Answer:
F. 82
Step-by-step explanation:
To calculate the length of BC, Pythagoras theorem will be used.
It says, Hypotenuse^2 = Perpendicular^2 + Base^2
In our case, Perpendicular = AB = 18 and Base = AC = 80
therefore,
Hypotenuse^2 = 18^2 + 80^2 = 6724
Hypotenuse = BC = = 82
Answer: C and B
Step-by-step explanation: because its rational.

To construct the equations for these lines, we are going to use the point-slope formula, which is:
- is the slope of the line
- is a point on the line
1)
In this case, our point is (2, -1) and our line has a slope of 5. (Remember that the line is parallel, meaning that it has the same slope as the given line. Since the line is in the y = mx + b format, we could easily pick out the slope m as being 5.)
Thus, we can "plug in" what we know into our formula to find the equation of our line:
2)
We are going to do the same thing, except our point is now (0, -5) and our slope is now 9.
Our equations are:
1) y = 5x - 11
2) y = 9x - 5
Answer:
42 cylinders
Step-by-step explanation:
we know that
To find out how many cylinders with a surface area of 0.9424m2 can be painted with one can of paint, divide the square meters that cover one can of paint by the surface area of one cylinder
so
Round down to the nearest whole number
42 cylinders
