Hey there!☺
as a scientific notation would be written like this:
Hope this helps!
Pythagoras theorem is used in scalene triangles to work out the other side length to do this you would need to follow the rule a2+b2=c2 in order to calculate the hypotenuse
2 inch is 10 miles
0.5 inch is 2.5 miles
so it is 12.5 square miles?
Answer:
a. (53, 12)
b. I couldn't find this without making a graph myself, hopefully someone will find it or you can figure it out for yourself using the answer I did provide.
The first statement "<span>y varies directly as x" means that as y increases, x also increases. To help us we need to assign a proportionality constant, k. We can now say:</span>
y=kx where k is just a constant. Then substitute the values,
180=kn
n=5k
With these equation we know that k is equal to (positive or negative) 6 and therefore we can get n to be (positive or negative) 30.
