Answer:
120 000 m^2
Step-by-step explanation:
I ASSUME you're being asked to convert from km^2 to m^2.
For this you need to identify the conversion rate, which is 1 000 000 m^2 / 1 km ^2. Multiply by the thing you're converting from and cancel the units.
(1 000 000 m^2 / 1 km ^2) x 0,12 km^2 = 120 000 m^2 (the km^2 cancels out, leaving you only with your target unit of m^2)
Constant of Proportionality = d/t = 90/2 = 45 mph
In short, Constant of Proportionality would be: 45 miles per hour.
Here, d/t = 45
d = 45t
In short, Your Equation would be: d= 45t

Answer:
40 mm
Step-by-step explanation:
It's 40 mm because the Pythagorean Theorem explains a^2 + b^2 = c^2.
This means the unknown number plus 30^2 = 50^2
What you want to do is 50^2 - 30^2= 20^2; which would be 2500-900=1600.
You got 1600 but that isn't your final answer. You want to find the square root 1600. So 1600 square rooted is 40.
40 mm is your final answer.
