i would say this is a observational study. just because they arent giving specifics on how much water, so i dont think it would be experimental.

Help?

Pachacha [2.7K]

Answer:

The correct option is: 32.4 km/h

Step-by-step explanation:

The fastest recorded speed of a turtle while swimming is 9 m/s.

Now, 9 m/s $=\frac{(9)meters}{(1)second}$

1 kilometer= 1000 meter

So, 1 meter $= \frac{1}{1000}=0.001$ kilometer

and 9 meters $=(9*0.001)kilometer = 0.009$ kilometer

Now, 1 hour = 3600 seconds

So, 1 second $=\frac{1}{3600}hour$

Thus, we will get.........

$\frac{(9)meters}{(1)second}=(\frac{0.009}{\frac{1}{3600}}) kilometer/hour =(0.009*3600)=32.4 km/h$

So, the speed of the turtle will be 32.4 km/h.

Mark stated that the slope of the line that passes through these two points (1, -19) and (-2, -7) is -¼. Is Mark correct? Explai

ladessa [460]

Answer:

Step-by-step explanation:

The slope formula is ...

m = (y2 -y1)/(x2 -x1)

We can use the values ...

(x1, y1) = (1, -19)

(x2, y2) = (-2, -7)

Putting these into the formula gives ...

m = (-7 -(-19))/(-2 -1) = 12/-3 = -4

The slope is -4, not -1/4. Mark is incorrect.
