Abanana weighs 1.2 times 10 to the second power. how much do 10 bananas weigh

1,200

Step-by-step explanation:

To do this problem you do ten to the 2nd power which is 100 then you multiply 100 by 1.2 which is 120, which is then multiplied by 10 to get 1,200

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
