Answer:
The rate of Yvone's hair growth is 3.1 cm per month.
Step-by-step explanation:
WIth the data from Yvonne's hair we can create a sequence that goes as follows:
A = {47, 50.1, 53.2, 56.3, 59.4,...}
This is an arithmetic sequence, the numbers are related to each other by a common difference, in other words to find the next number we just need to add a constant "r". To find this constant we can subtract any adjacent numbers on this sequence, this is shown below:
r = 50.1 - 47 = 3.1
r = 53.2 - 50.1 = 3.1
r = 56.3 - 53.2 = 3.1
and so on.
The rate of Yvone's hair growth is 3.1 cm per month.
Given :
Tickets cost $3 for students and $5 for adults.
A total of 125 people attended the concert for a total ticket sales of $475.
To Find :
The number of students and adults that attended the concert.
Solution :
Let, number of students and adults that attended the concert is x and y.
Mathematical equation of given conditions :
x + y = 125 ....1)
3x + 5y = 425 ....2)
Putting value of x from 1 to equation 2 is :
3( 125 - y ) + 5y = 425
375 - 3y + 5y = 425
2y = 50
y = 25
x = 125 - 25
x = 100
Therefore, number of students and adults that attended the concert is 100 ans 25 respectively.
Hence, this is the required solution.

Answer:
answer
Step-by-step explanation:
The proper answer to this question is "21378.6".
Reason:
2.13786 *10^4
(3.2*10^4) first, then (1.4*10^2)
(3.2*10000)*1.4*100
32000*140
4480000
