The amount of material needed by Marta to make the flag is;

\(\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}\) square inch.

The total cost of making the flag is;

\(\rm 0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}\) dollar.

Given

Marta is making a flag with the given dimensions.

The perimeter of the flag is 100 inches.

Let us consider that the flag has a triangular shape.

According to the Hero's formula;

The area of the triangle is given by;

\(\rm Area =\sqrt{s(s-a)(s-b)(s-c)}\)

Where, s is the semi perimeter and a, b, and c are the sides of the triangle.

Semi perimeter s = P/2,

Since the perimeter of the flag is 100 inches.

\(\rm S=\dfrac{100}{2}\\\\S=50\)

The dimensions of triangular shape are \(\rm d_1, d_2 \ and \ d_3\).

Then,

The area of the triangular flag becomes;

\(\rm Area =\sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}\)

So the amount of material needed to make the flag is;

\(\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}\)

Therefore,

The cost of material = C = $0.15 per square inch

So the total cost in making the flag will be;

\(\rm C\times A=0.15 \times A\\\\=0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}\).

Hence, The amount of material needed by Marta to make the flag is \(\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}\).

The unit of measurement used is A. Standard deviation is the unit of measurement used to describe how far a set of values are from the mean.

The degree of variation of data from the average, or mean, is gauged by the standard deviation. It provides us with information on the average amount by which each data point diverges from the mean.

A lesser standard deviation suggests that the data points gather closely around the mean, whereas a greater standard deviation signifies that the data points are further dispersed. To standardize a value, we subtract the mean from the value and then divide by the standard deviation.

If abcde is a regular pentagon, the smallest rotation about e which maps a to d is 144 degrees.

Using the fact that a regular pentagon has rotational symmetry of order 5. This means that if we rotate the pentagon by 72 degrees around its center, it will appear the same as it did before the rotation.

To map a to d, we need to rotate the pentagon by some angle around point e. Since e is the center of rotation, we need to find an angle that is a multiple of 72 degrees.

To determine the smallest angle of rotation, we need to find the number of 72 degree rotations that take us from a to d.

Starting from a, we can count the number of 72 degree rotations we need to make to reach d. We see that we need to make two 72 degree rotations in a counterclockwise direction.

Therefore, smallest rotation about e that maps a to d is a 144 degree counterclockwise rotation.

We can visualize this by drawing a regular pentagon and marking the point a and d on it. Then, we draw a line segment from a to d and a line segment from e to the midpoint of segment ad.

The angle between these two line segments is 144 degrees.

The distance traveled by Jasmine and Chelsea is given by the equations of speed and J = 20.4 km and C = 39 km , where T is the time taken and T = 0.6 hours

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed of Jasmine be represented as S₁ = 34 km/h

Let the speed of Chelsea be represented as S₂ = 65 km/h

Now , the distance traveled by Jasmine = J

And , the distance traveled by Chelsea = C

The measure of J = measure of C

So , the distances are the same

Let the time taken by both Jasmine and Chelsea be T

Now , Speed = Distance / Time

Substituting the values in the equation , we get

Distance D = 34T

And , distance D = 65T

Now , the total distance D = 59.4 km

So , 34T + 65T = 59.4

On simplifying the equation , we get

99T = 59.4

T = 0.6 hours

Step-by-step explanation:

The equation of the line that passes through the point (−11,−14) is y = x - 3.

What is the slope of the line?

A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).

We have,

The line that passes through the point (−11,−14)

With Slope (m) = 1,

The general equation of a straight line is

y = mx + c,

where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

so here,

y = mx + c,

(-14) = 1(-11) + c

c = -14 + 11

c = -3

The equation becomes:

We can simplify the expression by combining like terms: 4AA - CTBTCTBT. Finally, the simplified expression is 4AA - CTBTCTBT.

To simplify the given expression (2AT - BC)T 2A + CTBT, let's break it down step by step:

Step 1: Transpose (2AT - BC)

The first step is to transpose the matrix 2AT - BC. Transposing a matrix means flipping it over its main diagonal. In this case, we have:

(2AT - BC)T = (2AT)T - (BC)T

The transpose of a scalar multiple of a matrix is the same as the scalar multiple of the transpose of the matrix, so we have:

(2AT)T = 2A and (BC)T = CTBT

Substituting these values back into the expression, we get:

(2AT - BC)T = 2A - CTBT

Step 2: Multiply by 2A + CTBT

Next, we multiply the result from step 1 by 2A + CTBT:

(2A - CTBT)(2A + CTBT)

To simplify this expression, we can use the distributive property of matrix multiplication. When multiplying two matrices, we distribute each term of the first matrix to every term of the second matrix. Applying this property, we get:

(2A)(2A) + (2A)(CTBT) - (CTBT)(2A) - (CTBT)(CTBT)

Note that the order of multiplication matters in matrix multiplication, so we need to be careful with the order of terms.

Simplifying further, we have:

4AA + 2ACTBT - 2ACTBT - CTBTCTBT

The approximate volume of sand in the container is about 0.2 gallons. To find the volume of the sand, we need to find the volume of the cylinder container. We can use the formula for the volume of a cylinder: V=πr²h.

First, we need to find the radius by dividing the diameter by 2: r = 12/2 = 6. So, the volume of the cylinder is: V = 3.14 x 6² x 10 = 1,128 cubic inches. To convert cubic inches to gallons, we divide by 231 (the number of cubic inches in a gallon): 1,128/231 ≈ 4.9 gallons. Rounding this to the nearest gallon gives us 5 gallons.

However, the child completely filled the container with sand, which means that some sand may have spilled over the top. So, it's safe to assume that the actual volume of sand in the container is slightly less than 5 gallons. We can estimate the volume to be about 0.2 gallons.

Question 1

The angles 52 degrees match up. So if the sides are in proportion, then the triangles are similar.

Notice how 8/12 = 18/27 is a true equation. So the sides are in proportion to one another.

Therefore, the triangles are similar. I used the SAS similarity theorem.

================================================================

Question 2

Let's find the missing angle of the triangle on the right. For now, make that missing angle to be x.

Rule: For any triangle, the three angles always add up to 180

x+70+32 = 180

x+102 = 180

x = 180-102

x = 78

The missing angle of the triangle on the left is 78 degrees

Repeat for the other triangle as well

y+78+32 = 180

y+110 = 180

y = 180-110

y = 70

Both triangles have the angles 32, 70, 78 in whatever order you wish.

Since the angles match up like this, the triangles are similar because of the AA Similarity theorem

Technically, we only need 2 pairs of congruent angles at minimum. But having 3 congruent pairs doesn't hurt either.

================================================================

Question 3

We have a pair of congruent 54 degree angles shown. There's another pair of angles at the very top that overlap (aka shared angles).

Since we have two pairs of congruent angles, the two triangles are similar.

This time we use the AA Similarity theorem

================================================================

Question 4

Let's divide the longest side of the bottom triangle by the longest side of the triangle on top

48/32 = 1.5

Now let's divide the shortest sides of each triangle in the same order

36/24 = 1.5

Repeat for the middle-most sides

45/30 = 1.5

We get the same linear scale factor 1.5 each time. Therefore, the triangles are similar due to the SSS Similarity theorem

================================================================

Question 5

Any angle is equal to itself due to the reflexive property. So that will go for reason number 2.

Reason 3 is SAS similarity because we have the sides in proportion (statement 1) and the angles are congruent (statement 2).

Where the above is given, the required angle m∠BAC = 45°.

In triangle ABC. AC represents the foreman’s line of sight to the top of the landfill. Landfill height is BC

The triangle is geometric shape which includes 3 sides and sum of interior angle should not grater than 180°

According to conditions angle b = 90°

The sum of angles of a triangle= 180°

That is a + b + c = 180

Therefore, c = a

       a = (180 - b)/2

          = (180 - 90) / 2

          = 90 / 2

          = 45°

Hence, the required angle m∠BAC = 45°

The slope of the tangent line to the polar curve r = 2 - sin(θ) at the point specified by θ = π/3 is -1/2.

To find the slope of the tangent line to the polar curve r = 2 - sin(θ) at the point specified by θ = π/3, we need to first find the derivative of r with respect to θ, and then evaluate it at θ = π/3.

Differentiating both sides of the polar equation with respect to θ, we get:

dr/dθ = d/dθ(2 - sinθ)

dr/dθ = -cosθ

So, the derivative of r with respect to θ is -cosθ.

Evaluating this derivative at θ = π/3, we get:

dr/dθ|θ=π/3 = -cos(π/3) = -1/2

Therefore, the slope of the tangent line to the polar curve r = 2 - sin(θ) at the point specified by θ = π/3 is -1/2.

The student needs a minimum score of 84.5 on the fourth test to ensure a grade of B.

To find the minimum score the student needs on the fourth test, we can use the formula for the average of four numbers:

Average = (sum of the numbers) / 4

We know that the student needs an average of at least 80 to earn a grade of B, and we also have the scores for the first three tests: 77, 77.25, and 81.25. So, we can set up the equation:

80 = (77 + 77.25 + 81.25 + x) / 4

where x is the score the student needs on the fourth test. Solving for x:

80 = (235.5 + x) / 4

320 = 235.5 + x

x = 320 - 235.5

x = 84.5
