Ans: 0.027, 1/6, 23%, 0.29, 3/5
To arrange the numbers 1/6, 0.29, 23%, 3/5, and 0.027 from smallest to largest, convert them to decimals and then compare. The order from smallest to largest is: 0.027, 1/6 (0.166...), 23% (0.23), 0.29, and 3/5 (0.6).
Explanation:
To arrange the numbers 1/6, 0.29, 23%, 3/5, and 0.027 from smallest to largest, we first need to convert them all to the same format. We can convert percentages to decimals by dividing by 100 and fractions to decimals by division. Here are the conversions:
1/6 = 0.166...0.29 (already a decimal)23% = 0.233/5 = 0.60.027 (already a decimal)Now that they are all in decimal form, we can easily compare them:
0.027 (smallest)1/6 (or 0.166...)23% (or 0.23)0.293/5 (or 0.6, largest)for what values of x will the result of 5x be greater than 1

the average cost of regular gasoline in north carolina increased by 73% from 2006 to 2007. If the average cost of a gallon of gas in 2006 was %2.069, what was the average cost in 2007?
Answers
The average cost of regular gasoline in North Carolina increased by 73% from 2006 to 2007. Therefore, if the average cost in 2006 was $2.069, it increased by approximately $1.51 to about $3.58 per gallon in 2007.
Explanation:The subject of this question is a real-world application of the concept of percentage increase in mathematics. To calculate the average cost of regular gasoline in North Carolina in 2007, we use the given fact that it increased by 73% from 2006 to 2007. If the average cost in 2006 was $2.069,
First, find out what the 73% of $2.069 is. We do this by multiplying 2.069 by 73/100: 2.069*(73/100) = $1.51037.
Next, add the number you found above to the original 2006 price: $2.069 + $1.51037 = $
3.57937
.
So the average cost of regular gasoline in 2007 in North Carolina was approximately $3.58 per gallon (rounding to the nearest cent).

If a person weighs 240 pounds on Earth, what would be the difference in weight of the same person on Mars and on the Moon (based on the table and graph)?
Answers
Answer:
C
Step-by-step explanation:
The person weighs 560 more on Mars than on the moon.
On comparing the weight of the individual on Earth, Mars and Moon, we concluded -
W[Earth] > W[Mars] > W[Moon]
What is Weight ?
Weight is the force exerted by the earth on an object at the surface of the earth. Mathematically -
W = m x g
where -
[m] is the mass of object
[g] is acceleration due to gravity
Given is a person who weighs 240 pounds on Earth.
The weight of the individual in kg m/s² (Newtons) on earth would be -
W[Earth] = 240 x 0.45359237 x 9.8 = 1066.84 N
The weight of the same individual on mars would be -
W[Mars] = 240 x 0.45359237 x 3.11 = 333.56 N
The weight of the same individual on moon would be -
W[Moon] = 240 x 0.45359237 x 1.625 = 176.90 N
Therefore, we can conclude that W[Earth] > W[Mars] > W[Moon].

A model for the path of a toy rocket is given by h= -68t - 4.9t^2
How long does it take the rocket to hit the ground? How high was the rocket at 2 seconds? What is the maximum height of that rocket and how long does it take that rocket to reach it's maximum height?
Answers
I will show you the solution using h = 68t - 4.9t^2
1) How long does it take the rocket to hit the ground?
ground level => h = 0
=> 68t - 4.9t^2 = 0
factor the polynomial => - t (4.9t - 68) = 0
=> t = 0 (which is when the rocket takes off) and 68 + 4.9t = 0 (which is when the rocket to return and hit the ground).
4.9t - 68 = 0 => t = 68 / 4.9 = 13.88 s
Answer: 13.88 s
2) How high was the rocket at 2 seconds?
replace t = 2 in the function h = - 4.9t^2 + 68
=> h = -4.9 (2^2) + 68 = 48.4 m
Answer: 48.4 m
3) What is the maximum height of that rocket and how long does it take that rocket to reach it's maximum height?
Find the vertex of the parabola.
You should know that the vertex is at the midpoint between the two roots (zeros of the polynomial).
You already found the zeros, t = 0 and t = 13.88
So0 the vertex is at t = [0 + 13.88] / 2 = 6.94 s
And the maximum height is h = - 4.9 (6.94)^2 + 68 = 168 m
Answer: h max = 168 m, t = 6.94 s.
The duration for the rocket to hit the ground, its height at 2 seconds, and its maximum height can be calculated using the given quadratic equation for height over time. The maximum height is determined by finding the vertex of the parabola.
Explanation:To determine how long it takes the toy rocket to hit the ground, we need to set the equation for height h to zero and solve for time t. The model for the path of a toy rocket is given by [tex]h = -16t2 - 4.9t2[/tex]. To solve for t, we factor the right side:
[tex]h = -4.9t(16 + t)[/tex]
Since h = 0 when the rocket hits the ground, we set [tex]-4.9t(16 + t) = 0[/tex] and solve for t. There are two solutions: t = 0 (when the rocket is launched) and the positive solution which is when the rocket hits the ground. We disregard the solution t = 0 and solve for the positive solution to find out how long it takes to hit the ground.
To find out how high the rocket was at 2 seconds, we simply plug t = 2 into the original equation:
[tex]h = -16(2)2 - 4.9(2)2[/tex]
And solve for h to get the height at 2 seconds.
To determine the maximum height of the rocket, we need to find the vertex of the parabola represented by the given equation, which is a quadratic function of t. Since the coefficient in front of t2 is negative, the vertex will give us the maximum height. The time it takes to reach the maximum height is given by t = -b/2a, where a and b are coefficients from the equation [tex]h(t) = at2 + bt + c.[/tex] In this case, a = -4.9 and b = -68.
The calculations must be done to find the precise values for the time to hit the ground, the height at 2 seconds, and the maximum height of the rocket, along with the time it takes to reach it.

Maggie’s brother is 6 years younger than three times her age. The sum of their ages is 42. How old is Maggie?
Answers
y = The brother's age
x + y = 42
y = 3x - 6
Using the substitution property, we can replace y in the first equation with the 3x - 6 in the second equation like so:
x + (3x - 6) = 42
Then solve this equation for x like so:
x + (3x - 6) = 42
x + 3x = 48 (Add 6 to both sides)
4x = 48 (Simplify)
x = 12 (Divide both sides by 4)
This shows that Maggie's is 12 years old. In order to prove this, you must check your work. In order to do this, first plug your answer back into the original equation like so:
x + y = 42
12 + y = 42. (Plug in answer)
y = 30 (Subtract both sides by 12)
This shows that Maggie's brother is 30 years old. The final step to proving this is to plug both of your answers into the second equation to make sure that your answers are within the constraints set by the problem. Do this like so:
y = 3x - 6
30 = 3(12) - 6 (Plug in answers)
30 = 36 - 6 (Simplify)
30 = 30 (Simplify)
Because the equation is balanced, your answers are correct. So, to answer your question, Maggie is 12 years old.
