grin007 [14]

Given:

A rope tied from a tent pole to a stake in the ground forms 55 degrees angle with the ground.

The pole is 3 feet from the stake.

To find:

The length of the rope to the nearest tenth of a foot.

Solution:

First draw a diagram according to the given information as shown below.

We know that, in a right angled triangle,

$\cos \theta = \dfrac{Base}{Hypotenuse}$

In triangle ABC,

$\cos 55^\circ=\dfrac{BC}{AC}$

$0.573576=\dfrac{3}{AC}$

$AC=\dfrac{3}{0.573576}$

$AC=5.23034$

$AC\approx 5.2$

Therefore, the length of the rope is 5.2 foot.

Eduardwww [97]

So first we need to know this:

Two negative signs make a positive
Two positives make a positive
One positive and one negative makes a negative.

So we can turn the equation to -4 -44 - - 1
2 minuses make plus
-4 -44 +1 = -48 +1 = -47

never [62]

Answer: The blue whale's weight is 150 times heavier than the narwhal's weight.

Step-by-step explanation:

Given: Weight of Blue whale = $3\times10^5\text{ pounds}$

Weight of Narwhal = $2\times10^3\text{ pounds}$

Number of times blue whale's weight is heavier than the narwhal's weight = $=\dfrac{\text{Weight of Blue whale}}{\text{Weight of Narwhal }}$

$=\dfrac{3\times10^5}{2\times10^3}\\\\=1.5\times10^{5-3}\ \ \ [\dfrac{a^m}{a^n}=a^{m-n}]\\\\=1.5\times10^2\\\\=1.5\times100=150$

Hence, the blue whale's weight is 150 times heavier than the narwhal's weight.
