Answer:

It could fly 12.6 kilometers.

Step-by-step explanation:

The European swallow fly speed is 12 meters per second.

We have to calculate how many kilometers it could fly in 15 minutes.

This can be calculated using the equivalent factors for each of the units:

- 1 km is equivalent to 1,000 meters.

- 1 minute is equivalent to 60 seconds.

ANSWER:
12.6 km

EXPLANATION:
If the swallow fly goes 14 m/s then you can multiply 14x60 to get 840m per minute.
From there you multiply 840x15 and get 12,600m for 15 minutes. You then divide 12,600/1000 to convert meters into kilometers and you get 12.6km.

Hope this helped!

Given: the triangle is a right triangle, find A .<br><br> A. 39°<br> B. 49°<br> C. 51°
IceJOKER [234]

Answer: 39 degrees

Step-by-step explanation:

Since the triangle is a right angle

The sum of angles in a right angle is 90degrees

51degrees + A= 90 degrees

A= 90degrees - 51 degrees

A=39 degrees

The weight y of a object on Jupiter is proportional to the weight x of the object on earth. An object that weighs 150 ponds on e
mario62 [17]

Answer:

5.02 pounds

Step-by-step explanation:

y = k*x

Where,

y = weight of a object on Jupiter

x = weight of the object on earth

k = constant of proportionality

An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter.

y = k*x

378.2 = k*150

378.2 = 150k

k = 378.2/150

= 2.5213

Approximately k = 2.52

determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth

y = k*x

12.64 = 2.52*x

12.64 = 2.52x

x = 12.64 / 2.52

= 5.0159

Approximately x = 5.02 pounds

Anestetic [448]

Answer:

Studying probability and statistics will allow you to see the world from an entirely different perspective, since the subjects will give you the tools to model and analyze situations, which involve uncertainty.

A parcel delivery service will deliver a package only if the length plus girth​ (distance around) does not exceed 84 inches. ​(A
Kisachek [45]

Answer:

A. 14x14x28

B. The maximum volume is 5488 cuibic inches

Step-by-step explanation:

The problem states that the box has square ends, so you can express volume with:

v=x^{2} y

Using the restriction stated in the problem to get another equation you can substitute in the one above:

4x+y=84\\\\

Substituting <em>y</em> whit this equation gives:

v=x^{2} (84-4x)\\\\v=84x^{2} -4x^{3}

Now find the limit of <em>x</em>:

\frac{84x^{2}-4x^{3}}{dx}=168x-12x^{2}\\\\x=\frac{168}{12}=14

Find the length:

y=84-4(14)=28

You can now calculate the maximum volume:

v=(14)^{2}(28)= 5488
