Convert 2.25 into decimal form

Mathematics
2 answers:
Marta_Voda [28]3 years ago

Is 2.25 is already in decimal form, right? If you want to change 2.25 percent in decimal form, the answer will be 0.0225 because you just need to divide 2.25 with 100 to get the answer which is 0.0225. Hope it help!

It is 0.0225 because p<span>ercentage means 'out of 100 100 '. Convert the </span>decimal<span> number to a fraction by shifting the </span>decimal<span> point in both the numerator and denominator. Since there are 2 2 numbers to the right of the </span>decimal<span> point, move the </span>decimal<span> point 2 2 places to the right.</span>

Write the quadratic equation whose roots are 3 and -5, and whose leading coefficient is 2.
Rainbow [258]

\begin{cases} x=3\implies &x-3=0\\ x=-5\implies &x+5=0 \end{cases}\qquad \implies\qquad a(x-3)(x+5)=\stackrel{0}{y} \\\\\\ a(\stackrel{F~O~I~L}{x^2+2x-15})=y\implies \stackrel{\textit{leading coefficient of 2}}{2(x^2+2x-15)}=y\implies 2x^2+4x-30=y

-1.8 - 6x = 6(0.1 + 3x)
Wittaler [7]

Answer:

x = -1/10 or -0.1

Step-by-step explanation:

-1.8 - 6x = 6(0.1 + 3x)

-1.8 - 6x = 0.6 + 18x

-6x - 18x = 0.6 + 1.8

-24x = 2.4

-x = 2.4/24

-x = 24/10 / 24

-x = 24/10 * 1/24

-x = 24/240

-x = 1/10

x = -0.1
