Answer:
6
Step-by-step explanation:
first let's find all the possible combinations excluding 6+6 to get 12 using addition, we exclude 6+6 because we can't have the same integer for different variables. these are 0+12, 1+11, 2+10, 3+9, 4+8, and 5+7(also the other way around but i start with these). using common sense, I started higher because there is no way d = 0 and e= 12, so i went from 5+7 down. through trial and error and some luck, 5+7 was the correct combination. let's insert the numbers with their variables. d = 5 and e = 7. now we figure out, what minus 5 is 7? if you learned fact families in kindergarten, you'd know to find this out you add 5+7, which is 12. now we divide 12 by 2, because it's the same number added together to get this number, so you now get 6+6. does the equation make sense? (6+6) - 5 = 7, that checks out, and 5+7=12.

DUE TODAY!! LINEAR FUNCTIONS
What is an equation for the linear function whose graph contains the points (−1,−2) and a slope of 3?
Enter your answers in the boxes.
y+ ? = ? (x+1)
Answer:
The point-slope form of the equation of a line is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. In this case, we have a point (-1,-2) and a slope of 3. Substituting these values into the equation, we get:
y - (-2) = 3(x - (-1))
Simplifying this equation, we get:
y + 2 = 3(x + 1)
So, the equation for the linear function whose graph contains the point (-1,-2) and has a slope of 3 is y + 2 = 3(x + 1).

Brainlist for positive attitude and correct answer :D
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

( True / False ) Force is used in aristocracy government.
If yes, how?
If no, why?
Answer:
True
Step-by-step explanation:
Looking at this topic generally force is used, if we look at the different countries across Europe at the beginning of civilization, there is lot of usage of force by the Aristocratic Governments. Even though it was prominent in Europe, there were also traces of it during the rule of Shang and Zhou dynasties of China. To support the citizens force is required, in the ancient times, use of force to make citizens obey the laws is a common practice. Nowadays in these countries the elite members who control the country reap the benefit and use of force is just to get themselves the money. Nowadays its all about Money.
False, because in aristocracy you are not forced to participate in the government.

7. If the height of a rectangle is 8.8 m and the base is 7.9 m, what is the perimeter of the rectangle
8. If the base of a rectangle is 23cm and the area is 354 cm2, what is the height of the rectangle?
9. What is the area of a square with a perimeter of 44 mm?
10. What is the area of a square with a perimeter of 55 cm
Answer:
Step-by-step explanation:
To find the area of a parallelogram, multiply the base by the height:
Area = base x height
Area = 6.3 m x 27.3 m
Area = 171.99 m²
To find the height of a rectangle, divide the area by the base:
Height = Area / Base
Height = 420.92 mm² / 27.4 mm
Height ≈ 15.35 mm
The perimeter of a rectangle is given by 2 times the sum of the base and height:
Perimeter = 2(base + height)
133.2 mm = 2(30.6 mm + height)
133.2 mm = 61.2 mm + 2 height
2 height = 133.2 mm - 61.2 mm
2 height = 72 mm
Height = 72 mm / 2
Height = 36 mm
To find the height of a parallelogram, divide the area by the base:
Height = Area / Base
Height = 645 m² / 61 m
Height ≈ 10.57 m
The perimeter of a parallelogram is the sum of all its sides:
Perimeter = 2(base + side length)
Perimeter = 2(32 cm + 34 cm) + 2(height)
Perimeter = 2(66 cm) + 2(19 cm)
Perimeter = 132 cm + 38 cm
Perimeter = 170 cm
To find the area of a parallelogram, multiply the base by the height:
Area = base x height
Area = 40 mm x 18 mm
Area = 720 mm²
The perimeter of a rectangle is given by the formula: Perimeter = 2(base + height)
Perimeter = 2(7.9 m + 8.8 m)
Perimeter = 2(16.7 m)
Perimeter = 33.4 m
To find the height of a rectangle, divide the area by the base:
Height = Area / Base
Height = 354 cm² / 23 cm
Height ≈ 15.39 cm
The perimeter of a square is 4 times the length of one side. Since the perimeter is given as 44 mm, we can divide it by 4 to find the length of one side:
Side length = Perimeter / 4
Side length = 44 mm / 4
Side length = 11 mm
To find the area of a square, multiply the side length by itself:
Area = side length x side length
Area = 11 mm x 11 mm
Area = 121 mm²
The perimeter of a square is 4 times the length of one side. Since the perimeter is given as 55 cm, we can divide it by 4 to find the length of one side:
Side length = Perimeter / 4
Side length = 55 cm / 4
Side length = 13.75 cm
To find the area of a square, multiply the side length by itself:
Area = side length x side length
Area = 13.75 cm x 13.75 cm
Area ≈ 189.06 cm²

You have a deck of cards and draw three cards one after the other without replacing the cards. What is the probabilities of drawing three tens? (Pls give a good explanation & the answer lol)
Answer:
The probability of drawing 3 tens one after another without replacing them is 1/5525
Step-by-step explanation:
In a pack of 52 cards, there are 4 cards that are 10, so the probability of drawing one ten [p(10)] = 4/52
Therefore:
The first draw, P(10) = 4/52
Now, at this point you have taken out one of the cards with a number 10 printed on it, so we are left with 51 cards in total and 3 cards of 10.
The second draw, p(10) = 3/51
Now, we have 50 cards left and a total of 2 cards with a number 10 printed on it.
The third draw, p(10) = 2/50
Hence, the probability of drawing out 3 number 10 cards without replacement is:
4/52 * 3/51 * 2/50 = 1/5525
The probability of drawing 3 tens one after another without replacing them should be 1/5525.
Calculation of the probability:Since we know that
In a pack, there are 52 cards and there are 4 cards that are 10,
so the probability of drawing one ten [p(10)] = 4/52
Now it should be left with 51 cards in total and 3 cards of 10.
So, The second draw, p(10) = 3/51
and, The third draw, p(10) = 2/ 50
Thus, the total probability is
= 4/52 * 3/51 * 2/50
= 1/5525

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x

Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)
Find the 24th term.
-9, 0, 9, 18, 27, ...
24th term = [? ]
Answer:
198
Step-by-step explanation:
Answer: 198
Step-by-step explanation:
Firstly, you must find the nth term.
the sequence is: -9, 0, 9, 18, 27, ...
find the difference between each term. in this sequence, the difference is 9, so it is 9n
then you must find the difference between the sequence 9n and this sequence. 9n is:
9, 18, 27, 36, 45, ...
now find the difference between 9n and our sequence.
adjustment = -18
so the nth term is 9n - 18
now you need to substitute 24, as that is the term you would like to find out, in place of n.
so, our n term looks like this: 9(24)-18
9 x 24 = 216
216 - 18 = 198
hence, the answer is 198.
hope this helps.
