A cube has side length a. The side lengths are decreased to 20% of their original size. Write an expression in simplest form for
sergiy2304 [10]
Volume of the original cube is a³ .
That's (a · a · a) .

If you decrease the sides to 20% of their original size,
then the new volume is  (0.2a · 0.2a × 0.2a).

That's  0.008a³  or  (0.2a)³ . 

Take your choice.  I can't decide which one is simpler.

Virty [35]

Answer:

equation: 28 = 2h+ h + h or you could say 28 = 4h

h= 7

Step-by-step explanation:

since both lines are the same length they equal each other.

to get h = 7 you have to solve the equation you made.

28 = 4h

28/4 = 4h/4

7 = h

Plzzzzzzzzz anyone helpppppp10points
BlackZzzverrR [31]

when is 9 = 15.2 - 0.537x

         9 = 15.2 - 0.537x

  -15.2      -15.2                 subtract 15.2 from both sides

      -6.2   =   -0.537x  

/-0.537           /-0.537    divide -0.537 from both sides

11.55  = x   or 12 feet round to nearest whole foot
