Answer:

the answer is C

Step-by-step explanation:

The angle measures of each vertex of the garden are 53.13 degrees.

In Parallelogram ABCD, diagonals AC and BD intersect at point A = √7.

Angle is a geometric figure that can be described as the amount of rotation between two straight line or planes and angle is measured in degree with a full circle being 360°.

1. To determine the angle measures of each vertex of the garden, we must first calculate the angles formed by each side. For example, the angle formed by sides AB and BC can be found by using the inverse tangent function. The equation would be

arctan(BC/AB) = arctan (4/3) = 53.13 degrees.

The angles for the other sides can be calculated in the same way. We can then use the sum of angles theorem to calculate the angles at each vertex. Since the garden is an irregular shape, the angles at each vertex will be different.

2. In Parallelogram ABCD, diagonals AC and BD intersect at point A. To calculate , we can use the distance formula.

The equation would be = √((x2 – x1)2 + (y2 – y1)2).

For the coordinates given, we would have

= √((2 – 5)2 + (5 – 1)2)

= √(-9 + 16)

= √7.

Answer:b

Step-by-step explanation:

Based on Mickey's work, QUAD is a rectangle because the opposites sides are parallel and the angles formed are right angles (perpendicular).

In Mathematics and Geometry, a rectangle can be defined as a type of quadrilateral in which its opposite sides are equal and all the angles that are formed are right angles.

In any rectangle, each of the two (2) opposite sides are equal and parallel and the two (2) diagonals are equal.

Based on the information provided about Mickey's work, we have the following:

Diagonal AD = Diagonal QU = √20 units.

Diagonal DQ = Diagonal UA = √5 units.

Slope of QU × Slope of UA = 2 × (-1/2) = -1.

Slope of AD × Slope of DQ = 2 × (-1/2) = -1.

In conclusion, we can logically deduce that sides QU and AD is perpendicular to sides UA and DQ respectively.

Wayne's Actual ACT score is 19.2 where mean is 21, standard deviation is 5 and the Z - score is -0.6.

Standard Deviation:

Standard deviation is  a measure of the dispersion of a set of numerical values from their mean.

The general form of the standard deviation is,

\(SD=\sqrt{\frac{\sum (x_i-\bar{x})}{n} }\)

where

xi is each value in the data set,

x-bar is the mean, and

n is the number of values in the data set.

Given,

Mean = 21.

Standard deviation = 5

Wayne's standardized score on the act = −0.6 .

Here we need to find the Wayne's Actual ACT score.

Let x be the Wayne's Actual ACT score.

So,
=> z-score = (x - mean)/SD

Apply the values on it,

=> -0.6 = (x - 21) / 3

=> -1.8 = x - 21

=> x = 21 - 1.8

=> x = 19.2

Therefore, Wayne's Actual ACT score is 19.2

Answer: <less than >greater than ≥ greater than or equal to ≤ less than or equal to

Step-by-step explanation:

Answer: To determine the break-even quantity, we need to find the point where the revenue equals the cost. In other words, we need to solve the equation R(x) = C(x).

Given:

Setting R(x) = C(x), we have:

Subtracting 135x from both sides of the equation:

Simplifying the left side:

Dividing both sides by 45:

The break-even quantity is 1,236 units.

Since the break-even quantity (1,236 units) is less than the maximum number of units that can be sold (2,097 units), the firm can produce the product because it would make money.

To determine the break-even quantity and decide whether to proceed with the production of the new product, we need to analyze the cost and revenue data provided.

The cost function is given as C(x) = 135x + 55,620, where x represents the quantity of units produced. The revenue function is given as R(x) = 180x. To break even, the total cost and total revenue should be equal. We can set up an equation based on this condition: C(x) = R(x). Substituting the given cost and revenue functions: 135x + 55,620 = 180x

To solve for x, we can subtract 135x from both sides: 55,620 = 45x. Now, divide both sides by 45: x = 1,236. The break-even quantity is 1,236 units.

Since the number of units that can be sold is no more than 2,097 units, which is greater than the break-even quantity of 1,236 units, the firm can produce the product. The break-even point indicates the minimum number of units that need to be sold to cover the costs, and since the firm can sell more than the break-even quantity, it has the potential to make a profit. However, further analysis of other factors such as market demand, competition, and potential profitability should also be considered before making a final decision.

Answer:

7x - 1

Step-by-step explanation:

Whole rectangle:

Length = x + 5

Width = x - 1

Area of the whole triangle = length × width

= (x + 5) (x - 1)

= x² - x + 5x - 5

= x² + 4x - 5

Unshaded rectangle:

Length = x + 1

Width = x - 4

Area of the unshaded rectangle = length × width

= (x + 1) (x - 4)

= x² - 4x + x - 4

= x² - 3x - 4

Area of the shaded region = Area of the whole rectangle - Area of the unshaded rectangle

= (x² + 4x - 5) - (x² - 3x - 4)

= x² + 4x - 5 - x² + 3x + 4

= 7x - 1

Area of the shaded region = 7x - 1

Answer:

El costo de alquiler de cada película es $26 y el costo de alquiler de cada juego de video es $59.50.

Step-by-step explanation:

A partir de la información proporcionada, puedes escribir las siguientes ecuaciones:

4x+8y=580 (1)

2x+3y=230.50 (2), donde:

"x" es el costo de alquiler de cada película y "y" es el costo de alquiler de cada juego de video.

Primero, puedes despejar x en (1):

4x=580-8y

x=145-2y (3)

Segundo, debes reemplazar (3) en (2):

2(145-2y)+3y=230.50

290-4y+3y=230.50

290-230.50=4y-3y

y=59.50

Tercero, debes reemplazar el valor de y en (3) para encontrar el valor de x:

x=145-2(59.50)

x145-119

x=26

De acuerdo a esto, la respuesta es que el costo de alquiler de cada película es $26 y el costo de alquiler de cada juego de video es $59.50.

The total worth of Sipho's investment after 7 years is R18,131.25.

The accrued amount for a simple interest is expressed as;

A = P( 1 + rt )

Where A is accrued amunt, P is principal, r is interest rate and t is time.

Given the data in the question;

First, we convert R percent to r a decimal

r = R/100

r = 20.25%

r = 20.25/100

r = 0.2025 per year

Plug the given values into the above formula and solve for accrued amount A.

A = P( 1 + rt )

A = R7,500( 1 + ( 0.2025 × 7 ) )

A = R7,500( 1 + 1.4175 )

A = R7,500( 2.4175 )
