600,000 pound = 300 tons
3 * 10^n = 300
10^n = 100
10^2 = 100
so n = 2
Answer:

Step-by-step explanation:
To factor this, you must first take out the GCF (Greatest Common Factor), that
and -147 both have. The terms only have 3 in common, which can be divided with

However, we're still not done since 49 is a perfect square and
can be split into 2, like so:

If you're unsure about the final answer, you can multiply it all together to see if you got the original expression.
Answer:
84 degrees.
Step-by-step explanation:
First, let's define what a complementary angle is. It's when two angles add up to 90 degrees. So we do 90-6=84 and 84+6 does in fact equal 90, so they are complementary.
Answer:
D=100(opposites angles are equal)
A=C=80 (adj angles are supplementry)
