The height of the kite is 38.042(approx.) and the shadow of kite from Dmitri is 12.36 m (approx.)
What is angle of elevation?The term angle of elevation denotes the angle from the horizontal upward to an object. An observer’s line of sight would be above the horizontal.
According to the question
Kite string = hypotenuse = 40m
angle of elevation = 72 °
a) Height of kite = perpendicular
sin( 72 °) = [tex]\frac{Perpendicular}{hypotenuse}[/tex]
0.951 = [tex]\frac{Perpendicular}{40}[/tex]
38.042 ≈ Perpendicular or Height of kite ≈ 38.042
b) Sun is directly above the kite , kite's shadow from Dmitri is = base
Tan (72°) = [tex]\frac{perpendicular }{base}[/tex]
3.077 = [tex]\frac{38.042 }{base}[/tex]
Base ≈ 12.36 m
Hence, height of the kite is 38.042(approx.) and the shadow of kite from Dmitri is 12.36 m

The spinner game at the school carnival has a long line, but Edgar thinks that the fun prizes are worth the wait. The spinner is divided into 4 unequal sections. As he moves up in line, Edgar notices the spinner results of the people ahead of him: 3 glow sticks, 5 bouncy balls, 8 whistles, and 2 foam gliders
The probability of the spinner landing on whistle during Edgar's turn is 4/9
How to determine the probability?The experimental results are given as:
3 glow sticks, 5 bouncy balls, 8 whistles, and 2 foam gliders
The total number of sample is:
Sample = 3 + 5 + 8 + 2
Sample = 18
The probability that Edgar's spin land on whistle is:
P(Whistle) = Whistle/Sample
This gives
P(Whistle) = 8/18
Evaluate
P(Whistle) = 4/9
Hence, the probability of the spinner landing on whistle during Edgar's turn is 4/9

If a teacher gives a quiz that is normally distributed and has a mean score 50 and a standard deviation of 5:
a) what z score is associated with a 60th percentile
b) what score is associated with the 60th percentile
Using the normal distribution, it is found that:
a) The z-score associated with a 60th percentile score is of Z = 0.253.
b) The score associated with the 60th percentile is of 51.265.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 50, \sigma = 5[/tex]
The 60th percentile is X when Z has a p-value of 0.6, so X when Z = 0.253, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.253 = \frac{X - 50}{5}[/tex]
X - 50 = 5(0.253)
X = 51.265.

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. Sho
Answer:
Top Left (<A) = 86 degrees // Top Right (<B) = 112 degrees // Bottom Left (<C) = 68 degrees // Bottom Right (<D) = 94 degrees
Step-by-step explanation:
So with inscribed quadrilaterals opposing corners are supplementery. This means they will add to 180 degrees. So first what we can do is set (x + 2) and (x - 6) equal to 180 ----> 2x - 4 = 180 ----> 2x = 184 ----> x = 92
So if x = 92 then <A = 86 degrees //// <B = 112 degrees //// <C must equal 68 degrees because <B and <C are supplementery //// <D = 94 degrees

If y varies jointly with x and z, and y = 200 when x = 8 and z = 10, what is x when y = 165 and z = 11? what is the value of k? 250 160 5.2 2.5
The value of x is 6 and the value of k is 2.5. The correct option is the last option - 2.5
VariationFrom the question, we are to determine the value of k, that is, the constant of proportionality
From the given information,
y varies jointly with x and z
Mathematically, this can be written as
y ∝ xz
Then, introducing the constant of proportionality, k, we get
y = kxz
Also, from the given information
y = 200 when x = 8 and z = 10
Putting these values into the equation, we get
200 = k × 8 × 10
200 = 80k
∴ k = 200/80
k = 2.5
Now, for the value of x when y = 165 and z = 11
Using the equation
y = kxz
Then, put the parameters into the equation
165 = 2.5 × x × 11
165 = 27.5x
∴ x = 165 / 27.5
x = 6
Hence, the value of x is 6 and the value of k is 2.5. The correct option is the last option - 2.5

Answer:
Q = 108°
R = 72°
Step-by-step explanation:
Quadrilateral means this is a four-sided shape. Parallelogram means that both sets of opposite side are parallel, so all the angles are either equal or add up to 180° (supplementary)
The order of the letters matters bc PQRS means that you go along an edge from P to Q, but you have to go thru the middle of the shape to get from P to R. So P and Q add up to 180°.
P + Q = 180°
72° + Q = 180°
Q = 108°
Opposite from each other, across the middle of the shape, P and R are equal.
P = R = 72°

find the area of sector =?
Step-by-step explanation:
270°/360° ×π×13²cm
=398.20cm²
the area of the sector with a radius of 13 units and a central angle of 270 degrees is approximately 398.25 square units.
To find the area of a sector, we use the formula:
Area of sector = (θ/360) * π * r²
Where:
θ is the central angle of the sector in degrees,
r is the radius of the sector.
In this case, the radius (r) is 13 units, and the central angle (θ) is 270 degrees.
Area of sector = (270/360) * π * 13²
Area of sector = (3/4) * π * 169
Area of sector = (3/4) * 169π
Area of sector ≈ 398.25 square units
So, the area of the sector with a radius of 13 units and a central angle of 270 degrees is approximately 398.25 square units.

Find the number of sample outcomes that are common to the two events.
Answer:
The event space is the number of outcomes in the event you are interested in. The event space for rolling a number less than three is 1 or 2. So the size of the event space is 2. For equally likely outcomes, the probability of an event E can be written P(E).
The number of sample outcomes that are common to the two events would depend on the specific events and the information provided about their sample spaces.
To find the number of sample outcomes that are common to two events, we need to determine the intersection of the two events. The intersection represents the outcomes that satisfy both events simultaneously.
If we know the number of sample outcomes for each individual event, we can find the number of outcomes that are common to both events by finding the smaller of the two numbers.
For example, let's say event A has 50 possible outcomes and event B has 30 possible outcomes. The number of sample outcomes that are common to both events would be the smaller of the two, which is 30 in this case.
Therefore, the number of sample outcomes that are common to the two events would depend on the specific events and the information provided about their sample spaces.

Answer:
C
Step-by-step explanation:
because 14 is 7 x 2 the scale factor from the small pyramid to the big pyramid would be 1/2
Answer:
(b) 1/8
Step-by-step explanation:
You want the ratio of the volume of the small pyramid to that of the larger one, given their base lengths are 7 and 14 units.
Scale factorThe pyramids are presumed to be similar, so the ratio of the sides given is also the ratio of the unmarked sides and the heights. The volume ratio is the cube of this ratio of side lengths:
smaller/larger sides = 7/14 = 1/2
smaller/larger volumes = (1/2)³ = 1/8
The ratio of the volume of the small pyramid to the larger is 1/8.
