Answer:

6 chaperones on 80 students.

Step-by-step explanation:

Here is the complete question: School guideline required that there must be 2 chaperones for every 25 students on a school trip. how many chaperones must there be for 80 students?

Given: There must be 2 chaperones on every 25 students.

Now, we will use unitary method to solve.

We know 2 chaperones = 25 students

∴ one student required [tex]\frac{2}{25}\ chaperones[/tex]

Next for 80 students, we require= [tex]\frac{2}{25} \times 80 = \frac{160}{25}[/tex]

∴ For 80 students, we require [tex]6.4 \ chaperones[/tex], however, we cannot use decimal for number of person, so we can round off the number to 6 chaperones on every 80 students.

7 1/4

You subtract 20 and 2/4 by 12 3/4 and you get 8 1/4

The equation of the line is y = 2x+ 5.

1. Identify the slope:

Lines are considered parallel if they have the same slope.

To find the slope of the given line, we can rearrange the equation 4x-2y=8 to slope-intercept form (y = mx + b) by isolating y: y = 2x - 4.

Therefore, the slope of both the given line and the parallel line we want to find is 2.

2. Use the point-slope form:

We can use the point-slope form of the equation to create the equation of the new line: y - y₁ = m(x - x₁)

Substituting the known point (-2, 1) and the slope (2): y - 1 = 2(x - (-2))

Simplifying the equation: y - 1 = 2x - 4

Combining like terms: y = 2x + 5

Therefore, the equation of the line that passes through (-2, 1) and is parallel to the line 4x-2y=8 is y = 2x + 5.

To find a parallel line to 4x-2y=8 that passes through (-2, 1), we determine the slope of the given line (which is 2) and use point-slope form to write the equation of the new line, resulting in y = 2x + 5.

The student is asking for the equation of a line that passes through a specified point and is parallel to a given line. The equation of the existing line is 4x-2y=8. To find a parallel line, we must have the same slope. First, let's find the slope of the given line by rewriting its equation in slope-intercept form (y=mx+b), where m is the slope and b is the y-intercept. The original equation is 4x - 2y = 8, which can be rewritten as y=2x-4. Thus, the slope is 2.

Since the new line must be parallel, it will also have a slope of 2. Using the point-slope form of a line, which is y - y1 = m(x - x1), where (x1,y1) is the point the line passes through, we substitute the point (-2,1) and the slope of 2 to get the equation y - 1 = 2(x + 2). Simplifying this, we get y = 2x + 5 as the equation for the line that is parallel to 4x-2y=8 and passes through the point (-2, 1).

Answer:

We know that

P(X) = Dividor × Quotient

So dividor = x-1

Quotient = x2 + 7 + 5/x-1

So,

P(x) = x3 - x2 + 7x -2

Step-by-step explanation:

Taking LCM of quotient we will get

(x3 - x2 + 7x - 2)/(x-1)

Now by multiplying the above equation with x-1,

Only thing remaining will be

x3 - x2 + 7x - 2

This is P(x).

The polynomial p(x) in standard form, when given the quotient formed from dividing p(x) by (x - 1), is x^3 - x^2 + 7x - 2.

The function p(x) can be expressed in standard form by multiplying divisor (x - 1) by the quotient, (x^2 + 7 + 5/(x - 1)) according to polynomial division rules. To get p(x), you multiply the quotient by the divisor and add the remainder. However, since there is no remainder mentioned, we assume it's zero and ignore it.

Therefore, p(x) is (x - 1)(x^2 + 7 + 5/(x - 1)). To simplify further, distribute (x - 1) across each term in the parenthesis:

So, the polynomial p(x) is x^3 - x^2 + 7x - 7 + 5 or, simplified further, x^3 - x^2 + 7x - 2.

Step-by-step explanation:

Final answer:

The area of triangle ABC with vertices A(-1, -1), B(3, -1), and C(-1, 2) is calculated using the determinant method and results in 6 square units.

Explanation:

To find the area of a triangle with vertices on a coordinate plane, you can use the formula that requires knowing the coordinates of all three vertices.

For triangle ABC with vertices A(-1, -1), B(3, -1), and C(-1, 2), we can use the determinant method:

The area of triangle ABC is ½ |x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)|. Substituting our given coordinates into this formula, we get:

Area = ½ |(-1)(-1 - 2) + 3(2 - (-1)) + (-1)((-1) - (-1))|

Area = ½ |(-1)(-3) + 3(3) + (-1)(0)|

Area = ½ |3 + 9 + 0|

Area = ½ × 12

Area = 6 square units

The area of triangle ABC is therefore 6 square units.

Answer:

  110

Step-by-step explanation:

You want the remainder from the division ...

  [tex]\dfrac{4x^3+2x^2-18x+38}{x-3}[/tex]

The remainder theorem tells you the remainder of ...

  f(x)/(x -a)

We can compute f(a) directly, or we can do it using synthetic division. The attachment shows the synthetic division approach.

If we want to evaluate f(x), it is convenient to write it in Horner Form:

  f(x) = 4x³ +2x² -18x +38 = ((4x +2)x -18)x +38

Then, for x = 3, this is ...

  ((4·3 +2)·3 -18)·3 +38 = (14·3 -18)·3 +38 = 24·3 +38 = 110

The remainder from the division is 110.

Answer:

2i: 169.71

2ii: 0.17L

3a: 4×10⁻⁵

3b: 110011

Step-by-step explanation:

2i. The surface of the top and bottom of the tin is two times (top and bottom) π·r² = 2·π·3² = 18π cm².

The circumference of the circle is 2·π·r = 6π cm².

The area of the material connecting top and bottom is a rectangle of the tin height times the circumference: 6·6π = 36π cm².

This gives a total of  18π + 36π = 54π  cm².

With π approximated by 22/7 the total surface area is 54*22/7 ≈ 169.71.

Notice how the calculation is simple by waiting until the very last moment to substitute π.

2ii. The volume is the area π·r² of the circle times the height of the tin: 9π*6 = 54π cm³ ≈ 169.71 cm³.

Since 1L = 1000 cm³ the volume is 0.16971 litres, which should be rounded to 0.17 L.

3a: If we rewrite P as 36 x 10⁻⁴ and realize that 36/2.25 = 16, then the fraction can be written as

16 x 10⁻⁴⁻⁶ = 16 x 10⁻¹⁰.

The square root of that is taking it to the power of 1/2, so (16x10⁻¹⁰)^0.5 = 4x10⁻⁵ = 0.00004

Triangle with sides RS=19, SQ = 20, AND QR = 18 must have unequal angles as triangles with unequal sides have unequal angles.

A triangle with unequal sides is known as the Scalene triangle. As mentioned in the question triangle QRS has unequal sides of length RS = 19, SQ = 20, and QR = 18.

Then we can say that triangle Δ QRS is a Scalene triangle.

A scalene triangle has unequal angles. It has no line of symmetry present in a  scalene triangle.

In a scalene triangle, the angle opposite to the longest side is the greatest.

Hence, we can say that the angles of  Δ QRS are unequal.

https://brainly.com/question/17335144

The correct statement is that at least two angles of ΔQRS are equal, and one angle is different.

Here,

In a triangle, the sum of the measures of the three interior angles is always 180 degrees.

This is known as the triangle angle sum property.

Therefore, if we know the lengths of two sides of a triangle, you can determine the measure of the third angle using the Law of Cosines or the Law of Sines.

In the case of ΔQRS, we can use the Law of Cosines to find the measure of angle ∠Q:

Cos(∠Q) = (RS² + QR² - SQ²) / (2 * RS * QR)

Cos(∠Q) = (19² + 18² - 20²) / (2 * 19 * 18)

Cos(∠Q) = (361 + 324 - 400) / (2 * 19 * 18)

Cos(∠Q) = 285 / 684

Cos(∠Q) ≈ 0.416667

Now, to find the measure of ∠Q, we take the inverse cosine (arccos) of 0.416667:

∠Q ≈ arccos(0.416667) ≈ 65.392°

Now that we know the measure of ∠Q, we can find the measures of the other angles:

∠R = 180° - ∠Q - ∠S

∠R = 180° - 65.392° - ∠S

And

∠S = 180° - ∠Q - ∠R

∠S = 180° - 65.392° - (180° - 65.392° - ∠S)

∠S = 180° - 65.392° - 180° + 65.392° + ∠S

∠S = 2 * 65.392° - ∠S

2 * ∠S = 2 * 65.392°

∠S = 65.392°

So, the measures of the angles in ΔQRS are approximately:

∠Q ≈ 65.392°

∠R ≈ 49.608°

∠S ≈ 65.392°

As we can see, two of the angles (∠Q and ∠S) are equal, while the third angle (∠R) is different.

Therefore, the correct statement is that at least two angles of ΔQRS are equal, and one angle is different.

Answer:

The number of years in which saving gets double is 8 years .

Step-by-step explanation:

Given as :

The principal amount saved into the account = p = $8,000

The rate of interest applied = r = 9%

The Amount gets double in n years = $A  

Or, $A = 2 × p = $8,000 × 2 = $16,000

Let the number of years in which saving gets double = n years

Now, From Compound Interest method

Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]

Or, 2 × p = p × [tex](1+\dfrac{\textrm r}{100})^{\textrm n}[/tex]

Or, $16,000 = $8,000 × [tex](1+\dfrac{\textrm 9}{100})^{\textrm n}[/tex]

Or, [tex]\dfrac{16,000}{8,000}[/tex] = [tex](1.09)^{n}[/tex]

Or, 2 = [tex](1.09)^{n}[/tex]

Now, Taking Log both side

[tex]Log_{10}[/tex]2 = [tex]Log_{10}[/tex] [tex](1.09)^{n}[/tex]

Or, 0.3010 = n × [tex]Log_{10}[/tex]1.09

Or, 0.3010 = n × 0.0374

∴ n = [tex]\dfrac{0.3010}{0.0374}[/tex]

I.e n = 8.04 ≈ 8

Answer:

1 point

Step-by-step explanation:

The number of games in the tournament is:

₄C₂ = 6

Another way to look at it: Team 1 plays 3 games against Team 2, 3, and 4.  Then, Team 2 plays 2 games against Team 3 and 4 (Team 2 already played Team 1).  Finally, Team 3 plays a game against Team 4.  So the total is 3 + 2 + 1 = 6.

If there's a total of 6 games, then there's a total of 6 points.  So if x is the number of points Team 4 has:

x + 1 + 3 + 1 = 6

x + 5 = 6

x = 1

Team 4 has 1 point.

The domain of the function f(x) = (2/5) * sqrt(x) is all real numbers x ≥ 0, or in interval notation, [0, ∞). This is because square roots are only defined for non-negative real numbers.

The domain of a function refers to all possible values that can be input into the function, usually represented by 'x'. For the given function f(x) =  \frac{2}{5} \sqrt{x}, we need to determine the set of x-values for which the function is defined. Since we cannot take the square root of a negative number in the set of real numbers, the smallest value for 'x' must be 0. Thus, the domain of the function f(x) = \frac{2}{5} \sqrt{x} includes all real numbers greater than or equal to 0.

This is written mathematically as “x ≥ 0” or in interval notation as [0, ∞). It's important to note that, for real numbers, square roots are only defined for non-negative values, which is why the domain starts at 0 and continues to positive infinity.

Using the cross product property on this proportion gives us the following equation:

6 (3x + 3) = 7 (x + 16)

Use the distributive property

18x + 18 = 7x + 112

Subtract both sides by 7x

11x + 18 = 112

Subtract both sides by 18

11x = 94

Divide both sides by 11

x = 94/11

This fraction is already fully simplified and cannot be simplified further. This should be your answer.

Let me know if you need any clarifications, thanks!

Answer:

Step-by-step explanation:

6(3x+3) = 7(x+16)
