Answer:
y = mx + b
-1.8 is the slope
-1.8 in fraction form is -9/5
-9/5
Step-by-step explanation:
Answer:
Step-by-step explanation:
It is given that a meteorologist is using a Doppler radar to find out the distance of the storm as it passes using a polar grid.
The origin of the radar screen is its center.
And the distance between each ring is 10 miles from the center.
So let :
r = radius
h and k = be the coordinates of the center.
So the equation of a circle is :

Now the equation of the fourth circle when the radius changes by 10 miles is :
Answer:
3 hundredths or .03
Step-by-step explanation:
M= 2.8
Alternate form:
14/5 or 2 4/5
Answer: total is 200
Step-by-step explanation:
30% = 60
10% = 60/3 = 20
100% = 200
