HELP PLEASE!!!!!!!!

The angles of a triangle add up to 180 degrees

180 - 80 = 100

Both of the unknown angles are the same. So...

100/2= 50

X = 50 degrees

a port and a radar station are 2 mi apart on a straight shore running east and west. a ship leaves the port at noon traveling no

Rom4ik [11]

Answer:

The rate of change of the tracking angle is 0.05599 rad/sec

Step-by-step explanation:

Here the ship is traveling at 15 mi/hr north east and

Port to Radar station = 2 miles

Distance traveled by the ship in 30 minutes = 0.5 * 15 = 7.5 miles

Therefore the ship, port and radar makes a triangle with sides

2, 7.5 and x

The value of x is gotten from cosine rule as follows

x² = 2² + 7.5² - 2*2*7.5*cos(45) = 39.04

x = 6.25 miles

By sine rule we have

$\frac{sin A}{a} = \frac{sin B}{b}$

Therefore,

$\frac{sin 45}{6.25} = \frac{sin \alpha }{7.5}$

α = Angle between radar and ship α

∴ α = 58.052

Where we put

$\frac{sin 45}{6.25} = \frac{sin \alpha }{x}$ to get

$\frac{x}{6.25} = \frac{sin \alpha }{sin 45}$ and differentiate to get

$\frac{\frac{dx}{dt} }{6.25} = cos\alpha\frac{\frac{d\alpha }{dt} }{sin 45}$

$\frac{15sin45 }{6.25cos\alpha } =\frac{d\alpha }{dt} }$ = 3.208 degrees/second = 0.05599 rad/sec.

1. Determine the percent of all voters that did not vote Republican or Democrat but voted "other" instead. Round your answer to

lyudmila [28]

Answer:

1. 10%

2. 49.1%

Step-by-step explanation:

1. The percent of voters who are other is the number of other divided by the total number of voters.

The number of "other" votes is 222. The number of total votes is 2,222.

The percent is 222/2222 = 0.0999. Times the decimal by 100 for the percent.

0.0999*100 = 9.99% rounds to 10%.

2. The probability is found by finding the number of male and registered as democrat, which is 600, and dividing it by the number of males, which is 1,222.

600/1,222 = 0.4909

Multiply by the decimal by 100 to find the percent.

0.4909*100 = 49.09 which rounds to 49.1%.
