the math behind it:
your equation looks like this: .25x = 10
then you divide both sides by .25 and then ur equation looks like this: x=40
by the way the variable x stands for the number you are looking for. and since x=40, the number you are looking for is 40
well i hope i helped!
Answer:
C
Step-by-step explanation:
Your equation is 6/25 = d/30. to solve this equation we have to get d by itself! to do this, you have to multiply each side by 30 since d is being divided by thirty. d/30 x 30 = d, 6/25 x 30 = 7.2, or 7 2/10
therefore, d = 7.2

Here's the solution,
the volume of the given figure is :
=》

volume of pyramid :
=》

=》

=》

=》

volume of pyramid = 40 cm³
now, volume of rectangular prism :
=》

=》

=》

volume of rectangular prism = 40 cm³
volume of composite figure = 40 + 40
=》80 cm³
