Hi,
8 Pckts each has 500 g weight .Total weight would be 8*500=4000g
and she arranged them into 3 boxes.
assume those three boxes are X,Y,Z first,second,thrid respectively.
X+Y+Z=4000g--------------------1
then according to the statement first box is twice heavy as second one
means X=2Y----------------2
and thrid box is 60g heavier than second box.
Z=Y+60--------------------3
put those values in to eq 1
2Y+Y+Z=4000
3Y+Y+60=4000
4Y=4000-60
4Y=3940
Y=985
second box weight is 985 gram
V30% mixture + v100% mixture = v60% mixture
0.3(10-x) + x = 0.6(10)
3 - 0.3x + x = 6
0.7x = 6 - 3
0.7x = 3
x = 3/0.7
x = 4.286 quarts
I think it’s c but i’m not sure just make sure about that because the line below the greater than symbol means something but i forgot what it means just g00gle it :]
Answer:
numbers less than 5 are 1,2,3,4 and equal to 5 is 5.
probability of less than 5 is 4/16
while equal to 5 is 1/16
or means additions; so its 4/16 +1/16=5/16
Both side multiply by one number.
