Answer: 24
Step-by-step explanation:
Amount of bushels of peas collected = 42
Fraction that'll be sent to market = 3/7
Fraction that'll be kept = 1 - 3/7 = 7/7 - 3/7 = 4/7
The number of bushels that'll be kept will be:
= Fraction that'll be kept × Total number of bushels collected
= 4/7 × 42
= 24
12A+8W > 343 represents the number of minutes the robot filters air A and water W to filter more than 343 liters of air and water.
If the robot filters air for 20 minutes and water for 15 minutes, plugging A as 20 and W as 15, let us check if the equation is true or not.
Checking left side:
12A + 8W = 12(20) +8(15)
240+ 120 = 360
Checking right side: 343
12A+8W > 343
360>343
True.
So the robot meets the first expectation.
Let us check for second equation:
3A+4W < 49
Left side : 3A +4W = 3(20) +4(15) = 60 +60 =120
Right side is 49
comparing left and right side:
3A+4W < 49
120<49
False.
So the robot does not meet the second expectation.
