You are biking to the park. After six minutes 40% of the distance still need to be traveled. How long does it take to bike to th
nikklg [1K]

Answer:

y = (100-10x)\%

It takes <em>10 minutes</em> to the park.

Step-by-step explanation:

Given that:

Time taken = 6 minutes

Distance left to be traveled = 40%

To find:

The equation to represent the distance y, that still needs to be traveled after x minutes.

Solution:

As per given statement, distance traveled in 6 minutes = 60%

We can say that:

Distance traveled each minute = \frac{60\%}{6} = 10%

After 1 minute, distance traveled = 10%

Distance left = 100 - 10 = 90%

After 2 minutes, distance traveled = 20%

Distance left = 100 - 20 = 80%

After x minutes, distance traveled = 10x%

Distance left, y = (100 - 10x)%

Therefore, the equation is:

y = (100-10x)\%

Time taken by the bike to reach to the park can be found by putting y = 0 (i.e. distance left to be traveled = 0)

0 = 100 -10x\\\Rightarrow 10x = 100\\\Rightarrow x = \bold{10\ minutes}

Let f(t) be the the number of units produced by a company t years after opening in 2005. What is the correct interpretation of f
Crazy boy [7]

Answer:

In 2011, 44,500 units are produced

Step-by-step explanation:

Let

t ----> the number of years after 2005

f(t) ----> the number of units produced by a company

we have

f(6)=44,500

so

For t=6, f(t)=44,500

That means

The number of units produced by a company is  equal to 44,500 units six years after 2005

so

six years after 2005 is the year 2011

therefore

In 2011, 44,500 units are produced
