To find the measure of the central angle ∅ in radians, given the radius of a circle and the length of an arc, we can use the formula ∅ = s/r, where s is the length of the arc and r is the radius of the circle which is 3π / 4.

The formula to calculate the measure of the central angle ∅ in radians is ∅ = s/r, where s is the length of the arc and r is the radius of the circle.

Given the radius of the circle as 4 cm and the length of the arc AB as 3π cm, we can substitute these values into the formula:

∅ = (3π) / 4

Simplifying the expression:

∅ = 3π / 4

Therefore, the measure of the central angle ∅ in radians is 3π/4.

In a class with a ratio of boys to girls of 5:7, the total number of students can range from 25 to 43. The exact number of students cannot be determined without additional information.



We are given the ratio of boys to girls in the class, which is 5:7. This means that for every 5 boys, there are 7 girls. To determine the total number of students in the class, we need to find a number that satisfies this ratio and falls within the given range of 25 to 43.Let's assume the number of boys is 5x and the number of girls is 7x, where x is a positive integer. The total number of students in the class is then 5x + 7x = 12x. We want to find a value for x that gives a total number of students between 25 and 43.

By testing different values of x within a reasonable range, we can determine the possible number of students. Starting with x = 2, we have 12x = 24, which is below the given range. Increasing x to 3, we have 12x = 36, which falls within the range. Therefore, a class with 3 boys and 7 girls would have a total of 36 students.If we continue testing larger values of x, we find that when x = 4, 12x = 48, which is above the given range. Therefore, the number of students can be determined to be 36. It's important to note that without any additional information or constraints, there could be multiple valid solutions within the given range.

0.6 / 0.3 = 2

To test this answer:

2 x 0.3 = 0.6

Answer:

x = 0.25

Step-by-step explanation:

If y varies inversely with x, then:

\(y \propto \dfrac{1}{x} \implies y=\dfrac{k}{x} \quad \textsf{(for some constant k)}\)

Given:

Substitute the given values into the found equation and solve for k:

\(\implies 1.6=\dfrac{k}{0.5}\)

\(\implies k=1.6(0.5)\)

\(\implies k=0.8\)

Therefore:

\(y=\dfrac{0.8}{x}\)

To find the value of x when y = 3.2, substitute y = 3.2 into the found equation and solve for x:

\(\implies 3.2=\dfrac{0.8}{x}\)

\(\implies x=\dfrac{0.8}{3.2}\)

The Ruben collected 26/9 bins of bottles, which can also be expressed as a mixed number: 2 8/9 bins.

To start, we need to find out how many bins of bottles Darell collected. We know that he collected 2/3 of a bin.

Next, we need to figure out how many bins Ruben collected. We are told that Ruben collected 4 1/3 times as many bins as Darell. To calculate this, we first need to convert the mixed number 4 1/3 to an improper fraction.

This is done by multiplying the whole number by the denominator and adding the numerator, then putting that answer over the denominator. In this case, 4 times 3 is 12, plus 1 is 13. So 4 1/3 as an improper fraction is 13/3.

To find out how many bins Ruben collected, we multiply Darell's 2/3 bin by Ruben's fraction of 13/3 bins. Multiplying fractions involves multiplying the numerators (top numbers) and denominators (bottom numbers) separately, then simplifying if possible. So, (2/3) x (13/3) = 26/9.

Step-by-step explanation:

For question 30, the first choice is not necessarily true. I attached a picture of what *could* be the parallelogram.

The first choice is true ONLY if the parallelogram is a square.

The second choice is not necessarily true either. It is true ONLY if the parallelogram is a rhombus (a square is also a rhombus, just for reference)

But opposite sides of a parallelogram are always equal

So the answer to question 30 are the first and second choices.

For question 31:

remember what I said about how opposite sides of a parallelogram are always equal? Well opposite angles are also always equal.

So angle BKX = angle BWX = angle XWB = 114 degrees

Angle BKW = angle XWK (using parallel lines) = angle XWB - angle BWK = 114 - 22 = 92 degrees

Angle WBX = angle BXK (using parallel lines too) = angle WXK - angle WXB.

Consecutive angles in a parallelogram add up to 180. So angle WXK + angle XWK = 180. angle WXK = 180 - angle XWK = 180 - 114 = 66 degrees.

angle WDB + angle WBX + angle BWK = 180 because it's a triangle

angle WDB + 66 (just figured it out) + 22 (given) = 180 degrees

angle WDB = 180 - 66 - 22 = 92 degrees

I hope I didn't do anything wrong lol

but I prolly did XD

Answer:

angle WDB + angle WBX + angle BWK = 180 because it's a triangle

angle WDB + 66 + 22 (given) = 180 degrees

angle WDB = 180 - 66 - 22 = 92 degrees

The True Statement is

A. If P'Q'R'S' is formed by translating PQRS 4 units to the right and 5 units down, then PQRS is not necessarily equal to P'Q'R'S'.

Translation is a rigid transformation that preserves the shape and size of the original figure but may change its position.

B. If P'Q'R'S' is formed by reflecting PQRS over the x-axis and then over the y-axis, then PQRS is not necessarily equal to P'Q'R'S'.

Double reflection over perpendicular lines is equivalent to a 180-degree rotation, which may change the orientation of the original figure.

C. If P'Q'R'S' is formed by rotating PQRS 60° about the origin, then PQRS is not necessarily equal to P'Q'R'S'.

Rotation preserves the shape and size of the original figure but changes its orientation and position.

D. If P'Q'R'S' is formed by rotating PQRS 90° clockwise about point Q, and P"Q"R"S" is formed by rotating P'Q'R'S 270° counterclockwise, then PQRS = P"Q"R"S".

The total rotation is equivalent to a 180-degree rotation about point Q, which preserves the shape and size of the original figure.

E. If P'Q'R'S' is formed by reflecting PQRS over the line y=x and P"Q"R"S" is formed by rotating P'Q'R'S 90° clockwise, then PQRS = P"Q"R"S". Reflecting over the line y=x is equivalent to a 90-degree counterclockwise rotation, so the two transformations cancel each other out, and the resulting figure is congruent to the original.

To form a triangle, the set of line segments must satisfy 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. Therefore, we need to check if the given line segments 8 cm, 4 cm, and 3 cm meet this requirement.

We can start by checking if the sum of the two smaller sides (3 cm and 4 cm) is greater than the largest side (8 cm). 3 cm + 4 cm = 7 cm, which is less than 8 cm. Therefore, these three line segments cannot form a triangle.

In general, for a set of line segments to form a triangle, the largest side must be smaller than the sum of the other two sides. In this case, the line segment of 8 cm is too long compared to the other two sides, which makes it impossible to form a triangle.

In conclusion, there are no line segments that meet the requirements to form a triangle with lengths of 8 cm, 4 cm, and 3 cm.

Explanation:

Let's find the width of the microscope slide in meters.

1000 mm = 1 m

1 mm = 1/1000 m

1 mm = 0.001 m

50*(1 mm) = 50*(0.001 m)

50 mm = 0.05 m

50 mm = 5 × 10^(-2) m

The microscope slide is 5 × 10^(-2) meters across. Divide this over the width of one hair.

5 × 10^(-2) ÷ 2.5 × 10^(-5)

(5/2.5) × 10^(-2 - (-5) )

2 × 10^(-2 + 5)

2 × 10^3

This converts to the number 2000. So we could have 2000 strands of hair side by side.

Answer:

(A)  2 * 10^3.

Step-by-step explanation:

50 millimeters = 0.05 m

= 5 * 10^-2 meters.

So, we divide this by the diameter of 1 hair:

= (5 * 10^-2) /  (2.5 * 10 ^ - 5)

= (5/2.5) * (10/^-2 / 10^-5)

= 2 * 10^(-2-(-5))

= 2 * 10^3.

8 hours shift because you count from 7 am to 3pm

The total number of hours between the 7 am and 3 pm shift is 8 hours.

What is meant by the hour?

Depending on the speed of the Earth's rotation, an hour is a measure of time that is traditionally calculated as 1/24  of a day and scientifically estimated to last between 3,599 and 3,601 seconds. There are 24 hours in a day and 60 minutes in an hour.

The 24-hour day is divided into two sections, a.m. and p.m., according to the 12-hour clock time convention. Latin terminology for the hours of the day, AM and PM, are commonly employed. The abbreviations AM and PM stand for Ante meridiem and Post meridiem, respectively, which indicate before noon or midday and afternoon or midday. AM is used to denote the first 12-hour period, which runs from midnight to noon, and PM is used to denote the following 12-hour period, which runs from noon to midnight.

From 7 am to 12 pm, the number of hours = 5

From 12 pm to 3 pm, the number of hours = 3

Therefore the total number of hours between the 7 am and 3 pm shift is (3+5) = 8 hours.

tan(41π/36) can be written in terms of the tangent of a positive acute angle as (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

To express tan(41π/36) in terms of the tangent of a positive acute angle, we need to find an angle within the range of 0 to π/2 that has the same tangent value.

First, let's simplify 41π/36 to its equivalent angle within one full revolution (2π):

41π/36 = 40π/36 + π/36 = (10/9)π + (1/36)π

Now, we can rewrite the angle as:

tan(41π/36) = tan((10/9)π + (1/36)π)

Next, we'll use the tangent addition formula, which states that:

tan(A + B) = (tan(A) + tan(B)) / (1 - tan(A)tan(B))

In this case, A = (10/9)π and B = (1/36)π.

tan(41π/36) = tan((10/9)π + (1/36)π) = (tan((10/9)π) + tan((1/36)π)) / (1 - tan((10/9)π)tan((1/36)π))

Now, we need to find the tangent values of (10/9)π and (1/36)π. Since tangent has a periodicity of π, we can subtract or add multiples of π to get equivalent angles within the range of 0 to π/2.

For (10/9)π, we can subtract π to get an equivalent angle within the range:

(10/9)π - π = (1/9)π

Similarly, for (1/36)π, we can add π to get an equivalent angle:

(1/36)π + π = (37/36)π

Now, we can rewrite the expression as:

tan(41π/36) = (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

Since we are looking for an angle within the range of 0 to π/2, we can further simplify the expression as:

tan(41π/36) = (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

Therefore, tan(41π/36) can be written in terms of the tangent of a positive acute angle as the expression given above.
