Find the Area ( PLEASE LEAVE EXPLANATION)
Answer:
28 ft²
Step-by-step explanation:
Hello There!
To solve for the area of an irregular shape we want to split the irregular shape into regular shapes
For this irregular shape we would split it into a square with a side length of 2ft and a rectangle with a length of 6ft and a width of 4ft ( width was found subtracting total height of irregular figure (6ft) from height of square (2ft) 6ft - 2ft = 4ft so the width would be 4ft)
now we can easily solve for the area of each individual shape
area of square -
the area of a square can simply be found by raising the side length to the power of 2
so
\(a =2^2\\2^2=4\\a=4ft^2\)
so we can conclude that the area of the square is 4ft^2
Now we want to find the area of the rectangle
the area of a rectangle is simply equal to the width times the length
so
\(a=6*4\\6*4=24\\\\a=24ft^2\)
so we can conclude that the area of the rectangle is 24ft^2
Finally we add the two areas together
24 + 4 = 28
thus meaning the area of the irregular figure is 28 ft²
musicians need to be able to discern frequencies which are quite near each other. assume that the average musician can differentiate between frequencies that vary by only 0.6%. this corresponds to about 1/10 of the frequency difference between neighboring notes in the middle of the piano keyboard.
Musicians need to have the ability to discern frequencies that are very close to each other in order to accurately distinguish between different notes and tones in music.
In this context, it is assumed that the average musician can differentiate between frequencies that vary by only 0.6%. This means that they can perceive a difference of 0.6% in frequency between two sounds. To put this into perspective, let's consider the piano keyboard. The frequency difference between neighboring notes in the middle of the piano keyboard is divided into 12 equal parts, corresponding to the 12 semitones in an octave. Therefore, if we divide the frequency difference between neighboring notes by 12, we get the frequency difference between each semitone. Given that musicians can discern frequencies that vary by 0.6%, which is approximately 1/10 of the frequency difference between neighboring notes, we can conclude that they have a highly developed sense of pitch and can detect even the smallest variations in frequency.
In conclusion, musicians possess the ability to discern frequencies that are very close to each other, allowing them to accurately differentiate between different notes and tones in music.

Which equation represents the line that is perpendicular to the line 5x 2y =- 6?
The equation represents the line that is perpendicular to the line 5x - 2y =- 6 is y + 4 = -(2/5)(x - 5).
What is the slope-intercept form?
The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
Here, we have
The lines of the equations
Ax + By = C1
and Bx - Ay = C2 are perpendicular. Therefore, a line perpendicular to 5x - 2y = -6 must take the standard form 2x + 5y = C.
Substituting x = 5, y = -4, we get
C = 2(5) + 5(-4) = 10 - 20 = -10.
Thus, 2x + 5y = -10 is the correct choice.
This can be rewritten in slope-intercept form:
2x + 5y = -10
2x + 5y - 2x = -10 - 2x
5y = -2x - 10
5y / 5 = (-2x - 10) /5
y = -(2/5) x - 2
Its point-slope form is
y - y1 = m(x - x1)
y + 4 = -(2/5)(x - 5)
Hence, the equation represents the line that is perpendicular to the line 5x - 2y =- 6 is y + 4 = -(2/5)(x - 5).

In a species of wildflower, some plants produce pink flowers while other plants produce white flowers. In a cross between two pink wildflowers, 77% of the offspring produced pink flowers and 23% produced white flowers. If two wildflower plants with white flowers were crossed, what percentage of their offspring would most likely produce pink flowers?
The expected percentage of their offspring that would produce pink flowers would be 0%. This is because both the parents that are involved in the cross produce only white flowers and therefore the offspring produced as a result of the cross are expected to only produce white flowers.
However, if the offspring from the cross between the two white flower producing wildflowers were to be crossed with another wildflower population that has pink flowers, there is a chance that some of the offspring from that cross would produce pink flowers. In the given scenario, the cross is being made between two white flower producing wildflowers. Since both the parents involved in the cross produce only white flowers, there is no chance of their offspring producing pink flowers.
The color of the flowers in the offspring is determined by the genetic makeup of the parents that are involved in the cross.In the case of the given wildflowers, the fact that 77% of the offspring produced by a cross between two pink wildflowers produced pink flowers while 23% produced white flowers indicates that the gene for pink flowers is dominant over the gene for white flowers. This is because the gene for pink flowers was passed down to more than three-quarters of the offspring in the cross between the two pink wildflowers. The gene for white flowers, on the other hand, was passed down to only a quarter of the offspring.Hence, if the offspring from the cross between the two white flower producing wildflowers were to be crossed with another wildflower population that has pink flowers, there is a chance that some of the offspring from that cross would produce pink flowers.

Which graph shows the solution to the system of linear inequalities? 2x -3y ≤ 12 y < -3
Answer: The third graph (the one on the right side)
Step-by-step explanation:
The inequalities are:
2x -3y ≤ 12
y < -3
First, for the second inequality, we can see that y must be strictly less than -3, so we should see a dotted line at y = 3, and a shaded section under that line.
From this, we can discard the second graph (the middle one).
The first inequality can be rewritten as:
2x - 3y ≤ 12
-3y ≤ 12 - 2x
Now we divide by -3 on both sides, as we are dividing by a negative number, the direction of the ≤ sign changes:
y ≥ (12/-3) + (-2/-3)x = -4 + (2/3)*x
This means that the shaded section must be above the line:
y = -4 + (2/3)*x
Then the correct option is the third graph (rightmost graph).

write the (exact) area under a curve as a limit of riemann sums and (for certain curves) evaluate that limit.
The area under a curve can be written as a limit of Riemann sums. Riemann sums are used to estimate the area of a curve. To find the area of a curve, it is divided into small rectangles whose combined areas approximate the area of the curve. The limit of the sum of the areas of these rectangles is the exact area of the curve.
The Riemann sum is given by the formula:
Riemann sum = (b-a)/n ∑ f(xi)
The limit of the Riemann sum is given by the formula:
lim [ (b-a)/n ∑ f(xi) ]
The limit of the Riemann sum gives the precise area under a curve. Unfortunately, the limit can only be determined for specific curves. For example, if the curve is described by a simple function like y = x2 or y = sin(x), the limit may be calculated using calculus. Riemann sums may be used to estimate the area of a curve by splitting it into a finite number of rectangles of equal width.
The area of each rectangle is then determined by multiplying the height of the curve by the width of the rectangle. Summing the areas of each rectangle yields the overall area. The precise area under a curve is the limit of the Riemann sum. Nonetheless, the limit can be exceeded. The limit of the Riemann sum is the exact area under a curve. However, the limit can only be evaluated for certain curves using calculus.

if you construct a line perpendicular to line a given by y=22 through s(1,5) not on the line y=22, find the distance from s to line a
Therefore, The distance from S to line A is 17 units.
To find the distance from point S to line A, we first need to find the equation of the line perpendicular to A through S. Since A is a horizontal line, the perpendicular line will be vertical. Therefore, the equation of the perpendicular line passing through S(1,5) is x=1.
Next, we find the point where this line intersects with A. This point will have the same y-coordinate as A, which is 22, but the x-coordinate will be 1. Therefore, the point of intersection is (1,22).
Finally, we use the distance formula to find the distance from S to the point of intersection on A:
distance = √[(22-5)^2 + (1-1)^2] = √(17^2) = 17.
So the distance from S to line A is 17 units.

The preparer wrapped each of the nine rolls and once warpped, the rolls were indistinguishable from one another. She then randomty put three rolls in a bag for each of the guests. If the probability that each guset got one roll of each type is m/n where m and n are relatively prime integers, find the value of (m+n)
The total number of ways to distribute the rolls is 84 * 20 * 1 = 1680, The value of (m + n) is 1 + 1680 = 1681.
To solve this problem, we can use the concept of combinations. Let's consider the three types of rolls as N (nut), C (cheese), and F (fruit). We need to find the probability that each guest receives one roll of each type.
There are a total of 9 rolls, and each guest receives 3 rolls. The total number of ways to distribute the rolls among the guests is given by 9C3 * 6C3 * 3C3 since each guest gets one roll of each type.
Calculating the combinations:
9C3 = 84 (number of ways to choose 3 rolls out of 9)
6C3 = 20 (number of ways to choose 3 rolls out of the remaining 6 after the first guest's selection)
3C3 = 1 (only one way to choose 3 rolls out of the remaining 3 after the first two guests' selections)
Therefore, the total number of ways to distribute the rolls is 84 * 20 * 1 = 1680.
To find the probability, we divide the favorable outcomes (cases where each guest gets one roll of each type) by the total possible outcomes:
Probability = Favorable outcomes / Total outcomes = 1 / 1680.
The value of m is 1, and the value of n is 1680.
Thus, the value of (m + n) is 1 + 1680 = 1681.

(54 + 81 + 27) = 27 × (2+3+1)
(16 + 28 + 48) = 4 × (4+7+12)
Thus, the above equations represent each expression as a multiple of a sum of whole numbers with no common factor.
