Answer:
1, 42
Step-by-step explanation:
Another pair of factors of 42 would be 2, 21. Factors, when multiplied, would get 42. 6,7 would also work, etc etc.
Answer:
The correct answer is $16500 and $ 10000 each in two accounts.
Step-by-step explanation:
Samantha invests a total of $26,500 in two accounts.
Let Samantha invest $x in one account and $(26500 - x) in the other account.
The first account earned a rate of return of 14% (after a year).
Return earned = 14% of x
The second account suffered a 4% loss in the same time period.
Loss suffered = 4% of (26500 - x)
At the end of one year, the total amount of money gained was $1,910.00.
Therefore 14% of x - 4 % of (26500 - x) = 1910
⇒ 0.14x - 1060 + 0.04x = 1910
⇒ 0.18x = 2970
⇒ x = 16500
Therefore Samantha invested $16500 and $10000 each in two accounts.
U can name an angle three ways
1. you can name an angle by the letters like this (ABC,DFG)
2.you name it by using the vertex
3. you name it by the placing of a number or letter in the angle
Now the aim of the above discussion is to internalize the mathematical relationships for open-end air columns in order to perform calculations predicting the length of air column required to produce a given natural frequency. And conversely, calculations can be performed to predict the natural frequencies produced by a known length of air column. Each of these calculations requires knowledge of the speed of a wave in air (which is approximately 340 m/s at room temperatures). The graphic below depicts the relationships between the key variables in such calculations. These relationships will be used to assist in the solution to problems involving standing waves in musical instruments.
