Add up all the sides and you get 10
The distance between Car A and car B,When Car A crosses the start line is:
distance =speed car B* time
distance=(15 m/s)(3 s)=45 m
Distance traveled by car A =x, (when the car B is at the same distance from the start line)
time of car A=t
x=10 m/st ⇒ x=10t (1)
Distance traveled by car B=x
time of car B=t-3
x=15(t-3) (2)
With the equations (1) and (2) we make a system of equations:
x=10t
x=15(t-3)
We solve this system of equations:
10t=15(t-3)
10t=15t-45
-5t=-45
t=-45 / -5
t=9
t-3=9-3=6
x=10 t=10 (9)=90
Answer: The time would be 9 seconds for Car A and 6 seconds for car B and the distance would be 90 meters.
Answer:
sure there is
Step-by-step explanation:
SSS means side side side so if 3 of the sides on each triangle are the same then its congruent Any time you see an A it stands for angle so you only have to learn the leters and then everything else is pretty straight forward
Answer:
7047, people/km^2
Step-by-step explanation:
To find the answer, you would need to divide the numbers 8550405(people) and 1213.4(kilometers) <--- which where this came from.
Once you divide those numbers, you will directly get the number 7047 as your answer.

Answer:10
Step-by-step explanation:
2+4+6+.....+20- (1+3+5+7+...+19)=(2-1)+(4-3)+(6-5)+....+(20-19)=1+1+...+1 ( de 10 ori= 10 times)
=10
