Answer:

1 hen

Step-by-step explanation:

For this problem, we will simply make the assumption that 1 hen can lay 1 egg every 3 days. Using this, let's build a proportion:

1 hen / 1 egg / 3 days == x hens / 3 eggs / 9 days

Notice our rate ( 1 egg / 3 days ) remains constant. This we can conclude based on our assumption that there is only 1 hen laying eggs.

If our rate was different, then we would have additional hens proportional to the rate.

Cheers.

. A triangle has side lengths of 8, 7, and 14. To the nearest tenth of a degree find the measure of the angle opposite the side

4vir4ik [10]

Given:

The measure of three sides of a triangle are 8, 7 and 14.

To find:

The measure of the angle opposite the side of length 8.

Solution:

According to the Law of Cosine:

$\cos A=\dfrac{b^2+c^2-a^2}{2bc}$

Let a=8, b=7 and c=14, then by using Law of Cosine, we get

$\cos A=\dfrac{7^2+14^2-8^2}{2(7)(14)}$

$\cos A=\dfrac{49+196-64}{196}$

$\cos A=\dfrac{181}{196}$

Taking cos inverse on both sides.

$A=\cos^{-1}\dfrac{181}{196}$

$A=22.561328$

$A\approx 22.6$

Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.
