20/ 18
Step-by-step explanation:
Ratios can be writen in 3 different formats. You can write your ratios in fraction form (Example- 20/18), colan form, (Example- 20:18) and finaly word form (Example- 20 to 18). Hope this was acurate and helpful. Have a magical rest of your day!
Answer:
A note has a wavelength of 0.77955 m. If the speed of sound is 343.00 m/s, what pitch is this note?
f = (343m/s) / 0.77955m = 439.997 0r 440 Hz Pitch is an A.
Step-by-step explanation:
Answer:
The perimeter of triangle is 30ft.
Step-by-step explanation:
First you have to find the value of a using Pythogoras Theorem, a² + b² = c² where a and b is the sides and c is the hypotenuse :
Let b = 12,
Let c = 13,
Next you have to find the perimeter of triangle by adding all the sides together :
3 next number in the given pattern: 3.5 , 13, 41.5, 127,
_______, _________, ________
<span>We have the first 4 given pattern, next is to find the next
3 consecutive numbers:
x = numbers we’re looking
g =given numbers
=> 3.5g + x = 13
=> 13g + x = 41.5
=> 41.5g + x = 127
Now, let’s remove the decimals, multiply by 2
=> 2(3.5) + 2x = 2(13)
=> 7 + 2x = 26
=> 2 (13) + 2x = 2(41.5)
=> 26 + 2x = 83
=> 2(41.5) + 2x = 2(127)
=>83 + 2x = 247
Now, we already have whole numbers. Next is to solve the value of x’s and g’s
2x = 26-7
26 + 26 = 7 = 83
19 + 26 = 83
19 = 57
g = 3
2x = 26 -7
2x = 26 – 7 (3)
2x = 26 – 21
2x = 5
x = 2.5
Now, let’s find the next 3 consecutive numbers
=> 127 (3) + 2.5 = 383.5
=> 383.5 (3) + 2.5 = 1153
=> 1153 (3) + 2.5 = 3461.5
The next 3 numbers are 383.5, 1153, 3461.5</span>
