The solutions to the inequality s < 30 are 20%, 17%, 29 and one-half percent (which is equivalent to 29.5%), and 1.5%.
The disparity that best illustrates the phrase "the possibility of snow is less than 30%" is:
s < 30
This implies that the inequality can be solved for any value of s that is less than 30.
We must compare the numbers to 30 and see if they are less than it in order to identify which ones are the answers to the inequality.
The answer is yes because 20% = 0.2 is less than 30%.
It is not a solution because 35% = 0.35 is not less than 30%.
The answer is yes because 17% = 0.17 is less than 30%.
It is not a solution because 30% = 0.3 is not less than 30%.
That is a solution since 29 and a half percent = 0.295 is less than 30%.
The answer is yes because 1.5% = 0.015 is less than 30%.
As a result, the answers to the inequality s 30 are 20%, 17%, 29 and a half percent (or 29.5%), and 1.5 percent.

The measure of angle WUX is 78⁰.
option D.
What is the measure of angle WUX?
The measure of angle WUX is calculated by applying the following triangle principles.
∠ VUX + ∠VXU = 90 ( complimentary angles )
7x + 11 + 11x + 7 = 90
18x + 18 = 90
18x = 72
x = 72/18
x = 4
The measure of angle VXU is calculated as;
∠VXU = 11x + 7
= 11 x 4 + 7
= 51⁰
The measure of angle UWV is calculated as;
∠ UWV = 6x + 27
= 6 x 4 + 27
= 51⁰
The measure of angle WUX is calculated as;
∠ WUX = 180 - ( 51 + 51 ) ( sum of angles in a triangle )
∠ WUX = 180 - 102

ordered pairs of x=7y+2
Answer: The equation x = 7y + 2 is a linear equation in two variables, x and y. To find ordered pairs of x and y that satisfy this equation, we can choose values of y and then solve for x.
For example, if we choose y = 0, then:
x = 7y + 2
x = 7(0) + 2
x = 2
Therefore, the ordered pair (2, 0) satisfies the equation x = 7y + 2.
Similarly, if we choose y = 1, then:
x = 7y + 2
x = 7(1) + 2
x = 9
Therefore, the ordered pair (9, 1) satisfies the equation x = 7y + 2.
We can continue in this manner to find more ordered pairs. However, note that there are infinitely many ordered pairs that satisfy this equation, as the equation represents a line with a slope of 7 and a y-intercept of (0, 2). Therefore, we can choose any value of y and obtain a corresponding value of x that satisfies the equation.

Consider parallelogram ABCD below.
Use the information given in the figure to find x, m
Answer:
x = 3 ; ∠m B = 85° ; ∠m BAC = 34°
Step-by-step explanation:
Opposite sides of a parallelogram are equal. If 2x = 6, then x must be equal to 3. The same idea goes for angles. Since angle D measures 85°, angle B must as well. Using the formula 180°(n-2), where n = number of sides, it is seen that there are 180°(2) = 360° in a four sided shape. Knowing two of them, we can subtract 85*2 from 360 to find the rest of the degrees. 360° - 170° = 190°. Since the other two angles are equal as well, 190°/2 = 95°. Since ∠m DAC = 61°, ∠m BAC must equal 95°-61°, which is equal to 34°

Which of the following describes an approach used to harness tidal energy?
I. Floating platform with turbines
II. Floating ship with turning pendulum
III. Having water spin turbines attached to fence
I only
II only
I and II
I, II, and III
Sure! Tidal energy is a type of renewable energy that is harnessed from the movement of ocean tides. There are different approaches to harnessing tidal energy, but the three options given in the question are:
I. Floating platform with turbines: This approach involves anchoring a floating platform in the tidal zone, where the rise and fall of the tides can be used to turn turbines and generate electricity. The turbines are connected to generators, which convert the mechanical energy of the turning turbines into electrical energy. This approach is commonly used in commercial tidal energy projects, such as the MeyGen tidal energy project in Scotland.
II. Floating ship with turning pendulum: This approach, also known as the "pendulor" or "pendulum" system, involves a floating ship or barge that is anchored in the tidal zone. The ship is designed to swing back and forth with the movement of the tides, and this movement is used to turn a pendulum, which in turn drives a generator. The idea behind this approach is that the ship's movement can be used to generate more energy than just the up-and-down motion of a floating platform with turbines. However, this approach is still in the experimental phase and has not yet been deployed on a commercial scale.
III. Having water spin turbines attached to fence: This approach involves installing turbines directly in the flow of tidal currents. The turbines are attached to a fence-like structure, which guides the flow of water and increases the speed of the current as it passes through the turbines. The spinning turbines generate electricity, which is then sent to a generator and converted into usable power. This approach is also known as "barrage" or "fence" technology, and it has been used in a few commercial tidal energy projects, such as the La Rance tidal power plant in France.
So, to answer the question, the correct answer is "I and III" since both involve using turbines to generate electricity from the movement of ocean tides.
Floating platform with turbines and Having water spin turbines attached to fence best describes an approach used to harness tidal energy.
What is Energy?Energy is the capacity to do work
The approach used to harness tidal energy is described by option I and III.
I. Floating platform with turbines - This involves placing turbines on floating platforms that are anchored to the seabed.
As the tide comes in and out, the water flows through the turbines, generating electricity.
III. Having water spin turbines attached to fence - This involves building a fence-like structure across a tidal inlet.
As the tide comes in and out, the water flows through the fence and spins turbines, generating electricity.
Option II, floating ship with turning pendulum, does not describe an approach used to harness tidal energy.
Therefore, floating platform with turbines and having water spin turbines attached to fence best describes an approach used to harness tidal energy.

Thomas loves tomatoes. He plans to fill the container shown below with soil to grow his own tomato plants. The dimensions of the container are shown in inches.
How much soil will the container hold?
Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi.
The required container can hold approximately 1570.8 cubic inches of soil.
Explain about Container.By enclosing units in containers—that is, by circling, boxing, or otherwise enclosing units—container numbers indicate magnitude. The worth of each container's contents is multiplied by the number system's fundamental unit. Typically, the basis is either 2 or 10 (the decimal system) (the binary system).
According to question:To find the volume of the container, we can use the formula for the volume of a cylinder:
[tex]$$ V = \pi r^2 h $$[/tex]
where r is the radius of the base (half the diameter) and $h$ is the height of the cylinder.
In this case, the diameter of the container is 10 inches, so the radius is half that, or 5 inches. The height is given as 20 inches. Substituting these values into the formula, we get:
[tex]$$ V = \pi (5\text{ in})^2 (20\text{ in}) = \pi (25\text{ in}^2)(20\text{ in}) \approx 1570.8 \text{ in}^3 $$[/tex]
Therefore, the container can hold approximately 1570.8 cubic inches of soil.

What is Motion?Motion is the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed.
here, we have,
From the question, we are to determine the maximum height of the boulder
First, we will calculate the time it took the boulder to reach its maximum height
Using the formula,
v = u - gt
Where v is the final velocity
u is the initial velocity
g is the acceleration due to gravity (g = 32.1741 ft/s²)
and t is the time
From the given information
u = 122 ft/s
At maximum height, v = 0 ft/s
Putting the parameters into the equation, we get
0 = 122 - 32.1741t
32.1741t = 122
t = 3.79 s
This means it takes the boulder 3.79 seconds to reach its maximum height.
Now, substitute the value of t into the function that gives the height of the boulder
From the given information,
The height of the boulder is given by
H(t)= -16t² + 122t + 10
Then,
H(3.79) = -16(3.79)² + 122(3.79) + 10
H(3.79) = -229.8256 + 462.38 + 10
H(3.79) = 242.5544
H(3.79) ≅ 242.6 ft
Hence, the boulder's maximum height is 242.6 feet.

According to given information the correct answer is [tex]$t =[/tex] [tex]\frac{5}{4}$[/tex] seconds.
What is Equations?An equation is a mathematical statement that asserts the equality of two expressions. It typically consists of two expressions separated by an equals sign (=), with the expression on the left side equal to the expression on the right side. The equals sign indicates that the two expressions have the same value for some or all values of the variables involved.
The equation that gives the height [tex]($S$)[/tex] of the ball at time [tex]($t$)[/tex] is:
[tex]$$S = 140 + 128t - 16t^2$$[/tex]
To find the time [tex]($t$)[/tex] when the ball is at a certain height, we can set the equation equal to that height and solve for [tex]t$.[/tex]
For example, if we want to find the time when the ball is at a height of 200 feet, we would set [tex]$S = 200$[/tex] and solve for [tex]t$:[/tex]
[tex]$$200 = 140 + 128t - 16t^2$$[/tex]
Rearranging and simplifying, we get:
[tex]$$16t^2 - 128t + 60 = 0$$[/tex]
Dividing both sides by 4, we get:
[tex]$$4t^2 - 32t + 15 = 0$$[/tex]
We can solve for [tex]$t$[/tex] using the quadratic formula:
[tex]$$t[/tex]= [tex]\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$[/tex]
where [tex]a = 4$, $b = -32$,[/tex] and [tex]c = 15$.[/tex]
Plugging in these values, we get:
[tex]$$t[/tex] = [tex]\frac{-( -32) \pm \sqrt{(-32)^2 - 4(4)(15)}}{2(4)}$$[/tex]
Simplifying, we get:
[tex]$$t =[/tex] [tex]\frac{32 \pm \sqrt{484}}{8}$$[/tex]
[tex]$$t =[/tex][tex]\frac{32 \pm 22}{8}$$[/tex]
Therefore, the possible values of [tex]$t$[/tex] are:
[tex]$$t =[/tex] [tex]\frac{7}{2} \quad \text{or} \quad t = \frac{5}{4}$$[/tex]
Since the ball is thrown upward, the time when the ball is at a height of 200 feet is the time it reaches the height of 200 feet on its way up, not on its way down.
Therefore, according to given information the correct answer is [tex]$t =[/tex] [tex]\frac{5}{4}$[/tex] seconds.
