All the students in 6th grade got to choose which movie they wanted to
go see for an end of year celebration. They could choose either Jumanji
or Star Wars. • 15% of students chose Jumanji. • 68 students . how many students are their in 6th grade .

There about 453 students in 6th grade.

Step-by-step explanation:

68/0.15 453.3333...

453.333.. is a repeating decimal and we can't have that as a students so if has to be a whole number which is 453.

check: 453 * 0.15 =  67.95 which rounds up to 68.

So about  385 of the students chose Star Wars.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
