Answer:

Both trucks are 150 miles after 1.516 hours

Solution:

Given, Two trucks leave a factory at the same time.

one travels east 60 miles per hour, and the other travels west at the 39 miles per hour.

We have to find In how many hours will they be 150 miles apart?

Let the time after which they will be 150 miles apart be t.

Now, we know that, distance = speed x time. 

For 1st truck ⇒ distance from factory = 60 x t

For 2nd truck ⇒ distance from factory = 39 x t

Here, t is same for both trucks as time is seen from common point of view.

Now, according to the given information,

distance of 1st truck from factory + distance of 2nd truck from factory = 150 miles.

60t + 39t = 150

99t = 150

t = 1.516 approximately.

Hence, both trucks are 150 miles after 1.516 hours.

A circular mirror has a diameter of 12 inches what is the are in square inches of the mirror?

pochemuha

The area of a circle is (pi) x (the circle's radius)²

The circle's radius is (1/2) of (its diameter).

Area = (pi) x (12/2 inches)² =

(pi) x (6 inches)² =

(3.14) x (36 square inches) = 113 square inches (rounded)

Please help! Geometry.

These are right triangles that will use either sin, cos, or tan, depending upon what you have to work with in regards to the reference angle. The first one has a reference angle of 51 with y being the side opposite it and 12 being the hypotenuse. The sin identity uses the side opposite over the hypotenuse as its formula:
$sin(51)= \frac{y}{12}$
and 12 sin(51) = y and y = 9.325
The second one has the reference angle as the unknown. You could use any of the identities here because you have all the sides of the triangle, but I will use sin again:
$sin \beta = \frac{12}{13}$
and $sin \beta =.9230769$
and $sin ^{-1}(.9230769)=67.38$
The next one has a referece angle of 13 with 24 being the side adjacent to it and the unknown being the side across from it. You will use the tangent identity here:
$tan(13)= \frac{x}{24}$
and 24 tan(13) = x so x = 5.540
The last one has a reference angle of 20 with the hypotenuse as the unknown x, and the side across from it as 10. Use the sin identity again:
$sin(20)= \frac{10}{x}$ and
$x sin(20)=10$ and
$x= \frac{10}{sin(20)}$ with x = 29.238
Everything is in regards to the reference angle; you HAVE to be able to identify the reference angle and then how the given sides are related to it.
