Answer:
3d figures - "a three-dimensional shape can be defined as a solid figure or an object or shape that has three dimensions – length, width and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth." -Google
Some Examples are...
- cones
-cylinders

Answer:


Step-by-step explanation:
Given a parallelogram ABCD is shown with DC equal to 9 feet and the perpendicular distance between AB and DC equal to 8 over 9 foot.
Part A: we have to find the area of ABCD.



Part B:
We have to decompose this parallelogram into two triangles.
Join diagonal AC
As the diagonal of parallelogram divides it into two congruent triangles of equal area
Hence, the area of each triangle is


So to figure out 10% of this would be to remove the 0. that would be six. since 30÷10 is 3, we have to do 6×3. that would be 18, so 30% of 60 is 18
Let's see here... well, since the first letter in the ratio is from the first triangle, then, the first one in the equal ratio is going to have to be that as well, and the ratio of c:a wouldn't work, since c was already used. By process of elimination, it's gotta be b:q.
$1.50- $0.9
=$0.6
Percent discount=
$0.6/$1.5 x 100
=40%
Check answer=
40/100 x $1.5
=0.6
$1.5- $0.6 = $0.9
(I hope this solution help!)
