Case T: A = 88 cm²

Case M: A = 72 cm² + 6 · x cm², where x is a non-negative real number.

Case 1: A = 132 cm² (Correct choice: B)

Case 2: A = 250 m² (Correct choice: C)

Case 3: A = 36 m² (Correct choice: A)

In this problem we need to determine the area of rectangles and combinations of rectangles, whose formula is shown below:

A = ∑ (b · h)

Where:

Now we proceed on each case:

Case T

A = (4 cm)² + (12 cm) · (6 cm)

A = 16 cm² + 72 cm²

A = 88 cm²

Case M

A = (18 cm) · (4 cm) + (6 cm) · (x cm)

A = 72 cm² + 6 · x cm²

Case 1

A = (6 cm)² + (12 cm) · (8 cm)

A = 36 cm² + 96 cm²

A = 132 cm² (Correct choice: B)

Case 2

A = (15 m)² + (5 m)²

A = 250 m² (Correct choice: C)

Case 3

A = (3 m) · (12 m)

Answer:

Step-by-step explanation:

“The area of a rectangular garden is 120 square meters.”

LW = 120

“The width is 4 meters longer than one-half of the length.”

W = 0.5L + 4

L = 2W-8

Substitution

(2W-8)W = 120

2W^2-8W-120 = 0

W^2 -4W-60 = 0

W = 10, -6

-6 is an extraneous solution.

W = 10 meters

L = 2W-8 = 12 meters

To sketch the graph of a quadratic equation, you can use a graphing calculator, which is a handy tool that can produce a visual representation of the equation. For instance, let's take the quadratic equation y = -0.5x² + 0.7x - 5.1 and sketch its graph using a graphing calculator.

When we enter this equation into the graphing calculator, we can see a U-shaped curve that is symmetric about the vertical line passing through the vertex. The vertex is the point where the parabola changes direction and is given by the formula x = -b/2a, y = f(x), where f(x) is the value of y at the vertex.

Now let's examine the given options and determine their domain and range based on the graph of the quadratic equation.

all real numbers, R: (y ≤ -4.855)

For this option, we can observe that the parabola opens upward, and the vertex is at (0.7, -5.35).

Step-by-step explanation:

Based on the information given, we have a diagram with two sides labeled as 13.3 mm and 5.5 mm, and another side labeled as X mm.

To find the length of X, we can use the fact that the sum of the lengths of the sides of a triangle is equal to the perimeter.

Perimeter = 13.3 mm + 5.5 mm + X mm

The perimeter is the total distance around the triangle. Since we have three sides, the perimeter is the sum of the lengths of those sides.

To find X, we can subtract the sum of the known sides from the perimeter:

X mm = Perimeter - (13.3 mm + 5.5 mm)

Since the value of X is not given, we cannot calculate it without the perimeter value. If you provide the perimeter value, I can help you find the length of X.

A triangle is a three-sided polygon that consists of three edges and three vertices.

The two triangles PQR and P'Q'R' are similar triangles

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Firstly let us find the P'Q' by using pythagoras theorem

R'Q'²=PR'²+P'Q'²

12²=10²+P'Q'²

144-100=P'Q'²

44=P'Q'²

P'Q'=6.6

The value of PR is x

The value of x is 7. as R it is a midpoint of P'Q'R'

Hence the value of x is 7

Answer:

770cents

Step-by-step explanation:

If a report is 81 pages long, 12 copies will be (81 * 12)pages long

12copies = 972 pages long

If 500 pages costs $3.96 each

972 pages will cost $x

Cross multiply

500x = 972 * 3.96

500x = 3,849.12

x = 3,849.12/500

x = 7.69824

Hence the cost of the reports is $7.69824

Convert to cents;

$1 = 100cents

$7.69824 = y

y = 7.69824 * 100

y = 769.824 cents

y ≈ 770 cents (to the nearest cent.)

Hence the paper is going to cost 770cents (to the nearest cent)

The numbers are 1 and 8.

We have,

Let's assume the lesser number as "x" and the greater number as "8x".

According to the given information, when the lesser number is subtracted from the greater, the result is 2 more than 5 times the lesser number:

8x - x = 5x + 2

Simplifying the expression:

7x = 5x + 2

Subtracting 5x from both sides:

2x = 2

Dividing both sides by 2:

x = 1

So, the lesser number is 1 and the greater number is 8 times that, which is 8.

Therefore,

The numbers are 1 and 8.

The perimeter of the figure is 58 m.

To find the perimeter of the given figure we can divide the figure in three rectangles.

Rectangle 1:

Perimeter= 2 (l + w)

= 2(5 + 2)

= 2 x 7

= 14 m

Rectangle 2:

Perimeter= 2 (l + w)

= 2(5 + 1)

= 2 x 6

= 12 m

Rectangle 3:

Perimeter= 2 (l + w)

= 2(14 + 2)

= 2 x 16

= 32 m

So, the perimeter of the figure is

Answer:

The perimeter of the scale floor is 34 inches.

Step-by-step explanation:

To solve, we can set up fractions:

\(\frac{21}{7}=\frac{30}{x}\)

Cross multiply and you get:

21x = 210

Divide each side by 21:

x = 10

Since you are trying to find the perimeter of the floor, you can use this equation:

2w + 2l = p

Substitute to solve:

2 ( width = 10 )

2 ( length = 7 )

2 ( 7 ) + 2 ( 10 ) = p

14 + 20 = p

Step-by-step explanation:

Sum  of interior angles = 180·(n-2),

where n is the number of sides the polygon has

Sum = 180·(7-2)

Sum = 180·5

Sum = 900°

The result is roughly 4, as we may round 65 to the closest choice and get 64, which matches to response choice C.

The degree to which the data points in a data distribution or data collection deviate from the average value and from one another is virtually by definition the measure of variability.

We must first determine the average price of used automobiles sold at every dealership in order to determine the variance between the means in order to address this problem. After that, we can calculate the number of times the variation can be found in the difference by dividing the disparity between the averages by the variability.

By locating the middle of the price range displayed on the dot plots, we can calculate the mean cost of used cars sold for each dealership. The price range for dealership A is roughly $15,000 to $20,000, with $17,500 serving as the midpoint. The range for dealership B is roughly $16,000 to $21,000, with $18,500 serving as the midpoint.

The difference between the means is therefore $18,500 - $17,500 = $1,000.

When the difference is divided by the variability, the result is:

$1,000 ÷ ($1,538/100) = 100,000 ÷ 1,538 = 64.93

The variability is therefore nearly 65 times larger than the disparity between the means.

We must round our response to the closest choice since neither of the possible answers is close to 65. The result is roughly 4, as we may round 65 to the closest choice and get 64, which matches to response choice C.

Answer:

The first box : -4  the second one : 6

Step-by-step explanation:

subtract 7 from 3 for the first box, then add 10 to -4 for the second one.

The equations that can be used to determine the length of the room are:

y(y + 5) = 750

y²– 5y = 750

(y - 30) (y + 25) = 0

A rectangle is a two-dimensional object that has four sides and four right angles. The sides of a rectangle are known as the width and the length.  A rectangle has two diagonals of equal length which bisect each other at right angles.

Area of a rectangle = length x width

750 = y x (y - 5)

750 = y² - 5y

y² - 5y - 750 = 0

The factors of -750y² that add up to -5y are 25y and -30

(y² + 25y)(-30y - 750) = 0

y(y + 25) = 0

-30(y + 25) = 0

(y - 30) (y + 25) = 0
