The playground's length and breadth are 12 yards and 17 yards, respectively.

The playground's area is 204 square yards, according to the statistics provided in the inquiry.

204 square yards is the area.

The playground's breadth is 5 yards more than its length.

Let the playground be 'l' yards long.

The playground's width will then be (l + 5) yards.

The formula for the playground area is Length × Width.

A =  Length x width

204 = l (l + 5)

204 = + 5l

+ 5l - 204 = 0

+ 17l - 12l - 204 = 0

l (l + 17) -12 (l + 17) = 0

(l + 17) (l - 12) = 0

(l + 17) = 0 or (l - 12) = 0

l = -17 or l = 12

The length value cannot be negative.

As a result, the length is 12 yards.

The breadth is thus equal to l + 5.

Width = 12 + 5

17 yards wide

As a result, the length is 12 yards and the breadth is 17 yards.

Option (b) is the right answer.

Alex will not be able to complete his job. According to the measurement given for the coil, the electrician will not be able to complete the job.

The circumference of the coil of wiring can be calculated with

C= 2πr

where r is the radius and π= 3.14

The radius can be calculated by dividing the diameter by 2. Then:

r= 18 inches ÷ 2

r= 9 inches

Convert 9 inches to yards (1 yard= 36 inches)

(9 inches)(1 yard ÷ 36 inches) = 0.25 yard

Substitute this radius into the formula:

C= 2(3.14)(0.25 Yard)

C= 1.57 Yard

Since there are 21 circles of wire, we need to multiply C= 1.57 yards by 21

C = (1.57 Yard)(21) = 32.97 Yard

The coil has 32.97 yards of wire and Alex needs 34 yards, therefore, this coil will not be enough to complete the job.

Answer: No Solution

Step-by-step explanation: When you use the elimination method on second equation by multiplying it by 2 you get two equations that add up to a different solution. Since the variable coefficients are the same on both, there will be no solution.

Common theorems, properties, or strategies to the proof of the Triangle Proportionality Theorem and its converse include using similarity and congruence, angle-angle criterion, and transitive property of equality.

The Triangle Proportionality Theorem states that if a line is drawn parallel to one side of a triangle to intersect the other two sides, then the ratio of the lengths of the intersecting lines is equal to the ratio of the lengths of the corresponding sides of the triangle.

The converse of the Triangle Proportionality Theorem states that if two pairs of corresponding sides in two triangles are proportional, then the two triangles are similar.

Overall, these theorems, properties, and strategies form the basis for proving both the Triangle Proportionality Theorem and its converse, and they are used to establish the relationships between the lengths of sides and angles in triangles.

Answer:

  (x, y) = (-3, -5)

Step-by-step explanation:

You want to solve the given system of equations by elimination.

To eliminate a variable from the equations, we need to add them in such a way that the coefficients for one of the variables have a total of zero.

Here, we observe that the y-coefficients are the same, so subtracting one equation from the other will cancel the y-terms. We want the result of that subtraction to give an equation with x having a positive coefficient, so we elect to subtract the second equation from the first:

  (2x -3y) -(-5x -3y) = (9) -(30)

  7x = -21 . . . . . simplify (y-terms are gone, x-term has positive coefficient)

  x = -3 . . . . . . . divide by 7

The value of y can be found from either equation. We choose to use the first one:

  2x -3y = 9

  2(-3) -3y = 9 . . . . . . substitute -3 for x in the first equation

  -15 = 3y . . . . . . add 3y-9

  -5 = y . . . . . . . divide by 3

The solution is (x, y) = (-3, -5).

The quantity of lunch specials conceivable is 2 sandwiches * 2 beverages * 3 treats = 12.

The lunch exceptional at Teresa's Café incorporates a sandwich, a beverage, and a sweet. There are 2 choices for sandwiches, 2 choices for beverages, and 3 choices for treats. To decide the quantity of conceivable lunch specials, we want to track down the quantity of blends of these things. The recipe for mixes is n! /(r! * (n - r)!). Nonetheless, since every thing is chosen just a single time, we can basically duplicate the quantity of choices for every thing. For this situation, there are 2 choices for sandwiches, 2 choices for beverages, and 3 choices for pastries, so 2 * 2 * 3 = 12 potential lunch specials.

The correct answer for the measures of the sides of the triangle is (D) 8 cm, 10 cm, and 4√41 cm.

The sine of an angle is a mathematical function that describes the relationship between the lengths of the sides of a right triangle and the angles within that triangle. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse.

Let's call the side opposite the angle with sine 4.5 "a", and the side adjacent to that angle "b". Using the definition of sine, we can write the following equation:

sin(θ) = a/c

where c is the length of the hypotenuse. We can substitute 4.5 for the sine:

4.5 = a/c

Cross multiplying, we get:

4.5c = a

So, given the length of c, we can find a.

The only option that gives a positive value for c is (D), with c = √41 cm. In this case, a = 4.5 * √41 = 4√41 cm, which matches the value in the answer choices.

Answer:

3x+5y = -13

Step-by-step explanation:

Since there are two variables, you must solve for one of them first. One way we can do that is through elimination.

X seems the easiest to eliminate.

We can subtract the two equations.

 x - 4y = -10
- 2x+9y = -3

If we subtract it like this, it wouldn't eliminate any variables. So, let's multiply the first equation by 2 so both equations have 2x.

 2x - 8y = -20
- 2x+9y = -3
Now, subtract the equations.

-17y = -17

We can solve for y now.

y = 1

Since we have y's value, we can solve for x. Plug y back into one of the equations.

x - 4(1) = -10

x - 4 = -10

x = -6

Now that we have both the x and y values, simply plug it into 3x+5y.

3(-6) + 5(1)

-18 + 5
-13

So the answer is -13

The correct option regarding the number of solutions of the sustem of equations is given as follows:

The range of this function is all real numbers as the long function will never return a negative value. The value of b determines the exact range of the function, as it shifts the graph up or down.

The formula is: f(x) = - log(5 - x) + b.

Limitation for the f domain:

5 – x > 0

x < 5

Hence, f's domain is

Dom(f) = {x ∈ R:  x < 5}

Alternatively by notating intervals,

Dom(f) = [– ∞, 5].

Secondly, we wish to demonstrate that there is always an x Dom(f) for any given y R.

y = f(x) (x)

Once we've demonstrated that, we can say that f's operating range is R. (all real numbers).

How to find x in an equation:

[tex]y = f(x)\\y = - log(5 - x) + b\\y - b = - log(5 - x) (5 - x)\\-(y - b) = log(5 - x) (5 - x)\\b - y = log(5 - x) (5 - x)\\5 - x = 10^{(b - y) (b - y)}\\x = 5 - 10^{(b - y) (b - y)}\\[/tex]

No, the number of students at the school is not proportional to the number of teachers. In a proportional relationship, two quantities have a constant ratio. However, in this case, the number of teachers is not directly proportional to the number of students because there is a fixed number of teachers regardless of the number of students. Even if the number of students changes, the number of teachers remains the same.

A more appropriate way to describe the relationship between the number of teachers and students at the school is to say that there are 2 teachers for every 48 students, or that the ratio of teachers to students is 2:48, which simplifies to 1:24.

The ratio of the number of astronauts on Earth to the total number of astronauts is 7 : 30.

A ratio is a mathematical expression that compares two or more values by dividing the size of one value by the size of another.

Ratios can be expressed in several different forms, including fractions, decimals, or percentages, and can be used to compare quantities, measurements, or other values in a meaningful way.

Ratios provide a way to express the relationship between two or more values in a compact and concise format, and can be used in a variety of fields, including mathematics, science, finance, and engineering.

If the space program has 23 astronauts in outer space and 7 astronauts on Earth, then the ratio of the number of astronauts on Earth to the total number of astronauts is:
