Answer: 10.3 s
Step-by-step explanation:
Given
The height of the arrow is given by 
At
and 
When arrow hits ground, h becomes 0 i.e.

Neglecting the negative value of t
So, the arrow hits the ground after 10.30 s
Step-by-step explanation:
1.
4:15 p.m. to 5.00 p.m. → 45min
5:00 p.m. to 10:00 p.m. → 5h
Answer: 5h 45min
2.
3:45 a.m. to 4.00 a.m. → 15min
4.00 a.m. to 12:00 p.m. → 8h
Answer: 8h 15min
3.
1:15 p.m. to 2:00 p.m. → 45min
2:00 p.m. 8:00 p.m. → 6h
8:00 p.m. to 8:11 p.m. → 11min
Answer: 6h (45 + 11)min = 6h 56min
4.
2:37 a.m. to 3:00 a.m. → 23min
3:00 a.m. to 3:15 a.m. → 15min
Answer: (23 + 15)min = 38min
5.
11:59 a.m. to 12:00 p.m. → 1min
12:00 p.m. to 1:00 p.m. → 1h
1:00 p.m. to 1:01 p.m. → 1min
Answer: 1h (1 + 1)min = 1h 2min
Any number greater than 9
Remember you can do anything to an eqution as long as you do it to both sides
easy
first one
flat rate+variable rate=amount paid
flat rate=35
variable=15 times hours, so if h=hours then
and amount paied is 95
35+15h=95 is da equation
if we solve
mins 35 both sides and divide both sides by 15
h=4
2nd one
add 5 to both sides and times 4 both sides
c/4=9
c=36
3rd photo
add 6 to both sides
y+6-6≥12+6
y+0≥18
y≥18
