What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
The expression is given as;
13822 × 623 / 14
Now,
a. Solve the expression as;
13822 × 623 / 14 = 8,611,106 / 14
= 615,079
Thus, The exact value is 615079.
b. Reduce fraction to the lowest term by canceling the greatest common factor:
6911 × 89
Then, Calculate the product = 615079.
So, By using approximation to 1 significant figure we get 600000.

Answer:
x = 26
Step-by-step explanation:
The three angles form a straight line, so they will sum to 180
4x - 8 + 34 + 76- x = 180
Combine like terms
3x+ 102 = 180
Subtract 102 from each side
3x+102-102 = 180-102
3x= 78
Divide each side by 3
3x/3 = 78/3
x = 26

What is the 6th term in this geometric sequence? 5, -15, 45, -135
Answer:
-1215.
Step-by-step explanation:
For a geometric sequence:
nth term = a1 r^(n-1)
The first term a1 = 5 and the common ratio r = -15/5 = -3.
So 6th term = 5 * (-3)^(6-1)
= 5 * (-3)^5
= -1215.
The 6th term in this geometric sequence should be considered as the -1215.
Calculation of the 6th term:The following formula should be used for the same.
nth term = [tex]a_1\ r^{(n-1)[/tex]
Here,
The first term a1 = 5
and the common ratio r = [tex]-15/5[/tex]= -3.
So 6th term should be
[tex]= 5 \times (-3)^{(6-1)}[/tex]
[tex]= 5 \times (-3)^5[/tex]
= -1215
Hence, The 6th term in this geometric sequence should be considered as the -1215.

The given number line shows the solutions to which inequality?
A)
x + 7 ≤ 5
B)
x + 3 ≥ 1
C)
x − 5 > 2
D)
x − 1 ≤ 1
Answer:
A)
x + 7 < 5
Shows inequality
The correct inequality that represents the solutions on the given number line is C) [tex]\( x - 5 > 2 \).[/tex]
To find the correct inequality, we need to determine which one corresponds to the shaded portion of the number line. The shaded portion indicates the set of all [tex]\( x \)[/tex] values that satisfy the inequality.
Let's analyze each option:
A) [tex]\( x + 7 \leq 5 \)[/tex]
If we solve this inequality, we get:
[tex]\( x \leq 5 - 7 \)[/tex]
[tex]\( x \leq -2 \)[/tex]
This inequality would be represented by a number line shaded to the left of -2, including -2 itself. This does not match the given number line, which is shaded to the right of a point.
B) [tex]\( x + 3 \geq 1 \)[/tex]
Solving this inequality, we get:
[tex]\( x \geq 1 - 3 \)[/tex]
[tex]\( x \geq -2 \)[/tex]
This inequality would be represented by a number line shaded to the right of -2, including -2 itself. However, the inequality sign in the question is non-inclusive, which means -2 itself should not be shaded. This does not match the given number line, which has a shaded circle at the starting point of the shaded region, indicating inclusivity.
C) [tex]\( x - 5 > 2 \)[/tex]
Solving this inequality, we get:
[tex]\( x > 2 + 5 \)[/tex]
[tex]\( x > 7 \)[/tex]
This inequality would be represented by a number line shaded to the right of 7, not including 7 itself. This matches the given number line, which shows the shaded region starting just to the right of 7 (indicated by an open circle at 7).
D) [tex]\( x - 1 \leq 1 \)[/tex]
Solving this inequality, we get:
[tex]\( x \leq 1 + 1 \)[/tex]
[tex]\( x \leq 2 \)[/tex]
This inequality would be represented by a number line shaded to the left of 2, including 2 itself. This does not match the given number line, which is shaded to the right of a point and has an open circle at the starting point of the shaded region.
Therefore, the correct answer is C)[tex]\( x - 5 > 2 \)[/tex], as it accurately describes the shaded region on the given number line.
What is the slope between the points (0,–5) and (–9,1)?
The slope between the points (0, –5) and (–9,1) is -2/3, which is found using the slope formula. Positive slopes rise, negative slopes fall, and zero slopes are horizontal lines.
Explanation:To find the slope of a line passing through two points (0, –5) and (–9,1), we use the formula for the slope (m), which is m = (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.
Substituting the given points into the formula, we get m = (1 - (-5)) / (-9 - 0), which simplifies to m = (1 + 5) / (-9), and further simplifies to m = 6 / (-9), resulting in a slope of m = -2/3.
Regarding slope and its characteristics on a graph, a positive slope means the line rises as it moves from left to right, a negative slope means the line falls as it moves from left to right, and a zero slope indicates a horizontal line.
WZ = 5.3 km, find the area of the shaded sectors to the nearest tenth. Please help
Answer: The area of the shaded sectors is 35.3 square kilometres
Step-by-step explanation: What we have here is a circle with center Z. Two sectors have been formed which are ZVW and ZYX. A careful observation reveals that both sectors are similar. If WY passes through the center Z then WY is a diameter. The same applies to VX, since it also passes through the center, therefore it is a diameter. Both lines intersect at the center, that makes both sectors to have the same radii which is 5.3 km and same applies to the angle subtended at the center of the sector, both angles are opposite angles formed by intersecting lines (opposite angles formed by intersecting lines are equal). On a straight line WY, the sum of angles ∠WZX and ∠YZX equals 180 degrees (Sum of angles on a straight line equals 180). Therefore;
WZX + YZX = 180
108 + YZX = 180
Subtract 180 from both sides of the equation
YZX = 72°
Therefore the area of shaded sector YZX is given as;
Area of a sector = (∅/360) x πr²
Where ∅ is 72, and r is 5.3
Area of sector = (72/360) x 3.14 x 5.3²
Area of sector = 0.2 x 3.14 x 28.09
Area of sector = 17.64
Having in mind that both sectors are similar (the same radii and the same central angle), the area of the shaded sectors shall be equal to 17.64 times 2 and that equals 35.28. (That is approximately 35.3 to the nearest tenth)
The area of the shaded sectors therefore is 35.3 square kilometres (35.3 km²)
Answer:
Area of the shaded region ≈ 35.3 km²
Step-by-step explanation:
Area of a sector = ∅/360 × πr²
angle on a straight line = 180°
Therefore,
∠vzw = 180 - 108 = 72°
∠yzx = 180 - 108 = 72°
Area = 72 /360 × 22/7 × 5.3²
Area = 72 /360 × 22/7 × 28.09
Area = 44494.56/2520
Area = 17.656571429
Area = 17.66 km²
The area is one portion of the shaded part , the area of the 2 shaded sector will be
Area of zvw + Area of zyx
Both area are same . They have same radius and the same angle.
Area of the shaded region = 17.66 + 17.66
Area of the shaded region ≈ 35.3 km²

Answer:
49x^2 - 9 = 0
As there is no x term, we can pretty much guess we have a situation where we factlrise by something known aa difference of two squares, so to factorise it:
49 = 7^2
9 = 3^2
x^2 = (x)^2

the pictures aren't loading but i think we have the same problem if this is on edge, b is a straight line that passes through the origin, a c and d do not line up
The graph of ordered pairs that shows a proportional relationship is: Graph 1
How to Identify the proportional relationship?A proportional relationship is defined as a relationship between two variables where the ratio of the variables is always the same. In other words, one variable is always a constant multiple of the other variable.
Graph 1: The rate of change of y with x for the two points are:
m = -2/1 = -2
m = -4/2 = -2
Graph 2: The rate of change of y with x for the two points are:
m = 3/1 = 3
m = -2/-2 = 1
Graph 3: The rate of change of y with x for the two points are:
m = -2/1 = -2
m = 1/-3 = --1/3
Graph 4: The rate of change of y with x for the two points are:
m = 1/2
m = 3/5
Thus, the only one that represents a proportional relationship is Graph 1

(If you are using MathsWatch) For this question the triangle gets smaller so i'm not sure why it says Enlarge the triangle.
To enlarge the triangle by a scale factor of 0.5 with a center of enlargement at (3,1), multiply the coordinates of each vertex by 0.5 and add 3 to the x-coordinate and 1 to the y-coordinate.
Explanation:To enlarge the triangle by a scale factor of 0.5 with a center of enlargement at (3,1), you will need to multiply the x-coordinate and y-coordinate of each vertex of the triangle by 0.5 and then add 3 to the x-coordinate and 1 to the y-coordinate. This will give you the new coordinates for the enlarged triangle. For example, if the original triangle has vertices A(1,2), B(3,4), and C(5,6), the new coordinates for the enlarged triangle will be A'(3.5,2.5), B'(4.5,3.5), and C'(5.5,4.5).
