expression 
, can be written as 
.
Thus, out of the given options, option A is the correct option.
I don't know exactly i think its either 3 grams or 7 grams or 2 1/2 grams
sorry if its wrong
Answer:
f(x) = -2*sqrt(x - 7 + 1)
Step-by-step explanation:
If by "statement" you mean equation, then it's pretty self-explanatory. Sorry if I'm confused though, you probably didn't list the proper choices.
The problem does not clearly give us the distance from Buffalo to Chicago, so let this be x (in mile) just so I can show you how the total cost is solved.
The total cost is equal to the sum of the rental fee plus the cost of the additional fee per mile which is equal to 1.50x, and also of the cost of the gasoline which is equal to (x/16)(2.15). Thus, the final answer should be expressed as,
total cost = 29.95 + 1.5x + 2.15x/16
When the distance is available, this should be easily substituted in the equation above.
