A rope tied from a tent pole to a take in the ground forms 55 degrees angle with the ground. The pole is 3 feet from the stake,
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.

kirill [66]

Answer:

1 in 3 chance

Step-by-step explanation:

Multiples of 3: 3, 6, 9, 12

This means there are 4 multiples.

4/12 or 4 ÷ 12 = 1/3

So there is a 1 in 3 chance (33.333%) to get a multiple of 3

One of the smallest pools on the ship has about 45,000 gallons of water in it.
gtnhenbr [62]

Amount of water in the pool at the end of the day is 5457798.7 gallons

<u>Explanation:</u>

Given:

Initial amount of water in the pool = 45,000 gallons

Increase in amount = 0.75 in per minute

Time, t = 1 day

t = 24 X 60 min

t = 1440 min

So,

Increase in amount of water in 1 day = 0.75 in X 1440

                                                             = 1080 in

Volume of 1080 in of water = (1080 in)³

Volume from cubic inch to gallon = 5453298.7 gallon

Amount of water in the pool at the end of the day = 45000 + 5453298.7 gallon

                                                                                   = 5457798.7 gallon

Please help me (It's for a really important grade)
Sholpan [36]

Answer:

4/5

Step-by-step explanation:

Sin = Opposite / Hypotenuse

Note that hypotenuse = longest side

We want to find sinФ

The opposite side length of angle "Ф" has a length of 8 and the longest side or hypotenuse has a length of 10

So sinФ would equal 8/10 which can be simplified to 4/5
