There are 24 students in a class. 8 of them are boys. How many girls are there?

16

Step-by-step explanation:

24-8

if 8 are boys, the remainder must be girls because schools do not recognise gender queer people

16

Step-by-step explanation:

24-6= 16

16+8= 24

16/8=2

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
