circurference of gear = 2πr
= 2π(10)
= 62.83185307 inches
= 62.83 inches (4sf)
She can only but 14 movies because 18.50÷1.25= 14.8 and then 1.25×14=17.5
Answer:
The circle's centre is at the position (3, 5), and it has a radius of 2
Step-by-step explanation:
First let's put it in a useful format by completing the squares:
x² + y² - 6x - 10y + 30 = 0
x² - 6x + y² - 10y = -30
x² - 6x + 9 + y² - 10y + 25 = -30 + 9 + 25
(x - 3)² + (y - 5)² = 4
This tells us that the centre position is (3, 5) and the radius is √4, or 2
Step-by-step explanation:
m = -91.3
Since you move from 91.3 to the other side of the equal sign, it becomes a negative number (-91.3)
Think of the equal sign as a seperator from the positive and negative side.
If you also get an equation like -x=91.3, just flip the -x, to x, and change the 91.3 to a negative 91.3!
Cheers!
