C. [tex]\frac{1}{3}y-\frac{7}{5}x+\frac{2}{3}-\frac{2}{3}y-\frac{4}{9}[/tex] matches with [tex]-\frac{2}{3} y -\frac{3}{5} x+\frac{2}{9} -\frac{4}{5} x+\frac{1}{3} y[/tex]
Step-by-step explanation:
[tex]-\frac{2}{3} y -\frac{3}{5} x+\frac{2}{9} -\frac{4}{5} x+\frac{1}{3} y[/tex]
[tex]-\frac{3}{5}x+\frac{2}{9}-\frac{4}{5}x=-\frac{7}{5}x+\frac{2}{3}-\frac{4}{9}[/tex]
[tex]-\frac{3}{5}x+\frac{2}{9}-\frac{4}{5}x=\frac{2}{9}-\frac{7}{5}x[/tex]
[tex]-\frac{3}{5}x-\frac{4}{5}x=-\frac{7}{5}x[/tex]
[tex]-\frac{3}{5}x-\frac{4}{5}x+\frac{7}{5}x=-\frac{7}{5}x+\frac{7}{5}x[/tex]

A teacher wants to find the average (mean) grade on a math test. The gradebook program can provide data about the class as a stem-and-leaf plot or as a box-and-whisker plot. Which plot should she use? Why?
Answer:
Box-and-whisker plot
Step-by-step explanation:
Box-and-whisker plot is a graph commonly used to not only find the mean but find the minimum, maximum, third and first quartile. In order to calculate the mean of a set of data, you have to rearrange the data and the middle number separating one half of the set, from the other half of the set is the mean. Box-and-whisker plot can accurately show the average grade on this math test.

The junior class sold boxes of pecans at $6 each and boxes of peanuts at $5 each. They sold a total of 82 boxes for $440. How many boxes of pecans and peanuts did they sell?
I NEED THE EQUATIONS...I can get the number of pecans and peanuts..I just need the equation to find them..please help me
This is Algebra
Answer:
Following are the required equations
[tex]x +y=84[/tex]
[tex]6x +5y=440[/tex]
Step-by-step explanation:
Let x boxes of pecans and y boxes of peanuts sold.
Total no of boxes sold = 84
[tex]\implies x +y=84[/tex]
Cost of one box of pecan =$6
So, cost of x boxes of pecans =$6x
Cost of one box of peanuts = $5
So, cost of y boxes of peanuts =$5y
Total sales = $440
[tex]\implies 6x +5y=440[/tex]

How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For the given case, it is specified that:
Total number of employed writers and authors: 153,000Some college experience but no degree : 12.4%Bachelor's degree or higher : 84.1%Let we have:
writers and authors with bachelor’s degree = N + writers and authors with some college experience and no degree
(so the number of writers and authors with bachelor’s degree is N more than writers and authors with some college experience but no degree)
Number of writers and authors with bachelor's degree = 12.4% of 153000
which is [tex]\dfrac{153000}{100} \times 12.4 = 18972[/tex]
Number of writers and authors with some college experience but no degree = 84.1% of 153,000 which is [tex]\dfrac{153000}{100} \times 84.1 = 128673[/tex]
Thus,
128,673 = N + 18972
or
N = 128,673 - 18972= 109,701
Thus,
Number of Writers and authors with bachelor's degree more than those with only some college experience and no degree is Option b: 109701

Step-by-step explanation:
A recursive formula lets us calculate a term in the sequence by multiplying the previous term by the common ratio r
for the sequence
- 3, 9 , - 27 , 81....
the common ratio r is
r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 3
Then the recursive formula is
f(n) = - 3 f(n - 1) if n > 1
f(1) = - 3
option D
Answer:
D)
Step-by-step explanation:
A recursive formula always has two parts: the value of an initial term (or terms), and an equation defining [tex]a_n[/tex] in terms of preceding terms.
From inspection, the initial term is -3
[tex]\implies a_1=-3[/tex]
[tex]\implies f(1)=-3[/tex]
From inspection, we can see that each term is the preceding term multiplied by -3. Therefore, the sequence can be defined as:
[tex]a_n=-3(n-1)[/tex]
[tex]\implies f(n)=-3f(n-1)[/tex]
So the recursive formula for the sequence is D)
[tex]f(n)=\left \{ {{f(1)=-3} \atop {f(n)=-3f(n-1)}} \right.[/tex]

b/
36*3/4=27s (closest)
36*1/4=9s (farthest)
c/
20ft
Answer:
a) 10°
b) closest: 27 seconds
farthest: 9 seconds
c) 20 ft
Step-by-step explanation:
a) Angles around a point add up to 360°, therefore 1 rotation = 360°
If it makes one rotation in 36 seconds, then there are 10° per second as 360/36 = 10
b) closest to wall: this will be a 3/4 rotation:
3/4 of 36 seconds = 0.75 x 36 = 27 seconds
farthest from wall: 1/4 rotation:
1/4 of 36 = 0.25 x 36 = 9 seconds
c) 18 seconds is half of 36 seconds. Therefore, you will have made a 1/2 rotation. So you will be on the same horizontal plane as the start position, but on the opposite side of the circle (see attached diagram).
Therefore, you will be 20ft away from the wall (shown in blue).

There is a direct proportionality between volume and temperature (in Kelvin) of a gas. The volume of a sample of a gas at 277 Kelvin is 2.1883 L.
Which of the following shows a direct variation equation relating the volume V and the temperature T?
Options:
1. V= 0.0079T
2. V= 126.6T
3. T=606.2V
4. T= 0.0079V
Answer:
2. V= 126.6T4. T= 0.0079VExplanation:
V = kT
[ where k is constant ]
277 = k(2.1883)
k = [tex]\frac{277}{2.1883}[/tex]
k = 126.6
Therefore: V = 126.6TVk = T
277k = 2.1883
k = 2.1883/277
k = [tex]7.9 * 10^{-3}[/tex]
V * [tex]7.9 * 10^{-3}[/tex] = T
T = 0.0079V
Therefore T = 0.0079V
A circular swimming pool has a radius of 28 ft. There is a path all the way around the pool that is 4 ft wide. A fence is going to be built around the outside edge of the pool path. A circle has a radius of 28 feet. A larger circle goes around the smaller circle that is 4 feet wide. About how many feet of fencing are needed to go around the pool path? Use 3. 14 for Pi. 88 ft 100 ft 176 ft 201 ft.
There is 201 feet of fencing are needed to go around the pool path.
Given
A circular swimming pool has a radius of 28 ft.
There is a path all the way around the pool that is 4 ft wide.
A fence is going to be built around the outside edge of the pool path.
A circle has a radius of 28 feet.
A larger circle goes around the smaller circle that is 4 feet wide.
Circumference;For the length of the fence, we need to find the circumference of the outside of the pool path.
The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= 28 + 4 = 32 feet
The radius is then equal to 32 feet.
The circumference of the outer edge of the pool path would be equal to the perimeter;
[tex]\rm Perimeter = 2\pi r[/tex]
Where r is the radius.
Substitute all the values in the formula;
[tex]\rm Perimeter = 2\pi r\\\\\rm Perimeter = 2\times 3.14 \times 32\\\\Perimeter = 201[/tex]
Hence, there is 201 feet of fencing are needed to go around the pool path.
