Answer:
(5.33 + 2h) ≥ 7
h ≥ 0.835
Step-by-step explanation:
Let in the last two days Julian has to practice the drum for h hours each.
Then in two days, he has to practice 2h hours,
He has already practiced 
hours before those last two days.
Therefore, he has practiced this week by (5.33 + 2h) hours.
Now, given that Julian needs to spend at least 7 hours each week practicing the drums.
Hence, we can write the inequality
(5.33 + 2h) ≥ 7
⇒ 2h ≥ 1.67
⇒ h ≥ 0.835 hours
Therefore, Julian has to practice for 0.835 hours for the last two days of the week. (Answer)
So men to women=3 to 4
210 men
210 represents 3 units
wome=4
210=3 units
divide by 3
70=1 unit
multiply by 4 to find women
280=women
total workers=women+men
women=280
men=210
280+210=490
total =490
Answer:
See steps below
Step-by-step explanation:
Let F(x, y) and W be
F(x,y) = “x can fool y”
W the set of all the people in the world
a) <u>Everybody can fool Fred.</u>
b) <u>Evelyn can fool everybody.</u>
c) <u>Everybody can fool somebody.</u>
d) <u>There is no one who can fool everybody</u>.
e) <u>No one can fool both Fred and Jennifer.</u>
f) <u>Nancy can fool exactly two people.</u>
The correct answer would be C., I believe, because you take the opposite of the coordinate and subtract one. Hope this was helpful! (:
