The percentage of people who participated in the race finished in less than 56 minutes is 34%. This can also be written as the equivalent fraction 34/100
To find the percentage of people who finished the race in less than 56 minutes, we can use the following formula:
percentage = (part/whole) x 100%
where "part" is the number of people who finished in less than 56 minutes, and "whole" is the total number of people who participated in the race.
In this case, we know that 17 people finished in less than 56 minutes, and there were 50 people in total. So we can plug these values into the formula:
percentage = (17/50) x 100%
percentage = 34%
Therefore, 34% of the people who participated in the race finished in less than 56 minutes.
To write an equivalent fraction for this percentage, we can write:
34% = 34/100
This is an equivalent fraction because 34/100 can be simplified to 17/50

Correct tion for the circle with the following properties. Center (4,8), passes through (-10,-5)
The equation of a circle with center at (4, 8) and passing through (-10, -5) is [tex](x-4)^2 + (y-8)^2 = (6)^2.[/tex]
To find this equation, we need to use the distance formula: [tex]d = sqrt((x2-x1)^2 + (y2-y1)^2).[/tex]
We can substitute in the coordinates of the center of the circle and the point it passes through:
[tex]d = sqrt((-10-4)^2 + (-5-8)^2)[/tex]
[tex]d = sqrt( (6)^2 + (13)^2 )[/tex]
d = sqrt(36 + 169)
d = sqrt(205)
d = 14.2
Now, we have the radius of the circle. We can use this to form the equation of the circle:
[tex](x-4)^2 + (y-8)^2 = (14.2)^2[/tex]
[tex](x-4)^2 + (y-8)^2 = (6)^2[/tex]

Eight people are to be seated in a row of 8 chairs. In how many ways can these people be seated if two of them insist on sitting next to one another?
The final answer is 8*2=16 ways
Eight people are to be seated in a row of 8 chairs. In how many ways can these people be seated if two of them insist on sitting next to one another?
There are a couple of steps to solving this problem.
Step 1: Consider the two people who insist on sitting next to one another as one unit. This means that there are now 7 units to be seated in the 8 chairs.
Step 2: Calculate the number of ways that the 7 units can be seated in the 8 chairs. This is done using the formula n!/(n-r)!, where n is the number of chairs and r is the number of units. In this case, n=8 and r=7, so the formula is 8!/(8-7)!, or 8!/1!, which simplifies to 8.
Step 3: Calculate the number of ways that the two people who insist on sitting next to one another can be seated within their unit. There are 2! or 2 ways that they can be seated.
Step 4: Multiply the number of ways that the 7 units can be seated in the 8 chairs by the number of ways that the two people can be seated within their unit. This gives us the total number of ways that the 8 people can be seated if two of them insist on sitting next to one another.
So the final answer is 8*2=16 ways.

Do segments with lengths 11, 12, and 20 form a triangle? If so, classify the triangle as acute, right, or obtuse?
Answer:
Yes, the segments with lengths 11, 12, and 20 can form a triangle.
To check this, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, we can check that:
11 + 12 > 20
11 + 20 > 12
12 + 20 > 11
Since all three inequalities are satisfied, the segments can form a triangle.
To classify the triangle, we can use the law of cosines, which relates the lengths of the sides of a triangle to the cosine of one of its angles. Specifically, for a triangle with sides a, b, and c and angle A opposite side a, we have:
c^2 = a^2 + b^2 - 2ab cos(A)
Using this formula, we can find the cosine of each angle and determine if the triangle is acute, right, or obtuse based on the values obtained.
For the given triangle, we have:
a = 11, b = 12, c = 20
cos(A) = (b^2 + c^2 - a^2) / (2bc) = (12^2 + 20^2 - 11^2) / (2 * 12 * 20) ≈ 0.714
Since cos(A) is positive and less than 1, the angle A is acute. Similarly, we can find the cosines of the other angles:
cos(B) = (c^2 + a^2 - b^2) / (2ca) ≈ 0.943
cos(C) = (a^2 + b^2 - c^2) / (2ab) ≈ -0.519
Since cos(B) and cos(C) are both positive and less than 1, angles B and C are also acute.
Therefore, the given triangle is acute.

Work out the surface area of this solid
cylinder.
Give your answer rounded to 3 SF.
28mm
30mm
The diagram is not drawn to scale.
Answer: The surface area of a cylinder is given by the formula:
S = 2πr^2 + 2πrh
where r is the radius of the base, h is the height of the cylinder, and π is the mathematical constant pi.
In this case, the radius is 28 mm and the height is 30 mm.
Substituting these values into the formula, we get:
S = 2π(28)^2 + 2π(28)(30)
Simplifying the equation:
S = 2π(28)(28 + 30)
S = 2π(28)(58)
S = 32176π
Using a calculator, we can approximate the value of S to 3 significant figures:
S ≈ 101285.744 mm^2
Therefore, the surface area of the cylinder is approximately 101286 mm^2 (rounded to 3 significant figures).

What is isosceles trapezoid?An isosceles trapezoid can be defined as a trapezoid whose non-parallel sides and base angles have the same measure. That is, if the two opposite sides (bases) of a trapezoid are parallel and the two non-parallel sides are of equal length, it is an isosceles trapezoid.
Given,
Isosceles trapezoid QRST
m∠S = 82°
Base angles are equal in Isosceles trapezoid
m∠R = m∠S
m∠R = 82°
and
m∠Q = m∠T
Sum of all interior angles of a quadrilateral is 360°
m∠Q + m∠T + m∠R + m∠S = 360°
m∠Q + m∠Q + 82° + 82° = 360°
2 m∠Q = 360° - 164°
2 m∠Q = 196°
m∠Q = 98°
m∠T = 98°

The coordinates of B' after the translation represented by (x - 4, y - 3) is (1, -2). See other solutions below
The coordinates of B' after the translationB is located at the point (5, 1) in the figure.
If we translate the point by (x - 4, y - 3), the new location of B, denoted by B', can be found by subtracting 4 from the x-coordinate and 3 from the y-coordinate.
Therefore, B' is located at (1, -2).
The isometry transformationThe given information provides us with a set of matching points, which are:
Preimage = (2, 1)
Image = (-1, 2)
These points can be represented by the equation:
(x, y) = (-y, x)
This equation indicates that the points have undergone a (d) clockwise rotation of 270 degrees.
The statements of the dilationHere, the smaller shape is created by scaling down a larger shape, the transformation is a dilation that results in a reduction.
The scale factor for this transformation could be either 1/2 or 1/4.
The glide transformatonGiven the points P = (3, -2) and S = (4, -5), we apply two transformations.
The first transformation (x - 2, y) is defined as shifting the x-coordinate of each point left by 2 units, while keeping the y-coordinate the same.
This results in new points P' = (1, -2) and S' = (2, -5).
The second transformation involves reflecting the new points across the x-axis, which changes the sign of their y-coordinates.
The resulting points are P'' = (1, 2) and S'' = (2, 5).
The new ordered pair of point AIn this context, we are given the coordinates of point A as (-2, -5).
This implies that if we scale down the original coordinates by a factor of 1/2, we get the new coordinates of point A, which become (-1, -2.5).
Therefore, the coordinates of point A' are (-1, -2.5).

A retailer sells model solar systems for $72 that were acquired at a cost of $24. What is the mark-up percentage?
Therefore, the mark-up percentage for the model solar system is 200%. This means that the selling price is twice the cost price.
I have to figure out a percentage.We must divide the value by the entire value to find the percentage, then increase the resulting number by 100.
The mark-up percentage is the percentage by which the selling price exceeds the cost price.
In this case, the cost price of the model solar system is $24 and the selling price is $72. The mark-up amount is the difference between the selling price and the cost price, which is:
$72 - $24 = $48
To find the mark-up percentage, we divide the mark-up amount by the cost price and multiply by 100:
Mark-up percentage = (Mark-up amount / Cost price) x 100%
Mark-up percentage = ($48 / $24) x 100%
Mark-up percentage = 200%
Therefore, the mark-up percentage for the model solar system is 200%. This means that the selling price is twice the cost price.

Find the determinant. \[ \left|\begin{array}{ccc} d+b & d & d \\ d & d+b & d \\ d & d & d+b \end{array}\right| \]
The determinant of a 3x3 matrix can be found using the following formula:
\[ \left|\begin{array}{ccc} a & b & c \\ d & e & f \\ g & h & i \end{array}\right| = a(ei - fh) - b(di - fg) + c(dh - eg) \]
In this case, we can substitute the values from the given matrix into the formula:
\[ \left|\begin{array}{ccc} d+b & d & d \\ d & d+b & d \\ d & d & d+b \end{array}\right| = (d+b)((d+b)(d+b) - d^2) - d(d(d+b) - d^2) + d(d^2 - d(d+b)) \]
Simplifying the expression gives:
\[ = (d+b)(d^2 + 2bd + b^2 - d^2) - d(d^2 + bd - d^2) + d(d^2 - d^2 - bd) \]
\[ = (d+b)(2bd + b^2) - d(bd) + d(-bd) \]
\[ = 2bd^2 + 2b^2d + b^3 - bd^2 - bd^2 \]

The CEO of Super Electronics asked customers to fill out a survey to win a $100 gift certificate. The customers were asked to list the products they purchased that day. 88 bought laptop computers. 52 bought desktop computers. 64 bought printers. What is the probability that the winner of the gift certificate bought a printer from Super Electronics? A.
Answer:
To calculate the probability that the winner of the gift certificate bought a printer from Super Electronics, we need to use the total number of customers who participated in the survey as the denominator and the number of customers who bought printers as the numerator.
The total number of customers who participated in the survey is:
Total Customers = Number of Customers who bought Laptops + Number of Customers who bought Desktops + Number of Customers who bought Printers
Total Customers = 88 + 52 + 64
Total Customers = 204
The number of customers who bought printers is 64.
Therefore, the probability that the winner of the gift certificate bought a printer from Super Electronics is:
P(Bought a Printer) = Number of Customers who bought Printers / Total Customers
P(Bought a Printer) = 64 / 204
P(Bought a Printer) = 0.3137 (rounded to 4 decimal places)

The dimension of the new classroom is 8 meters of length and 5 meters of width.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given that,
Area of the classroom = 20 square meters
Let x be the length and y be the width of the classroom.
Area of a rectangular classroom = Length × Width.
So, we get an equation,
xy = 20
x = 20/y [Equation 1]
If length is increased by 3 meters and the width is increased by 1 meter, the classroom will double in area.
(x + 3) (y + 1) = 20 × 2
(x + 3) (y + 1) = 40 [Equation 2]
Substitute [Equation 1] in [Equation 2]
((20/y) + 3) (y + 1) = 40
Multiplying,
20 + 3y + (20/y) + 3 = 40
3y + (20/y) = 40 - 23
3y + (20/y) = 17
Multiplying throughout by y,
3y² + 20 = 17y
3y² - 17y + 20 = 0
3y² - 12y - 5y + 20 = 0
3y (y - 4) - 5 (y - 4) = 0
(3y - 5) (y - 4) = 0
3y - 5 = 0 or y - 4 = 0
y = 5/3 or y = 4
Let y = 4, then x = 20/4 = 5
Dimension of the new classroom is (x+3) = 8 meters and (y+1) = 5 meters
Hence the dimension of the new classroom is 8 meters and 5 meters.

Make a table comparing a parallelogram, a rectangle, a square, a rhombus, a kite, and a trapezoid, with both descriptions and sketches, including markings for congruency. All work should be original
We have compared a parallelogram, a rectangle, a square, a rhombus, a kite, and a trapezoid, with type, descriptions, and properties.
What is congruency?
The term “congruent” means exactly equal shape and size. This shape and size should remain equal, even when we flip, turn, or rotate the shapes.
Parallelogram: A four-sided shape with opposite sides parallel. Opposite sides are parallel, opposite angles are congruent, diagonals bisect each other.
Rectangle: A four-sided shape with four right angles.
Opposite sides are parallel and congruent, all angles are right angles, diagonals are congruent and bisect each other.
Square: A four-sided shape with four congruent sides and four right angles.
All sides are congruent, all angles are right angles, diagonals are congruent and bisect each other.
Rhombus: A four-sided shape with four congruent sides. All sides are congruent, opposite angles are congruent, diagonals bisect each other, and are perpendicular bisectors of each other.
Kite: A four-sided shape with two pairs of adjacent sides congruent. Diagonals are perpendicular, one diagonal bisect the other, opposite angles are congruent.
Trapezoid: A four-sided shape with one pair of parallel sides.
One pair of opposite sides are parallel, non-parallel sides may or may not be congruent, and diagonals intersect at a point inside the trapezoid.
Hence, we have compared a parallelogram, a rectangle, a square, a rhombus, a kite, and a trapezoid, with type, descriptions, and properties.
