WORTH 58 POINTS HELP MEE PLEASE

4:1

sorry if i'm wrong

Step-by-step explanation:

54 ÷6= 9

the first one is  5:1

then take away 9

45- 9 = 36

36:9 = 4:1

y = 1609 ft

Step-by-step explanation:

g is equal to 9,8 m/s²     or 32,18 ft/s²

According to g = 32,18 ft/s²

In the first second      as  y = -1/2 g*t²

y  = 1/2 32,18*(1)²       ⇒  y  = 16,9 ft           we dismiss the sign we know the object is falling down. Is enough for the purpose of this question

The second one

y  = 1/2* (32,18)* (2)²

y = 32,18*2          ⇒    y = 64,36 ft

third second

y = 1/2*32,18*(3)²     ⇒  y  = 144,81 ft

And in the  tenth second

y =( 1/2)* 32,18 * (10)²      ⇒    y = 1609 ft
