45% as a multiplier is 0.45
So if you didn't know x^2 + y^2 = r^2 is the equation of a circle where the center is at the origin. It is usually written as (x-h)^2 + (y-k)^2 = r^2. So if we are moving it to the left by 8 units we write:
(x+8)^2 + (y-k)^2 = 16
Next we move it 3 units down, so we get:
(x+8)^2 + (y+3)^2 = 16
That is your answer. Hope this helps! :D
Answer:
133
Step-by-step explanation:
19x7
The fraction of the entire class paired for the game is: 24/31
<h3>Fraction of the entire class paired for the game</h3>
From the task content:
- It follows that; (3/4)x = 4/5y
Hence, it follows that;
By substitution;
Hence;
- (3/4)×16/31 = 12/31
- (4/5) × 15/31 = 12/31
Hence, the fraction of the entire that was paired is; 12/31 + 12/31 = 24/31.
