Answer:

2

Step-by-step explanation:

it starts out with 18 students, 24 pets in total. -16 for the dogs and cats, to lead up to 8, and 10 students left after subtracting 8 for how many students don't have a pet at home. So 2 students shouldn't have four legged pets left after subtracting the rest.  (this is my answer, it's probably wrong, i think you should wait for more,)

1-cos(12x)=<br> A. 2sin^2(6x)<br> B. 2cos^2(6x)<br> C. 2cos^2(12x)<br> D. 2sin^2(12x)
Y_Kistochka [10]
Cos(12x) = cos(6x+6x) = cos6xcos6x -sin6xsin6x = cos^2(6x) -sin^2(6x)

1 - cos(12x) = 1 - (cos^2(6x) -sin^2(6x)) = sin^2(6x) +cos^2(6x) - cos^2(6x) +sin^2(6x) = 2sin^2(6x)

so choice A. is right sure

There are a total of 96 children in Years 4, 5 and 6
BaLLatris [955]

Answer: 20 children

Step-by-step explanation:

<u>Given</u>

Year 4: 11 cannot swim

Year 5: 21 can swim

Year 6: 18 of 30 can swim

Total 96 children

Total 37 cannot swim

<u>First Step: find the number of people from year 5 who cannot swim</u>

  • There are 30-18=12 people who cannot swim in year 6
  • There are 11 who cannot swim in year 4
  • Thus, we use the total number [37]-[year 4+year 6]=37-23=14 people who cannot swim in the year 5

<u>Second Step: find the number of children in year 5</u>

  • There are 21 children who can swim
  • There are 14 children who cannot swim
  • 21+14=35 children

<u>Third Step: find the number of children in year 4 who can swim</u>

  • There are 30 children in year 6
  • There are 35 children in year 5
  • There are 11 children in year 4 who cannot swim
  • There are in total 96 children
  • 96-30-35-11=20 children in year 4 who can swim

Hope this helps!! :)

Please let me know if you have any questions

А<br> _has two-fold rotational symmetry.
Phoenix [80]
