Answer:
234 miles
Step-by-step explanation:
Lets set the variable 'n' as the number of miles driven. We can set up the following equation:
18.95 + 0.83n = 213.17
Now, all we have to do is solve it. We can get 0.83n = 194.22, so n = 194.22/0.83 = 234 miles
find p if (p, 2p+1) is solution of 11x-2y=5
Answer:
p = 1
Step-by-step explanation:
since (p, 2p + 1) is a solution then it makes the equation true.
substitute x = p and y = 2p + 1 into the equation and solve for p
11p - 2(2p + 1) = 5 ← distribute parenthesis and simplify left side
11p - 4p - 2 = 5
7p - 2 = 5 ( add 2 to both sides )
7p = 7 ( divide both sides by 7 )
p = 1

Kelly can run 1/2 mile in 3 minutes. How far does
Kelly run in 1 minute if he runs at the same pace the
entire time?
Kelly can run 1/2 mile in 3 minutes. 1/6 mile Kelly run in 1 minute if he runs at the same pace the entire time.
What makes anything a mile?The word "mile" is derived from the Latin "mille passus," which means "one thousand paces." The English Parliament established the Mile at eight furlongs (one furlong is 660 feet) in 1592. A mile is a unit of measurement that is standardised as exactly 1609.344 metres by the International agreement in 1959. A mile is exactly equivalent to 5280 feet, or 1760 yards.
Kelly can run 1/2 mile in 3 minutes so the ratio is 1/2 mile per 3 minutes

China’s steel production is increasing while its major competitors’ production is declining. By 2009, China’s tons of steel produced per US million ($) GDP was 50, about 10 tons less than Japan’s all-time high. At 50 tons of steel produced per US million ($) GDP, China has the highest steel production of all producers shown as of 2009.
The most accurate comment about the graph data is: "China's steel production is increasing while its major competitors' production is declining."
A graph is what?Academics are using graphs to logically chart or graphically depict events or quantities. A graph point is a common way to depict how different things interact. The non-linear storage structure known as a graph is made up of nodes, also referred to as vertices, and lines. Glue ought to be used to connect the edges, also known as nodes , respectively. (4.5).
Here,
The most accurate comment about the data is: "China's steel production is increasing while its major competitors' production is declining."
This is because the graph shows that China's steel production has been steadily increasing since the early 2000s, while the steel production of other major producers such as Japan, the United States, and Germany has been declining or stagnant. This trend is particularly evident after the global financial crisis of 2008-2009.
While it is true that Japan's steel production has increased and shows no signs of decreasing, this comment does not address the overall trend of declining steel production among major producers.
The other two comments are not accurate. The statement "By 2009, China’s tons of steel produced per US million ($) GDP was 50, about 10 tons less than Japan’s all-time high" is not supported by the graph, as there is no information about tons of steel produced per US million ($) GDP on the graph.

~[tex]\frak{Amphitrite1040:)}[/tex]A salesperson earned a commission of
$806.59
last week on gross sales of
$5880
. If returns and allowances were 11.5% of gross sales, what is his rate of commission based on net sales?
Using percentages we know that the rate of commission of the salesperson based on the net sales is 15.5%.
What are percentages?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and sometimes "pc" is also used, the percent symbol, "%," is frequently used to indicate it.
A % is a number without boundaries and without a standard measurement.
So, calculate as follows:
5880/100 * 11.5 = 676.2
Now,
5880 - 676.2 = 5,203.8
Now, calculate the percentage as follows:
806.59/5,203.8 * 100
15.5%
Therefore, using percentages we know that the rate of commission of the salesperson based on the net sales is 15.5%.

Find the principal value of Arctan (-1.44) to the nearest minute.
Answer: To find the principal value of arctan(-1.44) to the nearest minute, we first need to find the value of arctan(-1.44) in radians.
We can use the arctan function in a mathematical software or calculator to find the result. The value of arctan(-1.44) in radians is approximately -0.8623.
Next, we convert the result from radians to minutes, by multiplying the radians by 180/π and then multiplying the result by 60.
-0.8623 * 180/π * 60 = -50.47 minutes
So the principal value of arctan(-1.44) to the nearest minute is approximately -50 minutes.

What is the equation of the function that is graphed as line a?
y = 4 x - 3
y = - 1/4 x + 3
y = 1/4x + 3
y = -4 x - 3
Answer:
y = 4x - 3
Step-by-step explanation:
y = mx + b
The m is the slope and the b is the y-intercept.
The slope is 4. If you start at the point (0,-3) and go up 4 units and then 1 unit to the right, you will be back on the line at point (2,4) The slope is the rise over the run. The rise is 4 and the run is 1. 4/1 = 4.
The slope (m) is 4.
The y-intercept is where the line crosses the y axis. It crosses at (0,-3)
The y-intercept (b) is -3
Plug 4 in for m and -3 in for b
y = mx + b
y = 4x -3
Answer:
[tex]y = 4x - 3[/tex]
Step-by-step explanation:
we need to find out the equation of the function that is graphed. From the given graph we can see that the line passes through points (0,-3) and (2,5) . So we can find out the slope of the line as ,
[tex]\implies m =\dfrac{y_2-y_2}{x_2-x_1}=\tan\theta\\[/tex]
[tex]\implies m =\dfrac{-3-5}{0-2} \\[/tex]
[tex]\implies m =\dfrac{-8}{-2} \\[/tex]
[tex]\implies \mathfrak{ m = 4 }\\[/tex]
Now we may use point slope form of the line to find out the equation of the line as,
[tex]\implies y - y_1 = m(x-x_1) \\[/tex]
[tex]\implies y -(-3) = 4(x-0) \\[/tex]
[tex]\implies y +3 = 4x\\[/tex]

Zachary purchased a computer for $1,300 on a payment plan. Two months after he purchased the computer, his balance was $1,090. Seven months after he purchased the computer, his balance was $565. What is an equation that models the balance y after x months?
The equation ______ models the balance y after x months.
(Type your answer in slope-intercept form. Use integers or fractions for any numbers in the equation. Do not include the $ symbol in your answer.)
Answer:
[tex]y=-105x+1300[/tex]
Step-by-step explanation:
Define the variables:
Let x be the number of months after Zachary purchased a computer.Let y be the balance of the payment plan (in dollars).Given information:
Purchase price of the computer = $1,300Balance = $1,090 after 2 months.Balance = $565 after 7 months.Therefore:
x = 0, y = 1300x = 2, y = 1090x = 7, y = 565[tex]\boxed{\begin{minipage}{8cm}\underline{Slope Formula}\\\\Slope $(m)=\dfrac{y_2-y_1}{x_2-x_1}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.\\\end{minipage}}[/tex]
Determine if the equation is linear by calculating the slope between each pair of (x, y) points:
[tex]\implies \text{Slope}\;(m)=\dfrac{565-1090}{7-2}=-105[/tex]
[tex]\implies \text{Slope}\;(m)=\dfrac{1090-1300}{2-0}=-105[/tex]
As the slope is the same, the equation is linear.
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
The initial purchase price of the computer was $1,300. So when x = 0, y = 1300. Therefore, the y-intercept is 1300.
We have already calculated the slope as -105.
Substitute the found slope and y-intercept into the slope-intercept formula to create an equation that models the balance y after x months:
[tex]y=-105x+1300[/tex]

be 0.5% per year. Given a 2001 population size of about 285 million, calculate the projected
population size in 2025. Use the exponential growth equation (N= No e"), to calculate the
population. In the equation, No is the initial population (285,000,000), r is the growth rate expressed as a
decimal (0.005), t is the number of years (25), e is a constant (defined as the base of the natural
logarithm), and N, is the population after t years.
In 2025, we would have 321 million people Since we do have an exponential growth function here.
What is exponential growth?
Exponential growth is a type of growth that occurs when the rate of increase is proportional to the current value. In mathematical terms, it can be expressed as y = ab^x.
We then have that;
P = Poe^rt
P = population at time t
Po = Initial population
r = rate of growth
t = time taken
Then;
t = 24 years
r = 0.005

Expression: What is it?In mathematics, addition, multiplication, and division are necessary. They result in the following when combined: An equation, some data, and a mathematical function Values, parameters, and mathematical operations like additions, subtractions, multiplications, and divisions can all be found in a declaration of fact. Different phrases and words can be compared and evaluated.
Here,
To prove that the value of the expression doesn't depend on x, we need to show that the x-term disappears when we simplify the expression.
Starting with:
(3/5x² - 0.4cy - 1.5y + 1) - (y² - 2/5xy + 0.6x²)
Distributing the negative sign in the second set of parentheses:
3/5x² - 0.4cy - 1.5y + 1 - y² + 2/5xy - 0.6x²
Rearranging the terms by collecting like terms, we get:
(3/5 - 0.6)x² + (2/5y - 0.4c)y - y²- 1.5y + 1
Simplifying further, we get:
(-0.1)x² + (0.4y - 0.4c)y - (y² + 1.5y - 1)
Notice that there is no x-term in the final expression, which means that the value of the expression doesn't depend on x.
Therefore, we have proved that the value of the expression (3/5x²-0.4cy-1.5y+1)-(y²-2/5xy+0.6x²) doesn't depend on x.

so our "x" went up by 0.1025x, now let's conver that to a percent, 0.1025 * 100 = 10.25%.
