white ratio as a rate with a denominator of 1 2,400 copies in 3 minutes
Answer
Rate = 800 copies per minute
Explanation
Work = rate x time
Work = 2400 copies
Time = 3 minutes
Rate = work / time
Rate = 2400 / 3
Rate = 800 copies per minute

A rotation of 270 degrees counterclockwise is the same as a rotation 90 degrees clockwise.
This rotation will make a point from the first quadrant go to the fourth, from the second to the first, from third to second and from fourth to third.
If the point goes from the first quadrant to the fourth, we change the signal of the x-coordinate.
If the point goes from the second quadrant to the first, we change the signal of the y-coordinate.
If the point goes from the third quadrant to the second, we change the signal of the x-coordinate.
If the point goes from the fourth quadrant to the third, we change the signal of the y-coordinate.
Also, in all those rotations, we need to switch the x and y coordinates between themselves.

If it is "> or," the shaded arrow is drawn to the right of the inequality graph; if it is "or," it is drawn to the left.
Given the inequality, -1/2m ≥ 7/11,
Which represents the solution to one-half m is greater than or equal to negative seven elevenths
Solve for m:
⇒ -1/2m(-2) ≥ 7/11(-2)
m ≤ -14/11 [Because we are multiplying both sides by a negative value, the sign shifts]
The solution to the inequality is m ≤ -14/11 which the graph is attached below for m ≤ -14/11.

The inequality compound is:
[tex]3Answer: 3 < x < 5Sarah got a $60 gift card to Walmart. She uses the gift card to buy orange juice for $4.50. She also wants to use the gift card to buy shirts. Each shirt costs $2.29. Write an inequality to describe this situation, where n is the number of shirts Sarah wants to buy?Please answer quick, will give 18 points
ANSWER
[tex]4.50+2.29n\le60[/tex]EXPLANATION
We have that Sarah got a $60 gift card to use in Walmart.
This means that everything she can buy cannot be worth more than $60 (i.e. less than or equal to $60).
She buys orange juice for $4.50 and she wants to buy shirts (which cost $2.29 each)
Let n be the number of shirts Sarah wants to buy.
This means that the cost of n shirts is $2.29n.
Recall that she can only spend less than or equal to $60. This means that the sum of the cost of the orange juice and n shirts is less than or equal to $60.
That is:
[tex]4.50+2.29n\le60[/tex]That is the inequality that represents the situation.
Find the area of the figure.
Based on the given figure, the area of the figure can be found to be 126.50 cm²
How to find the area?The figure given is a mix of a triangle and a rectangle. The area of the figure can then be found by finding the area of the triangle and the rectangle individually, and then summing them up.
The area of a rectangle is:

Graph the line with the given slope that passes through the given point.
(a) slope:
3
4
,
point:
(1, 5)
The linear equation can be written as:
y = (3/4)*x + 17/4
And the graph can be seen at the end.
How to graph the linear equation?
A general linear equation is of the form:
y = m*x + b
Where m is the slope and b is the y-intercept.
Here we have the slope m = 3/4, so we get:
y = (3/4)*x + b
And the line passes through (1, 5), replacing these values in the equation we get:
5 = (3/4)*1 + b
5 - 3/4 = b
20/4 - 3/4 = b
17/4 = b
So the linear equation is:
y = (3/4)*x + 17/4
To graph the line we need other point, if we use x = 0 we get:
y = (3/4)*0 + 17/4 = 17/4
Then we have the points (1, 5) and (0, 17/4).
To graph the line, we just need to find these two points and connect them with a line, the graph can be seen below.

What do we call the total area of all exposed surfaces of a geometric solid?
The total area of all exposed surfaces of a geometric solid is called surface area .
What does it mean by surface area of geometric solid ?The area is the entire amount of space filled by flat or two-dimensional objects. In other words, the number of square units that cover the surface of a closed figure is used to represent its area.
It is quantified in square inches, or square units. The area only has length and width since 2-dimensional shapes can be measured using them.
The area is a two-dimensional measurement of the size of a flat surface, whereas surface area is a measurement of a solid shape's exposed surface (three-dimensional).
The main distinction between area and surface area is this. However, both amounts are expressed in square units, which is the same for both. Learn the distinction between area and volume as well.

Describe a series of transformations Matt can perform to device if the two windows are congruent
Congruent shapes are produced by combining the three different transformations—rotations, reflections, and translations. Actually, by combining one or more of these three transformations, any pair of congruent shapes can be matched to one another.
What are transformations?A point, line, or geometric figure can be transformed in four different ways, each of which alters the shape and/or placement of the object. While Image refers to the position and ultimate shape of the object, Pre-Image refers to the shape of the thing as it was before alteration.
Given Data
We now understand that the size and shape of the figures are preserved during stiff transformations (reflections, translations, and rotations). The pre-image and the actual image concur all the time.
The following Matt's transformational skills:
Reflection
Since the reflection maintains its original shape, The line of reflection remains the same distance away from comparable points from the pre-image to the image.
As a Congruence Transformation, rotations
Rotating a figure causes it to twist. Even though the figure is the same size and shape as before, it appears to have toppled over. A clock is a fantastic example of how the earth actually rotates. Every hour or every day, the clock's connecting arms revolve around their axis. A rotation's degree determines what it is, and common rotations include 90, 180, and 270 degrees. Before going back to its original position, the figure rotates a full 360 degrees. the direction of a rotation, whether it is counterclockwise or clockwise. It is possible to determine the degree, amount, and the revolution's direction.
Transformation based on translational congruence
When an object or shape is transported from one location to another without changing its size, shape, or orientation, the movement is referred to as a translation. During a translation, also known as a slide, every point on an object or shape is moved by the same amount and in the same direction.

For what values of x is the function
positive?
y = |x +4|-1
Answer: x > -3 or x < -5
Step-by-step explanation:
The function is positive when y > 0.
So if we make this function into an inequality, we can solve for the values of x.
0 < |x + 4| -1
1 < | x + 4 |
Absolute values make the answer always positive despite the sign so now we have to solve for x when x + 4 > 1 and when x + 4 > -1.
x = 1 - 4 = -3
x = -1 -4 = -5
So for the function to be positive,
x > -3 or x < -5
