grade 6 honors math
as the summation 50+65+70=185 and some students chose none, so it is greater than 150 total students. so the sets can't be disjoint. there are students who took more than 1 elective.

360*218/245 compute this it will give angle in degree
Algebra 2 ..
1> even factors of 4*5 =20 so the factors are 1, 2 ,4 ,5 ,10 ,20 among them 2,4,10,20 are even. 3> here 4 is the minimum no of +ve factors. n will have the factors, =1*n =p*q including 1 and n, n have minimum 4 factors. it could be more. ***for Q2 I have not understood.
where are the cubes??
multiple of 3 are 3,6 so the probability is 2/8
so you have, (n-2)+(n-1)+n+(n+1)+(n+2)=2005 5n=2005 n=401 nos are, 399,400,401,402,403
(1-1/3)*1*V=(1-3/4)*p*V p=8/3=2.6667 gm/cc
Quick Math Question
add them!! adding it comes 11 hrs subtract 11 from 12
Use the remainder theorem
remainder is=f(-2) f(-2)=2(-2)^6-8(-2)^4+(-2)^2-5 =-3 so (x+2) is not a factor of f(x)
(47-32)*5/9 =8.333333333333 degree centigrade
Algebra multiple choice!
for 2 answer is <d> 1 is ok
P((x-72)/9)=90% (x-72)/9=1.28 [normal distribution table] x=83.52 83.52 at least for getting A P((x-72)/81)=10% (x-72)/81=-1.28 [normal distribution table] x=60.48 60.48 maximum for getting D for B, score is between 72 and 83.52 for C, score is between 60.48 and 72
yes this is true.
d>=51+12 d>63 or d=63
the normal force on the block, mg-p*sin_theta along the motion, p*cos_theta=u*(mg-p*sin_theta) theta=30 u=.6 m=300 kg p*(.866+.5*.6)=.6*300*9.8 p=1512 N if p is individual of two force then, p=1512/2=756 N
2.5 m from where? right end or left end?
total arrangement=(6+3-1)!=8! with 2 girls sit beside, arrangement possible=3C2*(6+2-1)!=3*7! probability 2 girls always sit beside=3/8 answer=1-3/8=5/8
V=pi*r^3 dV/dt=3*pi*(r^2)*(dr/dt) dV/dt=.1 r=2 pi=3.14 dr/dt=?
mean is calculated as the average value. summation of all values divided by number of values is mean. and median is the value present in the middle of a sequence of numbers.
I am solving the first one.....second one you can try yourself. so 9x^4+4=13x^2 this can be written, x^2*(9x^2-13)=-4 as x^2 is always +ve so to be -ve, (9x^2-13)<0 we see that -(sqrt(13)/3)<x<(sqrt(13)/3) it comes as -1.2<x<1.2 next we will see if there is some...
he spend (1/4+1/2)=3/4 of his total money. so has remaining money=(1-3/4)=1/4 of total money. he had total money=$58*4=$432

the area of the path that is running along the breath is= 450*5=2250 m^2 the area of the path that is running along the length is= 750*5=3750 m^2 but as the two roads cross each other in the middle if we just sum the two areas it would over-estimate the crossing area. so to ne...
1> Phloem Transportation of food and nutrients such as sugar and amino acids from leaves to storage organs and growing parts of plant. This movement of substances is called translocation. Xylem Water and mineral transport from roots to aerial parts of the plant. 2> Phloe...
well you can understand it like, for one qusetion getting right, the probability is=.5 as there are only two options true and false. for two qusetion getting right, the probability is=.5*.5 for three qusetion getting right, the probability is=.5*.5*.5 ............................
2cos^2(x)=2-2sin^2(x) substituting, 5-2+2sin^2(x)-7sin(x) = 0 it comes as 2p^2-7p+2=0 where p=sinx solving p=13/4,1/4 as sin(x)<=1 so sin(x)=1/4 a=1 b=4 a+b=5
at time 0 the position is (0,0) at any time t, the distance wold be, =sqrt((t-sint)^2+(1-cost)^2) =sqrt((t-sint)^2+(1-cost)^2) =sqrt(t^2+2-2(cost+tsint)) now integrate this from 0 to 2pi to get the answer. wolframalpha refer to the site to get ur integration done.
1-cos(power 2)x= sin(power 2)x sin(power 2)x/sin(x)=sin(x)
taking the ininverse, (-x^2 + 2)/2x=-x/2+1/x so the answer is =1/((1/x)-(x/2))
