Answer:
So the annual percent of decay is: 7.77%
Step-by-step explanation:
If the value of a car was $18000 in 2006, and in 2016 it was worth $4000 it means, it lose 77.77% of its value in 10 years.
To calculate the percentage of decay we use the rule of three:
If the price of the car in 2006 ($18000) represents 100%, then, how much does $4000 represents?
4000*100/18000 = %22.22
Now, we know that $4000 represents 22.22% the original value, so it lose 100% - 22.22% = 77.77% of its value.
So the annual percent of decay is: 77.77% / 10 = 7.77%
Answer:
length= 3.7 ft.
Step-by-step explanation:
T= (square root of length) * k
1.8 seconds = (square root of 3) * k
k= 1.8 seconds / (square root of 3)
a.) T= (square root of 11) k
substituting k:
T=(square root of 11) * 1.8 seconds / (square of 3)
T= 3.4 seconds
b.) 2 seconds = (square root of length) k
substituting k:
2 seconds =(square root of length) 1.8 seconds / (square root of 3)
Divide the equation by 1.8 seconds / (square root of 3):
2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)
10(square root of 3) / 9 = (square root of length)
square both sides:
100/7 ft= length
length= 3.7 ft.
Hope this helps.
Step-by-step explanation:
as a whole number = 5
Answer:
<2 and <13 are alternate exterior angles.
In simple form, alternate exterior angles are the opposite angle on the opposing parallel line. So, to make you understand better, <4 and <15 are alternate exterior angles.
Hope this helps :D
