Let, the number of Surfboards sold last week = x
Then, x * 320% = 160
x * 3.20 = 160
x = 160/3.20
x = 50
In short, Your Answer would be Option B
Hope this helps!
Replace S with the given surface area:
2646 = 6x^2
Divide both sides by 6:
x^2 = 2646 / 6
x^2 = 441
Take square root of both sides:
x = √441
x = 21
The answer is D. 21
Answer:
3/4
Step-by-step explanation:
Number of sections = 8
Number of sections with numbers that are odd = 6
P(odd number)
= 6/8
= 3/4
Answer:
The amplitude is 4 and the period is 2
Step-by-step explanation:
In the equation y = A sin (B x)
- A is the amplitude, where the amplitude is the height from highest to lowest points and divide the answer by 2
- The period is , where the period is the distance from one peak to the next peak
∵ The equation is y = 4 sin(πФ)
- Compare it with form above
∴ A = 4 and B = π
∵ A is the amplitude
∴ The amplitude is 4
∵ Period =
∴ Period =
∴ Period = 2
∴ The period is 2
