Use a ruler for this problem. Take a picture of the measurement & then I could help you.
Answer:
3 and 15
Step-by-step explanation:
Let's list the factors of 30:
1, 2, 3, 5, 10, 15, 30
Of these, the odd ones are:
1, 3, 5, 15
Of these, the only numbers that are multiples of 3 are 3 and 15.
Improper fraction would be 9/7
mixed number is 1 2/7
decimal 1.285714 repeated
Area of a circle is PI x r^2
The radius of the large circle is shown as 8 m
The diameter of A is the radius of the large circle which is 8 m so the radius would be 4 m
The radius of the small circle would be 2m
Area of large circle = pi x 8^2 = 64pi = 200.96 square m
Area of middle circle = pi x 4^2 = 16pi = 50.24 square m.
Area of small circle = pi x 2^2 = 4pi = 12.56 square m.
The area of the shaded region = large - middle + small
Area = 64pi - 16pi + 4pi = p2pi square m or 200.96 -50.24 + 12.56 = 163.28 square m.
We will be using the formula: Speed = Wavelength * Frequency
1. <u>Given:</u> Wavelength = 5 m and Frequency = 2 Hz
Speed of the wave = Wavelength * Frequency
Speed of the wave = 5 * 2
Speed of the wave = 10 m/s
__________________________________________________________
2. <u>Given:</u> Speed of the wave = 100 m/s and Frequency= 1000 Hz
Wavelength = Speed / Frequency
Wavelength = 100 / 1000
Wavelength = 0.1 m
__________________________________________________________
3. <u>Given:</u> Speed of the Wave = 25 m/s Wavelength = 5 m
Frequency = Speed / Wavelength
Frequency = 25 / 5
Frequency = 5 Hz
