A) 2.025 x 10^14 kilometers / 225 million years

B) 2.25 × 10^8

C) 2.025 x 10^14 kilometers / 2.25 x 10^8 years

D) 2.025 x 2.25 = .9

E) 10^14 - 8 = 10^6

F) .9 x 10^6

Notes:
To write in scientific notation, move the decimal place over until there is only 1 number outside of it. (25,000 now equals 2.5) Then count how many spaces you moved over (25,000 moved over three zeros, and the five. That is 4 places) that is what you use to put over the 10 (2.5 x 10^4 = 25,000)

The longer leg of a 30,-60,-90 degree triangle is 18: what is the length of the other leg
taurus [48]

Answer:

The other legs are 9 and 9√3

Step-by-step explanation:

The longer side of a 30-60-90 degree rectangle is 18.

The other legs will be

\frac{x}{2}

and

\frac{x}{2}  \sqrt{3}

Where x is the longest side, which is given as 18.

Therefore one leg will be:

\frac{18}{2}  = 9

and the other leg will be:

\frac{18}{2}  \sqrt{3}  = 9 \sqrt{3}
