There are 12 inches in a foot. When you convert 12 into millimeters, it becomes 304.8.
Hello,
N is closed for an opération(µ) means that
a,b ∈ N : a µ b ∈N (i suppose so)
Answer (1) ex 2/3 ∉ N
Answer (4) ex 2-3 ∉ N
∀ a,b ∈ N: a+b ∈N is true ; not a answer.
∀ a,b ∈ N: a*b ∈N is true ; not a answer.

The inequality would be
0.75q ≥ 0.70(q+1)
q is defined as the number of questions he answers after the first one. We are told he gets 75% of those correct; 75%=75/100=0.75. This gives us 0.75q.
Since he gains proficiency on the exercises, the total number he gets correct has to be at least 70%. This means the inequality would have the symbol greater than or equal to, as it cannot be less and have him gain proficiency.
He has already answered 1 question and answers q more; this gives us a total of q+1. Since he gains proficiency, the cutoff was 70%; 70%=70/100=0.70. This gives us the expression 0.70(q+1).
Our total inequality would then be 0.75q ≥ 0.70(q+1)
Answer:
Y=5X-7
Step-by-step explanation:
(2,3)
Y-Yo=m(X-Xo)
Y-3=m(X-2)
Y-3=mX-2m
Y=mX-2m+3
(5,18)
18=m(5)-2m+3
18=5m-2m+3
18=3m+3
18-3=3m
15=3m
15/3=m
5=m
Y=5X-2(5)+3
Y=5X-10+3
Y=5X-7
