Helen [10]

Answer:

5/9, 11/18, 2/3, 13/18, 7/9, 15/18

Step-by-step explanation:

To find the number between these 2, see what is between it:

to see the number between 1/2 and 8/9, we have to:

Times 1/2 by 9 times = 1/2 * 9 = 9/18

Times 8/9 by 2 times = 8/9* 2 = 16/18

So the number between 9/18 and 16/18 would be"

10/18, 11/18, 12/18, 13/18, 14/18, 15/18

Simply some of that, we got:

5/9, 11/18, 2/3, 13/18, 7/9, 15/18

Andre runs for 35 seconds at a velocity of -8 meters per second. He is running west. What is his finishing position?

user100 [1]

Answer:

d = -280 m

Step-by-step explanation:

Given that,

Velocity of Andre, v = -8 m/s

Time taken, t = 35 seconds

We need to find his finishing position. Let the finishing position be x.

We know that,

Velocity = distance/time

So,

$d=v\times t\\\\d=-8\times 35\\\\=-280\ m$

so, he was at a distance of 280 m in west.

I think the mistake is the third step is 3/4x+1/2x then you have to find the common denominator which 4 so next they would have to do 3/4x + 4/4x which is 7/4x
