The answer is A!
-4.82, -4(2/3) = - 4.667, sqrt 15 is 3.873, 4.15, 465% is 4.65, and 1.5pi =4.65
Hope this helps!
Answer and Step-by-step explanation:
C(x) be the statement "x has a cat"
D(x) be the statement "x has a dog"
F(x) be the statement "x has a ferret".
Universe = x = all students in your class.
a) A student in your class has a cat, a dog and a ferret
= ∃x(C(x) ∧ D(x) ∧ F(x))
b) All students in your class have a cat, a dog, or a ferret = ∀x(C(x) ∨ D(x) ∨ F(x))
c) Some students in your class has a cat and a ferret but not a dog = ∃x (C(x) ∧ F(x) ∧ ¬D(x))
d) No student in this class has a cat, a dog and a ferret ¬∃x (C(x) ∧ D(x) ∧ F(x))
e) For each of the three animals, cats, dogs and ferrets, there is as student in your class who has one of the three animals. (∃xC(x)) ∧ (∃xD(x)) ∧ (∃xF(x))
Answer:
Step-by-step explanation:
5. The problem gives us that the dollar value of the quarters we have is v, and the number of quarters we have is n. So basically, for example, if n was 8 then v would be 2 because there are 4 quarters in every dollar, so 8 quarters would be 2 dollars. Thus, to find how many dollars in the amount of quarters you have, you must divide by 4. Therefore, the equation would be v = 1/4n.
6. To be honest, I don't know what number 6 is asking. It's asking for Output $, but to find the output, you must have an input, but the problem doesn't give you one. It might be cropped out so, if the problem gives you an input (in this case, n quarters), you divide it by 4 and that will be your answer to 6. (ie. the problem gives you 12 as the input. Answer would be 3 because 12 quarters = 3 dollars).
If it doesn't give you the input, then I believe it would be 0.25 because each quarter is 0.25 of a dollar. I believe it should have an input number though, because it doesn't make any sense to me.
7. The independent variable is the thing you are changing, or the input. Since the number of the quarters is the input and not the VALUE of the quarters, it is false.
Answer:
Step-by-step explanation:
145+15x>490. subtract 145 from both sides
15x>345, divide both sides by 15
x>23
