What is a fraction?A fraction represents a part of a number or any number of equal parts.
We are given that Ian has 120 folders to file. So far, he has filed 36 of the folders.
The fraction of the amount of folders Ian did not file out of 120 ;
84/120
= 21/30
In order to convert this into a percent, we have to divide both the numerator and the denominator by 1.2.
we will get 70/100.
This new fraction as a percent is 70%.
Therefore, he has 70% of folders left to file.

Further explanationSimultaneous Linear Equations can be solved using one of the following methods :
Elimination MethodSubstitution MethodGraph MethodLet's try to solve the problem now.
Let :
Amount of Bread Type 1 = A
Amount of Bread Type 2 = B
1 piece of bread type 1 requires flour as much as 150 grams and 1 piece of bread type 2 requires flour as much as 75 grams, while the total amount of flour is as much as 2250 grams, then:
[tex]150A + 75B = 2250[/tex]
[tex]2A + B = 30[/tex]
[tex]\boxed{B = 30 - 2A}[/tex] → Equation 1
1 piece of bread type 1 requires butter as much as 50 grams and 1 piece of bread type 2 requires butter as much as 75 grams, while the total amount of butter is as much as 1250 grams, then:
[tex]50A + 75B = 1250[/tex]
[tex]2A + 3B = 50[/tex]
[tex]2A + 3(30 - 2A) = 50[/tex] ← Equation 1
[tex]2A + 90 - 6A = 50[/tex]
[tex]2A - 6A = 50 - 90[/tex]
[tex]-4A = -40[/tex]
[tex]A = -40 \div -4[/tex]
[tex]\large {\boxed{A = 10}}[/tex]
[tex]B = 30 - 2A[/tex]

A pearl is formed in one of every 10,000 oysters what percent of oysters make pearls
A student solved a system of equations by elimination. The answer is not correct. Describe the error made in the part of the solution shown.
The error made in the part of the solution is when equation (2) is multiplied by -4 it is not multiplied both side .
What is elimination method?The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the question
5x + 4y= 2 ------------------- (1)
3x + 3y = -3 ------------------- (2)
Now,
solving both equation by elimination method
Multiplying equation (1) by 3 and by 2 to equation (-4)
So, y can be eliminated
3(5x + 4y)=2 * 3
15x + 12y = 6 -------------- (3)
-4(3x + 3y) = -3*-4
-12x - 12y = 12 -----------------(4)
Now,
Adding both eq(3) and (4)
3x = 18
x = 6
Putting value of x in eq(1)
5*6 + 4y = 2
30 + 4y = 2
4y = 2 - 30
4y = - 28
y = -6
Hence, the error made in the part of the solution is when equation (2) is multiplied by -4 it is not multiplied both side .

why is a stem and leaf plot called a stem and leaf plot?
A stem-and-leaf plot gets its name from the way the data is structured. The 'stem' represents the highest place value digits of the numbers in the dataset, and the 'leaf' represents the lower place value digits. These plots keep the actual numerical data intact, providing more detail than other data representations like bar graphs or histograms.
Explanation:The term stem-and-leaf plot, also known as a stemplot, originates from the way data is structured in this type of graphical representation. The 'stem' in a stem-and-leaf plot stands for the highest place value digits of the numbers in the dataset, similar to the stem of a plant that holds up the leaves. The 'leaf' stands for the lower place value digits, similar to the leaves that extend from the stem. For example, in a dataset [23, 24, 33, 35], 2 and 3 would be stems, and the various units (3, 4 for 2 and 3, 5 for 3) would be leaves.
One of the main purposes of a stem-and-leaf plot is that it keeps the actual numerical data intact, as opposed to other graphical representations like bar graphs or histograms which group data into classes, thus providing a more detailed view of the data distribution.

If csc 0=8÷7 which equation represents cot 0
Answer: [tex]Cot\theta =\frac{\sqrt{15} }{7}[/tex]
Step-by-step explanation:
Since, given [tex]cosec\theta=\frac{8 }{7}[/tex]
And we know that [tex]Cot\theta=\sqrt{cosec^2\theta-1}[/tex]
Therefore, [tex]Cot\theta=\sqrt{cosec^2\theta-1} = \sqrt{(8/7)^2-1}= \sqrt{64/49-1}[/tex]
⇒[tex]Cot\theta=\sqrt{64-49/49}=\sqrt{15/49}=\sqrt{15}/7[/tex]
Thus, [tex]Cot\theta =\frac{\sqrt{15} }{7}[/tex]
Answer:
CotA=√15/7
Step-by-step explanation:
cosecA=8/7=hypotenuse/perpendicular
We have to find cotA
We do this by right angled triangle
We use pythagoras theorem to find the base
Base²+Perpendicular²=hypotenuse²
Base²+7²=8²
Base²=15
Base=√15
cotA=Base/Perpendicular
= √15/7
A scientist measures the angle x and the distance y between the Earth and the moon. Using complete sentences, explain how the scientist can use only these two measurements to calculate the distance between the Earth and the Sun.
tan =opposite/adjacent
In this case: tan =X , opposite=Y and adjacent= D
tan(x)=Y(opposite) /D(adjacent)
All terms in the equation are known except for 'D the distance'.
So the distance between the earth and the sun indicate by the symbol 'D' is equal to: y/tan(x)
if trapezoid jklm is translated according to the rule (x,y) ,(x+8,y-3) what are the coordinates of point L
With the given translation rule, to find new coordinates of a point L in trapezoid JKLM, apply it to the original coordinates by moving right by 8 units and down by 3 units. If original coordinates of L were (2,5), new coordinates will be (10,2).
Explanation:In geometry, a translation is a type of transformation that slides a figure along a straight line. In this case, the translation rule given is (x, y) -> (x+8, y-3). This means that every point in the trapezoid is being moved 8 units to the right (increase in x-coordinate) and 3 units down (decrease in y-coordinate).
Per your question, to find the new coordinates of point L after the translation, you simply need to apply this rule to the original coordinates of point L. If for example, the original coordinates of point L were (2, 5), its new coordinates after the translation would be calculated as follows: (2+8, 5-3) = (10, 2).
This is how you find the new coordinates of a point after a translation in geometry.

A parts number identifies one part of the smaller parts that make up the car. A serial number is unique to each car produced and identifies it.
Which relation is a function?
(parts number, serial number)
(model number, parts number)
(serial number, model number)
(serial number, part number)
Answer:
Hi!
The corrects answers are:
•(serial number, model number)

How to divide fractions
Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction. Let's try an example.
[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{5}{9}[/tex] can be rewritten as [tex]\frac{1}{2}[/tex] × [tex]\frac{9}{5}[/tex].
Now, we are simply multiplying fractions.
Multiply across the numerators and the denominators
[tex]\frac{1}{2}[/tex] × [tex]\frac{9}{5}[/tex] = [tex]\frac{9}{10}[/tex]
Therefore, [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{5}{9}[/tex] = [tex]\frac{9}{10}[/tex]

The value of a treadmill bought new for $1000 decreases 5% each year. Use a graph to predict the value of the treadmill in 5 years.
A) ≈ $773.78
B) ≈ $857.38
C) ≈ $902.50
D) ≈ $814.50
The predicted value of the treadmill after 5 years, with an annual depreciation rate of 5%, is approximately $773.78. This calculation uses the exponential decay formula and corresponds to option A).
To predict the value of a treadmill in 5 years that was bought new for $1000 and decreases 5% each year, we can use the formula for exponential decay:
V = [tex]P(1 - r)^t[/tex]
Where:
V is the future value of the treadmill,
P is the original value ($1000),
r is the rate of decay (5% or 0.05), and
t is the time in years (5 years).
By substituting the values we have:
V = $1000(1 - 0.05)⁵
V = $1000(0.95)⁵
V = $1000(0.77378) = $773.78
Therefore, the predicted value of the treadmill after 5 years is approximately $773.78, which corresponds to option A).
