What is 490% written as a decimal?

1 answer:

5 0

If we first convert it to a fraction, we get 490/100. Now if we actually do 490 ÷ 100, we get 4.9, which is the answer. I hope this helps!

Pemfaktoran dari 2x²+5x-18<br><br>

Harrizon [31]

We can factor a polynomial by finding its roots. In particular, a quadratic equation has (at most) two roots $x_1,\ x_2$ , which would allow us to write the polynomial as

$p(x)=a(x-x_1)(x-x_2)$

To find the solutions, we can use the quadratic formula

$x_{1,2} = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a} = \dfrac{-5\pm\sqrt{169}}{4} = \dfrac{-5\pm13}{4}$

So, the two solutions are

$\dfrac{-5+13}{4} = 2\quad\text{and}\quad\dfrac{-5-13}{4} =-\dfrac{9}{2}$

And so we can factor the polynomial as follows:

$2x^2+5x-18=2(x-2)\left(x+\dfrac{9}{2}\right)$

Answer:

The measure of angle x is 50 degrees

Step-by-step explanation:

we know that

$x+y=90$ ----> equation A

$x=2y-30$ ----> equation B

solve the system by substitution

substitute equation B in equation A

$(2y-30)+y=90$

solve for y

$3y=90+30$

$3y=120$

$y=40^o$

Find the measure of angle x

$x=2(40)-30=50^o$

therefore

The measure of angle x is 50 degrees
