  price/(24 oz) = $1.90/(16 oz)

Multiplying by 24 oz, we get ...

  price = $1.90(24/16) = $2.85

Enter the correct answer in the box. solve the equation x2 − 16x 54 = 0 by completing the square. fill in the values of a and b
poizon [28]

The roots of the given polynomials exist  $x=8+\sqrt{10}$, and $x=8-\sqrt{10}$.

<h3>What is the formula of the quadratic equation?</h3>

For a quadratic equation of the form $a x^{2}+b x+c=0$ the solutions are

$x_{1,2}=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Therefore by using the formula we have

$x^{2}-16 x+54=0$$

Let, a = 1, b = -16 and c = 54

Substitute the values in the above equation, and we get

$x_{1,2}=\frac{-(-16) \pm \sqrt{(-16)^{2}-4 \cdot 1 \cdot 54}}{2 \cdot 1}$$

simplifying the equation, we get

$&x_{1,2}=\frac{-(-16) \pm 2 \sqrt{10}}{2 \cdot 1} \\

$&x_{1}=\frac{-(-16)+2 \sqrt{10}}{2 \cdot 1}, x_{2}=\frac{-(-16)-2 \sqrt{10}}{2 \cdot 1} \\

$&x=8+\sqrt{10}, x=8-\sqrt{10}

Therefore, the roots of the given polynomials are $x=8+\sqrt{10}$, and

$x=8-\sqrt{10}$.

A company policy requires that for every 30 employees, there must be 3 supervisors. If there are 267 supervisors at the company,
Alexus [3.1K]

267 supervisors will have 2670 employees.

Step-by-step explanation:

Let x be the number of employees.

Given,

3 supervisors = 30 employees

1 supervisor = \frac{30}{3}

1 supervisor = 10 employees

As one supervisor has 10 employees, 267 supervisors will have;

x = 267*10

x= 2670 employees

267 supervisors will have 2670 employees.
