Answer:
88 cm²
Step-by-step explanation:
Each square is 1 cm². Count the squares of each face and add them.
Front face (purple): 14 cm²
Back face (hidden): 14 cm²
Right lower face (orange): 6 cm²
Right upper face (orange): 6 cm²
Left face (hidden): 12 cm²
Upper top face (blue): 3 cm²
Lower top face (blue): 15 cm²
Bottom face (hidden): 18 cm²
Add all areas above:
88 cm²
So car A travels Distance = 60 km/hr*(1+x)
Car B travels Distance = 75 km/hr(x)
Where x is the time in hours.
Those two equations are equal when on overtakes the other
so:
60 +60x = 75x
60=15x
x=4, but my expression is written to count from when car B commenced travel. So total time is 5 hours from the car A setting off.
Answer:
The atomic weight (or atomic mass) of Vanadium is 50.9415 which means that a "mole" of Vanadium atoms (6.02 x 10^23 atoms) will have a mass of 50.9415 grams. So, 214.1 grams of Vanadium would have
(214.1 / 50.9415) * (6.02 x 10^23) = 2.530 x 10^24 atoms
