In 2008, the total trade between the united states and japan was $2.04 x 101^1. the total trade between the u. s. and australia was $3.28 x 10^10. how many times greater was the trade with japan than the trade with australia? write your answer in scientific notation.

6.21 times more

Step-by-step explanation:

Assuming 2.04 x 10^11 was only a typo

you would need to first equal the powers of 10

so 20.4 x 10^10 and 3.28 x 10^10

now that they have the same powers

if it's asking for how many times i would approximate it to 6.21 times more

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
