○ + ○ + ○= 30
○ + ¤¤ + ¤¤= 18
¤¤ - ☆☆= 2
☆ + ○ × ¤= ?
○ =10
¤¤ = 4 so ¤ =2
☆☆= 2 so ☆ = 1
○ + ○ + ○ = 10 + 10 + 10 = 30 ...correct
○ + ¤¤ + ¤¤ = 10 + 4 + 4 = 18 ...correct
¤¤ - ☆☆ = 4 - 2 = 2 ...correct
☆ + ○ × ¤= 1 + 10 x 2 = 21

Answer: C.) 1.12 seconds
Step-by-step explanation:
Hi, to answer this question we have to substitute h=0 (when the rock hits the ground the height above it is 0) in the equation given:
h (t) = –16t2 + 20
Solving for t (time)
0= –16t2 + 20
16t2=20
t2=20/16
t=√1.25 =1.12 seconds (option C)
