An object accelerates from rest with a constant acceleration of 7.5m/s^2. How fast will it be traveling after it goes 87m?

Below

Explanation:

To find the final velocity Vf of an object you can use this formula :

     Vf = √Vi^2 + 2ad

          = √0m/s^2 + 2(7.5m/s^2)(87m)

          = 36.1247 m/s

The final velocity of this object is 36 m/s

Hope this helps! Best of luck <3

i guess it’s a and b

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
