Answer:
question 2 is true
question 3 is false
Step-by-step explanation:
Answer:it should be B and D
Step-by-step explanation:
B could be rotated clockwise and D could be rotated clockwise as well.
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
Five ten-thousandths looks like this: 0.0005
All of these are less:
0.0004
0.0003
0.0002
0.0001
0.00001
0.000001
.
.
etc.
The equation would be 30+3m=162 then you solve the problem
