(XX) = 1,000*20 = 20,000 Or XX with a bar above each numeral
What is 20000 in Roman Numerals?
The number 20,000 can be written in Roman numerals as [XX] or as XX with a horizontal bar placed above it (which I cannot write with this keyboard).
What is the second number above the equal sign is called the in a subtraction problem?
subtrahend
A man invests 20000 at an annual interest rate of 7 percent and 12000 at an annual interest rate of 7.5 percent what was his annual income on the two investments?
O.K. First of all, you need to know that I = P X R X T...Interest equals principal times rate times time. I = 20000 X .07 X 1 ++++++++++++++++ I =12000 X .075 X 1 (That's 7% above and 1 is for 1 year, see?) I = $1,400 I = $900 Now, add the two numbers above, 1400 + 900 = $2,300. That's it, easy huh?
What is the roman numeral of 18985 and 26495?
1. 18985 Roman Numeral for: 10000=X with horizontal bar above it 5000=V with horizontal bar above it 3000=MMM 900=CM LXXX=80 V=5 ..........................__ Therefore:18985=XVMMMCMLXXXV 2. 26495 Roman Numeral for: 20000=XX with horizontal bar above it 5000=V with horizontal bar above it 1000=M CD=400 XC=90 V=5 Therefore: ...........___ 26495=XXVMCDXCV
How fast does something have to vibrate to produce sound?
Sound is produced by vibrations that travel through a medium, such as air. For human hearing, these vibrations typically need to occur between 20 Hz and 20,000 Hz. Below 20 Hz, the vibrations are too slow to be audible, and above 20,000 Hz they are considered ultrasonic.
The number of vibrations every second in sound?
It depends how high the sound is, the a above middle C is 440Hz (vibrations/second) and there are 110Hz in an octave. From there you can work out the Hz of any note.
What sounds are above 20000 hertz?
Sounds above 20,000 Hz are considered ultrasonic and are inaudible to humans. Some animals, like bats and whales, can hear sounds in this frequency range. Ultrasonic sounds are commonly used in technology, such as electronic devices like ultrasonic cleaners.
What is Roman Numeral 20000?
20000=XX with horizontal bar above the 2X's.
What frequency of waves in the air can be heard as an audible sound by the human ear?
For the human ear, sound is audible in the range of 20 Hz (Hertz) to 20000 Hz. Sounds below 20 Hz are "infrasonic" and have too low a frequency to be heard; sounds above 20000 Hz are "ultrasonic" and are too high a frequency to be heard.
What is sounds with frequencies above 20000 Hz?
Sounds with frequencies above 20,000 Hz are considered ultrasonic and are generally not audible to the human ear. Some animals, such as bats and dolphins, are capable of hearing and producing sounds in this frequency range. Ultrasonic frequencies are also used in various technologies like medical imaging and pest control.
What is the range of vibrations per second to be able to produce sound?
The range of vibrations per second required to produce sound is typically between 20 Hz and 20,000 Hz for human hearing. Below 20 Hz is considered infrasound, and above 20,000 Hz is considered ultrasound.
A mountain peak in the Himalayas has an elevation of 20000 feet above see level if you climbed to the top would you be 20000 feet above the bse of the mountain?
No, the elevation of 20000 feet is measured from sea level, not from the base of the mountain. If you climb to the top of the mountain, you would be at the summit, but your elevation above the base of the mountain would be less than 20000 feet.
What is pitch of sound?
The pitch of sound refers to how high or low a sound is perceived. It is determined by the frequency of the sound waves, with higher frequencies producing higher pitched sounds and lower frequencies producing lower pitched sounds.
Sounds that are below the range of human hearing?
The sounds with frequency below the hearing range are named Infrasounds and the sounds with frequency above the hearing range are named Ultrasounds. I would say infrasonic . 20000
What can happen above 20000 Ft?
There can be a lack of air and you need an oxegen mask in order to breath well 20000 ft high
Why is sound low and high pitch?
Sound pitch is determined by the frequency of the sound wave. Low-pitched sounds have a lower frequency, with fewer vibrations per second, while high-pitched sounds have a higher frequency with more vibrations per second. The pitch of a sound is perceived by our ears based on the frequency of the sound wave.
