The quadratic formula is $\frac{-b+-\sqrt[2]{b^2-4ac}}{2a}$

and in the equation ax^2+bx+c=0

so now all you have to do is substitute the numbers into the quadratic formula

What is 17/20 - 4/15

Zinaida [17]

Hello there, today you gave us the problem $\frac{17}{20}-\frac{4}{15}$ ,

Our first step is to give them common denominators, which is $\frac{51}{60}-\frac{16}{60}$ , solve it and we get $\frac{35}{60}$ as our answer, which can be simplified down to $\frac{7}{12}$

Lakelyn is training for a triathlon she is practising her swiming running and biking skills so far she can swim at a rate of 250

Nezavi [6.7K]

Answer:

The answer to the question is

It would take Lalelyn bout 3 hours to run the 18m miles, and it will take her

$\frac{x}{1.7} +\frac{y}{6} +\frac{z}{12} = t$ and x +y+z =18 where x, y, and z are the distannce covered swimming, running and bikinr respectifully

Step-by-step explanation:

To solve the question, we lisrt out the variables as follows

Swimming speed of Lakelyn = 250 yards every 5 minutes or 250×12 = 3000 yards/hour = 1.7 miles/hr

Running speed of Lakelyn = 6 miles/hour

Biking speed = 12 miles/hour

The duration it will take for Lakelyn to run 18 miles is given by

Timee taken to run 18 miles t = (Distance covered)/ (Speed of Lakelyn))

or t = D/S

Substituting the known values of such as

Running speed of Lakelyn = 6 miles/hour

From which we have the time taken to run 18 miles = 18 miles /(6 miles/hour) = 3 hours

should the 18 miles form part of the triathlon then, we have

$\frac{x}{1.7} +\frac{y}{6} +\frac{z}{12} = t$ and x +y+z =18

Where x, y and z are the distance covered Swimming, Running and Biking respectively
