18.75 inches is the length of the rectangle and 18.75 inches is the width of rectangle.

The area of Rectangle is length times of width.

The perimeter of a rectangle is 50 inches.

Perimeter=2(Length+Width)

Length=3W

Perimeter=50 inches

50=2(3W+W)

50=2(4W)

50=8W

Divide both sides by 8

50/8=W

W=6.25

Length=3(6.25)=18.75.

Hence, the length of rectangle is 18.75 inches and width is 6.25 inches.

Jasmine sold the fidget spinner to Bryan for the cost of $5.55.

To find the cost that Jasmine sold the fidget spinner to Bryan for, we need to first find the amount of the markup by multiplying the original price by the markup percentage.

As per the question, the original price of the fidget spinner is $3, and the markup percentage is 850%, so the markup amount is :

$3 × 850% = $2.55.

Next, we need to add the markup amount to the original price to find the selling price. So, the selling price is :

$3 + $2.55 = $5.55.

Therefore, Bryan paid $5.55 for the fidget spinner that Jasmine had just sold him.

Answer:

All sum of Traingle Angle is 180°

180= 87+31+ Angle C

Angle C = 180 - (31+87)

Angle C = 62

Answer:

A. One Solution

Step-by-step explanation:

To determine if a system of equations has no solutions, infinitely many solutions, or exactly one solution, we can solve the system by any method, such as elimination or substitution.

In this case, we can solve the system by elimination. Multiplying the first equation by -2 and adding it to the second equation, we get:

0x + 4y = -3

This equation tells us that y must be equal to -3/4, but we still need to check if this value of y satisfies the original equations. Substituting -3/4 for y in the first equation, we get:

2x + (-3/4) = 7

Solving this equation for x, we get x = 5/4. Substituting this value of x and -3/4 for y in the second equation, we get:

-2(5/4) + 2(-3/4) = -5

which simplifies to:

-5/2 + (-3/2) = -5

This equation is true, so the solution of the system is x = 5/4 and y = -3/4. Since the system has a unique solution, the answer is (A) One Solution.

Twice a number is equal to negative four :

                       2n = -4

Equation:

An equation is a formula that expresses equality by connecting two expressions with an equal sign '='. Equations and their cousins ​​in other languages ​​may have subtly different meanings. For example, in French an equation is defined as containing one or more variables, but in English any formula in its proper form consisting of two equations joined by an equal sign is an equation.

The equation resembles a weighted scale. When two bowls have the same weight (such as grain), the two weights balance the scale and are said to be equal. If you remove a certain amount of grain from one pan of the scale, you must remove the same amount of grain from the other pan to keep the scale balanced. More generally, the equation remains in equilibrium if the same operation is performed on both sides.

According to the question:

If you wanted to solve your equation:

   2x = -4

[tex]\text{as x} \to \infty, \ \text{y} \to -\infty\\\\\text{as x} \to -\infty, \ \text{y} \to \infty[/tex]

Rises to the left; falls to the right

============================================================

Explanation:

The leading term is what determines the end behavior of any polynomial function.

The leading term has the largest exponent. The other terms will have no effect on the end behavior.

As x gets really large in the positive direction, so does x^3. But the -2 out front will flip to have y go to negative infinity.

Therefore:  [tex]\text{as x} \to \infty, \ \text{y} \to -\infty[/tex]

We can informally think of this as "falls to the right".

---------------------------

As x heads to the left, x^3 becomes further negative. But -2 out front makes -2x^3 to be positive.

So [tex]\text{as x} \to -\infty, \ \text{y} \to \infty[/tex] aka "rises to the left".

Whatever x does, y does the opposite. If x goes positive, then y goes negative and vice versa.

-------------------------

The end behavior is therefore

[tex]\text{as x} \to \infty, \ \text{y} \to -\infty\\\\\text{as x} \to -\infty, \ \text{y} \to \infty[/tex]

x and y are opposite.

We can summarize that notation as saying "rises to the left, falls to the right".

Answer:

his gives us that Chris is walking 69 feet per minute faster than Heidi.

Step-by-step explanation:

1 mile is equal to 5,280 feet, we can multiply 3 by 5,280 to find that Heidi is walking 15,840 feet per hour.

Next, we need to convert both speeds to feet per minute. Since there are 60 minutes in an hour, we can divide both speeds by 60 to convert them to feet per minute. This gives us that Heidi is walking 264 feet per minute and Chris is walking 333 feet per minute.

Finally, to find out how much faster Chris is walking than Heidi, we can subtract Heidi's speed in feet per minute from Chris's speed in feet per minute.

The amount of money the carnival committee should expect to pay for prizes for the booth is 218.7 dollars.

Therefore, the answer is option C.

At a booth at the school carnival in past years, they've found that 22% of students win a stuffed toy ($3.60), 16% of students win a jump rope ($1.20), and 6% of students win a t-shirt ($7.90). The remaining students do not win a prize.

If 150 students play the game at the booth, the amount of money the carnival committee expect to pay for the prizes of the booth is as follows:

total student that partake = 150

number that win stuffed toy  = 22% of 150

number that win stuffed toy = 33

number that win  jump rope = 16% of 150

number that win  jump rope = 24

number that win  t-shirt = 6% of 150

number that win  t-shirt = 9

Therefore,

prizes for those that win stuffed toy = 33 × 3.60 = 118.8 dollars

prizes for those that win jump rope = 24 × 1.20 = 28.8 dollars

prizes for those that win t-shirt = 9 × 7.90 = 71.1 dollars

Hence,

total amount the committee is expected to pay for prizes = 118.8 + 28.8 + 71.1 = 218.7 dollars

The other two roots of the polynomial are x = (7 + √33)/4 and x = (7 - √33)/4.

A polynomial is an expression of one or more algebraic terms, each of which is composed of constants and/or variables raised to non-negative integer powers. A polynomial can be written in the form of an equation, where the coefficients of the terms form a sequence of numbers. Polynomials can also be expressed using a factored form, in which each of the terms is the product of a coefficient and a single variable or factor. Polynomials are commonly used to model real-world phenomena, such as the behavior of a system or process. The degree of a polynomial, which is the highest degree of the terms, determines the number of solutions it has. For example, a polynomial of degree two has two solutions while a polynomial of degree three has three solutions. The solutions of a polynomial are determined by solving the equation formed by the polynomial's terms.

Let us first rewrite the polynomial in a standard form:

2x^3 + 7x^2 + ax + 2 = 0
We can factor this polynomial using the Factor Theorem. The Factor Theorem states that if a is a root of a polynomial, then x-a is a factor of the polynomial.
Since x=-2 is a root of the polynomial, the factor (x+2) must be a factor of the polynomial.
Therefore, we can rewrite the polynomial as:
2x^3 + 7x^2 + ax + 2 = 2(x+2)(x^2 + bx + c)
Now, we can use the coefficients of the polynomial to solve for a, b and c.
Comparing the coefficients of the polynomial on both sides:
2 = 2c
7 = b
a = -2b-4c
Substituting the values of c and b in the equation for a, we get:
a = -2(b) - 4(2)
 = -2(7) - 8
 = -16
Therefore, the value of a is -16.
To find the other roots of the polynomial, we just need to solve the remaining factor (x^2 + bx + c) = 0.
Substituting the values of b and c, we get:
x^2 + 7x + 2 = 0
We can solve this equation using the Quadratic Formula:
x = [-b ± √(b^2 - 4ac)]/2a

Substituting the values of a, b and c, we get:
x = [-7 ± √(7^2 - 4(2)(2))]/2(-2)
 = [-7 ± √(49 - 16)]/-4
 = [-7 ± √33]/-4
Therefore, the other two roots of the polynomial are x = (7 + √33)/4 and x = (7 - √33)/4.

The degree of this polynomial is 3 and the leading coefficient is 1. Three zeros are 3, 4+i, 4-i bc, and a-bi if a+bi is zero, also known as the conjugate postulate. With this information, we can say that the factors are (x-3)(x-(4+i) )(x-(4-i)).
