kherson [118]

Given:
land area of Alaska: 1,700,000 square kilometers
land area of Florida: 0.10 of Alaska

To find the land area of Florida, we multiply its decimal to the land area of Alaska

1,700,000 sq. km * 0.10 = 170,000 square kilometers.

The land area of Florida is 170,000 square kilometers. It is equal to 0.10 or 10% of the land area of Alaska.<span />

Select the two values of x that are roots of this equation 3x^2 + 1 =5x

Zina [86]

Answer:

x = 1.434 and x=0.232

Step-by-step explanation:

To find the root of the equation stated above we need to:

(1) Write the polynomial equation with zero on the right hand side:

$3x^{2} + 1 = 5x$ ⇒ $3x^{2} -5x + 1 = 0$

(2) Divide the whole equation by 3

$3x^{2} -5x + 1 = 0$ ⇒ $x^{2} -\frac{5}{3}x + \frac{1}{3}= 0$

(3) Use the quadratic formula to solve the quadratic equation:

The quadratic formula states that the two solutions for a quadratic equation is given by:

$\frac{-b±\sqrt{b^{2} - 4ac}}{2a}$ (1)

In this case, a = 1, b = $-\frac{5}{3}, c= \frac{1}{3}$

Substituiting a, b and c in equation (1) We get:

$\frac{-\frac{5}{3}±\sqrt{(-\frac{5}{3})^{2} - 4(1)(\frac{1}{3})}}{2(1)}$ (1)

The two solutions are:

x = 1.434 and x=0.232

faust18 [17]

Answer:

Step-by-step explanation:

Let the numbers of steps you can take to reach your goal be x

Your goal is to take at least 10,800 steps per day and you have walked 7370 steps already.

x + 7370 >= 10800

x >= 10800 - 7370

x >= 3430
