The answer to the question

Nuetrik [128]3 years ago

The meaning of the options are:

  • Acute: an angle between 0 and 90 degrees;
  • Straight: and angle of 180 degrees;
  • Right: an angle of 90 degrees
  • Obtuse: an angle of more than 90 degrees

So, AFB is acute, because it's and angle of 48 degrees, between it's complementary to BFC and they for a right angle.

DFB is obtuse, because it's the right angle DFC plus the angle CFB

Finally, CFD is right (we can only deduce this by looking at the picture)

Uma volta inteira na Terra corresponde a uma distância 2πr≅40.000 km. Se um satélite leva 85 minutos para dar uma volta completa
Shalnov [3]

Answer:

7.8. 10 ^ 3 m / s

Step-by-step explanation:

The computation of the average speed in m/s is shown below:

The average speed equation is

= ΔS ÷ Δt;

As We know that

an entire revolution would be40,000 km

and a satellite takes 85 minutes to complete a revolution,  

So,

ΔS = 40,000 km = 40,000,000 m

Δt = 85 min = 5 100 s

Now the average speed is

= 40 000 000 ÷ 5 ÷ 5 100

 = 7843.14 m / s

= 7.8. 10 ^ 3 m / s

Answer:

The answer to your question is below

Step-by-step explanation:

Number 9.

To find x use the law of sines

                   sin x / 8 = sin 95 / 12

Solve for sin x

                   sin x = 8 sin 95 / 12

                   sin x = 0.664

                        x = 41.6°

Number 10

To find x use law of cosines

                    x² = 6² + 8² - 2(6)(8)cos100

                    x² = 36 + 64 - 96(-0.174)

                    x² = 100 + 16.67

                    x² = 116.67

                   x = 10.80

When a man observed a sobriety checkpoint conducted by a police​ department, he saw 671671 drivers were screened and 77 were arr
kifflom [539]

Answer:

P(\overline W)=0.98957

Step-by-step explanation:

Number of drivers Screened = 671

Number Arrested for Driving While Intoxicating = 7

If the W denotes the event of screening a driver and getting someone who is intoxicated.

The Probability of W, P(W)=\frac{7}{671}=0.01043

  • The Probability P(\overline W) is the probability of the event of screening a driver and getting someone who is not intoxicated. Simply put, it is the Probability of the Complement of W.

From Probability Theorem,

P(W)+P(\overline W)=1\\Since \: P(W)=0.01043\\0.01043+P(\overline W)=1\\P(\overline W)=1-0.01043\\=0.98957
