Considering the graph of the velocity of the car, it is found that the interval in which it was stopped at a traffic light was:
Between 3 and 4 minutes.
<h3>When is a car stopped at a traffic light?</h3>
When a car is stopped at a traffic light, the car is not moving, that is, it's velocity is of zero.
In this problem, the graph gives the <u>velocity as a function of time</u>, and it is at zero between 3 and 4 minutes, hence the interval in which it was stopped at a traffic light was:
Between 3 and 4 minutes.

Answer:
Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.
Step-by-step explanation:
Let the number of red beads be x, then the number of yellow beads is 50 - x.
Then, 6/9 = x/(50 - x)
9x = 6(50 - x) = 300 - 6x
15x = 300
x = 300/15 = 20
Therefore, we expect 20 red beads in the bag.
Answer:
0.85 m
Step-by-step explanation:
0.68/8=A decent of 0.085 miles per 0.1 minute
So per minute 0.085x10 =0.85, our plane will have a change of 0.85 m in altitude
