Answer:
Its c
Step-by-step explanation:
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 ].
what’s the answer? i’m doing that quiz rn i’m on this question.
Answer:
x=1+√5 or x=1−√5
Step-by-step explanation:
Let's solve your equation step-by-step.
x2−2x−4=0
Step 1: Use quadratic formula with a=1, b=-2, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−2)±√(−2)2−4(1)(−4)
2(1)
x=
2±√20
2
x=1+√5 or x=1−√5
Hope this helps!! :D Happy Tuesday!
Answer.... 32
when a number doubles, it is simply a higher power of 2
so there are 3 butterflies in the beginning, which can also be written as 3 * (2^0) where the 0 is the initial power, since anything to the 0 power is 1 (except for 0)
so the expression would be 3 * (2^n)
after 4 minutes, it would be 3 * (2^4) or 3 * 16 or 48
to find out how many are remaining, we know that she captured 7 of them, so it would be 3 * (2^4) - 7
for question 2, Jeff texts 4 classmates, and then they each text 4 classmates, so that would be 4^2 or 16, but since 2 people do it, it would be
32
