mariah owed her grandfather $2.25 but was only able to pay him back 1.50 , how much does mariah currently owe her grandfather

aleksandr82 [10.1K]

Answer:

0.75 cents

Step-by-step explanation:

You take...

$2.25 and subtract $1.50 to get 0.75 cents

In-depth...

Start off with taking a dollar away...

2.25 - 1.00 = 1.25

Then take off 0.50 cents...

We know that 0.50 cents are two 0.25 cents

So, we take off one 0.25 cent

1.25 - 25 = 1.00

Then the next 0.25 cents

*Remember: twenty-five (.25), fifty (.50), seventy-five (.75), a dollar (1.00)

<--- it is just adding 25 each time

If we subtract 0.25 cents from a dollar we get...

0.75 cents

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth.

likoan [24]

Answer:

Thus, the two root of the given quadratic equation $x^2+4=6x$ is 5.24 and 0.76 .

Step-by-step explanation:

Consider, the given Quadratic equation, $x^2+4=6x$

This can be written as , $x^2-6x+4=0$

We have to solve using quadratic formula,

For a given quadratic equation $ax^2+bx+c=0$ we can find roots using,

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$ ...........(1)

Where, $\sqrt{b^2-4ac}$ is the discriminant.

Here, a = 1 , b = -6 , c = 4

Substitute in (1) , we get,

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$\Rightarrow x=\frac{-(-6)\pm\sqrt{(-6)^2-4\cdot 1 \cdot (4)}}{2 \cdot 1}$

$\Rightarrow x=\frac{6\pm\sqrt{20}}{2}$

$\Rightarrow x=\frac{6\pm 2\sqrt{5}}{2}$

$\Rightarrow x={3\pm \sqrt{5}}$

$\Rightarrow x_1={3+\sqrt{5}}$ and $\Rightarrow x_2={3-\sqrt{5}}$

We know $\sqrt{5}=2.23607$ (approx)

Substitute, we get,

$\Rightarrow x_1={3+2.23607}$ (approx) and $\Rightarrow x_2={3-2.23607}$ (approx)

$\Rightarrow x_1={5.23607}$ (approx) and $\Rightarrow x_2=0.76393}$ (approx)

Thus, the two root of the given quadratic equation $x^2+4=6x$ is 5.24 and 0.76 .
