Answer:
11. B
12. D
Step-by-step explanation:
11)
2 times 10⁻² = 2·0.01 = 0.02 ≈ 0.0201
12)
6·10⁻⁴ = 6·0.0001 = 0.0006
However, 0.00058 rounds to 0.0006 and 0.00067 rounds to 0.0007, so the answer is a better estimation for D than for B.
A percentage is a number that represents a ratio expressed as a fraction of 100. It means parts per 100. 1% would then mean 25 parts per 100. We solve the given statement above as follows:
1% (7) = (1/100) (7) = 0.07
Hope this answers the question.

Answer:
Step-by-step explanation:
Im pretty sure the answer is 1.4 or D
Answer:
Step-by-step explanation:
hello : 14x + 13y = -8
19x + 14y = 11
test : put x=5 and y=6
14(5)+13(6)≠ -8
conclusion : (5 , 6) is not solution
