In the opening scene of the movie Raiders of the Lost Ark, Indiana Jones replaces a golden statue with a bag of sand. The platfo

Answer:

1920π

Step-by-step explanation:

First, you need to find the volume of the statue in terms of pi.

Volume of cylinder formula:

V=πr²h

V=π4²15

V=π16×15

V=240π

Then, you need to find the mass of the statue.

Mass:

Mass= density × volume

Mass=20×240π

Mass=4800π

Now, you need to find the volume. Since the sand has to weigh the same as the statue, the mass is going to stay the same. To find the volume you need to do:

V=mass of sand/density

V=4800π/2.5

That gives you your answer:

1920π

Note: I had to do the exact same problem on Khan Academy. This is right.

Answer:

The bird will have traveled 403 meters in 13 seconds if it maintained a speed of 31 m/sec

Explanation:

The equation that relates velocity, distance and time is:

$velocity = \frac{distance}{time}$

This means that:

distance = velocity * time

In the given, we have:

velocity = 31 m/sec

time = 13 sec

Substitute with the givens in the above equation and solve for the distance as follows:

distance = velocity * time

distance = 31 * 13

distance = 403 meters

Hope this helps :)

Answer:

43. $= \frac{.0045}{100}$

44. $4\frac{9}{10}$

45. 8

Step-by-step explanation:

43. 0.45% = .0045

$= \frac{.0045}{100}$

44. $\frac{1}{2}$ • $9\frac{4}{5}$

= $4\frac{9}{10}$

45. VIII = 8
