By what percent will the fraction change if its numerator is
increased by 25% and its denominator is increased by 20%?
Answer:
The fraction increase by ( [tex]0.047=4.7\:\%[/tex] ) if its numerator is
increased by 25% and its denominator is increased by 20%.
Step-by-step explanation:
Let 'n' be the numeratorLet 'd' be the denominatorAs
[tex]100\%\mathrm{\:in\:fractions}=\:1[/tex]
[tex]25\%\mathrm{\:in\:fractions}=\:\frac{1}{4}[/tex]
[tex]20\%\mathrm{\:in\:fractions}=\frac{1}{5}[/tex]
so
Increase in 25% means
[tex]100\%\:+25\%\:=\frac{5}{4}[/tex]
Increase in 20% means
[tex]100\%\:+20\%\:=\frac{6}{5}[/tex]
Thus the fraction becomes
[tex]\:\frac{\frac{5}{4}\times \:n}{\frac{6}{5}\times \:d}[/tex]
[tex]=\frac{\frac{5}{4}n}{\frac{6d}{5}}[/tex]
[tex]\mathrm{Divide\:fractions}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\times \:d}{b\times \:c}[/tex]
[tex]=\frac{5n\times \:5}{4\times \:6d}[/tex]
[tex]=\frac{25n}{24d}[/tex]
[tex]=1.0417\left(\frac{n}{d}\right)[/tex]
[tex]=1\left(\frac{n}{d}\right)+0.047\left(\frac{n}{d}\right)[/tex]
As
[tex]0.047=4.7\:\%[/tex]
Therefore, the fraction increase by ( [tex]0.047=4.7\:\%[/tex] ) if its numerator is
increased by 25% and its denominator is increased by 20%.

Which of the following equations represents a line that is parallel to the line that passes through the points below?
(-3,6) (9,2)
Answer:
See below
Step-by-step explanation:
Two lines are parallel if they have the same slope but different y-intercepts. So the slope that can be formed given the points (-3,6) and (9,2) is (9-(-3))/(2-6)=12/-4=-3
With y=-3x+b, we need b, which can be found by plugging in either point:
2=-3(9)+b
2=-27+b
29=b
So the y-intercept therefore cannot be 29 but it can be any real number.
So the equation y=-3x+2 works, y=-3x+3, y=-3x+4, and so on....
choose the function whose graph is given by:
Answer:
A
Step-by-step explanation:
I put the equation into a GeoGebra graphing calculator, and y=sin(x-2) matches the graph.
The function represents the given graph is y = sin(x - 2).
What is the translating a graph?"Translating a graph means that moving it along the x or y axis by certain units."
Translating a function y = f(x):1) For a function of the type y = f(x) + k
If k > 0, the graph of y = f(x) will translate up(along positive Y-axis) by k units.
If k < 0, the graph of y = f(x) will translate down(along negative Y-axis) by k units.
2) For a function of the type y = f(x + m)
If m > 0, the graph of y = f(x) will translate left(along negative X-axis) by m units.
If m < 0, the graph of y = f(x) will translate right(along positive X-axis) by m units.
From given example,
The function represents the given graph is y = sin(x - 2).
This means, the function y = sin(x) is translated right by angle 2 (degrees / radians) as shown in the following figure.

18) Write an equation of the line that is perpendicular to the line y = 4x - 10 that passes through the point (-16, 2). A) y = - 1 4 x - 2 B) y = -4x + 6 C) y = - 1 4 x + 2 D) y = 4x + 2
The equation of the line that is perpendicular to y = 4x - 10 and passes through the point (-16, 2) is y = -1/4x - 2, which is option A.
Explanation:The student is asking for the equation of a line that is perpendicular to the given line y = 4x - 10 and passes through the point (-16, 2). The slope of the given line is 4, and the slope of a line perpendicular to it will be the negative reciprocal, which is -1/4. Using the slope-intercept form of a line, y = mx + b, where m is the slope and b is the y-intercept, we substitute the slope -1/4 and the point (-16, 2) to find b.
Plugging in the point, we get:
2 = (-1/4)(-16) + b
2 = 4 + b
b = 2 - 4
b = -2
So, the equation of the line is y = (-1/4)x - 2. The correct answer is option A) y = -1/4x - 2.
To find the line perpendicular to ( y = 4x - 10 ) passing through (-16, 2), its equation is[tex]\( y = -\frac{1}{4}x - 2 \)[/tex], option A.
The correct option is a)[tex]\(y = -\frac{1}{4}x - 2\).[/tex]
To find the equation of the line that is perpendicular to the given line (y = 4x - 10), we first need to determine the slope of the given line, because perpendicular lines have slopes that are negative reciprocals of each other.
The given line (y = 4x - 10) is in the slope-intercept form (y = mx + b), where (m) is the slope. In this case, the slope of the given line is (m = 4).
The negative reciprocal of (4) is [tex]\(-\frac{1}{4}\)[/tex]. This will be the slope of the perpendicular line.
Now, we use the point-slope form of a line, which is [tex]\(y - y_1 = m(x - x_1)\),[/tex]where [tex]\((x_1, y_1)\)[/tex] is a point on the line and \(m\) is the slope.
Given the point ((-16, 2)), we substitute (x_1 = -16) and (y_1 = 2) into the point-slope form and the slope[tex]\(m = -\frac{1}{4}\):[/tex]
[tex]\[ y - 2 = -\frac{1}{4}(x - (-16)) \][/tex]
[tex]\[ y - 2 = -\frac{1}{4}(x + 16) \][/tex]
Now, we can simplify and rewrite this equation in slope-intercept form (y = mx + b):
[tex]\[ y - 2 = -\frac{1}{4}x - 4 \][/tex]
[tex]\[ y = -\frac{1}{4}x - 4 + 2 \][/tex]
[tex]\[ y = -\frac{1}{4}x - 2 \][/tex]
So, the equation of the line that is perpendicular to (y = 4x - 10) and passes through the point ((-16, 2)) is option A) [tex]\(y = -\frac{1}{4}x - 2\).[/tex]

105 = 10 x 10 x 10 x 10 x 10 = 100,000 (5 zeros)
108 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 100,000,000 (8 zeros)
Notice that the number of zeros in the ordinary decimal expression is exactly equal to the power to which 10 is raised.
If the number is expressed in words, first write it down as an ordinary decimal number and then convert. Thus, "ten million" becomes 10,000,000. There are seven zeros, so in powers of ten notation ten million is written 107.
A number which is some power of 1/10 can also be expressed easily in scientific notation. By definition,
1/10 = 10-1 ("ten to the minus one power")
More generally, the expression "10-n" (where n is a whole number) means ( 1/10 )n. Thus
10-3 = ( 1 / 10 )3 = 1 / ( 10 x 10 x 10) = 1/1000
10-8 = ( 1 / 10 )8 = 1/100,000,000
In a French class, there are 10 freshmen, 8 sophomores, and 2 juniors. Of these students, 9 freshmen, 2 sophomores, and 1 junior are female. A student is selected at random. P(freshman or sophomore)
The probability of selecting a freshman or a sophomore from the French class is 0.9 or 90%. The probability of selecting a freshman or a sophomore from the French class can be found by dividing the total number of freshmen and sophomores (18) by the total number of students (20). The probability is calculated as 18 / 20, which simplifies to 0.9 or 90%.
To find the probability of selecting a freshman or a sophomore from the French class, we need to calculate the total number of freshmen and sophomores and divide it by the total number of students.
Step 1: Calculate the total number of freshmen and sophomores.
The total number of freshmen is 10, and the total number of sophomores is 8. Adding these two numbers together, we get 10 + 8 = 18.
Step 2: Calculate the total number of students.
The total number of freshmen, sophomores, and juniors is given as 10 + 8 + 2 = 20.
Step 3: Calculate the probability.
The probability of selecting a freshman or a sophomore can be calculated by dividing the total number of freshmen and sophomores (18) by the total number of students (20).
P(freshman or sophomore) = Number of freshmen and sophomores / Total number of students
P(freshman or sophomore) = 18 / 20
P(freshman or sophomore) = 0.9
Therefore, the probability of selecting a freshman or a sophomore from the French class is 0.9 or 90%.
The question probable may be:
What is the probability of selecting a freshman or a sophomore from the French class, and how is this probability calculated using the total number of freshmen and sophomores divided by the total number of students?
In a French class, there are 10 freshmen, 8 sophomores, and 2 juniors. Of these students, 9 freshmen, 2 sophomores, and 1 junior are female. A student is selected at random. P(freshman or sophomore)

Elsa saving money to buy a game so far she had saved $36 which is 3/4 of the total cost of the game how much does the game cost
Answer:
$48
Step-by-step explanation:
To figure out how much the game costs in total, we first need to divide $36 by 3 (3 is the numerator).
36 / 3 = 12
The number 12 is how much each quarter is worth as shown below.
1/4 = 12
2/4 = 24
3/4 = 36
4/4 = ?
To find the answer, all we do is add 12 to 36.
12 + 36 = $48
Answer:
$48
Step-by-step explanation:
Let x represent the cost of the game
$36 = 3/4 x
Divide both sides by 3/4
$36/3/4 = x
$36 *4 / 3 = x
$48 = x
Therefore, the game costs $48
