Hello, your answer is: <span>1079, because remember, this equation represents
*800 - (-279)
so, you need to use the method of KCC, or, k=keep, c=change, c=change.
you keep the 800 positive, switch the (-) subtraction sign to a (+) addition sign, and also, make the (-279) a positive 279. so you turn out with:
*800 + 279, which equals = 1079

If the object hit the ground, then this mean that the height is 0, right?
so solve for it like this:
0= -16t^2+144
-144 = -16t^2
Divide by (-16)
9= t^2
square root both sides
t= 3 or -3
there is no negative time then the object will hit the ground after 3 secs

Answer: 50, 75 and 100 (2:3:4) for a total of 225
Step-by-step explanation:
2+3+4 = 9
Each can be expressed as a fraction:
2/9
3/9
4/9
(2/9 + 3/9 + 4/9 = 1)
2/9 * 225 = 50
3/9 * 225 = 75
4/9 * 225 = <u>100</u>
225
