Ann and Ben translate documents from German into English.
A set of documents that would take Ann 10 days would take Ben 12 days.
Ann starts to translate the documents
After 2 days Ann and Ben both work or translating the documents.
How many MORE days will it take to complete the work?
Give answer in mixed fraction
The additional number of days that is required to complete the rest of the work in mixed fraction is equal to 4 4/11 days.
How to determine the additional number of days?First of all, we would determine the number of work left for Ann after two (2) working days:
In one (1) day, the amount of work that would be done by Ann alone is given by 1/10 days. Therefore, the amount of work that would be done by Ann alone in two (2) days is given by 2/10 or 1/5 days.
For the number of work left, we have:
Work left = 1 - 1/5
Work left = 4/5 days.
Similarly, the amount of work that would be done by Ben alone in one (1) day is given by 1/12 days.
Therefore, the combined work rate of both Ann and Ben is given by:
Combined work rate = 4/5 + 1/12
Combined work rate = 11/60
For the additional number of days required to complete the rest of the work, we have:
Additional days = 4/5 ÷ 11/60
Additional days = 4/5 × 60/11
Additional days = 4 × 12/11
Additional days = 48/11
Additional days = 4 4/11 days.

The path of a baseball is modeled by the equation [tex]y= -0.25x^{2} +4x+3\\[/tex] where x represents the time (in seconds) and y represents the height of the baseball.
- Find and interpret the y-intercept. Find the maximum height of the baseball. Then sketch a graph of the path.
(please provide steps on how to solve if you can)
The y-intercept is y = 3, and this is the initial height of the ball, and the maximum height is y = 19
What is the y-intercept?The y-intercept is what we get when we evaluate in x = 0, then:
y = -0.25*x² + 4x + 3
replacing x by zero we get:
y = -0.25*0² + 4*0 + 3 = 3
The y-intercept is y = 3.
The maximum height is at the vertex, we know this because the leading coefficient is negative, which means that the parabola opens down.
The vertex is at:
x = -4/(2*-0.25) = 8
Evaluating there:
y = -0.25*8² + 4*8 + 3 = 19
that is the maximum height.

The materials travel faster on Belt One, considering the constants of the proportional relationships.
What is a proportional relationship?A proportional relationship is a linear function with intercept zero in which the output variable symbolized by y is given by the multiplication of the input variable symbolized by x and the constant of proportionality symbolized by k, according to the equation presented as follows:
y = kx
For each belt in this problem, the constant gives the velocity that the materials travel.
For Belt One, the relation is:
y = 157.1x.
Hence the velocity is of 157.1 inches per minute.
For Belt Two, the velocity is obtained as follows:
k = 125.6/2 = 62.8 inches per minute.
157.1 > 62.8, hence it travels faster on Belt One.

What is Linear Inequality?
The mathematical expression with unequal sides is known as inequality in mathematics. Inequality is referred to in mathematics when a relationship results in a non-equal comparison between two expressions or two numbers. In this instance, any of the inequality symbols, such as greater than symbol (>), less than symbol (), greater than or equal to a symbol (), less than or equal to a symbol (), or not equal to a symbol (), is used in place of the equal sign "=" in the expression. Polynomial inequality, rational inequality, and absolute value inequality are the various types of inequalities that can exist in mathematics. The symbols "" and ">" signify tight inequalities, while "" and "" signify slack inequalities.

To mix a particular shade of purple paint, red paint and blue paint are mixed in the ratio . To make 20 gallons of this shade of purple paint, how many gallons of red and blue paint should be used?
Answer:
Red paint = 12.5 gallons
Blue paint = 7.5 gallons
Step-by-step explanation:
The given ratio of red paint to blue paint is:
red : blue = 5 : 3Let x be the number of gallons of purple paint.
Therefore, the expression for each color of paint needed per x gallons of purple paint is:
[tex]\implies \textsf{Red\;paint $=\dfrac{5}{8}x$}[/tex]
[tex]\implies \textsf{Blue\;paint $=\dfrac{3}{8}x$}[/tex]
To calculate the number of gallons of red and blue paint needed to make 20 gallons of purple paint, substitute x = 20 into the found expressions:
[tex]\implies \textsf{Red\;paint $=\dfrac{5}{8} \times 20=\dfrac{100}{8}=12.5$}[/tex]
[tex]\implies \textsf{Blue\;paint $=\dfrac{3}{8}\times 20=\dfrac{60}{8}=7.5$}[/tex]

y=3x-1 passes through (3,2)
The equation of the line passing through y = 3x-1 and (3,2) is y = 3x-7.
According to the question,
We have the following information:
y = 3x-1 and the point through which line is passing is (3,2)
We know that the slope of the given line (denoted by m) is 3.
Now, the following formula is used to find the equation of the line passing through a point:
y-y' = m(x-x')
In this case, we have x' = 3 and y' = 2.
y-2 = 3(x-3)
y-2 = 3x-9
Moving 2 from the left hand side to the right hand side will result in the change of the sign from minus to plus:
y = 3x-9+2
y = 3x-7
Hence, the equation of the line passing through y = 3x-1 and (3,2) is y = 3x-7.

What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
1) Now, put (x1, y1)=(2, 6.85) and (x2, y2)=(4, 7.55) in slope formula, we get
m=(7.55-6.85)/(4-2)
= 0.7/2
= 0.35
Substitute m=0.35 and (x, y)=(2, 6.85) in y=mx+c, we get
6.85=0.35(2)+c
⇒ 6.85=0.7+c
⇒ c=6.85-0.7
⇒ c=6.15
Now, equation is y=0.35x+6.15
2). Put x=15 in the obtained equation, we get
y=0.35×15+6.15
⇒y=$11.4
3). Put y=9.65 in the obtained equation, we get
9.65=0.35x+6.15
