Given : The addition 21.4 + 15 + 17.17 + 4.003 by the rules for significant figures.
Solution: According to given numbers, let us count number of significant figures in each of the given numbers.
21.4 has three significant figures.
15 has two significant figures.
17.17 has four significant figures.
4.003 has four significant figures.
We have to round the final answer to the nearest tens place because 15 has only accurate to the ones place.
We can see that other numbers are accurate to the tenths, hundredths and thousandths places, respectively.
Let us add them as usually first,
21.4 + 15 + 17.17 + 4.003.
It gives 57.573.
Now, we need to round it to the ones place.
We get 58 as the final answer.
Answer:
30lbs of recyclables.
Step-by-step explanation:
-Let x be the corresponding lbs of recyclables to 40lbs of trash.
-Given that for every 100lb of trash, 75lb is recyclable.
-We determine the ratio of trash to recyclables and use it to calculate the amount correspond to 40lbs of trash:
Hence, thee are 30lbs of recyclables in 40lbs of trash.
The second answer that uses = is not correct, because the pentagons are similar not congruent.
The third answer is not correct, because that sign means estimated, not similar.
I've never seen the fourth sign, so by process of elimination I believe the answer is the first one.

The equation of line passing through (-8, -2) and (-4, 6) is y = 2x + 14
<u>Solution:</u>
Given that
Line is passing through point (− 8 ,− 2) and ( -4 , 6 )
Equation of line passing through point is given by:
----- eqn 1
Substituting given value in (1) we get
Thus the required equation of line is y = 2x + 14
