After 3/4 hours, 2/3 of project is done.
After 1 hr, .... project is done.
In other words,
2/3 of project ---- 3/4 hours
? of project ------ 1 hour
The more Katie works, the more the project nears completion. This is a direct proportionality kind of relationship.
Therefore,
Part of project completed in 1 hour = (2/3*1)/(3/4) = 2/3*4/3 = 8/9
The slope of a line who is perpendicular to another, is the negative reciprocal slope of that line, that is, if a line has slope say a/b, then
so.. what is the equation of a line whose slope is 1/2 and passes through (2,5)?
Answer:
9
Step-by-step explanation:
V=πr²h
2797.74=πr²11
2797.74÷11π=r²
81=r²
√81=r
9=r
