The equation to support the mathematical thinking will be x + 189 = 192 and the numbers needed is 3.
How to calculate the value?It should be noted that the information stated that she needs enough tiles to make three rows with 63 tiles in each row. The number of times needed will be:
= 63 × 3
= 189 tiles
The number of times that Miss Garcia need to make the border tiles cell in boxes of eight tiles in each box will be:
= 192 - 189 = 3
Therefore, 3 tiles are needed. It should be noted that 192 is the multiple of 8 closest to 189.
The equation to support the mathematical thinking will be:
x + 189 = 192
x = 192 - 189

The president of the Huerta Middle School science club suggested a field trip to the local aquarium. Tickets will cost $21.25 for the club adviser and $14.75 for each student who goes. Write an equation showing how the total cost, y, depends on the number of students going, x.
In linear equation , x = 36 is the total cost, y, depends on the number of students going, x.
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.Tickets cost for the club adviser = $21.25
cost for each student who goes = $14.75
Based on the given conditions, formulate x = $21.25 + $14.75
Calculate the sum or difference x = 36

A card is drawn at random from a standard pack of playing cards. then a fair coin is flipped. what is the probability of selecting a 5 and the coin landing on heads?
The probability of selecting a 5 and the coin landing on head is 1/26
In this question, a card is drawn at random from a standard pack of playing cards and fair coin is flipped.
Here, we have two different sample spaces to work with and we want to calculate a compound probability.
Firstly in a deck of cards which contain a total of 52 cards, there are 4 cards labeled 5.
So, the probability of selecting a 5 is:
4/52 = 1/13
Also, in a flip of coin the probability of the coin landing on head is 1/2
Thus the probability of selecting a 5 and the coin landing on head would be,
probability of selecting 5 × probability of the coins landing on head
= 1/13 × 1/2
= 1/26
Therefore, the probability of selecting a 5 and the coin landing on head is 1/26

Josie earns $10 per hour at her job. Her hours vary, but she never works more
than 30 hours in any given week, as she is still in school. We want to write and
graph a function to show her possible earnings for one week.
What is a reasonable domain and range within the context of this situation?
Answer:
Step-by-step explanation:
Work for 30 hours in a week $10 per hour
The domain and the range for the given situation will be:
Domain = [0, 30]
Range = [0, 300]
Given that Josie earns $10 per hour at her job. Her hours vary, but she never works more than 30 hours in any given week,
We need to find the domain and range.
In this situation, the domain refers to the possible values for the input variable, which is the number of hours Josie works in a given week.
The range, on the other hand, refers to the possible values for the output variable, which is her earnings for the week.
For the domain:
Since Josie never works more than 30 hours in any given week, a reasonable domain for this function would be from 0 to 30 hours. We don't consider negative hours (as it doesn't make sense in this context), and the upper limit is set by her maximum weekly working hours.
Domain = [0, 30]
For the range:
The range should be the possible earnings Josie can make in a week based on her hourly rate of $10 per hour.
To find the range, we multiply her hourly rate by the maximum number of hours she can work in a week, which is 30 hours.
Range = [0, 10 x 30] = [0, 300]
So, the function that represents Josie's possible earnings for one week is:
Earnings = f(hours) = 10 x hours
Where "hours" is the number of hours she works in a week, and "Earnings" is the corresponding amount she earns.
The graph of this function will be a straight line passing through the origin (0, 0) and with a slope of 10, representing her earnings increasing linearly with the number of hours worked.
The line will extend up to the point (30, 300) and then flatten out as she cannot earn more than $300 in a week.

If yacht is sailed from A to B on a bearing of 196ºT, the true bearing to sail directly back to point A from point B is 16° T.
To determine the true bearing from point B back to point A, we need to consider the relationship between true bearings and the reciprocal direction.
Given that the yacht is sailed from point A to point B on a bearing of 196° T (True), the reciprocal direction would be the opposite direction, 180° away on the compass.
Thus, to sail directly back to point A from point B, we would need to subtract 180° from the reciprocal direction.
Reciprocal direction - 180°
Therefore, the true bearing from point B back to point A would be:

Find the distance between the pair of points. Round to the nearest tenth, if necessary. (-4,-5) (0,5)
The distance between the two points ( − 4 , - 5 ) and ( 0 , 5 ) is 10 units.
We are given the two points:
( − 4 , - 5 ) and ( 0 , 5 )
We need to find the distance between the two points.
The formula for distance is given as:
Distance = √ (x₂ - x₁)² + (y₂ - y₁)²
Substituting the values, we get that:
Distance = √ ( 0 + 4 )² + ( 5 + 5)²
Distance = √ ( 4 )² + ( 10 )²
Distance = √ 16 + 100

Find the coordinates of the centroid of the triangle with the given vertices. (Lesson 5-2)
R(-6,4), S(-2,-2), T(2,4)
The triangle with vertices located at R(-6 , 4), S(-2 , -2), T(2 , 4) has its centroid located at (-2 , 2).
The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.
To get the centroid of a triangle, use the formula given by:
C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
where C is the centroid of the triangle located at (x , y)
x1, x2, and x3 are the x-coordinate of the vertices of the triangle
y1, y2, and y3 are the y-coordinate of the vertices of the triangle
Let Point 1(x1 , y1) = R(-6 , 4)
Point 2(x2 , y2) = S(-2 , -2)
Point 3(x3 , y3) = T(2 , 4)
Plug in the values in the formula.
C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
C(x ,y) = [(-6 + -2 + 2)/3 , (4 + -2 + 4)/3]

Domain: 1 < x < 5
Range: -10 < y < 2
Step-by-step explanation
First, we need to graph the function. The function is just a linear function, but arranged differently. You can rearrange it to be:
[tex]f(x) = -3x + 5[/tex]
Now graph the function. The slope of it should be -3, and the y-intercept is 5.
To find the domain, just use the relation of the x values given with the function (1 < x < 5).
To find the range, plug the smallest and largest values of the domain into the function given. 1 and 5 should be the numbers you are plugging in. The outputs will be the range. Remember that negative numbers are smaller than positive numbers, so the negative number should be on the left.

In elementary geometry , an angle is that the figure formed by two rays, called the edges of the angle, sharing a standard endpoint, called the vertex of the angle. Angles formed by two rays dwell the plane that contains the rays. Angles also are formed by the intersection of two planes. These are called dihedral angles. Two intersecting curves can also define an angle, which is that the angle of the rays lying tangent to the respective curves at their point of intersection.
Angle is additionally used to designate the measure of an angle or of a rotation. This measure is that the ratio of the length of a circular arc to its radius. within the case of a geometric angle, the arc is centered at the vertex and delimited by the edges . within the case of a rotation, the arc is centered at the middle of the rotation and delimited by any other point and its image by the rotation.
Potentially, an angle denoted as, say, ∠BAC, might ask any of four angles: the clockwise angle from B to C, the anticlockwise angle from B to C, the clockwise angle from C to B, or the anticlockwise angle from C to B, where the direction during which the angle is measured determines its sign (see Positive and negative angles).
