Different sizes of ribbon need to be cut to go around various shapes. All of the following sizes are in inches. π , √5 ,√8 ,2√5
(a)Without using your calculator, approximate the decimal equivalent of each number to the nearest tenth.
(b)Order the ribbon sizes from least to greatest. Use the original numbers given.
Answers
[tex] \pi = \frac{12.5}{2(2)} [/tex]
[tex] \pi = \frac{12.5}{4} [/tex]
[tex] \pi =3.125[/tex]
And to the nearest tenth:
[tex] \pi =3.1[/tex]
To approximate [tex] \sqrt{2} [/tex], we are going to use the Babylonian method:
Step 1. We are going to make a guess. Our guess is 2 because [tex] \sqrt{4} =2[/tex], so [tex] \sqrt{5} [/tex] must be close to 2.
Step 2. We are going to divide 5 by 2:
[tex] \frac{5}{2} =2.5[/tex]
Step 3. We are going to find the average between our initial guest and the result of our previous calculation:
[tex] \frac{2+2.5}{2} = \frac{4.5}{2} =2.25[/tex]
And to the nearest tenth: [tex] \sqrt{5} =2.2[/tex]
To approximate [tex] \sqrt{8} [/tex], we are going to use the Babylonian method one more time:
Step 1. Our guess is 3 because [tex] \sqrt{9} =3[/tex], so [tex] \sqrt{8} [/tex] must be close to 3.
Step 2. We are going to divide 8 by 3:
[tex] \frac{8}{3} =2.6[/tex]
Step 3. We are going to find the average between our initial guest and the result of our previous calculation:
[tex] \frac{3+2.6}{2} = \frac{5.6}{2} =2.8[/tex]
[tex] \sqrt{8} =2.8[/tex]
To approximate [tex]2 \sqrt{5} [/tex] we are going to multiply our approximation of [tex] \sqrt{5} [/tex] and multiply it by 2:
[tex]2 \sqrt{5} =2*2.2[/tex]
[tex]2 \sqrt{5}=4.4[/tex]
(b) Since we have our irrational numbers expressed as decimal approximations, we can compare them to arrange them form least to greatest:
2.2,2.8,3.1,4.4
Now, we just need to replace the decimal approximations with the original numbers:
[tex] \sqrt{5} [/tex],[tex] \sqrt{8} [/tex],[tex] \pi [/tex],[tex]2 \sqrt{5} [/tex]
We can conclude that ordering the ribbon sizes from least to greatest we get:
[tex] \sqrt{5} [/tex],[tex] \sqrt{8} [/tex],[tex] \pi [/tex],[tex]2 \sqrt{5} [/tex]
The area of the base of the regular quadrilateral pyramid is 36 cm2 and the area of a lateral face is 48 cm2. Find: Surface area of the pyramid
Answers
Answer:
The surface area of the pyramid is [tex]228\ cm^{2}[/tex]
Step-by-step explanation:
we know that
The surface area of the Pyramid is equal to
[tex]SA=B+LA[/tex]
where
B is the area of the base of the pyramid
LA is the lateral area of the pyramid
In this problem we have
[tex]B=36\ cm^{2}[/tex]
Find the lateral area LA
Remember that the lateral area is the area of its four lateral faces
so
Multiply the area of a lateral face by 4 (because is a regular quadrilateral)
[tex]LA=(4)(48)=192\ cm^{2}[/tex]
Find the surface area SA
substitute the values
[tex]SA=36+192=228\ cm^{2}[/tex]
The surface area of the pyramid is 228 square cm.
What is the regular quadrilateral pyramid?A pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex.
The area of the base of the regular quadrilateral pyramid is 36 cm2 and the area of a lateral face is 48 cm2.
The surface area of the pyramid is;
[tex]\rm Surface \ area=B + LA[/tex]
Where; B is the area of the base of the pyramid, LA is the lateral area of the pyramid.
The area of a lateral face by 4 (because is a regular quadrilateral) is;
[tex]\rm LA=4(48)=192[/tex]
Substitute all the values in the formula;
[tex]\rm Surface \ area=B + LA\\\\\rm Surface \ area=36+192\\\\\rm Surface \ area=228[/tex]
Hence, the surface area of the pyramid is 228 square cm.

1+7x=x+4
6x=3
x=.5
First, let's combine like terms.
-3x + 1 + 10x = x + 4
7x + 1 = x + 4
Now, subtract the one from the left. (we do this to combine terms)
7x + 1 = x+ 4
7x = x + 3
Now subtract the x from the right. (this is also to combine terms)
7x = x + 3
6x = 3
Finally, divide by 6 on both sides.
6x = 3
x = 1/2 or 0.5

Anne plans to increase the prices of all the items in her store but 5%. To the nearest cent how much will an artist saved if the artist buys a canvas and a frame that each measures 24 by 36 in before the price increase goes into effect. 24/36 canvas price 22.80 and the frame price is 89.98
Answers
The artist will not save any money, but will end up paying $24.06 more after the price increase.
Explanation:To find out how much the artist will save, we first need to calculate the original cost of the canvas and frame. The price of the canvas is $22.80 and the frame is $89.98. Next, we calculate the price increase of 5% for both the canvas and frame. To do this, we multiply the original prices by 0.05. After that, we add the price increase to the original prices to get the new prices. Finally, we subtract the new prices from the original prices to find the amount saved by the artist.
The calculations are as follows:
Canvas price increase: $22.80 x 0.05 = $1.14New canvas price: $22.80 + $1.14 = $23.94Frame price increase: $89.98 x 0.05 = $4.50New frame price: $89.98 + $4.50 = $94.48Amount saved: ($22.80 + $89.98) - ($23.94 + $94.48) = $94.36 - $118.42 = -$24.06The artist will actually end up paying $24.06 more after the price increase, rather than saving any money.

A recent poll taken by the movie theatre industry shows that 28% of the population attends a movie in a theater at least once a month. A sample of 300 people shows that only 12% of people attends a movie in a theater at least once a month. To determine whether this sample supports the population proportion of 0.28, a simulation of 100 trials is run, each with a sample size of 200 and a point estimate of 0.12. The minimum sample proportion from the simulation is 0.10, and the maximum sample proportion from the simulation is 0.28. What is the margin of error of the population proportion using half the range?
Answers
Answer:
The margin of error for this population proportion using half the range = ±0.09
Step-by-step explanation:
Confidence Interval is basically an interval of range of values where the true proportion can be found with a certain level of confidence.
Margin of Error is the width of the confidence interval about the central proportion.
For this question, the minimum sample proportion from the simulation is 0.10, and the maximum sample proportion from the simulation is 0.28, hence, the confidence interval for the question is (0.10, 0.28).
The width of this confidence interval = (Upper limit of the interval) - (Lower limit of the interval) = 0.28 - 0.10 = 0.18.
Hence, the margin of error for this population proportion using half the range, is 0.18/2 = 0.09.
Written appropriately as ±0.09.

if the length of an arc is 12π inches and the radius of the circle us 10 inches, what is the measure of the arc?
Answers
Thus, s = (12pi inches) = (10 inches)(theta), so
theta = the central angle (not the measure of the arc) = (12pi)/(10 inches), or
theta = 1.2*pi (no units of measurement)
Answer:
The measure of arc is 216°
Step-by-step explanation:
Length of arc, L = 12π inches
Radius of the circle, R = 10 inches
Formula: [tex]\theta=\dfrac{L}{R}[/tex]
Where, [tex]\theta[/tex] in radian.
By substituting L and R into formula.
[tex]\theta=\dfrac{12\pi}{10}[/tex]
[tex]\theta=\dfrac{6\pi}{5}[/tex]
Now we change radian to degree
[tex]\text{Degree }=\dfrac{\text{Radian}}{\pi}\times 180^\circ[/tex]
[tex]\text{Degree }=\dfrac{6\pi}{5\pi}\times 180^\circ[/tex]
Central angle = 216°
Hence, The measure of arc is 216°

what is the equation of a circle with a center located at (4,-1) and a radius of 9
Answers
The equation for a circle with the given information would be (x - 4)^2 + (y + 1)^2 = 81.
This is because the base form of a circle is:
(x - x1)^2 + (y - y1)^2 = r^2
In which, x1 is the x coordinate of the center and y1 is the y coordinate of the center. r is the radius of the circle. So we plug in to those and simplify.
(x - 4)^2 + (y - -1)^2 = 9^2
(x - 4)^2 + (y + 1)^2 = 81
If lines L and M are parallel in the given diagram and angle 5 is 132°, what is the measure of angle 3?
Answers
The answer is 48 degrees.
How I got my answer:
Angle 5 + Angle 3 = 180(Co. Interior Angles)
let Angle 3 be x
132 + x = 180
x = 180 - 132
x = 48
The measure of Angle 3 is 48 degrees.
Hope this helps you.
Since lines L and M are parallel, corresponding angles such as angle 5 and angle 3 will be equal. Thus, if angle 5 is 132°, angle 3 will also be 132°.
Explanation:This question concerns parallel lines and the angles formed by a transversal cutting across them. The lines L and M in the given diagram are parallel. Parallel lines have a special property where corresponding angles are equal. If angle 5 measures 132°, then the corresponding angle, angle 3, also measures 132°, because of this property of parallel lines.
