Answer:
A, D, F
Step-by-step explanation:
6(3b+4)=18b+24
6(3b+8)=18b+48
2(96-12)=192-24
3(6b+8)=18b+24
3(6b+4)=18b+12
2(9b+12)=18b+24
Step-by-step explanation:
The formula to find the final velocity, v of an object having an initial velocity , u , and acceleration , a , at time t is v=u+at
(a) v=u+at
Subtract u from both sides,
v-u=u+at-u
v-u=at
Dividing both sides by t.
(b) The relationship between the acceleration and time for a given initial and final velocity is given by "
Where
s is the distance covered
t is the time
Hence, this is the required solution.
Answer:
Step-by-step explanation:
Most tracks are 400 meters around, as measured in Lane 1; that's just a bit less than one-quarter of a mile. Here are some other measurements that it's helpful to know: 100 meters: the length of one straightaway. 800 meters: roughly ½ mile or 2 laps around the track
good luck, hope this helped
Answer: 31.5
Step-by-step explanation:
9 is 100% so if you times that by 3 you get 27 and 50% of 9 is 4.5 if you add that to 27 you get 31.5
