Identify the percent of change as an increase or a decrease. 4/5 to 3/5 Increase Decrease Find the percent of change. Round to the nearest tenth of a percent if necessary.
The required percent of change from 4/5 to 3/5 is a decrease of 25%.
What is the percentage?The percentage is the ratio of the composition of value to the overall composition of value multiplied by 100.
Here,
The fraction 4/5 is greater than the fraction 3/5, so the change from 4/5 to 3/5 represents a decrease.
To find the percent of change, we first need to find the amount of change. We can do this by subtracting the original value (4/5) from the new value (3/5),
3/5 - 4/5 = -1/5
The amount of change is -1/5. To express this as a percent, we can use the formula.,
Percent change = (amount of change / original value) * 100%
Substituting the values we have,
Percent change = (-1/5 / 4/5) * 100%
Percent change = -0.25 * 100%
Percent change = -25%
Therefore, the percent of change from 4/5 to 3/5 is a decrease of 25%.

Each of students reported the number of movies they saw in the past year. Here is what they reported. 17,19,10,4,16,20
Answer:
14.3
Step-by-step explanation:
What you would do is add all 6 numbers together. After finding the sum, divide by 6. The 6 represents the amount of numbers in the data set. So you would find 86/6 and get 14.3333. That would be rounded to 14.3. Hope this helped!

Adam bought a baseball bat and a baseball. He paid $ 1.10 for two of them. The baseball bat cost $ 1 more than a ball. What are the prices of these items?
Answer:
0.05
Step-by-step explanation:
Lets consider that cost of bat is 'x' and cost of baseball is 'y'.
Therefore, according to the question
x + y = $1.10
And the cost of bat is one dollar more than that of baseball, therefore -
x - y = $1.00
Now let us add these two equations, which will cancel out 'y' i.e, cost of baseball
=> 2x = $2.10
=> x = $1.05
Thus the cost of bat is $1.05
Now substitute this value of x in any equation...lets consider in first equation
=> 1.05 + y= 1.10
=> y = $0.05
Therefore the cost of baseball is $0.05.
I hope this helps! (If it does, may I please get brainliest?)

The Period of the Function is 8π.
What is period of the function?The period of the function is the interval between repetitions of any function. A trigonometric function's period is the length of one whole cycle.
The interval of x-values that corresponds to the size of one cycle is the function's period.
Added significance The distance between two comparable locations, such as the distance between two peaks of the function, is known as the function's period.
As shown on the graph, the function has peak value and repeated every

Mary’s annual salary is $38,500 plus 22% in employee benefits. Her yearly job expenses are: uniforms, $500; transportation and parking, $5,350; and tools and certifications, $1,200. What are her net job benefits?
Answer: $39,920
Step-by-step explanation:
Her net job benefits would be the benefits and salary she receives less the expenses she incurs in relation to the job:
= Salary + Benefits - Uniforms - Transport - Tools
= 38,500 + (22% * 38,500) - 500 - 5,350 - 1,200
= 46,970 - 7,050
= $39,920
Find the amount that results from the given investment.
$100 invested at 11% compounded quarterly after a period of 3 years
Answer:
$138.27.
Step-by-step explanation:
Given that it is required to obtain the amount of money that arises from $ 100 invested at 11% compounded quarterly after a period of 3 years, to determine said amount the following calculation must be performed:
X = 100 x (1 + 0.11 / 3) ^ 3x3
X = 100 x (1 + 0.03666) ^ 9
X = 100 x 1.03666 ^ 9
X = 100 x 1.3827
X = 138.27
Thus, the amount that will arise from said investment is $ 138.27.

10 POINTS (ignore the bottom and top questions pls lol)
Can you guys find the slope and y-intercept
Answer:
Step-by-step explanation:
Plot any tow points on the line and find the slope
(-1 , 3) ; ( -2 , 1)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{1-3}{-2-[-1]}\\\\= \frac{-2}{-2+1}\\\\=\frac{-2}{-1}\\\\=2[/tex]
m = 2 ; (-1 , 3)
y - y1 = m(x - x1)
y - 3 = 2*(x - [-1])
y - 3 = 2*(x + 1)
y -3 = 2*x + 2*1
y -3 = 2x + 2
y = 2x + 2 + 3
y = 2x + 5
Slope = 2
y-intercept = 5

Answer:
10a. No
10b. No
10c. Yes
10d. Yes
Step-by-step explanation:
10a. This equation does not because 3/4 x 8 = 6 and not 9.
10b. This equation doesn’t because 3x8 does not equal 28.
10c. This equation does because 5 x 8 = 40 which means y = 8.
10d. This equation does because 8/2 = 4. Fractions are just division problems and 8 divided by 2 equals 4, meaning y = 8 was n this equation.
