the answer is A
Step-by-step explanation:
1 • 0.4 = 0.4
2 • 0.2 =0.4... 0.2+0.2=0.4
1 3/4 hours* (2/3)= 1 1/6 hours.
They spent 1 1/6 hours studying insects~
The zeros are (x+4)(x-4)(x+6)(x-3).
Speed = distance/time
Speed = 90 meters/45 seconds
Simplify the above answer
Speed = 2 meters/second
You can double-check this: You walk 2 meters per second, so multiply 2 by 45 (that is how many seconds), and you get 90.
