explain truth tables and how they work
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 science class, students are mixing water and a citric acid solution. The table shows how much water and acid solution two students use. Whose mixture is more acidic?
Answer:
the one with the most parts citric acid
Step-by-step explanation:
no tables were provided but if a cup is 3/4 water and 1/4 citric acid and the other is 1/4 water and 3/4 citric acid then it's the second one. Basically it the one with the most citric acid.

Find the area of the circle with a diameter of 12 m.
a 95.64 m2
b 112.27 m2
C 113.04 m2
d 210.36 m2
Answer:
113.04 is our answer
Step-by-step explanation:
When finding Area the formula to do so is
radius x radius x pi
Sense we arent given radius we have to find out whats the radius but we must remember radius is just half of the diameter so since we are given diameter we will just do diameter divided by 2 so 12 ÷ 2 = 6 now that we have are radius we square it thats just a fancy way of saying multiply by itself so 6 x 6 = 36 now we multiply 36 with 3.14 So
3.14 x 36 = 113.04 So c is our answer!
A tax exempt employee benefit is usually more adavantages to the employee than a tax deferred benefit
Answer:
Step-by-step explanation:
Yes, it is, more or less. This is because with a tax-deferred account, tax savings are gotten when you make contributions, but when it then comes to a tax-exempt account, the withdrawals are instead free of tax during retirement.
In a tax-deferred account, you can make immediate tax deductions as much as the full amount of your intended contribution, but then, subsequent withdrawals from the same account will be taxed at the normal income rate.
On the other hand, tax-exempt accounts don't deliver a tax benefit, particularly when you contribute to the them, they provide tax benefits that comes much later

Two small planes leave Sacramento and LA, which are 380 miles apart, and travel toward each other. If one plane travel 30 miles per hour faster than the other plane and they meet in one hour, what are their respective speeds?
Thank you, thank you, thank you!!
Let the speed of the first plane be x then the speed of the second plane would be x + 30
The combined speed is x + x + 30 = 2x + 30
2x + 30 = 380
Subtract 30 from both sides
2x = 350
Divide both sides by 2
X = 175
The speed of the first plane was 175 miles per hour the speed of the second plane was 205 hour

4 is 2% of what number
Answer:
200
Step-by-step explanation:
Step 1: If 2% of a number is 4, then what is 100% of that number? Setup the equation.
4
2%=Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get:
2Y = 4 x 100
2Y = 400
Y = 400
100 = 200

From the code key, we can see that each number represent the alphabet at that position;
To do this, we simply replace each number with the alphabet they represent.
So, we have:
16-11-13-5-10 => P-K-M-E-J
2-15-18 => B-O-R
13-23 = > M-W
8-11-17 => H-K-Q

Answer:
Opaque
Step-by-step explanation:
Translucent materials, like greaseproof paper and frosted glass, let some but not all light through. They scatter or diffuse the light. Most materials do not allow light through at all and these are called opaque. (The second question is light)
Answer:
opaque, Radiant
Step-by-step explanation:
Opaque can not be seen through and radiant is an energy that can travel through space.
Item 11
A 10-foot ladder leans against a wall so that it is 6 feet high at the top. The ladder is moved so that the base of the ladder travels toward the wall twice the distance that the top of the ladder moves up. How much higher is the top of the ladder now? (Hint: Let 8−2x be the distance from the base of the ladder to the wall.)
Answer:
4 ft higher
Step-by-step explanation:
Since the ladder is 10 ft long and its top is 6 feet high(above the ground), we find the distance of its base from the wall since these three (the ladder, wall and ground) form a right angled triangle. Let d be the distance from the wall to the ladder.
So, by Pythagoras' theorem,
10² = 6² + d² (the length of the ladder is the hypotenuse side)
d² = 10² - 6²
d² = 100 - 36
d² = 64
d = √64
d = 8 ft
Since the ladder is moved so that the base of the ladder travels toward the wall twice the distance that the top of the ladder moves up.
Now, let x be the distance the top of the ladder is moved, the new height of top of the ladder is 6 + x. Since the base moves twice the distance the top of the ladder moves up, the new distance for our base is 8 - 2x(It reduces since it gets closer to the wall).
Now, applying Pythagoras' theorem to the ladder with these new lengths, we have
10² = (6 + x)² + (8 - 2x)²
Expanding the brackets, we have
100 = 36 + 12x + x² + 64 - 32x + 4x²
collecting like terms, we have
100 = 4x² + x² + 12x - 32x + 64 + 36
100 = 5x² - 20x + 100
Subtracting 100 from both sides, we have
100 - 100 = 5x² - 20x + 100 - 100
5x² - 20x = 0
Factorizing, we have
5x(x - 4) = 0
5x = 0 or x - 4 = 0
x = 0 or x = 4
The top of the ladder is thus 4 ft higher
The school that Shawna goes to is selling tickets to a spring musical. On the first day of ticke sales the school sold 7 adult tickets and 7 student tickets for a total of $91. The school took ir $170 on the second day by selling 14 adult tickets and 12 student tickets. Find the price of an adult ticket and the price of a student ticket.
Answer:
price of an adult ticket = a = $7
price of a student ticket = s = $6
Step-by-step explanation:
price of an adult ticket = a
price of a student ticket = s
7a + 7s = 91 (1)
14a + 12s = 170 (2)
Multiply (1) by 2
7a + 7s = 91 (1) × 2
14a + 14s = 182 (3)
14a + 12s = 170 (2)
Subtract (2) from (3) to eliminate x
14s - 12s = 182 - 170
2s = 12
s = 12/2
s = 6
Substitute s = 6 into (1)
7a + 7s = 91 (1)
7a + 7(6) = 91
7a + 42 = 91
7a = 91 - 42
7a = 49
a = 49/7
a = 7
price of an adult ticket = a = $7
price of a student ticket = s = $6
