Marques wants to use a sheet of fiberboard 36 inches long to create a skateboard ramp with a 30 degree angle of elevation from the ground. How high will the ramp rise from the ground at its highest end? Round your answer to the nearest tenth of an inch if necessary.

Answer:

measure of arc JL is 170°

Step-by-step explanation:

The Inscribed Angle Theorem states that the measure of an inscribed angle is half the measure of its intercepted arc. Inscribed angles that intercept the same arc are congruent.

so 85*2 is 170°

Homer would have taken approximately 8.11 hours to do the job by himself.

Let h be the time it would take Homer to do the job by himself, and let m be the time it would take Mike to do the job by himself. We know from the problem that:

m = h - 1 (Mike can do the job one hour quicker than Homer)

We also know that they worked together for 4 hours, so they completed 4/h + 4/m of the job. We can set up an equation based on this:

4/h + 4/m = 1 (they completed the entire job)

Substituting m = h - 1, we get:

4/h + 4/(h-1) = 1

Multiplying both sides by h(h-1), we get:

4(h-1) + 4h = h(h-1)

Simplifying:

8h - 4 =

[tex]h^2 - h[/tex]

Rearranging:

[tex]h^2 - 9h + 4 = 0[/tex]

Using the quadratic formula, we get:

[tex]h = (9 ± \sqrt{(9^2 - 414)) / 2} [/tex]

In the figure angle5 and angle 6 are vertical angles

Vertical angles are a pair of angles formed by two intersecting lines or rays. They are opposite to each other and have equal measures. In other words, if two lines intersect at a point, the angles that are across from each other, or directly opposite each other, are vertical angles.

Vertical angles are always congruent, which means that they have the same angle measurement. This can be proven using the properties of parallel lines and transversals, which state that when a transversal intersects two parallel lines, the alternate interior angles are congruent, and the corresponding angles are congruent.

Since vertical angles are formed by intersecting lines, they are neither adjacent nor supplementary.

The standard deviation is the square root of the variance and is used to measure how spread out the data is. To calculate the standard deviation, take the square root of the variance.

Variance is the measure of how far a set of numbers are spread out from their average value. It is a measure of how much variation or dispersion exists from the average. Variance is represented as the square of the standard deviation, which is a measure of the spread of numbers in a set.

The mean of the data is 18.25. The variance is a measure of the spread of the data away from the mean, and is calculated by taking the average of the squared differences from the mean. To calculate the variance, subtract the mean from each data point, square this result and add up the values. Then divide this sum by the number of data points minus one.

For example, if the data set contains the values 10, 15, 20, 25 and 30 then the mean is 18.25. Subtracting the mean from each data point gives -8.25, -3.25, 1.75, 6.75, 11.75. Squaring each of the differences gives 68.0625, 10.5625, 3.0625, 45.5625, 137.0625. Adding these results together gives 264.3125. Dividing this by 4 (the number of data points minus one) gives 66.075. Taking the square root of this gives 8.1 as the standard deviation.

The variance of the given data is calculated to be 118.63 and the standard deviation is 10.89.

The variance of the data is a measure of how far the data points are spread out from the mean. It is calculated by taking the differences between each data point and the mean, squaring the differences, and then taking the average of those squared differences.

For our data, the mean is 18.25. To find the variance, we can subtract 18.25 from each of the data points and square the differences. Then we can add up all of the squared differences and divide by the number of data points.

Variance = (2 - 18.25)² + (3 - 18.25)² + (4 - 18.25)² + (18 - 18.25)² + (20 - 18.25)² + (25 - 18.25)²

= (15.752 + 14.752 + 13.752 + 0.752 + 1.752 + 6.752) ÷ 6

= (255.2 + 217.2 + 190.2 + 0.6 + 3.0 + 45.8) ÷ 6

The initial velocity required in the roller coaster design is also 26 m/s.

what is an algebraic expression?

An algebraic expression is a mathematical phrase consisting of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

To determine the initial velocity required in a roller coaster design, we can use the conservation of energy principle. At the top of the drop, the total energy of the roller coaster is potential energy, given by mgh, where m is the mass of the roller coaster, g is the acceleration due to gravity, and h is the height of the drop.

At the bottom of the drop, the total energy of the roller coaster is kinetic energy, given by (1/2)mv^2, where v is the velocity of the roller coaster at the bottom.

By equating the two energies, we get:

mgh = (1/2)mv^2

Solving for the initial velocity, we get:

v = sqrt(2gh)

where h is the height of the drop.

Substituting the given values, we get:

v = sqrt(2 x 9.8 m/s^2 x 34 m) = 26 m/s

Therefore, the initial velocity required in the roller coaster design is also 26 m/s.

The autograph of the professional basketball player's was worth $250.00 a year ago.

Given that, in the last year, the value of a professional basketball player's autograph rose 40% and it is now worth $350.00.

To determine it worth a year ago, let's call the original value of the autograph "x".

We know that the value increased by 40%, which means it became:

100% + 40% = 140% of its original value.

We can set up the following equation:

140% × x = 350

(140/100)x = 350

1.4x = 350

To solve for x, we can divide both sides by 1.4:

x = 350 ÷ 1.4

x = 250
