Answer:
Of two numbers, The largest whole number which is a factor of both.
Step-by-step explanation:
hi
-16t²+250 = 75
-16t² = 75 -250
-16t² = -175
t² = -175 /-16
t² = 175/16
Here there si two solutions : t =
and t = - 
However, as time cannot rewind, we will keep only positive solution
So t = 
in seconds it will be : 3.3 seconds

Answer:
Step-by-step explanation:

Answer:
sin Φ/(sin Φ + cos Φ) = 12/17
Step-by-step explanation:
sin Φ = 12/13
then sin Φ + cos Φ = 12/13 + 5/13
= 17/13
So , sin Φ/(sin Φ + cos Φ) = 12/13 ÷ 17/13
= 12/13 × 13/17
= 12/17
