Answer:
a) See attached image
b) AA (or AAA) similarity; either one is correct
c) The statue is 22 meters tall
Step-by-step explanation:
Let's assume the height of the statue is h (to be determined)
a) First let's create a diagram to model this scenario. See attached image
One of the properties of a mirror reflection is that the angle of incidence i.e. the angle at which light strikes the mirror = angle of reflection i.e. the angle at which the light reflects off the mirror
These angles are shown as α and β in the diagram
The two triangles we choose to solve this problem are
ΔABC and ΔCED
Given that ∠BCA is a complementary angle to angle of reflection and ∠ECD is complementary to the angle of incidence, it follows that
m∠BCA = m∠CED
m∠BAC of ΔABC = m∠ECD of ΔECD = 90°
Therefore the third angles of both triangles are also equal
b) By the AA (or AAA) or Angle-Angle Similarity theorem, the two triangles are similar
Therefore the ratio of the sides must be the same for corresponding sides
Therefore
[tex]\dfrac{AB}{DE} = \dfrac{AC}{CD} \\\\Given AD = 12, CD = 3\\\\\dfrac{AD}{CD} = \dfrac{12}{3}= 4\\\\\therefore \\\\\dfrac{AB}{ED} = 4\\\\[/tex]
Since ED is the height of the girl = 5.5 meters and AB = height of the statue = h
we get
[tex]\dfrac{h}{5.5} = 4\\\\h = 4 \times 5.5\\\\h = 22\\\\[/tex]
Answer (c) height of statue = 22 meters

(a)[2 pts] what is the notation of the sample mean? find the sample mean. (b)[3 pts] find the five-number summary of the sample.
a) Sample mean is arithmetic average of data values. The sample mean of provide data values is 10.
b) The five-number summary of the sample is minimum = 4, Q1 = 4.5, median = 9 , Q3 = 15.5 and maximum= 16.
The population mean is denoted by greek letter, μ and sample mean is a random variable; which is written as x-bar and x-bar stands for individual values it takes. The sample mean is a statistic measure obtained by calculating the arithmetic mean of sample values ( values of variable in sample). The sample mean formula is: x-bar = ( Σxᵢ) / n
x-bar represents the “sample mean”Summation notation, Σ, which means “sum up”xᵢ, all of the x-values or data values n means the number of values in the sampleNow, we have to calculate sample mean of following data values, 12,8,15,16,5,4.
Sum of values, Σ xi = 12 + 8 + 15 + 5 + 4 + 16 = 60
Number of values = 6
So, Sample mean, = ( Σ xi ) / n = 60/6 = 10
The five-number summary includes following :
Minimum data value.Q₁ (the first quartile ).Median.Q₃ (the third quartile).maximum data value.So, Steps to determine the five-number summary:
Put your numbers in ascending order.Determine minimum( smallest number) and maximum (largest number) value.Determine the median. The median is the middle number, in case of odd number of data values and in case even set of data the meadian is equals to average of the (n/2)ᵗʰ and the (n/2 + 1)ᵗʰ terms.Place parentheses around the numbers above and below the median.Determine Q₁ and Q₃. Q₁ is median in the lower half of the data, and Q₃ is median for the upper half of data.Now, the sample set is 12,8,15,16,5,4. Arrange the data values in ascending order, 4,5,6,12,15,16. So, Minimum value
= 4 , Maximum value = 16 ,Median = mean of 6 and 12 = (6 + 12)/2 = 9. The vales written as(4, 5, ) 6, 12, (15, 16 ). The value of first quartile, Q₁ = median of lower ( 4,5) = (4+5)/2
= 9/2 = 4.5. Similarly, Third quartile, Q₃
= (15+16)/2= 31/2 = 15.5. Thus, the five-numer summary is minimum = 4, Q₁
= 4.5, median = 9 , Q₃ = 15.5 and

then, he wants to fill the tank with water until it's completely full. if he uses 85 8585 marbles, he will have to add 20.9 20.920, point, 9 liters of water. what is the volume of each marble?
a. Each marble has a volume of 0.013 liters.
b. 23.4 liters of water would be necessary if William uses 200 marbles.
a. To determine the volume of each marble, we can use the information that 85 marbles fill a tank with a volume of 20.9 liters of water:
Volume of each marble = (26 liters - 20.9 liters) / 85 marbles = 0.26 liters - 0.247 liters/marble = 0.013 liters/marble
So, each marble has a volume of 0.013 liters.
b. To determine the amount of water necessary if William uses 200 marbles, we can use the formula:
Volume of water = Total volume of tank - Volume of marbles
Volume of water = 26 liters - (200 marbles * 0.013 liters/marble) = 26 liters - 2.6 liters = 23.4 liters
So, 23.4 liters of water would be necessary if William uses 200 marbles.

Solve this trigonometric equation
Answer:
18.7 units
Step-by-step explanation:
In this right-angled triangle, you are provided with:
Two angles (i.e. 36° and 90°)
One side (i.e. Line AC, which is 11 units)
Line AB is known as the 'hypotenuse' of the right-angled triangle, which is what needs to be determined.
On the basis of 36° angle:
The side opposite (i.e. Line AC) is known as the 'opposite' or 'perpendicular side'
The side adjacent (i.e. Line BC) is known as the 'adjacent' or 'base'
Trigonometric function:
The trigonometric function, which connects an angle, it's opposite side and the hypotenuse is the 'sine function':
sinФ = [tex]\frac{opposite}{hypotenuse}[/tex]
sin36° = [tex]\frac{11}{x}[/tex]
Cross-multiplication is applied:
x needs to be isolated and made the subject of the equation:
xsin36° = 11
≡ x = [tex]\frac{11}{sin36^{o}}[/tex]
∴ x = 18.7 units (Rounded off to 3 significant figures)
The Tour de France is not a 3500 km race, it is a 3500 km cycling race. The diameter of the bike wheels used in the race must be between 55 cm and 75 cm. To find the minimum number of rotations
The minimum number of rotations required for a 3500 km race is 52,800 rotations.
This is calculated by dividing the total distance of the race, 3500 km, by the circumference of the wheel, which is 2πr, where r is the radius of the wheel. The radius of the wheel must be between 27.5 cm (half of 55 cm) and 37.5 cm (half of 75 cm). So, the minimum number of rotations is given by 3500/(23.14r), where r is the minimum radius of the wheel. Substituting in r = 27.5 cm, we get the minimum number of rotations required for a 3500 km race as 52,800.
To arrive at this result, we must first calculate the circumference of the wheel, which is given by 2πr, where r is the radius of the wheel. Since the diameter of the wheel must be between 55 cm and 75 cm, the radius of the wheel must be between 27.5 cm (half of 55 cm) and 37.5 cm (half of 75 cm).
We then divide the total distance of the race, 3500 km, by the circumference of the wheel, which is given by 2πr. Substituting in the minimum radius of the wheel, 27.5 cm, we get the minimum number of rotations required for a 3500 km race as 52,800.

Answer:
Step-by-step explanation:
Sandra, Deacon, and Breanna read a total of 5 + 6 + 7 = 18 books. Since one book was read by all three children, we need to subtract it once from the total. Therefore, they read 18 - 1 = 17 different books.
Sara needed 8 test tubes for 3 different experiments. The first experiment required 2 test tubes, leaving 8 - 2 = 6 test tubes for the other two experiments. Since the two experiments required the same number of test tubes, each one required 6/2 = 3 test tubes.
It is unclear what the question is asking. Please provide more information or a specific question.
Branson and his sister Beatrice combined their allowance of $7 each to buy a movie for $12. They spent a total of 7 x 2 = $14 on the movie. Therefore, they had 14 - 12 = $2 left to buy fruit salad. They bought 2 containers of fruit salad for $1 each, leaving them with $0. They split the containers evenly between them, so each of them got 2/2 = 1 container of fruit salad.
Before Cam broke his right arm, he could type 9 words per minute on his phone. After he broke his arm, he could only type 6 words per minute. The difference between the number of words he could type in 5 minutes before and after he broke his arm is 5 x (9 - 6) = 5 x 3 = 15 words.
Gisselle saved $6 every week for 8 weeks, so she saved a total of 6 x 8 = $48. She found a used bicycle for $50, so she did not have exactly enough for the bicycle. She was $50 - $48 = $2 short.
Write the equation of a circle whose center is at (-11,15) and whose radius is 9
Your answer must be in Standard Form AND simplified
Answer:
(x + 11)² + (y - 15)² = 81
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k ) = (- 11, 15 ) and r = 9 , then
(x - (- 11) )² + (y - 15)² = 9² , that is
(x + 11)² + (y - 15)² = 81
Manisha designed a table cloth in the shape of a square of side 54cm . She wants to decorate its boundaries by sticking a lace around it . Fing the cost of putting lace around the table cloth at the rate of ₹8.5 per meter.
So the total cost of tying the lace around the tablecloth is $18.36.
What is equation?In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10.
Here,
The length of the boundary of the square table cloth is 4 times its side length, so the length of the boundary is 4 * 54 cm = 216 cm.
To convert the length from centimeters to meters, we divide by 100:
216 cm / 100 = 2.16 meters
Finally, to find the cost of sticking the lace around the table cloth, we multiply the length of the lace by the cost per meter:
2.16 meters * ₹8.5 per meter = ₹18.36
So the cost of sticking the lace around the table cloth is ₹18.36.

∠DAE + ∠EDA = 180° (Linear pair)
⇒ ∠DAE = 180° - 35°
⇒ ∠DAE = 145°
Now we find m∠BCE
We can observe that ∠BCE and ∠DAE are opposite angles .
So, ∠BCE = ∠DAE
⇒ m∠BCE = 145°

whats the probability of suriving the second try given his survival in the first try if he doesn't spin the cylinder
It is not possible to determine the probability of survival on the second try if the cylinder is not spun, as the outcome of the first try has no bearing on the outcome of the second try if the cylinder is not spun.
The cylinder serves to randomly distribute the bullet among the chambers, so if the cylinder is not spun, the bullet will remain in the same chamber, and the outcome of the second try will be determined by the initial placement of the bullet in the cylinder.
In a typical scenario where a revolver with a single bullet is used, the probability of survival on the first try is 1/6, and the probability of survival on the second try (assuming the cylinder is spun) is also 1/6. However, without spinning the cylinder, the outcome of the second try is fixed and cannot be determined probabilistically.

8 Ones Is Equivalent To 80 Tenths. Divide 80 Tenths By 9 Ones On The Algorithm. Then Multiply And Subtract To Show How Many Tenths You Have Left.
We have 72-tenths left.
What is a Fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. When used in conversational English, a fraction indicates the number of components of a particular size, as in one-half, eight-fifths, and three-quarters.
To divide 80 tenths by 9 ones, we first convert the 9 ones to tenths. 9 ones is equivalent to 90 tenths.
Next, we divide 80 by 90:
80 / 90 = 0.8888... (rounded to four decimal places)
To multiply, we multiply 0.8888... by 9:
0.8888... * 9 = 8
Finally, to subtract, we subtract 8 from 80:
80 - 8 = 72
So, we have 72-tenths left.

To subtract two fractions, we must find a common denominator and subtract the numerators.
Solving the Question
The entire circle represents one whole.
To find the fraction for the shaded region, we must subtract [tex]\dfrac{1}{2}[/tex] and [tex]\dfrac{3}{7}[/tex] from one whole:
[tex]1-\dfrac{1}{2}-\dfrac{3}{7}[/tex]
One whole minus half the whole would leave us with just half:
[tex]\dfrac{1}{2}-\dfrac{3}{7}[/tex]
Now, to find a common denominator, multiply the numerator and denominator of each fraction by the denominator of the other fraction:
[tex]\dfrac{1*7}{2*7}-\dfrac{3*2}{7*2}\\\\= \dfrac{7}{14}-\dfrac{6}{14}[/tex]
Now, subtract normally:
[tex]\dfrac{7}{14}-\dfrac{6}{14}\\\\= \dfrac{1}{14}[/tex]
Answer[tex]\dfrac{1}{14}[/tex]
A state government gives property owners a tax rebate with the anticipation that each property owner will spend approximately p% of the rebate, and in turn each recipient of this amount will spend p% of what he or she receives, and so on. Economists refer to this exchange of money and its circulation within the economy as the “multiplier
effect.” The multiplier effect operates on the idea that the expenditures of one individual become the income of another individual. For the given tax rebate, find the total amount of spending that results, assuming that this effect continues without end.
Tax rebate: $400, p% = 75%
It should be noted that the amount based on the information will be $1600.00.

When does
expanding and simplifying a(b + c) result in
a positive value for ac?
Expanding the expression a(b + c) = ab + ac, the value of ac is positive if both a and c are positive or if both a and c are negative.
Using Basic Distributive PropertiesBy Multiplying the term outside the brackets by each term inside the brackets
Using this method you can distribute the outer terms into the inner terms. You can multiply the term outside the brackets by the first term inside the brackets. Then multiply the outside term by the second term. If there are more than two tribes, then continue to distribute the tribes until the tribe has no remainder. Keep the signs (positive or negative) in parentheses.
For example:
2(x-3) = 10
2(x) – (2)(3) = 10
2x – 6 = 10
We also know that the distribution characteristic state is a(b + c) = ab + ac.
Because plus times plus is plus and minus times minus is plus. When expanding the phrase a(b + c) = ab + ac, the value of ac is positive if both a and c are positive, and the value of ac is negative if both a and c are negative.
