she can buy maximum of 19 balls.
Step-by-step explanation:
Let the number of volleyballs be x
we know that
so substituting the values,
Answer:
C
Step-by-step explanation:
Calculate AB using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 1, - 3) and (x₂, y₂ ) = B(11, - 8), thus
AB =
=
= =
= 13 → C
Answer:
3334650.54 euros
Step-by-step explanation:
We can calculate the area of the triangle knowing its sides by means of Heron's formula:
A =
Where p is the semi-perimeter is equal to:
now, we replace:
p = 518.5
now, we replace this value and we are left with:
A =
A = 50440.94 m^2
Now to know the price, we multiply by the price of the square meter:
50440.94 * 66.11 = 3334 650.54
In other words, the value of the parcel is 3334 650.54 euros
