Mary is 21 years old. Her age is 9 years more than 3 times Henry’s age. Which equation can be used to determine x, Henry’s age in years?
Answers
Answer:4
Step-by-step explanation:
21=3x+9
12=3x
X=4
Final answer:
To find Henry's age, use the equation 21 = 3x + 9, where x represents Henry's age which is 4.
Explanation:
The question asks to find the equation to determine Henry's age. Given that Mary is 21 years old and her age is 9 years more than 3 times Henry's age, we set up the equation as follows: Let x represent Henry's age. The equation then becomes 21 = 3x + 9. This equation can be used to solve for x, Henry's age which is 12 = 3x; x = 4.

Sara had 207 dollars to spend on 9 books. After buying them she had 18 dollars. How much did each book cost
Answers
Answer:
21
Step-by-step explanation:
207-18=189..then divide by 9
The problem involves subtracting Sara's remaining money from her initial amount to find the total spent on books, then dividing by the number of books, giving us that each book cost 21 dollars.
Explanation:This is a basic algebra problem where we need to find the cost of each book. Sara initially has 207 dollars and after buying 9 books, she has 18 dollars left. Therefore, we can calculate the total spent on books by subtracting the final amount from the initial.
The calculation is: 207 dollars - 18 dollars = 189 dollars.
Now, to find the cost of each book, divide the total spent by the number of books. So, 189 dollars divided by 9 books results in 21 dollars per book.

Answers
In 1 pack there is 6 pencils cause you need to divide 36 by 6. In 3 packs there are 18 pencils because 6 pencils times 3 packs is 18 pencils!
Hope this helped!
Answer with step-by-step explanation:
We are given that there are 36 pencils in 6 packs and we are to find out how many pencils are there in one pack and three packs.
To find the number of pencils in one pack, we need to divide the number of pencils by the number of packs.
Number of pencils on 1 pack = 36/6 = 6 pencils
To find the number of pencils in 3 packs, we will multiply the number of pencils in one pack by 3.
Number of pencils in 3 packs = 6 * 3 = 18 pencils

Question 35
Any four vertices of a regular pentagon will form a parallelogram. This is because the internal angles and lengths are such that selecting any four vertices will always result in the formation of a closed, opposite sides being equal, and opposite angles being equal shape, which is a parallelogram.
Question 36
If two circles touch, the point of contact lies on a straight line. Hence, the correct answer is a straight line.
Question 37
The domain of the relation R where R = {(x,y): y = x + x ; x ≥ 0 and x < 9} will be as follows: we are given that y = x + x^2 and x ranges from 0 (inclusive) to 9 (exclusive). Thus, the possible values for x within these constraints are all integers from 0 to 8. Therefore, the correct domain is
{0, 1, 2, 3, 4, 5, 6, 7, 8} and correct option is d. None
Question 38
If Mary's share is Rs. 225 and it is divided between Mary and David in the ratio 3:2, we first find the portion that represents Mary’s share. Here, Mary’s share is 3 parts and David’s is 2 parts. Together, their shares add up to 5 parts. If 3 parts equate to Rs. 225, then 1 part is Rs. 75. The total amount of money, which is 5 parts, will be 5 * 75 = Rs. 375. Hence, the correct total is Rs. 375.
Question 39
The angle between the vectors 2î + 3ĵ + k and 2î - 3ĵ - k can be found using the dot product formula.
The dot product of A and B, A.B = |A| |B| cos θ. First, compute A.B:
A = 2î + 3ĵ + kB = 2î - 3ĵ - kA.B = (2)(2) + (3)(-3) + (1)(-1) = 4 - 9 - 1 = -6Next, find |A| and |B|:
|A| = √(([tex]2^2) + (3^2) + (1^2)[/tex]) = √(4 + 9 + 1) = √(14)|B| = √(([tex]2^2) + (-3^2) + (-1^2[/tex])) = √(4 + 9 + 1) = √(14)Therefore,
cos θ = A.B / (|A| |B|) = -6 / (√(14) × √(14)) = -6 / 14 = -3 / 7Taking the inverse cosine:
θ = [tex]cos^(-1) (-3 / 7)[/tex]The approximate answer to the angle is around 116 degrees. However, because most multiple-choice sets would give their answers in radians, you would need to adjust accordingly.

wll what is the value of y

C
D

155
Answers
Answer:
D
Step-by-step explanation:
10x - 5 and 7x + 4 are vertical angles and congruent, hence
10x - 5 = 7x + 4 ( subtract 7x from both sides )
3x - 5 = 4 ( add 5 to both sides )
3x = 9 ( divide both sides by 3 )
x = 3
7x + 4 and y are same side interior angles and are supplementary, thus
y + 7x + 4 = 180 ← substitute x = 3
y + 21 + 4 = 180
y + 25 = 180 ( subtract 25 from both sides )
y = 155 → D
if the pattern below follows the rule "starting with 10,every consecutive line has a number one less than the previous line." how many marbles must be in the sixth line?
Answers
I believe 5 marbles on the 6th line.
Line 1: 10
2: 10-1=9
3: 9-1=8
4; 8-1=7
5: 7-1=6
6: 6-1=5
For the pattern given, the number of marbles in the sixth line is 5.
Given that:
"Starting with 10, every consecutive line has a number one less than the previous line."
This is the pattern of the positions of the marbles.
The first line has 10 marbles.
The second line has 10 - 1 = 9 marbles.
The third line has 9 - 1 = 8 marbles.
The fourth line has 8 - 1 = 7 marbles
The fifth line has 7 - 1 = 6 marbles
The sixth line has 6 - 1 = 5 marbles.
The number of marbles in any line will be 10 - (n - 1) marbles for any nth line.
Hence the number of marbles is 5.

Given y = 4x + 3, what effect does changing the equation to y = 4x - 3 have on the y-intercept?
Answers
Answer:
The y-intercept changes from (0, 3) to (0, -3)
Step-by-step explanation:
The y-intercept refers to the point where the graph of a function crosses or intersects with the y-axis. At this point, the value of x is usually 0.
Substitute x = 0 in both equations to determine how the y-intercept changes;
The original equation is given as y = 4x + 3,
when x = 0; y = 4(0) + 3 = 3
The y-intercept is thus (0, 3)
The new equation is given as y = 4x - 3
when x = 0; y = 4(0) - 3 = -3
The y-intercept is thus (0, -3)
Therefore, the y-intercept changes from (0, 3) to (0, -3)

How do you find a area of a square?
Answers
Answer:
To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
The area of a square is length times width:
Area = length x width
^^^This is the same for a rectangle too
The only difference is that the length of all the sides of a square are equal to each other, so to find the area of a square you are essentially multiplying on side with it self

Answers
Answer: A; Linear, Strong
Step-by-step explanation: A linear scatterplot is normally when most of the dots on the scatterplot board are quite close to each other in a line. When it is strong it when most of the dots seem to form an actual line.
I hope this info helps!
A scatterplot categorized as "A: Linear, Strong" indicates a distinct and well-defined linear relationship, with closely clustered data points along the trend line, highlighting a robust association between the variables.
The correct answer is option A.
The scatterplot's visual characteristics provide insights into the nature of the relationship between two variables. In this case, when the answer is categorized as "A: Linear, Strong," it implies that the scatterplot predominantly exhibits a linear trend, suggesting a consistent and directional association between the variables. In a linear scatterplot, most data points align closely along a straight line, indicating a systematic relationship.
The term "strong" further emphasizes the degree of correlation or association between the variables. A strong linear scatterplot implies that the points are tightly clustered around the line, indicating a robust and noticeable relationship. The strength of the association is a reflection of how well the data points conform to the linear pattern, emphasizing the reliability of the trend observed.
In summary, when a scatterplot is described as "A: Linear, Strong," it signifies a clear and well-defined linear relationship between the variables, with data points forming a closely packed arrangement along the trend line.

Step-by-step explanation:
4C implies that we multiply each element in C by the constant 4.
12*4 = 48
0*4 = 0
(3/2)*4 = 6
This will be the new elements on top
1*4 = 4
-6 * 4 = -24
7 * 4 = 28
This will be the new elements at the bottom. The required matrix 4C is thus;
[tex]\left[\begin{array}{ccc}48&0&6\\4&-24&28\end{array}\right][/tex]
Answer:
The required matrix is:
[tex]4C=\left[\begin{array}{ccc}48&0&6\\4&-24&28\end{array}\right][/tex]
Step-by-step explanation:
The matrix given is:
[tex]C=\left[\begin{array}{ccc}12&0&3/2\\1&-6&7\end{array}\right][/tex]
We need to find 4C which means we need to multiply the matrix C with 4. Every entry of matrix will be multiplied by 4.
[tex]4C=\left[\begin{array}{ccc}4*12&4*0&4*3/2\\4*1&4*-6&4*7\end{array}\right][/tex]
Solving:
[tex]4C=\left[\begin{array}{ccc}48&0&12/2\\4&-24&28\end{array}\right]\\4C=\left[\begin{array}{ccc}48&0&6\\4&-24&28\end{array}\right][/tex]
