Bahahaha i am so bored rn
Answer:
Porosity of the sand is, 20 %.
Step-by-step explanation:
So according to the question,
10 mL of sand contains (5 - 3) mL = 2 mL of water and this water fills the gaps or pores between the sand partcles. So, porosity of the sand is given by,
%
= 20 %
You will want to solve for where y=0.
-6x - 2(0) = -18.
-6x = -18
x = 3
The equation's x-intercept is at (3,0)
area (pool)=area (rectangle) - area (triangle)
1) we calculate the area of the rectangle:
area (rectangle)=lenght x width
area (rectangle)=36 ft x 20 ft=720 ft².
2) we calculate the area of the triangle:
area (triangle)=(base x height) / 2
area (triangle)=(6 ft x 5 ft) / 2=15 ft².
3) we calculate the area of this pool:
area (pool)=720 ft²-15 ft²=705 ft²
Answer: the area of the pool is 705 ft².
