In scientific notation, you need a number from 1 to less than 10 multiplied by a power of 10.
To turn 384,400 into a number from 1 to under 10, place a decimal point after the 3.
Now you have a number from 1 to less than 10.
3.844
Now count the number of places the decimal point moved left from its original position.
The decimal point was here: 384,400. after the last zero.
The decimal point moved 5 places to the left to be placed after the 3.
Since the decimal point moved 5 places left, the exponent of the 0 is 5.
384,400 = 3.844 * 10^5

The answer is A
Step-by-step explanation:
The rectangular has a height of 4 unit and has a width of 7 units. Area of the rectangular is:

28 unit square.
The point of (2,2) is on the middle height of rectangular shape. The point has 2 unit distance to base and ceiling of the rectangular.
The line y=2 is passing thought on (2,2) and also divides rectangular into two rectangular which have 14 unit square area.
Therefor, the slope is 0
Answer:

Step-by-step explanation:
In right triangles only, the tangent of an angle is equal to its opposite side divided by its adjacent side.
Therefore, we have the following equation:

Solving, we get:

Also in right triangles only, the cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle.

We can also use the Pythagorean theorem now that we've found BC. However, if you choose to do so, make sure you don't use a rounded value for BC, as that could cause a notable deviation in your final answer.
Using the Pythagorean theorem to verify our answers:

An hour is 60 minutes
there are three hours so
60*3=180
how many times will 3.5 go into 180 so
180/3.5=51.43 or rounded up you get 52 songs (if they're good, they'll play 52 average songs and one half legnth songs)
so they will need 52 songs
