I believe the correct answer would be that it has one solution which is 5. Calculating x for the quadratic equation, you will only get one value so it should be one solution. Hope this answers the question. Have a nice day.
One way to do this problem is to take 26.65 and divide it by all of the values from $2.01 to $2.99. If one of these goes in evenly with no remainder then that is the cost of each notepad. The quotient (answer when you divide) is the number of pads. Since we can’t have half a pad, the number must go in evenly (leave no remainder).
While we can check each of these, I noticed that 26.65 ends in a 5 and so is divisible by 5 so I decided to check 2.05 as a possible price and it went in evenly. The quotient is 13.
thus, there were 13 notepads and the cost of each is $2.05
The international company has 46864 employees in total.
<u>Step-by-step explanation:</u>
Given that,
An international company has 12,700 employees in one country.
And, this 12,700 employees represents 27.1% of the company's employees.
Therefore, the total number of employees can be found by calculating the 100% of the employees.
Let us assume that the total number of the employees be 'x'.
From the x number of employees, 12,700 employees were 27.1%
<u>Now, framing the above statement in the equation form to solve for x :</u>
⇒ 27.1 % of x = 12700
⇒ (27.1 / 100) x = 12700
⇒ 0.271 x = 12700
⇒ x = 12700 / 0.271
⇒ x = 46863.5 (which is approximately 46864 employees)
Therefore, the total number of employees is 46864.
Ok so maybe add or subtract the numbers and see what u get :) I calculated it
A suitable calculator finds the determinant to be ...
... B. -203
_____
This can be calculated by hand by copying the first two columns to the right of the given matrix, then forming the sum of products of the downward diagonals and subtracting the sum of products of the upward diagonals.
... (-4)(3)(-5) +(-4)(-5)(-5) +(-3)(3)(2) -(-5)(3)(-3) -(2)(-5)(-4) -(-5)(3)(-4)
... = 60 -100 -18 -45 -40 -60
... = -203
