Answer:
0.512a³ cubic units
Step-by-step explanation:
Given a cube of length, a, then when decreased by 20%, what's left is actually 80% of the original. So, for this case, we have a cube with a length of 80%(a) = 0.80a.
Now, to compute for the volume of a cube, we multiply the length three times to itself. Or, in other words, raise the length to the third power. That means the volume of the new cube is (0.8a)³ = 0.512a³ cubic units.
Answer:
18 pieces
Step-by-step explanation:
divide 30 by 5
you'll get 6
so one-fifth is equivalent to 6 of the pieces
multiply 6 by 2
you'll have 2 so two-fifths is equal to 12 pieces of rice crispy treats
subtract 12 from 30
30 - 12 = 18
So she took 18 pieces to school.
Solve one of the equations for one of the variables. then plug that into the other equation. solve.
let's solve the second equation : x = 3/2y + 13
plug it in : 4(3/2y + 13) - 3y = -2
solve : 6y + 13 - 3y = -2
3y = -15
y = -5
