Answer:

  42.0°

Step-by-step explanation:

To compute the angle, we need the measures in compatible units. It can be convenient to convert feet to meters.

  Tan = Opposite/Adjacent

  tan(angle of elevation) = (building height)/(shadow length)

  angle of elevation = arctan((62 ft)(0.3048 m/ft)/21 m) = arctan(18.8976/21)

  angle of elevation ≈ 41.984°

The angle of elevation of the sun is about 42.0°.

Step-by-step explanation:

find area of square = 6 x 6 = 36

find area of one triangle = 1/2(6)(12) = 3(12) = 36

There are 4 congruent triangles, so 36 x 4 = 144

36 + 144 = 180

Answer:-x+5

Step-by-step explanation:

Answer:

k = 24, y = 24x

Step-by-step explanation:

Given x and y are proportional then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition when y = 72, x = 3 , then

72 = 3k ( divide both sides by 3 )

k = 24

y = 24x ← equation of proportion

Answer:D

Step-by-step explanation:

Neither data set has suspected outliers response best describes outliers in the data sets.

Option A is correct.

The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), ​first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

According to question

Reading:

Median = [tex]\frac{7+12}{2}[/tex] = 9.5

[tex]Q_{1}[/tex] = 5 × 25% + 7 × 75% = 6.5

[tex]Q_{3}[/tex] = 14 × 25% + 12 × 75% = 12.5

IQR is the difference between Q3 and Q1

IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 12.5 - 6.5 = 6

[tex]Q_{1}[/tex] - 1.5 IQR = 6.5 - 1.5 × 6 = -2.5 < Min = 5

[tex]Q_{3}[/tex] + 1.5 IQR = 6.5 + 1.5 × 6 = 15.5 > Max = 15

So no outlier in reading

Video :

[tex]Q_{1}[/tex] = 7 × 75% + 4 × 25% = 6.25

[tex]Q_{3}[/tex] = 21 × 25% + 18 × 75% = 18.75

IQR is the difference between Q3 and Q1.

IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 18.75 - 6.25 = 12.5

[tex]Q_{1}[/tex] - 1.5 IQR = 6.25 - 1.5 × 12.5 = -12.5 < Min = 1

[tex]Q_{3}[/tex] + 1.5 IQR  = 18.75 + 1.5 × 12.5 = 37.5 > Max = 26

So no outlier in video

So neither data set has suspected outliers.

Option A is correct.

Answer:

4.7, 5.1 and 7.4

Step-by-step explanation:

Given

[tex]t \le 7.4[/tex]

Required

Select numbers part of the solution

O  4.7    O 5.1      O 7.4      O 8.2     O 9.6​

[tex]t \le 7.4[/tex] implies that, the value of t cannot exceed 7.4.

So, we have:

4.7, 5.1 and 7.4 in this range

However, 8,2 and 9,6 do not belong to this range

Answer:

a=180-79

a=101

c=83 (vertically opposite angles)

d=c (corresponding angles)

d=83

b=a(corresponding angles)

b=101

Answer: a=101 b=79 c=83 d=97

Step-by-step explanation:

A: angles on a straight line add up to 180° so you would take away 79° from 180° which is 101°.

B: angles on a parallel lines are always the same, you can see that 79 is at the same position as b.

C: opposite angles are always the same so it would still be 83°.

D: d is on other side as c and this would add up to 180° so as we already know that c is 83° you would have to take away 83° from 180° to get d.

Answer:

Step-by-step explanation:

Step-by-step explanation:

move the shape 1 square to the left and then move it one square up

The triangle after a translation 1 unit to the left and 1 unit up will have vertices at (2, 2), (-4, 4), and (-2, 0).

Translation is a rigid transformation that moves each point of a figure a certain distance in a specified direction. For this triangle, we will translate all its vertices 1 unit to the left and 1 unit up.

Impact on the Coordinates:

Let's consider each vertex of the triangle and apply the translation:

a) Vertex (3, 1):

After the translation, this point will move 1 unit to the left and 1 unit up. Therefore, the new coordinates will be (3 - 1, 1 + 1) = (2, 2).

b) Vertex (-3, 3):

This point will also move 1 unit to the left and 1 unit up. The updated coordinates will be (-3 - 1, 3 + 1) = (-4, 4).

c) Vertex (-1, -1):

Similarly, this point will undergo the translation, resulting in (-1 - 1, -1 + 1) = (-2, 0).

New Triangle:

Now, we have the new coordinates for the vertices after the translation:

Vertex 1: (2, 2)

Vertex 2: (-4, 4)

Vertex 3: (-2, 0)

The transformed triangle will have vertices at (2, 2), (-4, 4), and (-2, 0).
