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}

Please someone help me‼️
Flauer [41]

Answer:

6 m

Step-by-step explanation:

The volume of a cone is found by \frac{\pi r^2h}{3}, so we can plug the values in to get 6pi * r^2 / 3 = 72pi, or 6pi * r^2 = 216 pi, so r^2 = 36 and the radius is 6 m.

Which table might represent ava's line ?
Serjik [45]

Answer:

The correct option is 3.

Step-by-step explanation:

To find the slope of a line Ava wrote the expression

m=\frac{4-2}{3-1}       ..... (1)

The formula to find the slope is

m=\frac{y_2-y_1}{x_2-x_1}            .... (2)

On comparing (1) and (2), we get

x_1=1, y_1=2

x_2=3, y_2=4

It means the value of y is 2 at x=1 and the value of y is 4 at x=3.

Therefore table 3 represents the Ava's line and option 3 is correct.
