An airplane is traveling at a speed of 200 km/h. Identify the correct conversion factor setup required to compute the speed of the airplane in m/s.

Answers

Answer 1

Answer:

Answer:

Speed = 55.56 m/s

Step-by-step explanation:

Given:

An airplane is travelling at the speed of 200 km/h.

We need to convert this in meter/second.

1 km = 1000 meters

1 hour = 3600 seconds

Speed = Distance/Time

Speed = (200*1000)/(1*3600)

= 200000/3600 meter/second

Speed = 55.56 m/s

Hope this will helpful.

Thank you.

The pay, P, at a certain job is calculated by the formula P=Bh, where B is the base pay an h is the number of hours worked. If an employee works more than40 hours in a week, the formula changes to P=40B+1.5B(h-40). If Susan had a base pay of $6.35 and worked 28 hours, what would be his pay for the week?

Answers

If you would like to know the Susan's pay for the week, you can calculate this using the following steps:

P = B * h
P ... the pay
B ... the base pay
h ... the number of hours worked

B = $6.35
h = 28 hours
P = B * h = $6.35 * 28 hours = $177.8

Susan's pay for the week would be $177.8.

Find the coordinates of a point on a circle with radius 5 corresponding to an angle of 25°. (x, y) = Round your answers to three decimal places.

Answers

Step-by-step explanation:

that means it is the top vertex of the inscribed trigonometric triangle.

we assume the center of the circle is at the origin (0, 0).

so, the x-coordinate is then

cos(25°)×5 = 4.531538935... ≈ 4.532

the y-coordinate is then

sin(25°)×5 = 2.113091309... ≈ 2.113

remember, the basic trigonometric functions deliver these lengths inside the norm circle (radius = 1). for any other circle we need to multiply them by the actual radius.

the point on the circle at 25° is at

(4.532, 2.113)

Solve the equation . (-2 1/7)p=-3

Answers

Answer:

p = $(7)/(5)$

Step-by-step explanation:

change the mixed number to an improper fraction

- 2 $(1)/(7)$ = - $(15)/(7)$ , hence

- $(15)/(7)$ p = - 3 ( multiply both sides by 7 )

- 15p = - 21 ( divide both sides by - 15 )

p = $(-21)/(-15)$ = $(7)/(5)$

Final answer:

To solve this question, convert '-2 1/7' to an improper fraction (-15/7), then divide both sides of the equation by this value. This simplifies to p = 1.4 which is the solution.

Explanation:

In order to solve the equation (-2 1/7)p=-3, it's helpful to remember that multiplying each side of an equation by the same value does not change the solution. In this case, (-2 1/7) represents a fraction (-15/7) when converted to an improper fraction. Now, to isolate p on one side of the equation, divide both sides of the equation by (-15/7). This provides the solution: p = -3 / (-15/7), which simplifies to p = 1.4. Therefore, the solution to the equation is p = 1.4
