Answer:
Option (b).
Step-by-step explanation:
It is given that Adrian built a structure out of 10 congruent cubes.
Volume of each cube = 8 cubic centimetres.
We need to find the total volume of the structure.
Total volume = No. of cubes × Volume of each cube
Therefore, the total volume of the structure is 80 cubic centimetres.
Hence, option (b) is correct.
Answer:
10
Step-by-step explanation:
f(x) =3x-x=2x,
f(7-2)=f(5)= 2*5=10
We know that 15 elves represent the 20% of the total.
Since 20% is one-fifth, the total number of elves is

Alternatively, solve the proportion

which yields
