On average, the moon is 384,400 kilometers from the Earth . How is this distance written in scientific notation?

GrogVix [38]

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 vertices of a rectangle in the standard (x,y) coordinate place are (0,0), (0,4), (7,0) and (7,4). If a line through (2,2) pa

Pie

Answer:

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:

$4*7=28$

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

Someone pls help, its on trig ratios.

Mars2501 [29]

Answer:

$BC=12.8,\\AC=15.1$

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:

$\tan 58^{\circ}=\frac{BC}{8}$

Solving, we get:

$BC=8\tan 58^{\circ}\approx \boxed{12.8}$

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

$\cos 58^{\circ}=\frac{8}{AC},\\AC=\frac{8}{\cos 58^{\circ}},\\AC\approx \boxed{15.1}$

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:

$8^2+(8\tan 58^{\circ})^2=\left(\frac{8}{\cos 58^{\circ}}\right)^2\:\checkmark$

For the Christmas dance ,the dance committee needs three hours of music. Each song is an average of 3.5 minutes . how many song

GREYUIT [131]

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
