Answer:
-11 =d
Step-by-step explanation:
22/d = -2
Multiply each side by d
22/d *d = -2*d
22 = -2d
Divide each side by -2
22/-2 = -2d/2
-11 =d
Answer:
<h2>m∠GEF = 18º since it is marked as congruent to ∠DEG, so putting them together we get m∠DEF = 36º. Since the angles in the triangle need to add to 180º and angles D and F are congruent, we could write the equation 2x + 36 = 180 where x stands for ∠F.</h2>
All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point.
Answer:
a. 199,389
b. b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.
Step-by-step explanation:
a. Population in 2009 = 192,370
This means that in 2005 the population = 192,370 x 1.009 x 1.009 x 1.009 x 1.009 = 199,389
b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period.
