Answer:
-69%
Step-by-step explanation:
1) Make Your Equation: 2.99x=2.07
2) Divide Each Side By 2.99:
=0.69
3) Make 0.69 A Percent: 69%
4) But Since It Is Decreasing Make It Negative: -69%
You can decide by seeing which one measures object better. you want to avoid using the incorrect unit because it can meaure it wrong or it won't be as accurate as the right unit

Step-by-step explanation:
Given
A proportional relation is given between minutes spend in reading and no of pages
Suppose we choose the point
, It shows that 2 minutes is taken to read three pages.
Similarly, for point
, It shows four minutes is taken to read 6 pages.
In this way, 6 minutes is taken for 12 pages.
This is the formula for the surface area of a cylinder including the ends, like the total surface area of a can of peas.
S = 2·π·r² + 2·π·r · H
Divide each side by 2·π·r :
S/2·π·r = r + H
Subtract r from each side :
H = (S/2·π·r) - r
or
H = (S - 2·π·r²) / (2·π·r)
