Step-by-step explanation:
The following D Tether ball pole shadow: 0.6\,\text{m}0.6m0, point, 6, start text, m, end text Flagpole shadow: 1.36\,\text{m}1.36m1, point, 36, start text, m, end text and E Tether ball pole shadow: 2\,\text{m}2m2, start text, m, end text Flagpole shadow: 4.8\,\text{m}4.8m could be the lengths of the shadows. Correct Option is 4 and 5.
Let's assume "x" is the length of the tether ball pole shadow, and "y" is the length of the flagpole shadow.
According to the information given, the proportional relationship can be expressed as:
Tether ball pole height / Tether ball pole shadow length = Flagpole height / Flagpole shadow length
The height of the tether ball pole is 333 meters, and the height of the flagpole is 6.8 meters.
So, we have the following equation:
333 meters / x = 6.8 meters / y
Now, let's solve for "y" in each choice and check which choices satisfy the proportional relationship:
Choice A:
333 / 1.35 = 6.8 / 3.4
246.67 ≈ 2
Choice B:
333 / 1.8 = 6.8 / 4.08
185 ≈ 1.67
Choice C:
333 / 3.75 = 6.8 / 8.35
88.8 ≈ 0.81
Choice D:
333 / 0.6 = 6.8 / 1.36
555 ≈ 5
Choice E:
333 / 2 = 6.8 / 4.8
166.5 ≈ 1.42
The two choices that satisfy the proportional relationship are:

Sarai is mixing a solution. She pours all the liquid from a full small beaker into a larger beaker. The liquid fills the large beaker to 15% of its capacity. If the small beaker holds 300 mL, how much does the large beaker hold?
Answer:
2000 ml
Step-by-step explanation:
Given: Sarai pours all the liquid from a full small beaker into a larger beaker.
The liquid fills the large beaker to 15% of its capacity.
The small beaker holds 300 ml.
Lets assume capacity of large beaker to hold be "x".
As given, Sarai pours all the liquid from a full small beaker into a larger beaker
∴ [tex]15\% \times x= 300\ ml[/tex]
⇒ [tex]0.15x= 300[/tex]
Dividing both side by 0.15
⇒[tex]x= \frac{300}{0.15}[/tex]
∴ [tex]x= 2000\ ml[/tex]
Hence, the large beaker can hold 2000 ml of liquid.

Step-by-step explanation:
A line passes through the origin and through points A(−2, b−14) and B(14−b, 72). What is the greatest possible value of b?
Answer:
The greatest possible value for b is 26.
Step-by-step explanation:
Given that the line passes through the Origin O(0, 0); A(-2, b - 14) &
B(14 - b, 72).
Let us assume the points are in the order: AOB.
Since the line passes through all these points the slope of the line segment AO = The slope of the line segment AB.
Slope of a line with two points: [tex]$ \frac{y_2 - y_1}{x_2 - x_1} $[/tex] where [tex]$ (x_1, y_1) $[/tex] and [tex]$ (x_2, y_2) $[/tex] are the points given.
[tex]$ (x_1, y_1) = (0,0) $[/tex]
[tex]$ (x_2, y_2) = (-2, b - 14) $[/tex]
Therefore, the slope of the line segment AO = [tex]$ \frac{b - 14}{-2} $[/tex]
Similarly, for the slope of the line segment OB.
The two points are [tex]$ (x_1, y_1) = (0, 0) $[/tex] and [tex]$ (x_2, y_2) = (14 - b, 72) $[/tex].
The slope is: [tex]$ \frac{72}{14 - b } $[/tex]
Since, the slopes are equal we can equate:
[tex]$ \frac{b - 14}{-2} = \frac{72}{14 - b} $[/tex]
[tex]$ \implies \frac{b - 14}{-2} = \frac{72}{-(b - 14)} $[/tex]
[tex]$ \implies (b - 14)^2 = 72 \times 2 = 144 $[/tex]
[tex]$ \implies (b - 14)^2 = 12^2 $[/tex]
Taking square root on both sides we get:
[tex]$ \implies (b - 14) = \pm 12 $[/tex]
[tex]$ \implies b = 2 \hspace{2mm} or \hspace{2mm} 26 $[/tex]
Therefore, the maximum value of b = 26.
Hence, the answer.

A snowboard is on sale for $476. If the
original price was $560, what is the
percent discount?
Answer:
15%
Step-by-step explanation:
we call the original price 100% and to find the discount amount :
Multiply 100 by $476 then divide by $560
100 × $476 ÷ $560 = 85
$476 is 85% of the original price therefore the amount of discount as in percentage is 100 - 85 = 15%
The perimeter of a rectangle must be less than 172 feet. If the length is known to be 53 feet, find the range of possible widths for the rectangle. (Note: The formula for the perimeter of a rectangle is P=2l+2w , where l is the length and w is the width).
Express your answer in interval notation. Use decimal form for numerical values.
Answer:
1 - 32.5
Step-by-step explanation:
If the perimider is less then 172, that the limit is 171. 171 - (53)2 = 65. divide that by the two sides that are the width it equals 32.5
Perimeter is the sum of the length of the sides used to make the given figure. The range of the width of the rectangle is (0,33).
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
Given that the perimeter of a rectangle must be less than 172 feet. Also, given that the length of the rectangle is 53 feet. Therefore, we can write inequality of the width of the rectangle as,
2(Length) + 2(Width) < Perimeter
2(53 feet) + 2(Width) < 172 feet
106 feet + 2(Width) < 172 feet
2(Width) < 172 feet - 106 feet
2(Width) < 66 feet
Width < 66feet / 2
Width < 33 feet
Hence, the range of the width of the rectangle is (0,33).

RS and ST are 2 sides of a regular 12-sided polygon.
RT is a diagonal of the polygon.
Work out the size of angle STR.
You must show your working.
Answer:
15°
Step-by-step explanation:
The exterior angle at vertex S is 360°/12 = 30°. That angle has a measure that is equal to the sum of the congruent angles at R and T of ΔRST. In other words, ...
∠T = 30°/2 = 15°
The size of angle STR is 15°.
The sides of a regular polygon are congruent.
The size of STR is 15 degrees
The polygon is 12-sided.
This means that:
[tex]\mathbf{n =12}[/tex]
The sum of angles in a regular hexagon is 360.
So, the angle at vertex S is:
[tex]\mathbf{\theta = \frac{360}{n}}[/tex]
This gives
[tex]\mathbf{\theta = \frac{360}{12}}[/tex]
[tex]\mathbf{\theta = 30^o}[/tex]
The external angle of a triangle equals the sum of the opposite internal angles.
This means that:
[tex]\mathbf{\theta = \angle STR + \angle SRT}[/tex]
Where:
[tex]\mathbf{ \angle STR = \angle SRT}[/tex]
So, we have:
[tex]\mathbf{\theta = \angle STR + \angle STR}[/tex]
[tex]\mathbf{\theta = 2\angle STR}[/tex]
Substitute [tex]\mathbf{\theta = 30^o}[/tex]
[tex]\mathbf{30^o = 2\angle STR}[/tex]
Divide both sides by 2
[tex]\mathbf{15^o = \angle STR}[/tex]
Rewrite as:
[tex]\mathbf{\angle STR = 15^o }[/tex]
Hence, the size of STR is 15 degrees

The width of a rectangular painting is 3in. More than twice the height. A frame that is 2.5 in. Wide goes around the painting
Question:
A width of a rectangular painting is 3 in. More than twice the height. A frame that is 2.5 in. Wide goes around the painting
a. write an expression for the combined area of the painting and frame.
b. use the expression to find the combined area when the height of the painting is 12 in.
c. use the expression to find the combined area when the height of the the painting is 15 in.
Answer:
a) (h + 5)(2h + 8) is the expression for the combined area of the painting and frame
b) The combined area when h = 12 is 544 square inches
c) The combined area when h = 15 is 760 square inches
Solution:
Given that,
A frame that is 2.5 inches wide goes around the painting
The frame will go around all 4 sides of the painting.
That means that the length of each side of the painting will increase by 2.5 inches
Therefore,
The height of painting and frame is:
h = h + 2.5 + 2.5
h = h + 5
(2.5 inches on the top and the bottom)
Also given that,
Width of a rectangular painting is 3 inches more than twice the height
w = 3 + 2h
Now the width of painting and frame is:
w = 3 + 2h + 2.5 + 2.5
(Again, 2.5 inches on the top and the bottom)
w = 2h + 8
Thus the combined area of the painting and frame is:
[tex]Combined\ area = (h+5)(2h+8)[/tex]
B) Substitute h = 12 inches
[tex]Combined\ area = (12+5)(2(12)+8)\\\\Combined\ area = 17 \times (24+8) = 17 \times 32\\\\Combined\ area = 544[/tex]
Thus the combined area when h = 12 is 544 square inches
C) Substitute h = 15 inches
[tex]Combined\ area = (15+5)(2(15)+8)\\\\Combined\ area = 20 \times (30+8) = 20 \times 38\\\\Combined\ area = 760[/tex]
Thus combined area when h = 15 is 760 square inches
