Therefore, when ${8-i}/{3-2i}$ is rewritten in the standard form a + bi, the value of a is 2. ANSWER EXPLANATION: The volume of the grain silo can be found by adding the volumes of all the solids of which it is composed (a cylinder and two cones). Thus, 5*10, or 50, of the 122 right-handed students are female. To find what fraction of the circumference the length of ${AB}$ is, divide the length of the arc by the circumference, which gives $/3 2$. This way you are setting up the childs successful future. The equation ${24x^2 + 25x -47}/{ax-2} = -8x-3-{53/{ax-2}}$ is true for all values of $x2/a$, where $a$ is a constant. Check out our top-rated graduate blogs here: PrepScholar 2013-2018. So, the total effective amount paid is 9*3 = 27 and the amount given to beggar is Rs.2, thus the total is Rs.29. if there is a total of 18 left-handed students and 122 right-handed students in the school, which of the following is closest to the probability that a right-handed student selected at random is female? The SAT is a marathon and the better prepared you are for it, the better you'll feel on test day.

To solve an algebraic expression, simplify the expression by combining like terms, isolate the variable on one side of the equation by using inverse operations. The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of ${5}/{9}$ degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true: An increase of $5/9$ degree Fahrenheit leads to an increase of ${25}/{81}$, not 1 degree, Celsius, and so Statement III is not true. The graph of $y = k$ is a horizontal line that contains the point $(0, k)$ and intersects the graph of the cubic equation three times (since it has three real solutions). This equals, $$({8-i}/{3-2i})({3+2i}/{3+2i})={24+16i-3+(-i)(2i)}/{(3^2)-(2i)^2}$$, Since $i^2=-1$, this last fraction can be reduced simplified to, $$ {24+16i-3i+2}/{9-(-4)}={26+13i}/{13}$$.
