The perimeter of scale drawing of rectangular classroom floor is 42 inches.

Based on the mentioned information, let us first calculate the width of floor of classroom according to the scale drawing.

Length/width of original classroom floor = length/width of scale drawing

30/33 = 10/width

As we know, 1 foot = 12 inches

So, length = 360 inches and width = 396 inches

Width = (396 × 10)/360

Cancelling zero as it is common in both numerator and denominator

Width = 396/36

Performing division on Right Hand Side of the equation

Width = 11 inches

Perimeter of scale drawing = 2 (length + width)

Perimeter = 2( 10 + 11)

Performing addition

Perimeter = 2 × 21

Performing multiplication

Perimeter = 42 inches

Thus, perimeter of the rectangle is 42 inches.

For the triangle ABC the interior angles measures ∠A = 48°, ∠B = 82°, and ∠C = 50°.

What are triangles?

Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.

According to the angles of a triangle theorem, the sum of angles of a triangle is 180°.

The measure of ∠A = 4x.

The measure of ∠B = 7x - 2.

The measure of ∠C = 5x - 10.

The equation is -

∠A + ∠B + ∠C = 180°

Substitute the values into the equation -

4x + 7x - 2 + 5x - 10 = 180

Collect the like terms -

4x + 7x + 5x = 180 + 2 + 10

16x = 192

x = 192/16

x = 12°

So, the measure of ∠A = 4(12) = 48°.

The measure of ∠B = 7(12) - 2 = 82°

The measure of ∠B = 5(12) - 10 = 50°

The interior angles of the triangle are 48°, 82° and 50°.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Given

Number of times Lucia ran the race=n=3

Slowest time= x_1=56.3 sec

Fastest Time= x_2=52.2 sec

Average time=54.0 sec

Since, we know the average time and two of the three race times, we can use the average formula to calculate the third race’s time.

Let  

x_3=the third race^' s time

So,

Average=(Sum of values)/(Number of values)

Average =  (x_1+ x_2+ x_3)/n

Putting the values

54.0=  (56.3+ 52.2+ x_3)/3

Multiplying 3 with 54.0 and adding 56.3 and 52.2

162= 56.3+52.2+ x_3

162= 108.5+ x_3

x_(3 )=162-108.5

If the distances between a point and each object in the set are equal, the point is said to be equidistant from the set.

When a point is equidistant from two other points, it is at the same distance from both of them. The distance between two points may be computed using the distance formula and the coordinates of the two points.

In geometry, a locus is a set of points that satisfy a specific condition or circumstance for a form or figure. The locus is pluralized as loci. The region is the location of the locus. The term locus comes from the word location.

Domain[tex]{}[/tex]                    (-∞, ∞)                         Range            (-∞, 4]

The graph of a parabola is a u (or n) shaped curve obtained by the intersection of a cone and a plane which is parallel to the slant of the cone.

The x-intercepts are the point the graph intersects the x-axis, where the y-value is zero, y = 0. From the graph, the x-intercepts are;(-1, 0), and (3, 0)

The y-intercept is the point at which the graph intersects the y-axis, which is the point the x-value is 0, (x = 0). The graph indicates that the y-intercept is (0, 3)

The vertex of the parabolic graph is the highest (or lowest) point on the graph, therefore, from the graph in the question, the vertex point is; (1, 4)

The axis of symmetry is the line that divides the graph into two mirror halves, which is the line passing through the vertex and parallel to the y-axis. The axis of symmetry is therefore the line; x = 1

The domain is the set of the possible input values of the graph of the function, which is the set of the possinble x-values.

The graph indicates that the x-values can decrease and increase to -∞ and ∞. The domain is therefore; (-∞, ∞).

The region where the graph is increasing is fro x = -∞ to just before x = 1. The interval where the graph is increasing is therefore; (-∞, 1)

Similarly, the interval the graph is decreasing is; (4, ∞)

The graph is positive in the region above the x-axis. The interval over which the graph is positive is therefore between the x-intercepts, which is; (-1, 3)

The graph is negative in the region below the x-axis. The interval in which the graph is negative are; (-∞, 1), and (3, ∞)

The range is the set of possible output of the graph, therefore, the range is the set of the possible y-values, which is; (-∞, 4]

Answer:

Step-by-step explanation:

1)   The domain can be ANY value of 'x' except 'x' that cause the denominator to = 0    and it cannot be 'x' values that cause the denominator to be negative    as this is not allowed

so   x cannot be 5 or greater

       (-∞ , 5)   is the domain in interval notation

    or you could just write   x < 5      

2) you cannot have a negative square root so the domain would be all 'a'

       that the numerator would be 0 or greater (you CAN have a square root of '0' in the numerator)

             7-5a ≥ 0

               7 ≥ 5a

               7/5 ≥ a     or flipping it around    a ≤ 7/5

The solution to the system of linear equations using the Equal Value Method is Y = -(8y / 6) - 21.

The Equal Value Method is a technique used to solve a system of linear equations. To solve a system of linear equations using the Equal Value Method, we first write out the two equations. In this case, we have the two equations:

Y = -8x - 21

y = 6x + 7

Next, we need to solve one of the equations for one of the variables. We can solve for x in the first equation, giving us x = (-21 - Y) / -8. We can then substitute this into the second equation, giving us y = (6(-21 - Y) / -8) + 7. We can then expand and simplify this equation, giving us y = (126 + 6Y) / -8.

Finally, we can set the two equations equal to each other and solve for Y. This will give us 126 + 6Y = -8y, which simplifies to 6Y = -8y - 126. We can then divide both sides by 6 to get Y = -(8y / 6) - 21.

Therefore, the solution to the system of linear equations using the Equal Value Method is Y = -(8y / 6) - 21.

Answer:I hope this helps

Step-by-step explanation:

The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).

End behavior refers to the appearance of a graph as it is followed indefinitely in either horizontal direction. Leading coefficient POSITIVE: both "ends" are UP. Leading coefficient NEGATIVE: both "ends" are DOWN. Leading coefficient POSITIVE: left end is DOWN and right end is UP.

If the degree is odd and the lead coefficient is positive, then the right end of the graph will point up and the left end will point down. If the degree is odd and the lead coefficient is negative, then the right end of the graph will point down and the left end will point up
