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!

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 = 
x 0 3 6
y 14 9 4
Point of intersection of these lines will be (6, 4).
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:

This implies that:

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