Answer:
(c) 5/2
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
a^-b = 1/a^b
__
Using these rules, we can simplify the expression as follows:
(5^-3)(2^2)(5^6)/((2^3)(5^2)) = (5^(-3+6-2))(2^(2-3)) = (5^1)(2^-1)
= 5/2
Answer:
x = 
Step-by-step explanation:
3x+6 = 4x^2
4x^2 -3x -6 = 0
x = 
Answer:
(1/4) hr/mile
Step-by-step explanation:
4 mph can be rewritten using other units of measurement:
Suppose we convert 'miles' to 'feet:'
Then:
4 miles 5280 ft
---------- * ------------- = 21120 ft/hr
1 hr 1 mile
Note that we could invert 4 mph and obtain
1 hr
-------- or (1/4) hr/mile
4 mi
Graph D is the answer to this question
Answer:
p = 55 + 35h
Step-by-step explanation:
Let p and h represent the price of the service call and the hours worked, respectively. The price charged is 35 dollars for each hour, so the time-based part of the price is 35h. The base fee of 55 dollars is added to that for a total price of ...
p = 55 + 35h
