Whatever% of anything, is just (whatever/100) * anything.
there were a total of 560000 votes, now, off those some are valid and some are invalid.
we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.
how many are the valid ones anyway? well, 85% of 560000, which is just (85/100) * 560000.
we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?
well, (75/100) * [ (85/100) * 560000 ].
We have that the answer is 7 units. A property of the perpendicular bisector of PQ (which can be used to define it) is that every point on it has the same distance from both P and Q. A proof of this is the following: Consider the shape if we join U with P and Q. There are 2 triangles, PTU and QTU. We have that the two T angles are 90 degrees, PT=TQ since T is the midpoint and the leg UT is common. Hence, by side-angle-side we have that the triangles are equal, hence UP=UQ
Step-by-step explanation:
we simply use the formula and use 3.14 for pi.
so, the circumference is
2×pi×r = 2×3.14×4 = 3.14×8 = 25.12 in
so, D is correct.
15 x 3= 45 so 3 hours is the answer
