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=34

Step-by-step explanation:

Use the Pythagorean theorem [tex]a^{2} +b^{2} =c^{2}[/tex]

(16^2)+(30^2)=c^2

1156=c^2

[tex]\sqrt{1156}[/tex]=c

The total number of turtles born is 40,000.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, only 3% of turtle hatchlings will live to become breeding adults.

The current number of breeding adults is 1,200

Let the total number of turtles born be t.

Now, 3% of t=1200

3/100 ×t=1200

3t=120000

t=40000

Therefore, the total number of turtles born is 40,000.

Step-by-step explanation:

Height of triangle (h) = 2.5 + 4 = 6. 5 cm

Base of triangle (b) = 3 + 3 = 6 cm

Radius of circle (r) = 4 cm

Required probability = Area of triangle/Area of circle

[tex] = \frac{ \frac{1}{2} bh }{\pi {r}^{2} } \\ \\ = \frac{ \frac{1}{2} \times 6 \times 6.5 }{3.14 \times {4}^{2} } \\ \\ = \frac{3 \times 6.5}{3.14 \times 16} \\ \\ = \frac{19.5}{50.24} \\ \\ = 0.388136943 \\ \\ \approx0.39[/tex]

. 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.

Step-by-step explanation:

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:

Step-by-step explanation:

6x^2+4xy

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.

Step-by-step explanation:

16x+16x+13x= 180

45x= 180

x= 4

16x= 64°

16x = 64°

13x= 52°

Answer:

45 degrees

Step-by-step explanation:

Using the pythagorean theorem, the 3rd side=19. So the triangle is isosceles and therefore the 2 angles we don't know the measure of are congruent. One angle measures 90 degrees. So the last 2 angles must be 90 together, since we know a triangle equals 180 degrees. Therefore the angle we are trying to find is 45 degrees.
