7. If you run a half marathon (21 km) in 2 hours 6 minutes, how much tirne does it take you to run one kilometre?​
kupik [55]

Answer:

6 minutes per kilometer

Step-by-step explanation:

[] First, let's get one unit. I will be using minutes;

2 hours 6 minutes = 120 mintues + 6 mintues = 126 mintues

[] There are about 21 kilometers in a half-marathon;

126 minutes / 21 kilometers = 6 minutes per kilometer

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

What goes on the lines I don’t understand the problem
Elis [28]

Answer:

Step-by-step explanation:

a). Let the number of spoons = x

And number of forks = y

Total number of spoons and forks bought by Perry = 10

x + y = 10 --------(1)

Cost of one spoon = $5

Cost of one fork = $3

Therefore, total cost of x spoons and y forks = $(5x + 3y)

5x + 3y = 42 -------(2)

b). Now we can convert these equations into the slope-intercept form.

x + y = 10 ⇒ y = -x + 10

Table for input output values,

x        2         4          6          

y        8         6          4                

5x + 3y = 42

3y = -5x + 42

y = -\frac{5}{3}x+14

x        0           3          6        

y       14           9          4                  

Point of intersection of these lines will be (6, 4).

The height, h metres, of a particle at time, t seconds is given by the function:
vfiekz [6]

Answer:

It depends on what you are asked to do. See explanation.

Step-by-step explanation:

The height, h metres, of a particle at time, t seconds is given by the function:

h=(14-t)(t-2).

This means that after a given time, we can use this function to find the height of the particle.

For instance after 3 seconds, the height of the particle will be:

h=(14-3)(3-2)

This implies that:

h=11*1=11m

So after 3 seconds the height of the particle is 11 meters.
