If 1.2 kilograms of rust form on a bridge in five days, what should be the rate of reaction in grams per hour? (recall that a bar over the number means that zero is significant.)
100(first zero has bar over it) g/hr
0.05 g/hr
0.010 g/hr
10(zero has bar over it) g/hr

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:

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
