Step-by-step explanation:

Hello mate ☺️,

We know that m < 2 = 96°, as,

\(m < 5 = 96°\)(Alternate angles are equal)

Now we know that m < 5 = 96°, so,

\(→ m < 5 + m < 8 = 180°\)(Linear Pair angles are supplementary)

\(→ 96° + m < 8 = 180°\)

\(→ m < 8 = (180 - 96)°\)

\(→ m < 8 = 84°\)

Therefore, m<5 = 96° & m<8=84°

Answer: 8 girls

Step-by-step explanation:

The team is split into groups that have the same ratio as the whole team.

This means that every group must obey this ratio:

12 girls  :   18 boys

At the lowest form (dividing both sides by 6), the ratio is:

2    :    3

Every group must therefore be in a ratio of; 2 : 3.

In a team group that has 12 boys, the number of girls is:

2    :    3

x    :    12

3x = 24

x = 24 / 3

x = 8 girls

The lateral area and the total area of each solid is:

Solid 1: Lateral area: A = 120 km², Total area: A = 168 km²

Solid 2: Lateral area: A = 317.34 mm², Total area: A = 389.34 mm²

Solid 3: Lateral area: A = 109.44 mm², Total area: A = 168.94 mm²

Solid 4: Lateral area: A = 62.354 m², Total area: A = 90.067 m²

Solid 5: Lateral area: A = 960 cm², Total area: A = 1060 cm²

Solid 6: Lateral area: A = 1728 cm², Total area: A = 2052 cm²

Herein we find six cases of solids, whose lateral area and total area must be determined. The lateral area is the sum of the areas of all lateral faces and the total area is the sum of the lateral area and the sum of the bases. The area of each face can be found by means of the following formulas:

Triangle (classic formula)

A = 0.5 · b · h

Triangle (equilateral - Heron's formula)

A = (√3 / 4) · a²

Triangle (Heron's formula)

A = √[(a² + b² + c²)² - 2 · (a⁴ + b⁴ + c⁴)]

Rectangle

A = b · h

Where:

Case 18 (Lateral area)

A = (6 km) · (5 km) + (8 km) · (5 km) + (10 km) · (5 km)

A = 30 km² + 40 km² + 50 km²

A = 120 km²

Case 19 (Total area)

A = 120 km² + 2 · 0.5 · (6 km) · (8 km)

A = 120 km² + 48 km²

A = 168 km²

Case 20 (Lateral area)

A = 2 · (12.9 mm) · (4.8 mm) + 2 · (7.5 mm) · (12.9 mm)

A = 317.34 mm²

Case 21 (Total area)

A = 317.34 mm² + 2 · (4.8 mm) · (7.5 mm)

A = 389.34 mm²

Case 22 (Lateral area)

A = 2 · (3.8 mm) · (11.9 mm) + 2 · (2.5 mm) · (3.8 mm)

A = 109.44 mm²

Case 23 (Total area)

A = 109.44 mm² + 2 · (2.5 mm) · (11.9 mm)

A = 168.94 mm²

Case 24 (Lateral area)

A = 3 · 0.5 · (8 m) · (3√3 m)

A = 62.354 m²

Case 25 (Total area)

A = 62.354 m² + (√3 / 4) · (8 m)²

A = 62.354 m² + 27.713 m²

A = 90.067 m²

Case 26 (Lateral area)

A = 4 · √[[(10 cm)² + (13 cm)² + (13 cm)²]² - 2 · [(10 cm)⁴ + (13 cm)⁴ + (13 cm)⁴]]

A = 960 cm²

Case 27 (Total area)

A = 960 cm² + (10 cm)²

A = 960 cm² + 100 cm²

A = 1060 cm²

Case 28 (Lateral area)

A = 4 · √[[(18 cm)² + (15 cm)² + (15 cm)²]² - 2 · [(18 cm)⁴ + (15 cm)⁴ + (15 cm)⁴]]

A = 1728 cm²

Case 29 (Total area)

A = 1728 cm² + (18 cm)²

A = 2052 cm²

Perfect roots are not irrational numbers, but rational numbers.

Step-by-step explanation:

We can look at exponents here.

3² = 9

4² = 16

The opposites of these exponents, or square roots, would be rational whole numbers:

√16 = 4

√9 = 3

√4 = 2

Answer:

-18

Step-by-step explanation:

Let x be our number. First we have to write our equation.

The product of a number and -8 is represented as -8x (-8 multiplied by x). Remember that 'product' signifies multiplication.

The result is eight times the sum of x and 36. This is represented as 8(x + 36). We add x and 36 first because 8 has been multiplied by the sum of those two numbers.

So our equation is:

-8x = 8(x + 36)

We can now solve for x. First, expand the bracket.

-8x = 8x + 288

Next, subtract 8x from both sides. This will give us only one term containing x, which will make it easier to solve.

-8x - 8x = 8x + 288 - 8x

-16x = 288

Divide both sides by -16

x = -18

Answer:

<B = 32°

c = 9.43

Step-by-step explanation:

To find the measure of <B, add up the measures of the two angles that you know and subtract from 180°.

58° + 90° = 148°

180° - 148° = 32°

The measure of <B is 32°.

To find the length of side c, use the Pythagorean Theorem.

a² + b² = c²

5² + 8² = c²

25 + 64 = c²

89 = c²

c = √89

c = 9.433981132 ⇒ 9.43 (rounded to two decimal places)

The length of side c = 9.43.

Answer: \(x=4\sqrt{5}\)

Step-by-step explanation:

The explanation is attached below.

Height =9.7ft

Radius=7.6 feet

Let's begin by finding the mean of the data

Mean = 48.9

Next, we calculate the absolute value of the difference between each data value and the mean, we have:

|data value – mean|

|46 - 48.9| = 2.9

|47 - 48.9| = 1.9

|56 - 48.9| = 7.1

|48 - 48.9| = 0.9

|46 - 48.9| = 2.9

|52 - 48.9| = 3.1

|57 - 48.9| = 8.1

|52 - 48.9| = 3.1

|45 - 48.9| = 3.9

Next, we sum up the absolute values of the differences (from above) & divide by the number of data values, we have:

MOD = 8 (to the nearest whole number)

Centimeters are converted into grams when comparing the two units of mass in order to have accuracy and avoid confusion in measurement, we need to convert one unit to another.

Because using grams makes most commonly occurring masses into large (and long) numbers, which is inconvenient. Some people use cgs (centimeter-gram-second) units and others use SI (meter-kilogram-second), so it's not really true that the kg is the basic unit for mass.

To make a comparison, we should convert the measurements to the same units. The conversion between different types of units makes sense. A cm3 equals an ml. This makes changing distance and volume easy to understand and calculate.

Here is the equivalent ratio:

To make the ratios equivalent, you need to find an equivalent fraction.

In the given statement is:

You conduct a survey of your small town about having a town wide gargae sale. of those surveyed, 56% are in favor and 44% are opposed. the actual percent could be 5% more or 5% less than the acquired results.

Using the absolute value function, we have that:

A. The least percentage is of 39% and the greatest is of 49%.

B. Since the greatest percentage is below 50%, the statement conflicts with the survey data.

What is the absolute value function?

The absolute function is defined by:

It measures the distance of a point x to the origin.

For this problem, the difference between the percentage of opposed and 44% can be of at most 5%, hence the absolute value equation is:

Joint Distribution of x and y is 25.

Joint Distribution is based on joint probability, which can be simply defined as the probability of two events happening together.

We know the formula for joint distribution

F(x,y) = P(X ≤ x and Y ≤ y) = ∑∑p(xi,yi)

Here x is the number of aces and y is the number of kings in a poker hand.

That means x can take values from 0 to 4 and y can take values from 0 to 4.

∴ F(x,y) = P(X ≤ 4 and Y ≤ 4)

⇒ F(x,y) = p(0,0) + p(0,1) + p(0,2) + p(0,3) + p(0,4) + p(1,0) + p(1,1) + p(1,2) + p(1,3) + p(1,4) + p(2,0) + p(2,1) + p(2,2) + p(2,3) + p(2,4) + p(3,0) + p(3,1) + p(3,2) + p(3,3) + p(3,4) + p(4,0) + p(4,1) + p(4,2) + p(4,3) + p(4,4).

To find all these values we will construct a table as follows;

P(x,y)           Y=0      Y=1         Y=2      Y=3    Y=4

X=0              0          1/4          1/2        3/4       1      

X=1               1/4        1/2        3/4         1        5/4

X=2             1/2         3/4         1            5/4     3/2

X=3             3/4          1          5/4         3/2      7/4      

X=4               1          5/4         3/2       7/4       2

Now the joint distribution will become,

F(x,y) = 0 + 1/4 + 1/2 + 3/4 + 1 + 1/4 + 1/2 + 3/4 +1  + 5/4 + 1/2 + 3/4 + 1 + 5/4 + 3/2 + 3/4 + 1 + 5/4 + 3/2 + 7/4 + 1 + 5/4 + 3/2 + 7/4 + 2

F(x,y) = 25

Therefore the joint distribution of x and y is 25.

Let's call L the length of the rectangle and W the width of the rectangle

We know the length is 3 times its width:

L = 3W

The area of a rectangle is:

A=L*W

Substituting the condition above, we have:

A = (3W)*W

Operating:

We know the area is 147 yd^2, so we equate:

Solve for W:

Taking the square root on both sides:

The width is 7 yd. Now we can easily find the length:

L=3W=3*7=21 yd

Finally, we calculate the perimeter of the rectangle. Recall the perimeter is calculated with the formula:

P=2L+2W

Thus, using the known values:

P=2*21+2*7=42 + 14 = 56 yd

The perimeter of the rectangle is 56 yd

Notice the domain for both function is all real numbers.

So if we either add, subtract, multiply, or compose the functions, the domain will be all real numbers.

The equation relating x, y, and z is:

z = 0.5 * x * y.

In the given problem, the relationship between x, y, and z can be expressed by the equation z = k * x * y, where k represents the constant of proportionality. By substituting the values of x = 4 and y = 5, when z is equal to 10, we can determine the value of the constant of proportionality, k, and further define the relationship between the variables.

To find the constant of proportionality, we substitute the known values of x = 4, y = 5, and z = 10 into the equation z = k * x * y. This gives us the equation 10 = k * 4 * 5. By simplifying the equation, we have 10 = 20k. To isolate k, we divide both sides of the equation by 20, resulting in k = 0.5. Therefore, the equation relating x, y, and z is z = 0.5 * x * y, meaning that z is directly proportional to the product of x and y with a constant of proportionality equal to 0.5.
