Answer:

. A blimp is flying directly above a football field. The angle of depression. 555.OF+ to the base of one goal post is 40. The angle of depression to the base of the other goal post is 72". If the goal posts are 360 feet apart. 7. how high is the blimp flying? Round to the nearest tenth of a foot. : a Sih C 8 360 5in (68) 333.8 36 0F 7. The bearing from a lighthouse to Ship A is S71 E. The bearing from the lighthouse to Ship B is S 39° E. If Ship A is 15 kilometers from the lighthouse and Ship B is 96 kilometers from the lighthouse, find the distance between the ships. Find the areg of each triangle. Round answers to the nearest tenth. B. 84.0 8. 2. 11m ((uSin 64) 15.q ft 64 10.

The blimp flying is "237 m" high.

According to the question,

In ΔABC,

∠XCA = ∠CAB = 72°

∠YCB = ∠CBA = 40°

Now,

→ ∠A + ∠B + ∠C = 180°

By putting the values,

  72° + 40° + ∠C = 180°

           112° + ∠C = 180°        

                     ∠C = 180° - 112°

                           = 68°

By applying Sin Rule,

→ [tex]\frac{AB}{Sin \ 68^{\circ}} = \frac{AC}{Sin \ 40^{\circ}}[/tex]

        AC = [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex]

We know that,

Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° ...(Equation 1)

Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × h ...(Equation 2)    

From "Equation 1 and 2",

→ [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° = [tex]\frac{1}{2}[/tex] × AB × h      

                                   h = AC × Sin 72°

By substituting value of "AC",

                                      = [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex] × Sin 72°

                                      = 237.36 or, 273 m

Thus the answer above is correct.

Answer: C. [tex]\sqrt[3]{5}[/tex]

Step-by-step explanation: Plato/ Edmentum

The simplified form of square root 45 is 3√5. Therefore, the correct answer is option C.

The given number is √45.

The square root of a number is the inverse operation of squaring a number. The square of a number is the value that is obtained when we multiply the number by itself, while the square root of a number is obtained by finding a number that when squared gives the original number.

Here, factors of 45 = 3×3×5

√45 = √3×3×5

= 3√5

Therefore, the correct answer is option C.

Answer:

Number of bicycles = 30

Number of skateboards = 12

Step-by-step explanation:

Let the number of bicycles = x

Let number of skateboards = y

It is given that there are total bicycles and skateboards = 42

∴ x + y = 42  ........(1)

Now a bicycle has two tires and a skateboard has four tires, this gives an equation :

2x + 4y = 108 .......(2)   (Since uncle Eddie asks to order 108 tires)

Therefore, solving equation (1) and (2), we get

2(x+y=42)

2x+4y=108

  2x+2y = 84

- (2x+4y = 108)  

      - 4 y = - 24

    or   4 y = 24

   or      y = 12

Now substituting the value of y in equation (1),

x + 12 = 42

x = 42 -12

x = 30

So number of bicycles = x =30

And number of skateboards = y = 12

Answer:

C.) The perimeter is doubled and the area is quadrupled.

Step-by-step explanation:

Original square: side = 4

Area = side^2 = 4^2 = 16 square units

Perimeter = 4 * side = 4 * 4 = 16 units

Larger square: side = 8

Area = side^2 = 8^2 = 64 square units

Perimeter = 4 * side = 4 * 8 = 32 units

Comparison of areas:

(larger square area)/(original square area) = 64/16 = 4

Comparison of perimeters:

(larger square perimeter)/(original square perimeter) = 32/16 = 2

Answer:

C.) The perimeter is doubled and the area is quadrupled.

There are a number of reasons why some students decide not to go to school. Some of them may be associated with family and psychological problems such as anxiety and depression, which should be investigated by trained professionals at the school if there is any suspicion of these symptoms.

There is also the possibility that students who have decided not to go to school have been victims of bullying and aggression at school, which causes fear of retaliation and psychological trauma that negatively impact the person's life.

It is important that schools provide psychological support and an active policy that combats bullying and is pro-integration of students and diversity.

Answer:

169.23m

Step-by-step explanation:.

Let's calculate the base of the cliff. Using SOH CAH TOA identity

Height (opposite) = 142n

Angle of depression = 40°

Required

Base of the cliff

Tan theta = opposite/adjacent

Tan 40 = 142/x

x = 142/tan40

x = 142/0.8391

x = 169.23m

Hence the base of the cliff is 169.23m long
