Explain how you could use the construction tool or a compass and straightedge to create a line segment that is twice as long as A and B
Answers
So far, segment CD is the same length as AB. So we can say AB = CD.
Let's keep going
Step 6) Place the nonpencil part of the compass at point D and draw another arc to intersect line CD. Make sure you do not intersect at point C, but rather the point on the other side of D. Call this point E. Step 7) Use a marker or pen to highlight everything from C to E. So you'll highlight segment CE. Erase everything else.Segment CE is composed of CD and DE, both of which are equal to AB. In other words, AB = CD = DE. Because CD = DE, and the two segments add up to CE, this must mean that CE is twice as long as CD. Therefore, CE is twice as long as AB.

how many times does 1/4 go into 9/16
Answers
Answer as a fraction = 9/4
Answer in decimal form = 2.25
================================================
Explanation:
1/4 = 4/16 after multiplying top and bottom by 4
We have some number x such that
(4/16)x = 9/16
we can multiply both sides by 16 to clear out the fractions, getting 4x = 9
Then we divide both sides by 4 to get x = 9/4 = 2.25

A wheel has a diameter of 70 cm and completes a revolution in 0.25 seconds at top speed
A) determine the angular velocity, w, in radians per second
B) how far does the the wheel in one minute
Answers
Answer:
8π radians/second527.8 metersStep-by-step explanation:
A) The angular velocity is the ratio of angular distance to time:
ω = 1 revolution / (0.25 s) = (2π radians)/(0.25 s)
ω = 8π radians/second
__
B) The arc length is ...
s = rθ = rωt
s = (35 cm)(8π rad/s)(60 s) = 16,800π cm
s ≈ 52779 cm = 527.79 m
The wheel travels about 527.8 meters in one minute.

A golfer recorded the following scores for each of four rounds of golf: 86, 81, 87, 82. The mean of the scores is 84. What is the sum of the squared deviations of the scores from the mean?
Answers
Answer:
26
Step-by-step explanation:
The mean of a set of number is the average the set of number, it is the ratio of the total sum of the terms to the sum of terms.
The standard deviation is the variation of a set of numbers to their mean. A low standard deviation means the value are close to the mean and a high standard deviation means the values are far from the mean. The standard deviation is given as:
[tex]\sigma=\sqrt{\frac{\Sigma (x_i-\mu)^2}{n} }\\ \\\mu=mean,n=number\ of\ terms, \sigma=standard\ deviation[/tex]
Given the numbers:
86, 81, 87, 82. mean = μ = 84
[tex]\Sigma(x_i-\mu)^2=(86-84)^2+(81-84)^2+(87-84)^2+(82-84)^2=4+9+9+4=26[/tex]
Sum of squared deviations = 26
The sum of the squared deviations of the scores from the mean is 26.
-----------------------
The observations are: 86, 81, 87 and 82.The mean of the observations is 84.The sum of the squared deviations of the scores from the mean is the sum of the differences squared of each observation and the mean.Thus:
[tex]S_{ds} = (86-84)^2 + (81-84)^2 + (87-84)^2 + (82-84)^2 = 4 + 9 + 9 + 4 = 26[/tex]
The sum of the squared deviations of the scores from the mean is 26.

. The Barnaby Corporation issued 2,700,000 shares of stock at its beginning to shareholders.
How many shares must a shareowner own to have a majority of the shares?
Answers
Answer:
1,350,001 shares
Step-by-step explanation:
Barnaby corporation issued 2,700,00 shares of stock to its respective shareholders
A shareholder is required to own more than half of the share of the stock of a corporation inorder to have most of it.
This implies that the shareholder must have 50% + 1 inorder to attain the majority shares
Therefore, the number of shares that must by owned by a shareholder to have majority of the shares can be calculated as follows
= 50/100 × 2,700,000
= 0.5×2,700,000
= 1,350,000+1
= 1,350,001 shares
Please help! I have very limited time to answer, but I am really stumped!
Answers
Answer:
A
Step-by-step explanation:
So we have the function:
[tex]f(x)=y=\sqrt[3]{x-2}+8[/tex]
To find the inverse of the function, we can flip x and y and then solve for y. Therefore:
[tex]x=\sqrt[3]{y-2}+8[/tex]
Solve for y to find our inverse.
Subtract 8 from both sides:
[tex]x-8=\sqrt[3]{y-2}[/tex]
Cube each side. The right cancels:
[tex](x-8)^3=y-2[/tex]
Add 2 to both sides:
[tex]y=(x-8)^3+2[/tex]
Therefore, our inverse is:
[tex]f^{-1}(x)=(x-8)^3+2[/tex]

A school of salmon was swimming in the river 5 feet below the surface. To escape a hungry bear, they went down another 3 feet. What is the position of the salmon now relative to the surface?
Answers
Answer:
8 Feet below the surface
Step-by-step explanation:
If the salmon were initially 5 feet below the surface, and then travelled down an additional 3 feet from the initial 5, then the new position would be 8 feet down relative to the surface.
You can write this as -5 + -3 = -8, assuming that 0 represents surface level.
Cheers.
The distance of salmon from the surface of the water is 8 feet.
What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Given that,
The distance of school of salmon for the surface of the river = 5 feet.
Since, to escape a hungry bear, the school of salmon went down to 3 feet.
The position of the salmon to the surface = 5 + 3 = 8 feet.

The width of a rectangle measures (3.1s-1.6)(3.1s−1.6) centimeters, and its length measures (7.2s-4.6)(7.2s−4.6) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle? A. −6.2+10.3s B. −12.4+20.6s C. 1.5s+2.6 D. 5.2+3s
Answers
Answer:
B. -12.4 + 20.6s.
Step-by-step explanation:
Perimeter = 2*length + 2 * width
= 2(3.1s - 1.6) + 2(7.2s - 4.6)
= 6.2s + 14.4s - 3.2 - 9.2
= 20.6s - 12.4
= -12.4 + 20.6s.
[tex]\boxed{-12+20.6s}[/tex]
To find the perimeter of a shape, we add length + width + length + width (or length * 2 + width *2). So we would multiply the width, (3.1s - 1.6), and the length, (7.2s - 4.6), by 2, and then add them together to find the perimeter.
2(3.1s - 1.6) + 2(7.2s - 4.6)
This is equal to:
6.2s + 14.4s - 3.2 - 9.2
Simplified, this is equal to:
20.6s - 12.4
(We have to switch it around, but this answer is equal to option b.)
-12.4 + 20.6s

A room with poor air quality has a particle concentration of 80 units. A fan removes 50% of the remaining particles each hour. What is the particle concentration, in these same units, in the room after 2 hours?
Answers
Answer:
20 units
Step-by-step explanation:
Initial particle concentration = 80 units
Particles removed each hour = 50% of the remaining particles
To find:
Particle concentration after 2 hours = ?
Solution:
Particles removed in 1 hour = 50% of remaining particles
i.e. Particles removed in 1 hour = 50% of initial concentration
Particles removed in 1 hour = 50% of 80 = 40
Particles removed in next 1 hour = 50% of remaining particles
i.e. Particles removed in next 1 hour = 50% of concentration after 1 hour
Particles removed in next 1 hour = 50% of 40 = 20
Total particles concentration removed in 2 hours = 40 + 20 = 60 units
Therefore, particle concentration after 2 hours = Initial concentration - Total particle concentration removed in 2 hours
= 80 - 60 = 20 units
which line of best fit should not have been drawn. Give a reason for your answer
Answers
Answer:
Diagram B
Step-by-step explanation:
This is because the line only goes through two points and many are dispered from the line, however diagram A and C have points fairly close to them
Visually inspecting the three scatterplots, the line of best fit does not accurately fit the points on the second graph. Hence, line of best fit should not have been drawn for the second graph as the relationship isn't linear.
The line of best fit minimizes the sum of the square of the mean distance between each point. Hence, the distance between the line and the best fit line should be as small as possible.
However, the second graph isn't linear, hence , a linear line cannot model the relationship.

Explanation:
For a parallelogram, we'll have opposite angles with the same measure. So if one angle is 45 degrees, then the opposite angle is also 45 degrees. The other two angles are 180-45 = 135 degrees each. Adjacent angles in a parallelogram add to 180 degrees.
