The perimeter of triangle MNO is given as follows:

17.2 in.

Similar triangles are triangles that share these two features listed as follows:

Applying the Pythagorean Theorem, the side length x of triangle MNO is given as follows:

x² = 4² + 6²

x² = 52

x = square root of 52

x = 7.2 in.

Hence the perimeter of triangle MNO is given as follows:

4 + 6 + 7.2 = 17.2 in.

Answer:

the probability of neither showing a multiple of 3 nor a multiple of 4 on the second die is 17/36, or approximately 0.4722

Step-by-step explanation:

To find the probability of neither showing a multiple of 3 nor a multiple of 4 on the second die, we need to first determine the sample space of possible outcomes.

The sample space of rolling two dice is given by all possible pairs of numbers from 1 to 6, which has a total of 6 x 6 = 36 possible outcomes.

Out of these 36 possible outcomes, there are 12 outcomes where the second die shows a multiple of 3 (namely 3, 6, and 9), and 9 outcomes where the second die shows a multiple of 4 (namely 4 and 8).

However, we must note that there are two outcomes where the second die shows both a multiple of 3 and a multiple of 4, namely (3,4) and (6,4). We need to subtract these two outcomes from our total count.

Therefore, the number of outcomes where the second die shows a multiple of 3 or a multiple of 4 or both is 12 + 9 - 2 = 19.

The number of outcomes where the second die does not show a multiple of 3 or a multiple of 4 is the complement of the above count, which is 36 - 19 = 17.

Therefore, the probability of neither showing a multiple of 3 nor a multiple of 4 on the second die is 17/36, or approximately 0.4722.

The perimeter of the figure shown on the coordinate plane is 56 units.

Perimeter of a straight sided figures or objects is the total length of it's boundary.

Given is a figure.

Perimeter of a figure is the total length of the boundary.

We have to find the length of each of the sides and then add it to get the perimeter.

Each line on the coordinate plane represents 2 units.

Perimeter adding the sides from the bottom, we get,

Perimeter = 2 + 3 + 11 + 8 + 4 + 4 + 9 + 15

Answer:

Step-by-step explanation:

The correct answer is A.

In the context of this situation, the slope of -6.2 means that the temperature drops 6.2 degrees for every hour that passes. The negative sign indicates that the temperature is decreasing over time.

The y-intercept of 64 means that at hour 0 (the start of recording data), the temperature was 64 degrees. This is the initial value of the temperature, before any time has passed.

The slope and y intercept describes that

The slope applied to this situation is the temperature drops 6.2 degrees per hour. The y-intercept means at hour 0 (start of recording data), it was a temperature of 64 degrees.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have,

The line of best fit with the equation y = -6.2x + 64, where x represents the hour and y represents the temperature.

As, we know that the slope shows the rate of change of one quantity with respect to another quantity.

Here, the slope -6.2 tells us that the  temperature drops 6.2 degrees per hour.

and, the y intercept tells us that at 0 hour the temperature is 64 degree.

Step-by-step explanation:

Part A:

The area covered by a circle is given by the formula:

A = πr^2

where r is the radius of the circle.

For two-way radio A, the radius is 3 miles. So we have:

A = π(3)^2

A ≈ 28.27 square miles

Therefore, two-way radio A covers approximately 28 square miles.

Part B:

For two-way radio B, the radius is 6.44 kilometers. However, the formula for the area of a circle uses the squared value of the radius, so we need to square 6.44:

A = π(6.44)^2

A ≈ 130.23 square kilometers

Therefore, two-way radio B covers approximately 130 square kilometers.

Part C:

To compare the two areas, we need to convert the area covered by two-way radio A to kilometers:

1 mile = 1.61 kilometers

So 3 miles is equivalent to:

3 miles x 1.61 kilometers/mile = 4.83 kilometers

The area covered by two-way radio A in square kilometers is:

A = π(4.83)^2

A ≈ 73.03 square kilometers

Comparing the areas, we see that two-way radio B covers the larger area.

Part D:

The scale factor relationship between the radio coverages is the ratio of their radii. Using the given conversion factor, we can convert the radius of two-way radio A to kilometers:

3 miles x 1.61 kilometers/mile = 4.83 kilometers

So the scale factor relationship is:

4.83 km (radius of two-way radio A) / 6.44 km (radius of two-way radio B)

= 0.75

This means that the coverage area of two-way radio B is approximately 0.75 times the coverage area of two-way radio A.

Given that A couple of two-way radios were purchased from different stores. Two-way radio A can reach 3 miles in any direction. Two-way radio B can reach 6.44 kilometers in any direction.

A) two way radio A can cover 28 square miles. (using area of circle)

B) two way radio B can cover 132 square kilometer.  (using area of circle)

C) Area of coverage of radio B is more.

D) Using the radius of each circle, the scale factor relationship between the radio coverages of A and B is 3:4.

Area of a circle is given by the formula [tex]\pi r^2[/tex].

A) radius of radio A = 3 miles

Area of coverage = [tex]\pi r^2 = 3.14 *3*3 = 28.26[/tex] sq miles

B) radius of radio B =  6.44 km

Area of coverage = [tex]\pi r^2 = 3.14 *6.44*6.44 = 130.22[/tex] sq km

C) 1 mile = 1.61 km

1 sq mile = 1.61 km * 1.61 km = 2.5921 sq km

Area of coverage of radio A = 28.26 sq miles = 28.26 *2.5921 = 73.25 sq km

On comparison, area of coverage of radio B is more.

D) 1 mile = 1.61 km

radius of radio A = 3 * 1.61 = 4.83 km

scalar factor relationship between radio A and B = [tex]\frac{4.83}{6.44} = 3:4[/tex]

Answer:

360

Step-by-step explanation:

x*60/100=216

60x=21600

x=21600/60

x=360

360 students are thee in Milton Middle School.

Number of girls in Milton Middle School = 216

Percentage of girls in Milton Middle School = 60%

From the above information we can know that 216 = 60% of Milton Middle School.

1% of students in the school = 216/60

                                                 = 3.6

100% of students in the school = 3.6 * 100

                                                      = 360 students

Total number of students in Milton Middle School = 216/60 * 100

                                                                                       = 216/6 * 10

                                                                                       = 36 * 10

                                                                                        = 360 students

Answer: To determine which fraction and decimal cards have the same value, we can convert each fraction to a decimal and then compare them to the decimal cards:

2/3 = 0.666... (repeating)

6/8 = 0.75

5/4 = 1.25

5/6 = 0.833... (repeating)

0.6 repeating = 0.666... (repeating)

1.5 = 1.5

0.75 = 0.75

1.3 repeating = 1.333... (repeating)

1.25 = 1.25

0.83 = 0.83

0.8 = 0.8

0.83 repeating = 0.833... (repeating)

1.2 = 1.2

0.67 = 0.67

1.3 = 1.3

1.33 = 1.33

From this list, we can see that Bill can choose the following two cards that have the same value:

2/3 and 0.666... (repeating)

0.6 repeating and 0.666... (repeating)

Step-by-step explanation:

Bill has a range of card pairs that all have the same value at his command. The fraction card 2/3 and the decimal card 0.67 are one such pair because both cards show the value of two-thirds. The fraction card 6/8 (which may be written as 3/4) as well as the decimal card 0.75 are another pair that could be used as both of them reflect the value of three-quarters.

Since both cards show the value of five-sixths, Bill may either select the fraction card 5/6 and the repeating decimal card 0.83 repeating. The fraction card 1.25 and the decimal card 1.25 are another pair that may coexist as both of them represent the sum of one and one-quarter.

Also, Bill has the choice to pick either the fractional card 0.75 or the decimal card 0.75, both of which denote the value of three-fourths. He might also select the decimal card 1.33, which reflects the amount of one and one-third, and the fraction card 1.3 repeating, which is similar to 4/3.

Bill has a choice of card pairs to select from, all of which reflect the same number in both fractional and decimal form.
