Answer:
-22%
Step-by-step explanation:
The percent decrease can be found by subtracting the original amount from the sale price. Divide the result by the original price and multiplying the decimal by 100 for the percent.
670.80 - 860 = -189.2
-189.2/860 = -0.22
-0.22*100 = -22%
To determine the effect of changing the diameter of a sphere to its volume, we would need to know the formula for the volume of a sphere which is V = 4πr³/3 where r is half of the diameter. As you can see, there is a direct relationship.
r1 = d1/2
r2 = d2/2 = 2d1/2 = d1
V2/V1 = (4πd1³/3) / (4π(d1/2)³/3)
V2/V1 = 8
Therefore, the volume of the sphere would be 8 times the original volume.

Step-by-step explanation
if my answer is wrong i'm sorry here is a manual on how to do it if its wrong
i think they are right but just in case
Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
1 relation
2 function
3 relation
4 function
i know 4 is right but i don't know about others double check i suggest just in case i think they are right
