An albatross is a large bird that can fly 400 kilometers in 8 hours at a constant speed. Using d for distance in kilometers and

t for number of hours, an equation that represents this situation is d=50t. What are two constants of proportionality for the relationship between distance in kilometers and number of hours? 50 1/50

Answer: Two constants of proportionality for this situation are 50 and 1/50. The relationship between these two values are that they are both reciprocals.

Answer:

<h3>50</h3>

Step-by-step explanation:

Speed is represented according to the equation;

Speed = Distance/Time

Given;

Distance d = 400km

Time t = 8 hours

From the formula

s = d/t

s = 400/8

s = 50

Substitute s = 50 back into the formula;

s = d/t

50 = d/t

d = 50t

This expression means that the speed is directly proportional to t where 50 is the constant of proportionality;

Hence the constant of proportionality for the relationship between distance in kilometers and number of hours is 50

Answer:

  1100

  2200

Step-by-step explanation:

Since speed is constant, the distance is proportional to the time. We notice that the number in the second column is 1650/3 = 550 times the number in the first column, so the two missing numbers are ...

  2 × 550 = 1100

  4 × 550 = 2200

What is the area of the figure?
statuscvo [17]

Answer:

88

Step-by-step explanation:

We can divide this into 3 shapes, a square, rectangle, and triangle.

Let's solve the area of each of these shapes and add them all up.

First, let's solve the square.

We know that one side is 4 ft so that means that the other side is also 4ft.

4*4=16

Our area of the square is 16ft^2

Let's solve the rectangle next,

Its length is 12ft and its width is 4ft.

12*4=48

So the rectangle area is 48ft^2

Now for the triangle

Remember that area of a triangle is a=hb/2

Our height is 12 ft and our base is 4ft

12*4=48

48/2=24

Triangle is 24ft^2

That means that we can add them all up

24+48+16=88

88ft^2 or 88

. Mr. Donut wants to paint a donut on the wall of his restaurant. The diameter of the outside edge of the donut will be 22 inche
KATRIN_1 [288]

Answer:

The area needed to be painted is approximately 301.44 square inches.

Step-by-step explanation:

The shape of a donut is represented by two concentrical circles, whose area is described by the following formula:

A =A_{g}-A_{s} (Eq. 1)

Where:

A - Total area of the donut, measured in squared inches.

A_{g} - Area of the greater circle, measured in square inches.

A_{l} - Area of the lesser circle, measured in square inches.

By using the definition of the area of the circle, we expand the equation above:

A = \frac{\pi}{4}\cdot D^{2}_{ext} - A_{s} (Eq. 1b)

If we know that \pi = 3.14, D_{ext} = 22\,in and A_{s} = 78.5\,in^{2}, the area needed to be painted is:

A = \frac{(3.14)\cdot (22\,in)^{2}}{4}-78.5\,in^{2}

A \approx 301.44\,in^{2}

The area needed to be painted is approximately 301.44 square inches.
