Answer:
Step-by-step explanation:
the general equation of a line is y=mx+c
because the slop is 1/5, the equation of this line would be
with the coordinates (20,5) , take 20=x and 5=y
and substitute these values into the equation above.
you should get:
5= 4 + c
so c = 1
therefore, the equation of the line is:
Answer:
It will be an equilateral triangle and the area is 1924.5 sq. meters.
Step-by-step explanation:
If the total length of the fencing of 200 meters is utilized then the perimeter of the triangle will be 200 meters.
Now, we know that the type of triangle that gives the maximum area for a given perimeter is an equilateral triangle.
So, the equilateral triangle with a perimeter of 200 meters will have side lengths of meters.
Now, the area of an equilateral triangle with sides a units is given by sq. units.
So, the area of the above equilateral triangle will be = sq. meters. (Answer)
Answer:
8,146 x 121
Step-by-step explanation:
This is a problem in which you need to measure your understading of "orders of magnitude."
If the estimated answer is that means that we are looking at a multiplication in the "order of"
You need to look at the "orders of magnitude" of the things you're multiplying. In the first case, we have that would be "of the order of"
times
. So the whole multiplication would "of the order of"
or near
The correct answer, 8,146 x 121, is because it's "of the order of" times
and the gives us the
we need.
