Answer:
9/10
Step-by-step explanation:
Since there is only one marble per number and there is only one marble for the number 8 you would take just subtract 10-1 which would give you 9.
Answer:
The constant of proportionality in the equation y=0.41 is 0.41
Step-by-step explanation:
20,000 Hz = 2 × 10^4 Hz
150,000 Hz = 1.5 × 10^5 Hz
Answer:
centre = (-5, -4)
radius = 7.42
Step-by-step explanation:
The general form for center-radius is
(x - h)² + (y - k)²= r²
Center = (h, k)
Radius = r
Rearrange the equation.
(x² + 10x) + (y² + 8y) - 14 = 0
Add 14 on both sides.
(x² + 10x) + (y² + 8y) = 14
(10/2)² = 25
(8/2)² = 16
Add 25 and 16 to both sides.
(x² + 10x + 25) + (y² + 8y + 16) = 14 + 25 + 16
Factor left side of the equation.
(x+5)² + (x+4)² = 55
(55) = (7.416198)²
(x+5)² + (x+4)² = 7.42²
The radius is 7.42.
The centre is at (-5, -4).
As a decimal .375 as a percentage it would be 37.5
