A truth table is a way of organizing information to list out all possible scenarios. We title the first column p for proposition. In the second column we apply the operator to p, in this case it's ~p (read: not p). So as you can see if our premise begins as True and we negate it, we obtain False, and vice versa.
In 2000, 7689 weekly papers = 94% of number of weekly papers in 1960
Let weekly papers in 1960 be x.
7689 = 94% of x
7689 = (94/100)*x
7689 * 100/94 = x
8179.787 ≈ x
x ≈ 8179.787
Number of weekly newspapers in 1960 rounded to the nearest whole number = 8180
The answer is 176.44
9,800
Answer:
B: T = ½R
Step-by-step explanation:
From the given graph, we see the following;
When T = 2, R = 4
When T = 3, R = 6
When T = 4, R = 8
When T = 5, R = 10
Looking at those values, we can see a pattern where R is always equal to 2T.
Or T = ½R
Thus, option B is the answer.
Answer:
The equation is C, and the correct answer is 6 (D)
Step-by-step explanation:
We first look for the correct equation. If Matt charges 9 dollars per hour, and earned a total of 99, then we known that 9*the number of hours = 99. Moving on, we know that he babysat Friday night for 5 hours, but we don't know the number on Saturday. BUT we do know that 5+saturday hours = total number of hours. Putting this into a formula, we get 9(5+x (where x = #of hours worked on saturday) = 99(total number)
Our final equation is 9(5+x)=99.
Solving this by dividing both sides by 9, we get 5+x=11. Subtracting 5 from both sides gives us x = 6.
