Answer:
slice priced $1.50 is better value
Step-by-step explanation:
Angles around a point add up to 360°
Area of a circle = πr²
360° ÷ 60° = 6
⇒ This slice is 1/6 of the whole pizza
⇒ area of the slice = (1/6)π × 6² = 6π in²
⇒ $1.50 ÷ 6π = $0.079577... per in²
360° ÷ 45° = 8
⇒ This slice is 1/8 of the whole pizza
⇒ area of the slice = (1/8)π × 7² = (49/8)π in²
⇒ $1.70 ÷ (49/8)π = $0.088347.. per in²
Therefore, the slice priced $1.50 is cheaper per in²
Answer would be B because I’m Geometry the cosine law is separated by different terms with either plus or minus sign presentation
Answer:
Step-by-step explanation:
So the slope of the line is y = -9x + b
We have
y = -9x + b
Add 9x to both sides
y + 9x = -9x + 9x + b
y + 9x = b
switching sides,
b = y + 9x
Plug in the (x, y) values for point (4, 0)
b = 0 + 9(4)
b = 36
So the equation of the line is
It is 21 Bc my tutor said ur was 21
Step-by-step explanation:
The ratio is the same each time (2/3), so this can be modeled as a geometric sequence.
an = a₁ (r)^(n-1)
where an is the nth term, a₁ is the first term, and r is the common ratio.
On the first rebound, the ball rises to 2/3 × 2 = 4/3, so a₁ = 4/3.
an = 4/3 (2/3)^(n-1)
On the sixth rebound, the ball rises to:
a₆ = 4/3 (2/3)^(6-1)
a₆ = 4/3 (32/243)
a₆ = 128/729
a₆ ≈ 0.176
