Answer:
B n>2
Step-by-step explanation:
−6n<−12
Divide each side by -6, remembering to flip the inequality
-6n/-6 > -12/-6
n >2
Answer:
A?? because I think it's not linear because it's not proportional
9514 1404 393
Answer:
a) 230
b) 300
c) 2×10^-2
d) 1.1×10^-6
Step-by-step explanation:
a) 0.26 × 890 ≈ 1/4 × 900 ≈ 225 ≈ 230
b) 1.95/(.67×10^-2) ≈ 2/(2/3)×10^2 ≈ 300
c) 2010×10^-5 ≈ 2×10^3×10^-5 = 2×10^-2
d) 9.98×10^-4/(9×10^2) = 9.98/9×10^(-4-2) ≈ 1.1×10^-6

YMMV depending on how you do the rounding and approximate multiplication and division.
The first one can be done multiple ways. For most accurate results, increasing one number while decreasing the other is recommended. (You don't want to compute 0.3×900, for example.)
The value square root of 3 is a value of a special triangle measuring 30-60-90. In this case, we are familiar <span>that the sin of 60 degrees is equal to square root of 3 over 2. and that the cosine of 60 degrees 0.5. tangent is sine over cosine, hence square root of 3 is equivalent. In this case, the answer should be 60 degrees. The negative and positive value inside the parenthesis is the same. </span>
