An albatross can fly 400 kilometers in 8 hours at a constant speed using d as distance and t as number of hours. An equation tha
kow [346]

Answer:

Constant of Proportionality is 50.  

Step-by-step explanation:

Albatross can fly 400 kilometers in 8 hours.

'd' represents the distance and 't' represents the number of hours.

The equation d=50t represents the relationship between the distance and time.

Now, in the equation shown above 50 is the constant of proportionality, and 50 represents the rate of change of distance with time.

The constant of proportionality tells us the rate of change between two variables.

So for every 1 hour of time the distance covered is 50 kilometers.

Veronika [31]

Answer:

Length: 11.95

Width: 9.95

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

To begin solving this question we need to create a formula to then solve. According to the information given in the question we can create 2 formulas.

P = 2L+2W

L = 2+W

<u>Where:</u>

  • P is the perimeter
  • L is the length
  • W is the width

Now we can replace L for the L in the P formula and solve for W, Like so....

43.8 = 2(2+W)+2W

43.8 = 4+2W+2W

39.8 = 4W

9.95 = W

Now that we have the value of W we can plug that into the L formula and find L

L = 2+9.95

L = 11.95

Finally, we can see that the value of the Length is 11.95 in and the Width is 9.95 in

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
