Answer:

D. The 7 in the thousands place is one hundredth the size of the 7 in the ten thousands place.

Step-by-step explanation:

The 7 in the thousands place is ten times greater than the 7 in the ten thousands place.

The relationship between the 7 in the thousands place and the 7 in the ten thousands place can be understood by their positions within the number. In a multi-digit number, each digit has a place value based on its position. The place value of a digit determines its worth. For example, the 7 in the thousands place is ten times greater than the 7 in the hundreds place, and the 7 in the ten thousands place is ten times greater than the 7 in the thousands place. Therefore, the 7 in the thousands place is ten times greater than the 7 in the ten thousands place.

We see that the measures given are Corresponding Angles

Step 2: Solve for x

Four triangles would be formed by drawing all the diagonals from a single vertex of a hexagon.

When all the diagonals are drawn from a single vertex of a polygon, the number of triangles formed depends on the number of sides of the polygon. To calculate the number of triangles, we need to use the formula:

number of triangles = (number of sides - 2)

For example, if we have a pentagon (a polygon with five sides), the number of triangles formed from a single vertex would be:

number of triangles = (5 - 2) = 3

So, three triangles would be formed by drawing all the diagonals from a single vertex of a pentagon.

Similarly, for a hexagon (a polygon with six sides), the number of triangles formed would be:

number of triangles = (6 - 2) = 4

6t = 360

t = 360÷6

t= 60°

Now,

The solution to the inequality is:

x ∈ (-√2, 3/4) ∪ (√2, 4).

What is inequality ?

An inequality is a mathematical statement that compares two values or expressions using symbols such as <, >, ≤, or ≥. It indicates that one value or expression is less than or greater than the other. Inequalities can be solved by using various algebraic techniques to find the range of values that satisfy the inequality. Inequalities are commonly used in many areas of mathematics, such as in algebra, geometry, and calculus, as well as in real-world applications such as economics, physics, and engineering.

According to the question:
To solve the inequality f(4x-3)/(2-x²)>0, we first need to find the critical values of x where the function is equal to zero or undefined.

For f(4x-3) to be zero, we have 4x-3 = 0, which gives us x = 3/4.

For 2-x² to be zero, we have 2-x² = 0, which gives us x = ±√2.

We also need to check where the function is undefined, which is where the denominator (2-x²) is equal to zero. This occurs at x = ±√2.

So, we have critical values at x = -√2, 3/4, and √2.

We can use a sign chart to determine the intervals where the function is positive.

x                     -√2    3/4 √2

f(x)

(4x-3)/(2-x²)        - + -

sign                  - + -

From the sign chart, we see that the function is positive on the intervals (-√2, 3/4) and (√2, 4). Therefore, the solution to the inequality is:

x ∈ (-√2, 3/4) ∪ (√2, 4).

Answer:

Let's use algebra to solve the problem.

Let x be the number of 50 cent pieces in the moneybox.

Then the number of 20 cent pieces in the moneybox is 600 - x (since there are 600 coins in total).

The value of x 50 cent pieces is 50x cents.

The value of (600 - x) 20 cent pieces is 20(600 - x) = 12000 - 20x cents.

The total value of the coins is the sum of these two values:

50x + (12000 - 20x) = 3000 + 30x

So there are 3000 + 30x cents in the moneybox.

To find the total number of cents, we need to evaluate this expression for x:

3000 + 30x

We don't know the value of x, but we do know that there are 600 coins in the moneybox, so we can set up another equation:

x + (600 - x) = 600

Simplifying this equation, we get:

x + 600 - x = 600

Simplifying further, we get:

600 = 600

This equation is always true, which means we can solve for x in terms of 600:

x = 600 - (600 - x)

x = 600 - (600 - x)

x = 600 - (600 - x)

x = 600 - 600 + x

x = x

So x can be any value between 0 and 600.

To find the total number of cents in the moneybox, we need to evaluate the expression 3000 + 30x for any value of x between 0 and 600.

The minimum value of this expression occurs when x = 0:

3000 + 30(0) = 3000

The maximum value of this expression occurs when x = 600:

3000 + 30(600) = 21000

So there are between 3000 and 21000 cents in the moneybox, depending on how many 50 cent pieces there are.

Answer: What number cards??

Step-by-step explanation:

Answer:

The letter t occurs more than 26 times on approximately 420 of these pages.

Step-by-step explanation:

1 standard deviation below mean = M - SD

                                                      = 44 - 18 = 26

This implies that that "26" is 1 s.d. below the mean, which is at the 16th percentile.

Thus,  there is a 0.16 chance that "t" will occur less than 26 times on any single page.

consequently, there is a 0.84 chance that it will occur more than 26 times on any single page.

Therefore, the distance between the two points is 13 units.

Distance is the measure of the length between two points or objects. It is the amount of space between two points, or the length of a path traveled by an object. Distance is typically measured in units such as meters, kilometers, miles, feet, or yards. In physics, distance is often used to describe the separation between two objects in space, and it is an important factor in many scientific calculations, such as speed, velocity,

and acceleration.

Here is the plot of the two points on the coordinate plane:

The statement "Construct a line from A perpendicular to the y-axis, determine the distance from A to the y-axis along this perpendicular line, find a new point on the other side of the y-axis that is equidistant from the y-axis" accurately describes how to reflect point A (3, -1) over the y-axis

To reflect a point over the y-axis, you need to find a new point that is the same distance from the y-axis as the original point, but on the other side of the y-axis.

This can be done by constructing a perpendicular line from the original point to the y-axis, determining the distance from the original point to the y-axis along this line, and then finding a new point on the other side of the y-axis that is the same distance from the y-axis as the original point.
