A water pitcher weighs 1.72 kg when empty and 2.01 kg when filled with water. How much does the water weigh?
1 answer:
So the beginning weight is 1.72 kg, but the end result is 2.01 kg.
So you are trying to find what #(number) plus 1.72 equals 2.01
This can also be written as
You're trying to solve for x.
But since this problem is really simple, you just subtract 1.72 from 2.01
So, 2.01 - 1.72
Which equals to 0.29kg of water :)

Answer:
Step-by-step explanation:
The octagon is irregular, meaning not all sides have equal length. However, we can break it up into other shapes to find the area.
The octagon shown in the figure is a composite figure as it's composed of other shapes. In the octagon, let's break it up into:
- 4 triangles (corners)
- 3 rectangles (one in the middle, two on top after you remove triangles)
<u>Formulas</u>:
- Area of rectangle with length
and width
:
- Area of triangle with base
and height
:
<u>Area of triangles</u>:
All four triangles we broke the octagon into are congruent. Each has a base of 2 and a height of 2.
Thus, the total area of one is
The area of all four is then units squared.
<u>Area of rectangles</u>:
The two smaller rectangles are also congruent. Each has a length of 3 and a width of 2. Therefore, each of them have an area of units squared, and the both of them have a total area of
units squared.
The last rectangle has a width of 7 and a height of 3 for a total area of units squared.
Therefore, the area of the entire octagon is
