A satellite can move at 17,000 miles per hour. how many hours will it take to reach a star that is three light years away? recal

Feliz [49]

Distance to the star in light years = 3 * 0.62 * 9.5 * 10^12 = 1.767 * 10^13 miles

dividng this by 17,000 gives 1.039411765 * 10^9 hours

Math help? Easy but I can't get it! :(

Vladimir79 [104]

Ok, so, the question states that the distance driven is proportional to the time driven in hours. So, the x value would be hours driven, while the y-value would be the number of miles driven. So, in order to find the speed at which she is driving, you will want to divide the number of miles by the number of hours driving, or 180/3, You answer should be 60, or 60 mph is her speed.

when a number is written in scientific notation how can you tell right away weather or not it is greater than or equal to one

lidiya [134]

Right away, you can tell that the number is greater that one if the exponent is positive. For example, 1.23 x 10 to the power of 2 would be 123, which is greater than 1. If the exponent is negative, the answer will most likely be less than 1. For example, 1.23 to the power or -2 would be .0123.

Hope this helps!

Answer:

A. The area is $78.54m^2$

B. She needs to cover 1661.9 square feet of tiles for the base of the swimming pool

Step-by-step explanation:

Question A:

Let us assume that the leash is pegged to the ground using a stake. as a result, the dog can move around the stake. The path that the motion of the dog would trace is a circle, and the radius of the circle will be the length of the leash.

Since we know this, we can easily find the area of the circle using $\pi r^2$

Area of the circle = $\pi \times 5 \times 5 = 78.54m^2$

Question B

Dulce wants to cover the whole surface area of the floor of the circular swimming pool with tiles.

We already know that the swimming pool is circular, hence, the surface area of the base of the swimming pool will be the same as the area of a circle, with the same radius.

The area of the circle can be calculated using $\pi r^2$

Area of circle = $\pi \times 23 \times 23 = 1661.9ft^2$
