Answer:
6%
Step-by-step explanation:
This is an honest guess just because you are not given the content of 2 out of the 3 bags. When starting at 100 percent of the makeup of the porridge you can then divide that by 3 to get the content of 1 bag.

Since the shower block is in the form of a rectangle. The shower block has an area of 144
. It has a length of 24m. We need to calculate the width of the shower block.
Area of rectangular shower block = length
width
144
= 24 m
width
width = 
width = 6m
So, the width of the shower block is 6 meters.
Answer:
the answer is triangles ABC and DEC are similar
Step-by-step explanation:
angle C is a common angle for both triangles
angle D is equal to angle A ( corresponding angles)since they are parallel
angle B is also equal to angle B for the same reason as angle D and A
since the three angles of the two angles are equal they are similar
