The lengths are congruent and the widths are congruent.

Answer: Rectangle (4 sided polygon)

Step-by-step explanation:

The length and breadth in both triangles are equal which can also be said to be congruent. Adding the two triangles since they are both equal would result in a rectangular polygon (Rectangle)

Answer:

a) 35%

b) 19 minutes

Step-by-step explanation:

The graph for this question is attached in the image below.

Part a) Percent of calls that lasted 30 minutes or  more

As seen in the graph, the x-axis represent the duration of the call in minutes and y-axis represent the cumulative frequency of the calls.

From the graph we can see that the cumulative frequency against the point 30 minutes is about 65%. This means, 65% of the calls lasted for less than 30 minutes.

Since, out of 100%, 65% of the calls lasted for less than 30 minutes, the percentage of call that lasted for 30% or more would be:

100% - 65% = 35%

This means, 35% of calls lasted 30 minutes or  more.

Part b) The interquartile range (IQR) of the  distribution.

Interquartile range is defined as the difference of the 3rd Quartile and the 1st Quartile.

3rd Quartile is the point, below which 75% of the data values are present.

1st Quartile is the point, below which 25% of the data values are present.

So, from the cumulative frequency graph we have to look for the values on time axis against the cumulative frequency of 25% and 75%.

The amount of time against 25% cumulative frequency is approximately 13 minutes.

So, 1st Quartile = 13 minutes

The amount of time against 75% cumulative frequency is approximately 32 minutes.

So, 3rd Quartile = 32 minutes

Therefore,

IQR = 3rd Quartile - 1st Quartile

IQR = 32 - 13

IQR = 19 minutes

The interquartile range (IQR) of the  distribution is 19 minutes.

Answer:

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

Step-by-step explanation:

Let

x -----> number of pages that Polina read

y ----> number of pages that Marcus read

we know that

x+y=108 ----> equation A

x=5y -----> equation B

substitute equation B in equation A and solve for y

[tex]5y+y=108\\6y=108\\y=18[/tex]

Find the value of x

[tex]x=5y -----> x=5(18)=90[/tex]

therefore

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

[tex]\((f \cdot g)(x) = 2x^3 + 8x^2 - 2x - 20 \)[/tex].

To find [tex]\((f \cdot g)(x)\)[/tex], you need to multiply the functions \(f(x)\) and \(g(x)\).

Given:
[tex]\[ f(x) = x^2 + 2x - 5 \]\[ g(x) = 2x + 4 \]To find \( (f \cdot g)(x) \), multiply \( f(x) \) and \( g(x) \):\[ (f \cdot g)(x) = f(x) \cdot g(x) \]\[ (f \cdot g)(x) = (x^2 + 2x - 5) \cdot (2x + 4) \][/tex]

Now, use the distributive property to expand the expression:

[tex]\[ (f \cdot g)(x) = 2x^3 + 4x^2 + 4x^2 + 8x - 10x - 20 \]\[ (f \cdot g)(x) = 2x^3 + 8x^2 - 2x - 20 \][/tex]

So, [tex]\((f \cdot g)(x) = 2x^3 + 8x^2 - 2x - 20 \)[/tex].

Answer: 2

Step-by-step explanation:

First, set up a proportion based on the amount of square meters over the number of cloaks he can make:

21/6 = 7/x

Cross multiply to get your next proportion and result with this:

21x = 42

Divide both sides by 21 (always divide the side with the variable):

21x/21 = 42/21

Cancel out the 21 (it's being divided by 21 so that makes it equivalent to 1 so you wind up with just x)

x = 2

Answer: 2

Step-by-step explanation:

Given : Harry needs 21 square meters of fabric for every 6 wizard cloaks he makes.

Using Unitary method , The number of cloaks can be made in 1 square meter fabric will be :-

[tex]6\div21=\dfrac{6}{21}=\dfrac{2}{7}[/tex]

Now , the number of cloaks made in 7 square meters of fabric will be :-

[tex]\dfrac{2}{7}\times7=2[/tex]

Hence, the number of cloaks made in 7 square meters of fabric =2

Geometry unit 1 lesson 1 typically covers basic understandings, vocabulary, and objectives related to geometry, such as points, lines, angles, and shapes.

Explanation:

In geometry, unit 1 lesson 1 typically covers basic understandings, vocabulary, and objectives related to geometry. Students learn about concepts such as points, lines, angles, and shapes. They also explore properties and relationships between geometric figures.

For example, students might learn that a point represents a specific location in space, a line is a straight path with no endpoints, and an angle is formed by two rays with a common endpoint.

By studying geometry, students develop spatial reasoning skills and learn to apply geometric principles in problem-solving situations.

To solve for F in the conversion formula, subtract 273.15, multiply by ([tex]\frac{5}{9}[/tex]), and add 32. The freezing point of water in Fahrenheit is 32 °F. Liquid nitrogen is colder than dry ice.

Solving the Temperature Conversion Formula

To solve the formula K = [tex]\frac{9}{5}[/tex][F-32] + 273.15 for F (Fahrenheit), we will isolate F in the equation. Here is the step-by-step process:

Subtract 273.15 from both sides: K - 273.15 = [tex]\frac{9}{5}[/tex][F - 32]

Multiply both sides by [tex]\frac{5}{9}[/tex] to get: F - 32 = (K - 273.15) × [tex]\frac{5}{9}[/tex]

Add 32 to both sides to solve for F: F = (K - 273.15) × [tex]\frac{5}{9}[/tex] + 32

Converting Kelvin to Fahrenheit

The freezing point of water is 273.15 Kelvin. To find this temperature in Fahrenheit:

F = (273.15 - 273.15) × [tex]\frac{5}{9}[/tex] + 32 = 32 °F

Comparing Temperatures

Dry ice has a temperature of -78°C, which is equivalent to -108.4°F. Liquid nitrogen boils at 77 K, which is about -196°C or -320.8°F. Therefore, liquid nitrogen is colder than dry ice.

Answer:

The graph of f(x) is shifted up 50 units

The graph of f(x) is shifted right 10 units

The graph of f(x) is reflected over the x-axis

Step-by-step explanation:

we have

[tex]f(x)=x^{2}[/tex]

This is a vertical parabola open upward

The vertex is a minimum

The vertex is the origin (0,0)

[tex]g(x)=-5x^{2}+100x-450[/tex]

This is a vertical parabola open downward

The vertex is a maximum

The first thing to note is that fx) is a parabola that opens up and g(x) opens down, so a reflection across the x-axis must have been applied.

Find the vertex of g(x)

Convert to vertex form

[tex]g(x)=-5x^{2}+100x-450[/tex]

Complete the square

[tex]g(x)=-5(x^{2}-20x)-450[/tex]

[tex]g(x)=-5(x^{2}-20x+100)-450+500[/tex]

[tex]g(x)=-5(x^{2}-20x+100)+50[/tex]

[tex]g(x)=-5(x-10)^{2}+50[/tex]

The vertex is the point (10,50)

so

To translate the vertex of (0,0) to (10,50)

The rule of the translation is

(x,y) ------> (x+10,y+50)

That means ----> The translation is 10 units at right and 50 units up

therefore

The transformations are

The graph of f(x) is shifted up 50 units

The graph of f(x) is shifted right 10 units

The graph of f(x) is reflected over the x-axis

Answer: A rectangles angles are always equal.

Step-by-step explanation:

Suppose you have a rectangle, four sides, two pairs of parallel lines. in order to be a rectangle, the quadrilateral has to have equal angles, similar to a square, if they didn't, they could be a trapezoid, which is not a rectangle, because it only has one pair of parallel lines.

Hope this helps!

Answer:

x = 6

Step-by-step explanation:

Distribute the 4:

4x + 16 + 2x=52

Add similar variables (4x + 2x)

6x + 16 = 52

Move the 16 to the other side by subtracting 16 from both sides

6x = 36

Divide both sides by 6 to get rid of the 6 in front of the x

x = 6

Answer:

x=6

Step-by-step explanation:

4(x+4)+2x=52

distribute

4x+16+2x=52

combine like terms

6x+16=52

subtract 16 from both sides

6x=36

divide by 6

x=6

Answer:

f(x) is greater.

Step-by-step explanation:

if you replace the x on f(x)=3x+1 with the 3 for x=3 its 3×3+1. 3 times three is 9 plus 9 with one is 10, and the line hits 6.9

The  function that has a greater value when x = 3 is option A: f(x) is greater.

The function [tex]\(f(x) = 3x + 1\)[/tex] is a linear function with a slope of 3 and a y-intercept of 1. The function[tex]\(g(x)\)[/tex] is not explicitly provided in your question, so we don't have information about its slope or intercept.

To determine which function has a greater value when x = , we need to evaluate both functions at x = 3 and compare their values.

So, when one replace the x on f(x)=3x+1 with the 3 for x=3 its 3×3+1. 3 times three is 9 plus 9 with one is 10, and the line hits 6.9
