It is 2.4 cups of 10% fruit juice and berry punch and 9.6 cups of 20%fruit juice:
let x to be 10% fruit juice and berry punch and y= 20% fruit juice
.x+.2y=2.16
x+y=2.4
use substitution property or elimination property to solve the problem:
x=2.4 and y=9.6
If you're asking for the closest whole number to the square root of 149 - tis 12.
Answer: Simple cubic=0.39nm
Face centred cubic
=0.55nm
Body centered cubic
=0.45nm
Diamond lattice= 0.9nm
Step-by-step explanation: The lattice constant (a)
for SC=2*r
Fcc=4*r/√2
Bcc= 4*r/√3
Diamond lattice=8*r/√3
Here,
r is the atomic radius measured in nm
r = 1.95Å * 1nm/10Å
=0.195nm
Now let's calculate (a)
SC = 2*r = 2*0.195 nm=0.39nm
Fcc = 4*r/√2 =4*0.195nm/√2
= 0.55nm
Bcc = 4*r/√3 =4*0.195nm/√3
= 0.45nm
Diamond lattice = 8*r/√3
=8*0.195nm/√3
= 0.9nm
