The rate of change picking the apples is 8 bushels of apples per hour.
What is rate of change?Rate of change is used to mathematically describe the percentage change in value over a defined period of time, the formula for rate of change is: R = (D2 - D1)/T. where: R = rate of change.
Given that, you and your best friend are picking apples at a local orchard. there were already 12 bushels of apples on the tractor when you began at 8:00 am and you picked apples until noon, we are asked to find, what was your rate of change if there were 44 bushels filling the tractor when you stopped,
So, the rate change = total apples picked in 8 am to noon / number of hours.
Therefore, the total apples picked in 8 am to noon =
Since, it was 44 bushels at the end and when they started there were already 12 bushels, so the number of bushels of apples filled between given hours = 44 - 12 = 32 bushels.
The number of hours in picking 32 bushels of apples = 12 noon - 8 am
= 4 hours
Therefore,
The rate of change = 32 / 4
= 8
Hence, the rate of change picking the apples is 8 bushels of apples per hour.

How do you write 940% as a fraction or mixed number
Answer:
Fraction: 47/15
Mixed number: 3 2/15
Step-by-step explanation:
Hope it helps! =D
A percentage is a ratio, or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.
If we know that percentages are parts of 100, we can simply set the denominator as 100, and keep the numerator the same.
940% = [tex]\frac{940}{100}[/tex]Converting this into a mixed number will look like this:
[tex]\frac{940}{100} = 9 \frac{40}{100}[/tex] or [tex]9 \frac{4}{10}[/tex]Therefore, the percentage 940% written as a mixed number is [tex]9\frac{4}{10}[/tex].

What is Reflection?Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.
The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

The value of the trigonometry identity is tan(2x) = 4/7[√2]
How to determine the trigonometry identityFrom the question, we have the following parameters that can be used in our computation:
cos(x) = 2√5/5 and 3π/2 < x < 2π
Start by calculating the sine function sin(x) using
sin(x) = √[1 - cos²(x)]
So, we have
sin(x) = √[1 - (2√5/5)²]
This gives
sin(x) = 1/10[√10]
The tangent is then calculated as
tan(2x) = (2sin(x)cos(x))/(cos²(x) - sin²(x))
This gives
tan(2x) = (2 * 1/10[√10] * (2√5/5))/(((2√5/5))² - (1/10[√10])²)
Evaluate
tan(2x) = 4/7[√2]

In a group of 40 pupils, 15 play the flute only. 7 play the piano only. 5 play both instruments. A student is chosen at random. What is the probability the student plays neither instrument?
Answer:
13/40
Step-by-step explanation:
Total No of pupils = 40
No of pupils who play the flute = 15
No of pupils who play the Piano = 7
No of pupils who play both = 5
Total No of pupils who can play the atleast one instrument = 15+5+7= 27
No one pupils who play neither instrument = 40 - 27 = 13
Probability of a pupil being chosen at random who plays neither instrument = No of Pupils who play neither instrument/ Total No of pupils = 13/40
Therefore the answer will be 13/40
over an interval of 3.0 s the average rate of change of the concentration of a was measured to be -0.0680 m/s. what is the final concentration of c at the end of this same interval if its concentration was initially 2.700 m?
The equation for the rate of change of concentration is Δc/Δt, and this is equal to the rate of change of concentration over a given interval, -0.0680 m/s.
To calculate the final concentration, we must use the equation Δc = rate × time, where Δc is the change in concentration, and rate and time are the rate of change of concentration and the interval, respectively. Plugging in our values, Δc = -0.0680 m/s × 3.0 s = -0.204 m. This means that the final concentration of c is 2.700 m - 0.204 m, which is equal to 2.496 m.
To summarize, the rate of change of concentration equation is Δc/Δt = rate of change, and the equation to calculate the final concentration is Δc = rate × time. Plugging in the rate of change and interval, we get Δc = -0.0680 m/s × 3.0 s = -0.204 m, which gives us the final concentration of c at the end of the same interval as 2.496 m.

a) The new production rate is 1008 items per week.
b) The new unit cost is $63.
What is the rate?A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.
a) The new production rate can be calculated by increasing the old production rate of 900 items per week by 12%.
New production rate = 900 items/week + 12% of 900 items/week
New production rate = 900 items/week + (12/100) x 900 items/week
New production rate = 900 items/week + 108 items/week
New production rate = 1008 items/week
So, the new production rate is 1008 items per week.
b) The new unit cost can be calculated by reducing the old unit cost of $75 by 16%.
New unit cost = $75 - 16% of $75
New unit cost = $75 - (16/100) x $75
New unit cost = $75 - $12

The angle measures of each vertex of the garden are 53.13 degrees.
In Parallelogram ABCD, diagonals AC and BD intersect at point A = √7.
What is angle?Angle is a geometric figure that can be described as the amount of rotation between two straight line or planes and angle is measured in degree with a full circle being 360°.
1. To determine the angle measures of each vertex of the garden, we must first calculate the angles formed by each side. For example, the angle formed by sides AB and BC can be found by using the inverse tangent function. The equation would be
arctan(BC/AB) = arctan (4/3) = 53.13 degrees.
The angles for the other sides can be calculated in the same way. We can then use the sum of angles theorem to calculate the angles at each vertex. Since the garden is an irregular shape, the angles at each vertex will be different.
2. In Parallelogram ABCD, diagonals AC and BD intersect at point A. To calculate , we can use the distance formula.
The equation would be = √((x2 – x1)2 + (y2 – y1)2).
For the coordinates given, we would have

Yosemite Falls, the highest waterfall in the United States, is actually made up of three smaller falls. The Lower Yosemite Falls is 355 feet shorter than the Middle Cascades Falls. The Upper Yosemite Falls is 80 feet more than twice the Middle Cascades Falls. If the entire set of waterfalls is 2425 feet long, how tall is Lower Yosemite Falls?
As per unitary method Lower Yosemite Falls is 292.5 feet tall.
The unitary method is a mathematical problem-solving technique that involves using known information to find unknown information.
Let x be the height of the Middle Cascades Falls. The height of the Lower Yosemite Falls is 355 feet shorter than x, so the equation is:
Lower Yosemite Falls = x - 355
The height of the Upper Yosemite Falls is 80 feet more than twice the height of the Middle Cascades Falls, so the equation is:
Upper Yosemite Falls = 2x + 80
The total height of all three falls is 2425 feet, so we can add the heights of each fall to find the equation:
Lower Yosemite Falls + Middle Cascades Falls + Upper Yosemite Falls = 2425
Substituting in our previous equations:
x - 355 + x + 2x + 80 = 2425
Simplifying:
4x = 2425 + 355 - 80
4x = 2590
Dividing both sides by 4:
x = 647.5
So, the height of the Middle Cascades Falls is 647.5 feet. To find the height of the Lower Yosemite Falls, we substitute x back into the first equation:
Lower Yosemite Falls = x - 355
Lower Yosemite Falls = 647.5 - 355
Lower Yosemite Falls = 292.5 feet

meters. The parallelogram has an area of 306 square meters. What is the value of x?
9
17
18
34
Answer:
The area of a parallelogram is given by the formula A = base x height. In this case, the base has a length of x meters, and the height is x - 1 meters. So we can write:
A = x(x - 1)
We are told that the area is 306 square meters, so we can set up an equation:
x(x - 1) = 306
Expanding the left side gives:
x^2 - x = 306
Bringing all the terms to one side gives a quadratic equation:
x^2 - x - 306 = 0
We can solve for x using the quadratic formula:
x = (-b ± sqrt(b^2 - 4ac)) / 2a
Here, a = 1, b = -1, and c = -306, so:
x = (1 ± sqrt(1 - 4(1)(-306))) / 2(1)
x = (1 ± sqrt(1 + 1224)) / 2
x = (1 ± sqrt(1225)) / 2
x = (1 ± 35) / 2
So x is either (1 + 35) / 2 = 18 or (1 - 35) / 2 = -17/2. Since x represents a length, it cannot be negative, so the value of x is 18 meters.
Therefore, the answer is x = 18.
