Answer:
The volume of the sphere is eight times the volume of hemisphere
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
x-----> volume of the hemisphere
y-----> volume of the sphere

in this problem we have

substitute



that means------> The volume of the sphere is eight times the volume of hemisphere
Mon had 100 kg of water, dumped it into 10kg of pure salt, namely 100% salt, what happened? well, it ended up with 100kg + 10kg, or 110kg of saline solution, off which 10kg are just salt.
so, if we take the 110kg to be the 100%, what is 10kg in percentage off of it? namely the salty part.
The two original functions are 4x+9y=7 and 4x-9y=9
To use the combination method, add all the values of the two equations together to cancel out one of the variables
4x+4x+9y-9y=7+9
8x=16
8x/8=16/8
x=2
4(2)+9y=7
8+9y=7
8-8+9y=7-8
9y=-1
y=-
im sorry this question doesnt make sese you cant have a slope represented by points on a graph
( such as (6,-5)
