Answer: 200/7
Step-by-step explanation:
This creates 3 similar right triangle
you would put similar parts on top and the similar parts on bottom of proportions.
ex.
[tex]\frac{hypotenuse}{short leg} = \frac{hypotenuse}{short leg}[/tex]
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
You could also make your proportion where
parts of 1 triangle = equivalent parts of the other
ex.
[tex]\frac{long leg from big triangle}{long leg from small triangle} = \frac{short leg big triangle}{short leg from small triangle}[/tex]

The length of a cell phone is 1.4 1.4 inches and the width is 4.2 4.2 inches. The company making the cell phone wants to make a new version whose length will be 1.75 1.75 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answers
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
So the width of the new phone will be 5.25 inches.
Answer:
The answer is 5.25 inches!

Answer:
-10.5
Step-by-step explanation:
Pick two points that the line overlaps. We can see the points are on (0,63) (2,42) and (4,21). Lets use (2,42) and (4,21). To find the rate of change (m) the formula needed is y^2 - y^1 divided by x^2 - x^1. 21-42=-12 over 4-2=2. So we get -10.5 for the rate of change.

Answer:
unable to determine the given data
Step-by-step explanation:
What is mode?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.
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
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.
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

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:

box plot
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.

Answers
Answer:
36.85 ft
Step-by-step explanation:
3 feet on either end + 6 feet on either side + circumference of the circle
3 + 3 + 6 + 6 + circumference of the circle
18 + circumference of the circle
You can find the circle's diameter by subtracting 6 from 12. You get 6. You can find the radius by dividing the diameter by 2. You get 3.
The formula for circumference is 2·π·Radius
2 · π · 3 = 6 · π = 6 · 3.14 ≈ 36.85

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
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.

In the data set below, what is the interquartile range?
23 58 58 64 76 87
Answers
Answer: IQR= 18
Step-by-step explanation:
First, you need to put the numbers in order from least to greatest, which they already are.
23, 58, 58, 64, 76,87
then, you draw an imaginary line down the middle of the numbers (between 58 and 64), and then you find the number in the middle of these. The Q1 is 58, and the Q3 is 76. In order to find the Interquartile range (IQR), you simply subtract the two.
76-58= 18
And you have your answer
Hope this helps!
Answer:
44
Step-by-step explanation:
First, we need to find the median in the data set.
It's between 58 and 64. To find the median, we add those two numbers and then divide by 2.
58 + 64 = 122
122 ÷ 2 = 61 (Mark this point in between the numbers on the data set)
median = 61
23, 58, 58, | 64, 76, 87
Now that we have the median, we have to find the upper quartile and the lower quartile in order to find the interquartile range.
Lets find upper quartile first. In order to do that, add up all the numbers to the right of the data set from the median point, then divide by 2.
64 + 76 + 87 = 227
227 ÷ 2 = 113.5
The same goes for the lower quartile (to the left).
23 + 58 + 58 = 139
139 ÷ 2 = 69.5
Lastly, to find the interquartile range, simply subtract the lower quartile from the upper quartile.
113.5 - 69.5 = 44
Therefore interquartile range = 44.

V is for Volume.
s is for the measurement of the side.
3 is for the length, width, and height.
First, just plug the number in; V=3^3. Or 3×3×3.
Second, Multiply; V=27

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

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 = 0Now, we can divide both sides by -0.75 to isolate x^2:
x^2 = 0/(-0.75)x^2 = 0Taking the square root of both sides, we get:
x = 0Therefore, 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:
