Let
x-------> the whole number
y------> the decimal number
we know that
------> equation 1
assume the value of x and then calculate the value of y
Let
x=280
solve for y in the equation 1
substitute the value of x
therefore
<u>the expression is equal to</u>
280*0.001=0.28
Answer:
Area of ΔXYZ = n(r * r) square units
Step-by-step explanation:
Sides of ΔABC are 30 units, 40 units and 60 units.
Corresponding sides of another triangle XYZ are r times as long as the sides of ΔABC.
Therefore, sides of ΔXYZ will be, 30r units, 40r units and 60r units.
Perimeter of the triangle XYZ = 30r + 40r + 60r
= 130r units
If the area of ΔABC = n square units
Then the ratio of the area of ΔXYZ and ΔABC = (Ratio of the sides of ΔXYZ and ΔABC)²
Area of ΔXYZ = nr² ≈ n(r * r)
Therefore, Option (3) will be the answer.
