Answer:

<em>≈ 63.30 ft²</em>

Step-by-step explanation:

<em>Heron formula</em>

<em>A = √p(p - a)(p - b)(p - c)</em>

<em>a = 9 ; b = 15 ; c = 20</em>

<em>p = (a + b + c)/2 = (9 + 15 + 20)/2 = 44/2 = 22</em>

<em>A = √22(22-9)(22-15)(22-20)</em>

<em>= √22×13×7×2</em>

<em>= √4004</em>

<em>≈ 63,27</em>

<em>≈ 63.30 ft²</em>

As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second. Convert this speed to kilometers

Ira Lisetskai [31]

Answer:

The kilometers Jupiter travel in 5 seconds is <u>64 kilometers</u>.

Step-by-step explanation:

Given:

As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second.

1 mile is equal to 1.6 kilometers.

Now, to convert this speed to kilometers per second, and at this speed to find kilometers will Jupiter travel in 5 seconds.

So, to convert speed of miles per second into kilometres per second:

<em>1 mile = 1.6 kilometres.</em>

Thus, 8 miles = 8 × 1.6 = 12.8 kilometres per second.

Now, at this speed we calculate the kilometres Jupiter travel in 5 seconds by multiplying:

<em>In 1 second Jupiter travel = 12.8 kilometres.</em>

So, in 5 seconds Jupiter travel $=12.8\times 5$

$=64\ kilometers.$

Therefore, the kilometers Jupiter travel in 5 seconds is 64 kilometers.
