I am not sure but this is what I got-
217.39-14.95 to find the cost before the base fee. which is 202.44
then i did this= 202.44 / .84= 241
so the answer is 241 miles
Answer:
Step-by-step explanation:
P= {1,3,5,7,9,11,13,21}
R ={2,4,6,8,10,12}
O={3,6,9,12,15,18}
The union of two sets contain all the elements in either set.
R ∪ O = {2,4,6,8,10,12,3,9,15,18 } [6 & 12 are in both R and O. we have to write only one time]
P U (R ∪ O) = {1,3,5,7,9,11,13,21,2,4,6,8,10,12,15,18}
This is what I got putting this into to Desmos. Hope it helps :)
Answer:
The number is = 16
Step-by-step explanation:
Given:
Twice the sum of a number and 2 is equal to three times the difference of the number and 4.
To find the number.
Solution:
Let the number be =
The equation can be now written as:
Solving for
Using distribution:
Adding 12 both sides.
subtracting from both sides.
∴
Thus, the number is = 16
Complete Question
The model that describes the number of bacteria in a culture after t days has just been updated from to What implications can you draw from this information?
A The growth rate of the bacteria in the culture is 30% per day instead of
20% per day.
B The final number of bacteria is 3 times as much of the initial value instead
of 2 times as much.
C The initial number of bacteria is 3 instead of 2
D The number of bacteria triples every day instead of doubling every day
E None of the above.
Answer:
The correct option is D
Step-by-step explanation:
From the question we are told that
The first model is
The updated model is
Generally looking the two models that define the number of bacteria we see that at the for the first model that the number is being doubled everyday for example if the time is equal to 1 day we have that
Here we see that the constant 7 is being double but in the new model we can see that the number is being triple everyday , taking the same example with t = 1
=>
Here we see that the constant 7 is being triple for each day
Hence the implication of the model change is that the number of bacteria will be tripled everyday instead of being doubled everyday
