Answer:
$0.84 I think is the answer
The smallest county is 129 square miles large.
Step-by-step explanation:
Let,
Smallest county = x
Largest county = y
According to given statement;
The largest county in the state of Texas is 6064 square miles larger than the smallest county in the same state.
y = x+6064 Eqn 1
The size of the largest county is 48 times the size of the smallest county plus one square mile.
y = 48x+1 Eqn 2
As Eqn 1 and Eqn 2 are both equal to y, therefore,
Eqn 1 = Eqn 2
Dividing both sides by 47
The smallest county is 129 square miles large.

Answer:
D
Step-by-step explanation:
When something depreciates completely, it will have a total value of 0 dollars. Therefore, set the equation to zero and solve for <em>t</em> to find the years.
Therefore, the table saw will completely depreciate after 9 years.
0.25x + 37.68 = C
[The company charges $0.25 per mile (x) plus $37.68, and C is the total amount of money/cost]
Vanessa has $120 [total amount of money she is given per day],
Since this is the total amount of money she has/can pay with, you can plug in 120 for C
0.25x + 37.68 = 120 Subtract 37.68 on both sides
0.25x = 82.32 Divide 0.25 on both sides
x = 329.28
Vanessa can travel 329.28 miles on the $120
where
- P is the population
- P₀ is the initial population
- r is the rate
- t is the time
In the given problem, r = 2 (because the amoeba double every hour). So,
