Answer:
Minimum 7 buckets of water is needed to completely fill spherical storage tank.
Step-by-step explanation:
We are given the following in the question:
Cylindrical bucket:
Radius, r = 6 inches
Height = 18 inches
Volume of bucket = Volume of cylinder

Spherical storage tank:
Radius, r = 15 inches
Volume of tank = Volume of sphere =

Number of baskets required =

Thus, minimum 7 buckets of water is needed to completely fill spherical storage tank.

Answer:
1.2
Step-by-step explanation:
First make -1.5 equal to 0.
We'll have to add 1.5, right?
So 1.5 is in 2.7.
So now its 0 + ? = ?
2.7 - 1.5 = 1.2
So 0 + 1.2 = 1.2
Hope this helped.
You can use substitution and solve y-x=2 for y which is y= x+ 2 and plug it into the y of the other equasion and you get x=5 y=7
