Liono4ka [1.6K]
Let s = # of students in the sixth grade.  60% of these, or 0.60s, ate pizza:  thus, 0.60s = 36.  Solving for s, s = 36/0.60 = 60.

There are 60 students in the sixth grade.

Find all solutions of the equation in the interval [0, 2pi).
mina [271]

Answer:

x = 0 , π

Step-by-step explanation:

-4 \sin x = 1 - cos^2 x

  • Rewrite it by using the identity \sin^2x + \cos^2x = 1

=> -4\sin x = \sin^2x

  • Add 4sin x to both the sides.

=> -4\sin x + 4\sin x = sin^2x + 4\sin x

=> \sin^2x + 4\sin x = 0

  • Take sin x common from the expression in L.H.S.

=> \sin x(\sin x + 4)=0

Here , we can get two more equations to find x.

1) \sin x(\sin x + 4)=0

  • Divide both the sides by sin x

=> \frac{\sin x(\sin x + 4)}{\sin x} = \frac{0}{\sin x}

=> \sin x + 4 = 0

  • Substract 4 from both the sides.

=> \sin x + 4 - 4 = 0 - 4

=> \sin x = -4

=> x = No \; Solution

2) \sin x(\sin x + 4)=0

  • Divide both the sides by (sin x + 4)

=> \frac{\sin x(\sin x + 4)}{\sin x + 4} = \frac{0}{\sin x + 4}

=> \sin x =  0

=> x = 0 \; , \pi over interval [0 , 2π).

Answer:

the first one is 192 and the second is 396 the third is 216 the fourth is soapy suds

Step-by-step explanation:

the first you just do 4x6x8

the second you just do 9x8x11 and then divide by 2

the third you just multiply 9x6x4 or you could do 3x4x9 and multiply that by 2

the fourth is soapy suds bc it has a larger volume of 1248 while clean and bright only has a volume of 936
