Answer:
N = 10
Step-by-step explanation:
Normally the coordinate system goes:
x axis (horizontal)
y axis (vertical)
Here, we have:
Horizontal axis as "M", and
Vertical axis as "N"
We want to know what N will be when M equals 50.
So, we look at the x-axis and go to M equals 50.
Then we move up until the "trend line". The intersection.
If we move directly left to vertical axis (N variable), we see that it is at the point:
N = 10
So,
When M = 50, N = 10
You need to divide the miles by the hours to et the Average speed.
M divided by h = s
Because to get the mph (miles per hour) you multiply the average speed to the hours.
S•h=mph
The bar between the numerator and denominator of a fraction represent division.
Answer:
5/V2=2.5×V2
Step-by-step explanation:
This is an isoscelle right triangle:
x²+x²=5²
2x²=5²
x=5/V2=5×V2/2=2.5×V2
where V2=sqrt(2)
36.
90 times 2/5 (or 0.4) is equal to 36
