Answer:

[tex]x = \frac{7}{8}[/tex] or [tex]x = 0.875[/tex]

Step-by-step explanation:

Step 1:

[tex]\frac{1}{6} + \frac{1}{12} x ( 7 - 24x) = \frac{8}{3} x (\frac{1}{2} -x)[/tex],

[tex]\frac{1}{6} + \frac{7}{12} - 2x = \frac{8}{3} x (\frac{1}{2} - x)[/tex]

[tex]\frac{1}{6} + \frac{7}{12} - 2x = \frac{4}{3} - \frac{8}{3}x[/tex]

Step 2:

[tex]\frac{1}{6} + \frac{7}{12} - 2x = \frac{4}{3} - \frac{8}{3}x[/tex]

[tex]\frac{3}{4} - 2x =\frac{4}{3} - \frac{8}{3}x[/tex]

Step 3:

[tex]\frac{3}{4} - 2x =\frac{4}{3} - \frac{8}{3}x[/tex]

[tex]9 - 24x = 16 - 32x[/tex]

Step 4:

[tex]9 - 24x = 16 - 32x[/tex]

[tex]9 - 24x + 32x = 16[/tex]

[tex]-24x + 32x = 16 - 9[/tex]

Step 5:

[tex]-24x + 32x = 16 - 9[/tex]

[tex]8x = 16 - 9[/tex]

[tex]8x = 7[/tex]

Step 6:

[tex]x = \frac{7}{8}[/tex]

The mode is the value in a set that appears most often.

In order to identify the mode, we would need the set of numbers.

Because, we are only given the box plot, we cannot find the number that appares the most , so we are unable to determine the given data.

What is the distance traveled by the tip of the second hand of a clock in 1 minute if the hand is 10.5 inches long? Leave your answer in terms of π.

Answers

Answer:

(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Step-by-step explanation:

The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

The time needed for the rocket to be 30 feet of the ground is given as follows:

t = 9.6 seconds.

How to obtain the time needed?

The quadratic function giving the rocket's height after t seconds is given as follows:

h(t) = -16t² + 150t + 70.

The rocket will be 30 feet of the ground when:

h(t) = 30.

Hence:

-16t² + 150t + 70 = 30

16t² - 150t - 40 = 0.

The coefficients of the quadratic function are given as follows:

a = 16, b = -150, c = -40.

Time is a positive measure, hence, using a quadratic function calculator, the positive root is given as follows:

let's say I start something at 10:20 pm on the 18 of April and I finish that thing at 12:06 am 19th of April. How much time did I spend doing that thing (Would like a explaination)

Answers

You started at 10:20 pm on April 18th and finished at 12:06 am on April 19th. This means that the time elapsed is between two different days. To calculate the amount of time spent doing that thing, we need to subtract the start time from the end time.

First, let's convert the start time to 24-hour format, which is 22:20. Then, we can subtract 22:20 from 00:06 (12:06 am).

00:06
- 22:20
____
01:46

Therefore, you spent 1 hour and 46 minutes doing that thing.
You spent 1 hour and 46 minutes.
1 hour is 60 minutes, at 11:00 pm you would have spent 40 minutes doing what you had started so from 10:20pm to 11:00pm 40 minutes passed. Then you would add 60 minutes from 11:00pm to 12:00am.
( although 12:00 is marked as we know that 12:00 am marks the earths rotation of a day which means at 12:00am the sun has begun to reach your point of rotation on earth) from 12:00am to 12:06am it has past 6 minutes

40mins + 60mins+6mins=106mins
1 hour goes into 106mins so
106-60= 46

You spent 1 hour and 46mins

Answer:

x = 19

Step-by-step explanation:

We can see that the angles (2x + 4) and (8x - 14) are supplementary — they add to 180. From this observation, we can form the equation that can be solved for x:

(2x + 4) + (8x - 14) = 180

↓ combining like terms

10x - 10 = 180

↓ adding 10 to both sides

10x = 190

↓ dividing both sides by 10

x = 19

Answers

To find the line parallel to y = -2x - 5 that includes the point (-1, 3), we'll use the same slope (m = -2) since parallel lines have the same slope.

Using the point-slope form: y - y₁ = m(x - x₁)

Plug in the values: y - 3 = -2(x - (-1))

Simplify: y - 3 = -2(x + 1)

Now, we can find the y value of the point:

y - 3 = -2(-1 + 1)
y - 3 = 0
y = 3

So, the y value of the point is 3.

Answer: To use the calculator: Enter the corresponding values into the boxes below and ... to and add to. i) In a quadratic equation in the form ax2 bx c 0, if.

Step-by-step explanation:

According to the information, we can infer that some coordinates of this quadratic equation are: (-2, -3), (-1, -0.75), (0, 0), (1, -0.75), and (2, -3)

How to solve the quadratic equation?

To solve the quadratic equation, we need to set the equation equal to zero:

-0.75x^2 = 0

Now, we can divide both sides by -0.75 to isolate x^2:

x^2 = 0/(-0.75)x^2 = 0

Taking the square root of both sides, we get:

x = 0

Therefore, the solution to the quadratic equation s(x) = -0.75x^2 is x = 0.

According to the previous information, we can infer that the equation s(x) = -0.75x^2 represents a downward facing parabola. Here are 5 possible coordinates on this curve:

Description

A Box and Whisker Plot (or Box Plot) is a convenient way of visually displaying the data distribution through their quartiles.

The lines extending parallel from the boxes are known as the “whiskers”, which are used to indicate variability outside the upper and lower quartiles. Outliers are sometimes plotted as individual dots that are in-line with whiskers. Box Plots can be drawn either vertically or horizontally.

Although Box Plots may seem primitive in comparison to a Histogram or Density Plot, they have the advantage of taking up less space, which is useful when comparing distributions between many groups or datasets.

Here are the types of observations one can make from viewing a Box Plot:

What the key values are, such as: the average, median, 25th percentile, etc.

If there are any outliers and what their values are.

If the data is symmetrical or not.

How tightly is the data grouped.

If the data is skewed and if so, in what direction.

Two of the most commonly used variation of Box Plot are: variable-width Box Plots and notched Box Plots.

in your problem they gave the short legs and long legs of right triangel

The line that they share in middle of the triangle is the long leg for the triangle on right and it is also the short leg for triangle on left.

[tex]\frac{long leg}{short leg} =\frac{long leg}{short leg}[/tex]

[tex]\frac{x}{20} = \frac{20}{14}[/tex]

x=(400)/14 = 200/7

If the side lengths of the new phone are proportional to the old phone, then we can set up a proportion:

1.4/4.2 = 1.75/x

Solving for x, we get:

x = 5.25 inches

In the diagram of a fan below, CA = 9.5 in. this is the distance from the center to a point on the fans blade. what is the distance point A travels in one rotation of the fans blade

Answers

Answer:

About 59.66 inch

Step-by-step explanation:

To find the circumference you first have to find the diameter which is the double the radius. Since 9.5 is the radius of this circle, the diameter is, 9.5x2=19.

With the diameter of 19, you multiply the 19 with pie which is approximately 3.14. The answer is 19x3.14=59.66

We can use the formula for the circumference of a circle to find the distance point A travels in one rotation of the fan's blade. The distance traveled is the same as the circumference of the circle with radius 9.5 in., which is:

C = 2 * pi * r
C = 2 * pi * 9.5
C = 59.69 in.

So point A travels a distance of approximately 59.69 inches in one rotation of the fan's blade.
