Luna is making a rope ladder. Each step of the ladder is 2 1/3 feet wide and uses an additional 1/2 foot on each end of the step
koban [17]

By taking the quotient between the total length and the length needed for each step, we conclude that Luna can make 9 steps.

<h3>How many steps can she make from the rope?</h3>

To find this, we need to take the quotient between the total length of the rope and the length needed for each step.

She has a total length of 30ft.

For each step she needs (2 + 1/3) ft plus (1/2) ft for each knot, and there are two knots, then each step needs: (2 + 1/3)ft + 2*(1/2)ft = (3 + 1/3) ft.

Then the number of steps that can be made is:

N = (30 ft)/(3 + 1/3) ft. = 9

She can make 9 steps or the lader.

Solve the equation 2x^2-3x-6=0 give your answer correct to two decimal places
IRISSAK [1]

Answer:

<h2>x = - 1.14 or x = 2.64</h2>

Step-by-step explanation:

2x² - 3x - 6 = 0

Using the quadratic formula

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

a = 2 , b = - 3 , c = 6

Substituting the values into the above formula

We have

x =  \frac{ -  - 3± \sqrt{ { - 3}^{2}  - 4(2)( - 6)} }{2(2)}

x =  \frac{3± \sqrt{9 +48 } }{4}

x =  \frac{3± \sqrt{57} }{4}

x =  \frac{3 -  \sqrt{57} }{4}  \:  \:  \:  \: or \:  \:  \:  \:  \: x =  \frac{3 +  \sqrt{57} }{4}

We have the final answer as

<h3>x = - 1.14 or x = 2.64</h3>

Hope this helps you
