The gdp of brazil in 2008 was roughly 1.6 trillion, how do you write this in scientific notation

Step-by-step explanation:

As we know a trillion has 12 zeros so GDP of Brazil which is roughly 1.6 trillion can be written as 1.6×1000000000000

A scientific notation of any number is in the form of

Now this number can be written as which is a scientific notation of 1.6 trillion.

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
