When a value is given in scientific notation, how can you tell if the number is very large or very small? explain.

The exponent indicates how large or small the number is. A positive exponent moves the decimal to the right, which creates a very large number. On the other hand, a negative exponent moves the decimal to the left, which creates a very small number.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
