Step-by-step explanation:
1.806 (to the nearest thousandth)
The number 1.80642 would round down to 1.806
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
We need to round 1.80642 to the nearest hundredth,
We can see that the 1.80642 is below 2 so it goes down, and it rounds down to 1.80642 instead of, 14.62 then that would round up to the decimal is higher than 1.
1.80642 rounded to the nearest thousandth is 1.806.

Betina is going to put floor tiles down in the bathroom. Each tile is a square and measures 75mm down one side. What is the area of one tile? mm²
Answer:
5625mm²
Step-by-step explanation:
The area of a square is found by multiplying the length of one side by itself. So if each tile is a square and measures 75mm on one side, then the area of one tile is:
75mm x 75mm = 5625mm²

The production of congruent figures involves stiff rigid transformation Even if you could imagine them as forms that "appear exactly the same," congruent figures.
Rigid transformation: what is it?During accurate modification of a geometric object, distance between each point pair is maintained. In other words, precise transformations maintain an object's size and shape. For instance, the angles and lengths of a triangle are preserved throughout a rigid transformation. Imagine a stiff shape, such as one made of cardboard, distorting. Even when the shape is rotated, mirrored, and moved left and right, nothing changes.
Here,
When I used putty to create a mold, it was the opposite. After that, users can stretch and twist the objects.
These ratios are not exact though. The distance between every pair of points is altered when the shape is stretched.
Applying rotations, reflection, and translations—three different forms of transformations—can result in congruent shapes.
In reality, by mixing any or all of these three transformations, any congruent shape pairs can be matched to one another.

Let L1 be a line that passes through the points (–2, 9) and (1, 3), and let L2 be the line that passes through the points (–4, 10) and (3, –4). Determine whether L1 and L2 are parallel
The two lines L1 and L2 are parallel
How to identify if the lines are parallelFor two lines to be parallel the slope must be equal, hence we calculate the slope of the two lines
The slope, m of the linear function L1 is calculated using the points (–2, 9) and (1, 3)
m = (y₀ - y₁) / (x₀ - x₁)
m = (9 - 3) / (-2 - 1)
m = (6) / (-3)
m = -2
The slope, m of the linear function L2 is calculated using the points (–4, 10) and (3, –4)
m = (y₀ - y₁) / (x₀ - x₁)
m = (10 + 4) / (-4 - 3)
m = (14) / (-7)
m = -2

Three numbers sum to 117. The second number is 10 less than the first. The third number is 2 more than half the first. What are the three numbers?
Answer:
Step-by-step explanation:
The three numbers are 50, 40, and 27.
We can solve this equation by setting up a system of equations.
Let x be the first number, y be the second number, and z be the third number.
x + y + z = 117
y = x - 10
z = (1/2)x + 2
Substituting the equation for y into the first equation, we get:
x + (x - 10) + (1/2)x + 2 = 117
2x - 8 = 117
2x = 125
x = 62.5
Substituting this value of x into the other equations, we get:
y = x - 10 = 62.5 - 10 = 52
z = (1/2)x + 2 = (1/2)62.5 + 2 = 32.5 + 2 = 34.5
Rounding these values, the three numbers are 50, 40, and 27.

The compound inequality for the graph given is -2 < x < 5.
How to find the compound inequality ?When a compound inequality is graphed such that there is an open circle instead of a filled - in circle over a number, then it means that x is either greater than this value, or less than this value. In other words, x is not equal to this value.
The circles over - 2 and 5 are not filled in which means that x is greater or less than - 2 and 5.
x is less than 5 because the arrow goes from 5 to infinity and x is greater than - 2 for the same reason.
The compound inequality is therefore:

Answer:
(0, -3)
Step-by-step explanation:
You want a point on the graph of 4x -y = 3.
PointIt is often convenient to choose an intercept when looking for a point that will satisfy the equation. Here, it is convenient to set x=0 to obtain y=-3.
A solution ordered pair is (0, -3).

Additional comment
Here, it will be more convenient to choose a value for x. Choosing a value for y can result in fractions becoming involved for the values of x. We prefer to avoid that.
y = 4x -3 . . . . . . y=-3 when x=0; y=1 when x=1, so (1, 1) is another solution

Underline the hypothesis and circle the conclusion in the following conditional statement. Then write the converse, inverse, and contrapositive. Determine whether each statement is true or false.
Conditional: If the stars are visible, then it is night.
Converse:
Inverse:
Contrapositive:
The hypothesis is "the stars are visible".
The conclusion is "it is night".
This is because a conditional follows the format of "if hypothesis, then conclusion". It shortens to "If P, then Q".
It's fairly clear that the original conditional is true. There are some extremely rare exceptions, but mostly stars are only visible at night.
--------------------------
The converse is "If it is night, then the stars are visible".
Reason: The original "If P, then Q" format flips to "If Q, then P" when forming the converse.
The converse is false. The fact that it is night does not automatically lead to the stars being visible. For example, storm clouds at night can obscure the stars.
--------------------------
The inverse is "If the stars aren't visible, then it is not night".
We negate both the hypothesis and conclusion. The format of the inverse is "If not P, then not Q".
Like the previous statement, the inverse is false. Why? Because the stars not being visible doesn't automatically mean it's not night. We could have storm clouds covering up the stars. Or perhaps the city has a lot of light pollution to drown out the stars.
The converse and inverse have the same truth value, as they are equivalent statements (just phrased slightly different ways).
--------------------------
The contrapositive is "If it's not night, then the stars aren't visible".
The original conditional "If P, then Q" leads to the contrapositive "If not Q, then not P". We swap the positions of P and Q. Also, we negate each piece. In a sense, we combine both the inverse and converse operations to get a contrapositive.
The contrapositive is true because "not night" of course means "day", in which the stars aren't present in the sky. The contrapositive and original conditional have the same truth value. The contrapositive is a way to rephrase the original conditional.
Answer:
Hypothesis: "the stars are visible"
Conclusion: "it is night"
Converse: "If it is night, then the stars are visible" - false.
Inverse: "If the stars are not visible, then it is not night." - false.
Contrapositive: "If it is not night, then the stars are not visible" - true.
Step-by-step explanation:
Conditional statement
"If this happens, then that will happen."
Hypothesis: The part after the "if".Conclusion: The part after the "then".Given conditional statement:
"If the stars are visible, then it is night."Therefore:
Hypothesis: "the stars are visible"Conclusion: "it is night"Converse statement
The converse of a conditional statement is formed by switching the hypothesis and the conclusion.
Therefore, the converse of the given conditional statement is:
"If it is night, then the stars are visible"This is a false statement as the stars will not be visible if there is cloud cover at night.
Inverse statement
The inverse of a conditional statement is formed by negating the hypothesis and the conclusion.
Therefore, the inverse of the given conditional statement is:
"If the stars are not visible, then it is not night."This is a false statement as the stars will not be visible if there is cloud cover at night.
Contrapositive statement
The contrapositive of a conditional statement is when both the hypothesis and conclusion are negated and then switched.
Therefore, the contrapositive of the given conditional statement is:
"If it is not night, then the stars are not visible"It is difficult to say if this is a true or false statement without more information, as it is possible to see bright stars during the daytime through a telescope or a really powerful pair of binoculars.
If we are to assume that "visible" means "visible to the eye" without any magnification assistance, then the statement is true (if we exclude the sun, which is a star).
