4 P 4 = 24
4 P 4 = 4! (4-4)! = 4!/1 = 4*3*2*1
you are doing combinatorics, yes?
The picture isn’t visible it’s a black screen
0.81 = 81/100
0.5 = 5/10 = 1/2
0.63 = 63/100
0.214 = 214/1000 = 107/500
I don't know if I am right but I think this is the answer:
If we write beaker with x and content with y
then y=56.8/2=28.4 this is the content of one beaker
so there are two beakers:
2x+28.4=180.4
2x=180.4-28.4
2x=152/2
x=76
Step-by-step explanation:
180 + 20 + 5 suma eso y la respuesta está correcta
