In the early months of some year, one site added 0.2 million new accounts every day. at this rate, how many days would be needed to add 10million new accounts?
Answer:
50 days
Step-by-step explanation:
It's simple, we just have to express this as an equation.
x we will take it as the number of days we do not know.
so..
(0.2 M * x) = 10 M
we divide on both sides by 0.2 M.
x * 0.2 M / 0.2M = 10 M / 0.2 M
we simplify
x = 10M / 0.2 M
finally we only solve and the result of x will be the days it took.
x = 50
50 days
Andrea's family stopped at the gas station to get gas. At gas stations, the price of gas per gallon is given to the nearest thousandth. In order to determine how much money he would need to pay for the gas, Andrea's dad asked her to round the price of gas per gallon to the nearest hundredth. The gas price per gallon rounded to the nearest hundredth was $2.50. Which of the following prices could have been the original gas price?

The set {0, 1} is closed under which operation? (Points : 3)
addition
multiplication
subtraction
none of the above
The set {0,1} is closed under both addition and multiplication, but not under subtraction. Closed means that any operation between any two elements in the set produces another element in the set.
Explanation:The set {0,1} is closed under both addition and multiplication. This means that if you perform either of these operations on any two numbers from the set, the result is a number that is also within the set.
For example if you add 0 and 1 (0+1), or multiply them (0*1), the result (1 and 0 respectively) is still within the set {0,1}. However, the set is not closed under subtraction, because 0-1 gives -1, which is not in the set.

How do i graph:
x – 3y = –12
2x – y = 1
...?
To graph the given linear equations, convert them to slope-intercept form and plot their y-intercepts and slopes on a graph to draw the lines representing each equation.
Explanation:To graph the equations:
x − 3y = − 12
2x − y = 1
You can use the following steps:
Rearrange each equation into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.For the first equation, solve for y: y = (1/3)x + 4. For the second equation, y = 2x − 1.Plot the y-intercept of each line on the graph. For the first equation, the y-intercept is 4. For the second equation, the y-intercept is -1.Use the slope to determine another point on each line. For the first equation, from the y-intercept (0,4), go up 1 unit and right 3 units to plot another point. For the second equation, from the y-intercept (0,-1), go up 2 units and right 1 unit to plot another point.Draw a straight line through the points for each equation. These lines represent the equations on the graph.By following these steps, you will produce a graph with two lines, which could intersect at a point that represents the solution to the system of equations.
To graph the system of equations x - 3y = -12 and 2x - y = 1, convert each to slope-intercept form, plot the y-intercepts, use the slopes to determine another point for each line, and draw the lines through these points.
Explanation:To graph the system of equations given by x – 3y = –12 and 2x – y = 1, you need to follow these steps:
First, rearrange each equation into slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.For the first equation x – 3y = –12, solving for y gives us y = \frac{x}{3} + 4.For the second equation 2x – y = 1, solving for y gives us y = 2x – 1.Once the equations are in slope-intercept form, you can plot the y-intercept of each line on the y-axis, which are (0, 4) for the first equation and (0, –1) for the second equation.Then, use the slope to determine another point for each line. For the first line with a slope of \frac{1}{3}, you can move right 3 units and up 1 unit from the y-intercept. For the second line with a slope of 2, move right 1 unit and up 2 units.Draw lines through the points you have plotted for each equation. The point where the lines cross is the solution to the system of equations.With consistent practice, graphing systems of equations can become a more straightforward process.

Simplify the complex fraction .
[(2)/(5t) - (3)/3t)]/[(1)/(2t) + (1)/(2t)]
Answer:
The simplified form of the given expression [tex]\dfrac{\frac{2}{5t}-\frac{3}{3t} }{\frac{1}{2t}+\frac{1}{2t}}=-\frac{3}{5}[/tex]
Step-by-step explanation:
Given expression [tex]\dfrac{\frac{2}{5t}-\frac{3}{3t} }{\frac{1}{2t}+\frac{1}{2t} }[/tex]
We have to simplify the given expression [tex]\dfrac{\frac{2}{5t}-\frac{3}{3t} }{\frac{1}{2t}+\frac{1}{2t} }[/tex]
Consider the given expression [tex]\dfrac{\frac{2}{5t}-\frac{3}{3t} }{\frac{1}{2t}+\frac{1}{2t} }[/tex]
Consider denominator [tex]\frac{1}{2t}+\frac{1}{2t}[/tex]
Apply rule, [tex]\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]
[tex]=\frac{1+1}{2t}=\frac{1}{t}[/tex]
Now, apply fraction rule, [tex]\frac{a}{\frac{b}{c}}=\frac{a\cdot \:c}{b}[/tex]
We get,
[tex]=\frac{\left(\frac{2}{5t}-\frac{3}{3t}\right)t}{1}[/tex]
Simplify, we get,
[tex]\frac{t\left(\frac{2}{5t}-\frac{1}{t}\right)}{1}[/tex]
Simplify, we get,
[tex]\frac{t\left(\frac{2}{5t}-\frac{1}{t}\right)}{1}[/tex]
Further simplify by [tex]\frac{-a}{b}=-\frac{a}{b} \ and\ a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]
We get, [tex]=-\frac{3t}{5t}[/tex]
Thus, [tex]-\frac{3}{5}[/tex]

f(x)=
The sinusoidal function described in the question is a cosine function that has been shifted vertically by 5 units. This can be written in the form f(x) = cos(x - π) + 5.
Explanation:In the given question, we are told that a sinusoidal function intersects its midline at (0,5) and has a maximum point at (π,6). Since the function reaches its maximum at π, it implies that this is a cosine function which shifted 5 units up on the y axis.
The general form for a cosine function is f(x) = A cos(Bx - C) + D, where: A is the amplitude of the wave, B determines the period of the wave, C is the phase shift, and D is the vertical shift. Given that we reach a maximum at (π,6), the amplitude is 1 (since it rises 1 unit above the midline). The vertical shift is 5, as the function crosses at (0,5).
Considering these factors and that the function hits a maximum (as opposed to a minimum) at x = π, we can say that the cosine's phase shift is π. Thus, the function does not need to be horizontally shifted. Therefore, the function is f(x) = cos(x - π) + 5.
