Step-by-step explanation:
A capacidade da piscina é de x.
Para encher 2/5 de uma piscina são necessários 60.000 litros de água.
Isto implica que:
A capacidade dessa piscina é de 150.000 litros de água.

Answer:
4 free wedges of cheese
Step-by-step explanation:
From the above question:
3 sticks of butter purchased = 1 free wedge of cheese
12 sticks of butter purchased = x
Cross Multiply
3 × x = 12 × 1
x = 12/3
x = 4 free wedges of cheese
Therefore, when Baby Jr. Buys 12 sticks of butter, she will receive 4 free wedges of cheese.
Each petal of the region
is the intersection of two circles, both of diameter 10. Each petal in turn is twice the area of a circular segment bounded by a chord of length
, which implies the segment is subtended by an angle of
. This means the area of the segment is
This means the area of one petal is
, and the area of
is four times this, or
.
Meanwhile, the area of
is simply the area of the square minus the area of
, or
.
So
(provided these regions are indeed disjoint; it's hard to tell from the picture)
