skelet666 [1.2K]

Answer:

The second and the last options.

Step-by-step explanation:

15/ 2/9 =67.5 Solve the original problem

15*2/9 =3.33333333333

15*9/2 =67.5

(15* 1/9) /2=0.833333333333333

Bezzdna [24]

Using the given information and what we know about linear equations, we will find the sketch below.

<h3>How to sketch a graph?</h3>

Here we need to analyze each part separately.

In a coordinate axis where the y-axis represents distance and the x-axis represents time, we will have that:

First, we know that he rides for 30 minutes at a given speed, this will be represented with an increasing linear function.

Then he stops for 20 minutes, this is represented with a horizontal line.

Finally, he returns the motion, but slower than before, so the slope of this line will be smaller than the first one.

So for 0 to 30 we have an increasing linear equation, then for 30 to 50 we have a constant horizontal line, then for 50 to 80 we have another increasing linear equation

The sketch can be seen below.

Andreas93 [3]

Answer:

s=30f

Step-by-step explanation:

S = second; F = flying time.

Since it can flap its wings 30 times, each second, we have already found our answer. The relationship between flying time (Wing flaps) and seconds is 30. In other words, it beats it's wings 30 times each second. Which is what the question asks.

Now we just have to write the equation:

s=30f

This is because the seconds are <u>dependent</u> on the flap of wings, so s would be the y value.

Hope it Helps!
