The of 90000 is 9000.
We have a number - 90000
We have to determine part of this number.
The part of 100 will be -
= 20
According to the question, we have -
Number - 90000
Therefore, 1/10 of 90000 will be -
= 9000
Hence, of 90000 is 9000.

Answer:
the tablet was $2.99
Step-by-step explanation:
A.
y = 3.15x + 79.48
B.
y = 79.48x + 3.15
C.
y = 79.48x - 3.15
D.
y = 3.15x - 79.48
The correct equation to determine the amount of money Craig earned yesterday is 'y = 3.15x + 79.48', where 'y' is the total money earned, '3.15' is the hourly wage, 'x' is the number of hours worked, and '79.48' is the total tips.
The subject of the question is a mathematical problem related to real-world applications of linear equations. In this problem, Craig earns a fixed number of dollars per hour, $3.15, plus a fixed amount of tips, $79.48. These two groups of money create his total earnings for the day. Therefore, the equation to represent this relationship should reflect this fact by multiplying the number of hours he works, represented by 'x', by his hourly wage, and then adding his total tips.
Therefore, the correct equation is: y = 3.15x + 79.48, where 'y' represents the total amount of money Craig earned yesterday. In this equation, '3.15x' represents Craig's earnings from his hourly wage, and '79.48' represents his tips.

Answer:
Quadratic equations have the solution
x = [-b +-sqr root(b^2 -4ac)] / 2a
In the given equation a = l; b = m and c = n So,
x = [-m +-sqr root(m^2 -4*l*n)] / 2*l
