When graphs are plotted, graphs as in the .jpeg image in attachment are obtained.
First graph is line going through ordered pair (point) (0,6) and pair (6,8).
The second graph is line going through ordered pair (6,8) and pair (8,0).
Intercept of these graphs is point (ordered pair) (6,8).
You see from the .jpeg image that the following is true:
Initial velocity of the runner is 6 meters per second (runner starts with this velocity), for a while he runs, velocity grows, then in the 6th second (time=6), runner starts to slow down and velocity starts to decrease, and runner stops totally at time = 8.
So runner stops after 8 seconds.
The 4th claim (sentence) is correct.

54.8 m= ? km? how did you solve? do you place the zeros in front or behind the number? where does my decimal go and why does it

Maru [420]

M is smaller than km
1000m=1km

so divide by 1000
basically move decimal 3 places to left
put zero in front
0.0548km

You know that the rose garden is 20% of the total garden. What is 20% written as a ratio?

astraxan [27]

Answer:

20:100

Step-by-step explanation:

We know that percentages are out of 100. The rose garden is 20 percent of the garden. Which is 20 percent/100 percent. A ratio says how much of one thing there is compared to another thing. Therefore we are comparing 20:100. You can also simplify this ratio to 1:5
