Answer:

Absolute error = $25

Step-by-step explanation:

Given that:

Amount spent by John on shopping trip = $75

Estimated amount to spent on shopping trip = $100

Absolute error = Approximate value - Exact value

Here,

Approximate value = $100

Exact value = $75

Absolute error = 100 - 75

Absolute error = $25

Percentage = \(\frac{Absolute\ error}{Exact\ value}*100\)

Percentage = \(\frac{25}{75}*100\)

Percentage = 33.33%

Hence,

Absolute error = $25

hello hope you are having a good day

the answer to your question would be A 6 miles i took the test and got an 100% also asked the teacher.

Given:

The table of value and y is inversely proportional to square of x.

To find:

The value of c and d.

Solution:

It is given that y is inversely proportional to square of x. So,

\(y\propto \dfrac{1}{x^2}\)

\(y=k\dfrac{1}{x^2}\)               ...(i)

Where, k is the contant of proportionality.

From the given table it is clear that \(y=4\) and \(x=3\). Putting these values in (i), we get

\(4=k\dfrac{1}{3^2}\)

\(4=\dfrac{k}{9}\)

\(4\times 9=k\)

\(36=k\)

Putting \(k=36\) in (i), we get

\(y=36\dfrac{1}{x^2}\)

\(y=\dfrac{36}{x^2}\)             ...(ii)

Putting \(x=5,y=c\) in (ii), we get

\(c=\dfrac{36}{(5)^2}\)

\(c=\dfrac{36}{25}\)

Putting \(x=d,y=2\) in (ii), we get

\(2=\dfrac{36}{d^2}\)

\(d^2=\dfrac{36}{2}\)

\(d^2=18\)

Taking square root on both sides, we get

\(d=\pm \sqrt{18}\)

\(d=\pm 3\sqrt{2}\)

Therefore, the required values are \(c=\dfrac{36}{25}\) and \(d=\pm 3\sqrt{2}\).

The measure of angle ZCBD is 90°. Therefore, the correct option is J. 90.

To find the measure of angle ZCBD, we need to examine the given information.

From the figure, we know that angle CDE is 155°.

Since the opposite angles of a rectangle are congruent, angle BCD is also 155°.

In a rectangle, the sum of the interior angles at a vertex is always 90°.

Therefore, angle CBD is 90°.

Hence, the measure of angle ZCBD is 90°.

Therefore, the correct option is J. 90.

Answer:

Amber jack 22 pounds

Tarpon 110 pounds

King fish = 44 pounds

White Marlin = 88 pounds

Step-by-step explanation:

Let the weight of the amber jack be x pounds

Kingfish weighed twice as much = 2 * x = 2x pounds

White Marlin weighed 2 times kingfish

= 2x * 2 = 4x pounds

Tarpon weighs 5 times amber jack = 5 * x = 5x

Add all together to give 264

5x + 4x + 2x + x = 264

12x = 264

x = 264/12

x = 22 pounds

Hence ;

Amberjack weighs 22 pounds

Tarpon = 5 * 22 = 110 pounds

Kingfish = 2 * 22 = 44 pounds

White Marlin = 2 times king fish = 2 * 44 = 88 pounds

The sine of the smallest of the angles in the triangle is;

SinA = √{(√5 - 1)/2}.

A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding terms. This ratio is regarded as one of the geometric sequence's common ratios.

Now, according to the question;

Consider right angled triangle ΔABC ; right angled at C.

The side opposite to each vertices A,B,C are a, b, c respectively.

Thus, by Pythagorean theorem,

a² + b² = c²   (equation 1)

By geometric sequence;

a² = bc (say);

Also, a/c = √(b/c)

substitute  in equation 1

b² + bc - c² = 0

Divide equation by c².

b²/c² + b/c - 1 = 0  (equation 2)

Consider vertex B.

The sine of angle B; sinB = Perpendicular/Hypotenuse

SinB = b/c = t (say)

Substitute b/c by t in equation 2

t² + t -1 = 0

Calculate the roots of the equation by quadratic formula;

t = (√5 - 1)/2 and (-√5 - 1)/2 (negative value is not possible for side)

Thus, t = (√5 - 1)/2

Also SinA = a/c = √(b/c)

SinA = √{(√5 - 1)/2}

Therefore, the sine of the smallest of the angles in the triangle is;

SinA = √{(√5 - 1)/2}.

Part A: An open circle on a number line represents an excluded value, indicating that the endpoint is not included in the solution set of the inequality. It is used when the inequality includes the symbols < (less than) or > (greater than), which denote strict inequality.

Part B: A closed circle on a number line represents an included value, indicating that the endpoint is part of the solution set of the inequality. It is used when the inequality includes the symbols ≤ (less than or equal to) or ≥ (greater than or equal to), which denote inclusive inequality.

Part C: The shading on the number line represents the range of values that satisfy the given inequality. It indicates which values make the inequality true. Typically, the shading is done to the right or left of the circle(s) depending on whether the inequality is greater than or less than.

Part A:

For example, if we have the inequality x > 2, we would represent it with an open circle at 2 on the number line. This means that 2 itself is not a valid solution, but any value greater than 2 is included.

Part B:

For example, if we have the inequality x ≥ -3, we would represent it with a closed circle at -3 on the number line. This means that -3 itself is a valid solution, as well as any value greater than or equal to -3.

Part C:

For example, if we have the inequality x > 2, we would shade the portion of the number line to the right of the open circle at 2. The shaded region represents all the values greater than 2 that satisfy the inequality. The shading visually illustrates the solution set and helps identify the range of valid values for the variable in the given inequality.

Answer: 42

Step-by-step explanation: you have to add 9 18 and 15.

To make the system singular, we need the coefficient of one of the variables to be a multiple of the coefficient of the same variable in the other equation. Let's choose b = 4, which makes the first equation a multiple of the second:

2x + 4y = 16

4x + 8y = g

To make the system solvable, we need the two equations to not be parallel, which means the slopes must be different. Let's choose g = 32, which gives the second equation a slope of 1/2:

2x + 4y = 16

4x + 8y = 32

We can solve this system using substitution or elimination. Let's use elimination:

-2(2x + 4y = 16) -> -4x - 8y = -32

4x + 8y = 32

0 = 0

We see that the last equation is always true, which means the system has infinitely many solutions. We can find two solutions by setting x = 0 and solving for y:

2(0) + 4y = 16

y = 4

So one solution is (0,4). Now let's set y = 0 and solve for x:

2x + 4(0) = 16

x = 8

So another solution is (8,0).

According to the questions there are 5000 students at mountain high school, and 3/4 of these students are seniors. Then, 2125 students do not favor the idea of forming a debate team

To find the number of students who do not favor the idea of forming a debate team, we need to calculate the following:

Number of senior students: 3/4 * 5000 = 3750

Number of senior students in favor: 1/2 * 3750 = 1875

Number of non-senior students: 5000 - 3750 = 1250

Number of non-senior students in favor: 4/5 * 1250 = 1000

Number of students not in favor: Total students - (Senior students in favor + Non-senior students in favor)

Number of students not in favor: 5000 - (1875 + 1000) = 2125

Therefore, 2125 students do not favor the idea of forming a debate team.

Answer:

The swimmer's resultant vector can be found by drawing a right triangle with the northward velocity as one leg and the westward velocity as the other leg. The hypotenuse of this triangle represents the swimmer's resultant velocity. The angle Ө0 between the northward velocity and the resultant velocity can be found using the inverse tangent function: tan⁻¹(2.1/6.4) = 18.19°. So, the direction of the swimmer's resultant vector is 18.19° west of north.

Answer:

108.17° (nearest hundredth)

Step-by-step explanation:

In order to find the direction the person is swimming, we must find the direction of the resultant vector of the two vectors representing 6.4 m/s north and 2.1 m/s west, measured counterclockwise from the positive x-axis.

Since the two vectors form a right angle, we can use the tangent trigonometric ratio.

\(\boxed{\begin{minipage}{7 cm}\underline{Tangent trigonometric ratio} \\\\$ \tan x=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $x$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\end{minipage}}\)

The resultant vector is in quadrant II, since the swimmer is travelling north (positive y-direction) and is being pushed by a current moving west (negative x-direction).

As the direction of a resultant vector is measured in an anticlockwise direction from the positive x-axis (and the resultant vector is in quadrant II), we need to add 90° to the angle found using the tan ratio.

The angle between the y-axis and the resultant vector can be found using tan x = 2.1 / 6.4. Therefore, the expression for the direction of the resultant vector θ is:

\(\theta=90^{\circ}+\arctan \left(\dfrac{2.1}{6.4}\right)\)

\(\theta=90^{\circ}+18.1659565...^{\circ}\)

\(\theta=108.17^{\circ}\; \sf (nearest\;hundredth)\)

Therefore, the direction of the swimmer's resultant vector is approximately 108.17° (measured anticlockwise from the positive x-axis).

This can also be expressed as N 18.17° W.
