Answer:
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2)
Answer:
9m+4n+5
Step-by-step explanation:
9m
19 - 14 = 5
4n
so we can combined the 9m,5,4n to 9m+4n+5
If both machines are working at once, 200 tshirts (100 in each machine) could be made in 100 minutes, if 200 shirts can be made in machine 1 in 50 minutes, it will take 25 minutes to make 100. machine b takes 150 minutes per each 200, 150 divided by two is 75. 75 + 25 = 100 minutes
It would work better just to use machine one and take 50
minutes, but i dont think thats an answer choice.
edit: i think from the choices your answer would be: 37.5 as if both machines run at once more tshirts can be made
so.. whatever "x" is, we know 1125 + x = y
and whatever the alcohol concentration yield may be, we know
(1125)(0.9) = 0.75y
(1125)(0.9) = 0.75y <--- solve for "y", that's how much the final amount of milliliters will be
how much pure water was added? subtract 1125 from that, or y - 1125
