Answer: Not necessarily. Dividing the pie chart into 5 equal sections might be a way to display categorical data if the number of categories is 5. However, dividing it into 5 sections might not be the best way to display the data if the number of categories is different than 5 or if any category has a significantly higher or lower proportion than the others. In this case, it may be more appropriate to use a different scale to display the correct ratio. It is important to consider data distribution and visualization clarity before choosing how to display categorical data.

The length of NP is 6.28 cm

A triangle is a two-dimensional geometric shape with three sides and three angles. It is one of the basic shapes in geometry and has many different properties that can be studied. Triangles can be classified into several different types based on the length of their sides and the size of their angles.

The most basic type of triangle is an equilateral triangle, which has three sides of equal length and three equal angles. Another common type of triangle is the right triangle, which has one right angle (90 degrees) and two other angles that add up to 90 degrees. Scalene triangles have no sides or angles of equal length, while isosceles triangles have at least two sides of equal length.

Triangles have many interesting and useful properties that can be used in geometry and other areas of mathematics. For example, the Pythagorean Theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side. This theorem can be used to find the length of a missing side in a right triangle.

To find angle P and angle M, we can use the fact that the sum of the angles in a triangle is 180 degrees.

angle P + angle M + 46 = 180

angle P + angle M = 134

Next, we can use the law of cosines to find angle P. Let's call the length of NP "x".

cos(angle P) = (MN² + MP² - x²) / (2 × MN × MP)

We can use the formula for cosine to solve for angle P:

angle P = arccos((MN² + MP² - x²) / (2 × MN × MP))

Substituting in the values for MN and MP:

angle P = arccos((4² + 7² - x²) / (2 × 4 × 7))

Next, we can use the Pythagorean theorem to find x:

x^2 = MN^2 + MP^2 - 2 * MN * MP * cos(angle P)

x^2 = 4^2 + 7^2 - 2 * 4 * 7 * cos(angle P)

x² = 49 - 56 × cos(angle P)

Substituting in the value we found for angle P:

x² = 49 - 56 × cos(arccos((4² + 7² - x²) / (2 × 4 × 7)))

Solving for x, we get:

x = sqrt(49 - 56 × cos(arccos((4² + 7² - x²) / (2 × 4 × 7))))

x = sqrt(49 - 56 × cos(arccos(33 / 28)))

x = √(49 - 56 × (33 / 28) / √(33² + 28²))

x = √(49 - 56 × 33 / 28 / √(33^2 + 28^2))

Finally, we can use the value we found for x to find angle M:

angle M = 134 - angle P

angle M = 134 - arccos((4² + 7² - x²) / (2 × 4 × 7))

So the final answers are:

angle P = arccos((4² + 7² - x²) / (2 × 4 × 7)) = 68.93 degrees

angle M = 134 - angle P = 65.07 degrees

length of NP = x = sqrt(49 - 56 × 33 / 28 / √(33² + 28²)) = 6.28 cm

1/4 min, 15 sec

Answer:

(a)

f(x) = 30, for x ≤ 200

f(x) = 0.03(x - 200) + 30, for x > 200

(b) $34.50

(c) 356

Step-by-step explanation:

Let x = number of minutes.

(a)

f(x) = 30, for x ≤ 200

f(x) = 0.03(x - 200) + 30, for x > 200

(b)

Here, x = 350, so x > 200.

f(x) = 0.03(x - 200) + 30

f(350) = 0.03(350 - 200) + 30

f(350) = 0.03(150) + 30

f(350) = 4.5 + 30

f(350) = 34.5

$34.50

(c)

f(x) = 0.03(x - 200) + 30

0.03(x - 200) + 30 = 34.68

0.03(x - 200) = 4.68

x - 200 = 156

x = 356

The speed of the cars are 50mph and 60mph

Let's call the speed of the slower car "x". The faster car is traveling at "x + 10 mph".

The total distance both cars travel is 660 miles, and the time it takes for them to meet is 6 hours.

Using the formula for distance = rate x time, we can set up the equation:

x * 6 + (x + 10) * 6 = 660

Expanding and simplifying, we get:

12x + 60 = 660

Subtracting 60 from both sides:

12x = 600

Dividing both sides by 12:

x = 50 mph

So the slower car is traveling at 50 mph and the faster car is traveling at 60 mph.

comment if u need explanation

Mr. Black was driving at 60 mph to his friend's house.

Let's call Mr. Black's speed to his friend's house "x".

The trip back took x - 20 mph, since he was driving 20 mph slower.

The trip back took 1 hour longer, so it took 2 + 1 = 3 hours.

Using the formula for distance = rate x time, we can set up the equation:

x * 2 = (x - 20) * 3

Expanding and simplifying, we get:

2x = 3x - 60

Subtracting 2x from both sides:

0 = x - 60

Adding 60 to both sides:

x = 60 mph

The area of the rectangle =  9x² +18x−16

What is the area of the rectangle?

The area of a rectangle is calculated by multiplying the height by the width. If the height of the rectangle is represented by h and the width is represented by w, then the area is given by:

A = h * w

In this case, the height of the rectangle is given as 3x - 2 yards, and the width is given as 3x + 8 yards. So, substituting these values into the formula:

A = (3x - 2) * (3x + 8)

A = (3x - 2)(3x + 8)

A = 9x² +18x−16

On solving the provided question, we can say that the inequality formed is 1 ≥ 2(3)-5 => 1 ≥ 1

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

The ordered pair is (3, 1)

Substitute (x, y)=(3, 1) in the given inequality, we get

Yes, this is correct. If you solve the first equation it equals the second equation.

Answer:

a) Let's call the length of a call "t" (in minutes). The cost of a call can be represented as follows:

C(t) = 0.99 if t <= 20

C(t) = 0.99 + 0.07(t - 20) if t > 20

b) The domain of the function is all non-negative real numbers (t >= 0), since a call can have any non-negative length in minutes. The range of the function is all non-negative real numbers, since the cost of a call can never be negative.

c) If a call lasts 12 minutes, then the cost would be 0.99:

C(12) = 0.99

d) If a call lasts 1 hour (60 minutes), then the cost would be:

C(60) = 0.99 + 0.07(60 - 20) = 0.99 + 0.07(40) = 0.99 + 2.80 = 3.79
