Answer:
No because (6, 4) is on the line
Step-by-step explanation:
x = 6
y = 4
1
4 > ------- 6 + 7
2
6
4> ------ + 7
2
4 > -3 + 7
4 > 4
that is not true so the answer is no because ( 6, 4) is on the line

so, the amount of work done by Mark in 1 minute is
younger sister Lynn can clean the office in 40 minutes
so, the amount of work done by younger sister Lynn in 1 minute is
total work done by them in 1 minute is
now, we can simplify it
total time taken to complete same work is ........Answer
So first of all, to solve this, we need to know the formula for finding the surface area of a cone. The formula is :
Where SA stands for surface area, h stands for height, and r stands for radius.
In the given information, we are not told the height, but we are told the slant height.
In a cone, the slant height, the height, and the radius together form a right triangle. We can use that triangle to solve for the height
So, to find the height, we can do:
5^2+b^2 = 12^2, or 25+b^2 = 144
Therefore, b is equal to about 11
So now, we can plug all of our values into the formula
This gives us:
If we solve, this gives us about 267.
Therefore the answer is 267 feet squared
Hope this helped!! :D
