Answer:
b
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius
The circle shown is centred at the origin and has a radius of 5, thus
x² + y² = 5² ⇒ x² + y² = 25 → b
It can be any number so here is my awnser 437
We solve the equation (1/6)x + 14 = (3/4)x, where x is the number of gallons;
We have 2x/12 + 168/12 = 9x/12;
2x + 168 = 9x;
168 = 7x;
x = 168 ÷ 7;
x = 24 gallons;
this would look like this: 0.0000001^10
If we were to do 0.0000001*0.0000001 it would be 0.00000000000010
We doubled the zeroes and moved the one up. Continue on until you reach the tenth power.
