Answer:
Step-by-step explanation:
a. it takes 9 minutes for the robot to complete one task
b. In one hour then robot can complete 6.7 tasks however since you reallly cant quantify .7 tasks the robot can only complete 6 tasks
To answer this, we let x some factor that would agree or make the ratio given true. We calculate as follows:
<span>2:3:4
2x:3x:4x
2x = 12
x = 6
Therefore, the length of the longest side would be 4x = 4(6) = 24 cm, third option.</span>
Answer: 82
Step-by-step explanation:
We simply need to substitute the values for x and y into the equation
Both variables are already given to us, x=9, y=2
8(9)+2+4(2)
72+2+8
