A taxi service charges an inital fee of $3 plus $1.80 per mile.how far can you travel on $12
Answers
isolate the x
1.80x + 3 (-3) = 12 (-3)
1.80x = 9
1.80x/1.80 = 9/1.80
x = 9/1.80
x = 5
you can travel up to 5 miles
hope this helps
$12 < $3 + $1.80m
subtract 3 from both sides
9 < 1.80m
divide both sides by 1.80
5 < m
ANSWER: They can travel 5 miles on $12.
Hope this helps! :)

$50(0.80)
Answers
$50(0.80)
$50(0.80) = $40 discounted amount
$50 * 20% = 10 discount value
$50 - 10 = $40 discounted amount
$50 - 20% of $50 = $50 - 20% * $50 = $50 - 20/100 * $50 = $50 - 1/5 * $50 = $50 - 0.20 * $50 = $50 * 0.80 = $40
The correct result would be $50(0.80).

The standard deviation (sd or σ) of the sample mean difference is:
sd = √(sd₁²/n₁ + sd₂²/n₂)
For the population A:
sd₁ = 17.6
n₁ = 25
For the population B:
sd₂ = 21.2
n₂ = 30
Hence:
sd = √(sd₁²/n₁ + sd₂²/n₂)
= √(17.6²/20 + 21.2²/30)
= √(309.76/20 + 449.44/30)
= √(15.49 + 14.98)
= √(30.47)

Answer:
-63
Step-by-step explanation:
Because -9 x 7 = -63. If the signs are different then it will be negative. -9 x 7 = -63 is the same like 9 x 7 = 63. I hope this answer your question!

Answer: it take 5.448 years for the population to reach one million.
Step-by-step explanation:
The population of a city is modeled by the equation
P(t) = 256,114e0.25t
where t is measured in years.
For the population to reach 1000000, it means that
1000000 = 256114e0.25t
1000000/256114 = e0.25t
3.9045 = e0.25t
Taking ln of both sides of the equation, it becomes
Ln 3.9045 = Ln e0.25t
1.362 = 0.25t
t = 1.362/0.25
t = 5.448 years
Final answer:
The city's population is modeled by an exponential function and to find when the population will reach one million, we need to solve the equation for t by setting P(t) = 1,000,000. This requires dividing by the initial population, taking the natural logarithm, and then dividing by the growth rate (0.25). The result is the time in years it takes for the city's population to reach one million.
Explanation:
Calculation of Population Growth Time
The city's population growth is modeled by an exponential function, P(t) = 256,114e0.25t. Here, P(t) is the population at time t and 'e' is Euler's number, approximately equal to 2.71828. Your goal is to find when the population reaches one million.
To do this, set P(t) = 1,000,000 and solve for t:
1,000,000 = 256,114e0.25t
You would divide both sides by 256,114 and then take the natural logarithm to isolate t:
t = ln(1,000,000 / 256,114) / 0.25
Use a calculator to solve for 't'. This gives the time in years it takes for the city's population to reach one million people. It's a clear demonstration of how exponential growth operates: as the population increases, it takes less time to add a certain number of individuals.
