1/11 = 0.09...with a line over the 09 because it repeats
-17/40 = - 0.425
-2 12/18 = -2.66...with a line over the 66 because it repeats
8 15/22 = 8.681....with a line over the 81 because it repeats
Triangles ABC and XYZ are similar, so the corresponding angle to A in XYZ triangle is angle X. We can actually find sin(X) very easily.
Because we know all sides and the right angle, we can use certain formula to find sin(X), like this:
sin(X) = opposite side / hypotenuse = 6/10 = 3/5
sin(X) = sin(A)
The correct answer is sin(A) = 3/5.
Answer:
100% increase from 100 is 200, the difference is 100.
100% decrease from 100 is 0, the difference is -100
error means that you were quite a long way off from the true value.

12d+3
Step-by-step explanation: multiply 3x4d and 3x1 and you get 12d+3
Answer:
(34, 48)
Step-by-step explanation:
According to the Empirical Rule, 95% of normally distributed data lie within two standard deviations of the mean. That, in turn, means 95% of the data in this problem lie within 2(3.5 min), or 7 min, of the mean:
41 - 7 < mean < 41 + 7, or
34 < mean < 48, or simply (34, 48)
