Answer:
Any irrational number is added to 0.4 it will give an irrational number.
Step-by-step explanation:
We need to tell the number which produces an irrational number when added to 0.4.
An irrational number is a number which cannot be expressed in the form of fraction . In other words we can put that decimal expansion of an irrational number does not terminate or cease to end.
Now, if any irrational number is added to 0.4 it will give an irrational number.
Some examples could be: and any non-terminating number.

Answer:
Polygon q’s area is one fourth of polygon p’s area
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> polygon q’s area
y-----> polygon p’s area
so
In this problem we have
substitute
therefore
Polygon q’s area is one fourth of polygon p’s area
Answer:
Step-by-step explanation:
Area of a triangle is 1/2 * b * h
b = base, the one labeled b on the diagram
h = height, the dotted line in the middle
so, you do pythagorean theorem with a and b to find the dotted line
a² + b² = h² (h is for height)
h =
Then, you just plug in the numbers from question 3 to find h and then you do
1/2 * b * h
