Answer: -6. 4. -3,75. 37.
Step-by-step explanation: -20|+10-2²= -6, since a minus×minus give you a + therefore -2²=4.
2³+(-8)= 12-8=4, a minus×plus gives you a minus.
-2,50+(-1,25)=-2,50-1,25=-3,75. |-10|+|20|-5²-(-2)=-10+20+25+2=37.
In order to answer this question, we use the concept of ratio and proportion wherein we use the equation,
R1 / T2 = R2 / T1
where R is for rate and T is for time. Substituting the known values to the equation,
(600)/x = (400)/ 20
The value of x from the equation is 30. Thus, it will take 30 hours if the rate was adjusted to 400 gallons per minute.
