Find the surface area of the square pyramid shown. Label the net to help you.

I have to show work

**Answer: 40 inches squared**

Labels are in the pictures

**Step-by-step explanation:**

To find the surface area, find the area of each side.

Square (base) : side * side = 4*4 = 16

Triangle (sides) : (base * height)/2

Assuming each side is a isosceles triangle, the base 4/2 = 2

(2*6)/2 = 12/2 = 6

Since there are 4 triangles, we can multiply 6 by 4 to get the combined area. We then add the area of the square to get the final result.

6*4 + 16 = 24+16 = 40

Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV. He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV. Is Johnny making a valid inference about this population? (5 points)

a

Yes, it is a valid inference because his classmates make up a random sample of the students in the school

b

Yes, it is a valid inference because he asked all 26 students in his science class

c

No, it is not a valid inference because he asked all 26 students in his science class instead of taking a sample from his math class

d

No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

Based on the sample space, what is the probability of getting a total of 6? (5 points)

a. 5 over 36

Selected:b. 6 over 36This answer is incorrect.

c. 7 over 36

d. 8 over 36

**Answer:**

B. 6 over 36

**Step-by-step explanation:**

As we are given the sample space, the events that sum to 6 are:

{(1,5), (2,4), (3,3),(4,2),(5,1)}

Let n(S) be the number of items in sample space

n(S) = 36

Let E be the event the sum is 6

Then,

n(E) = 6

So,

P(Sum of two cubes is 6) = n(E) / n(S)

= 6/36

So, the correct answer is:

B: 6/36

B. 6 over 36

Cube Roots of Negative Numbers.

Thank you!♡

**Answer:The cube root of a negative number is a complex number because there is no real number that, when cubed, gives a negative result.**

**To find the cube root of -1, we can express it in exponential form as -1 = 1 * e^(iπ), where i is the imaginary unit and π is pi.**

**The cube root of -1 can be calculated by applying De Moivre's theorem, which states that (r * e^(iθ))^(1/n) = r^(1/n) * e^(iθ/n), where r is the magnitude and θ is the argument of the complex number.**

**For n = 3, the cube root of -1 becomes:**

**(-1)^(1/3) = (1 * e^(iπ))^(1/3) = 1^(1/3) * e^(iπ/3) = e^(iπ/3).**

**Therefore, the cube root of -1 is e^(iπ/3), which can also be expressed as cos(π/3) + i * sin(π/3).**

**In trigonometric form, the cube root of -1 is (√3/2) + i * (1/2).**

At a recent football game of 8,450 in attendance, 150 people were asked what they prefer on a hot dog. The results are shown.

Ketchup Relish Chili

54 36 60

Based on the data in this sample, how many of the people in attendance would prefer chili on a hot dog?

5,070

3,380

2,986

2,084

**Answer: 3,380**

**Step-by-step explanation: THIS IS MY GUESS. **

**Since we know that 150 people were surveyed, and only 60 wanted chili, we can write an equation to get the percentage of people who wanted chili as 60/150. We can simplify that to get 6/15 and then simplify again to get 2/5. 2/5 simplifies to 40% as a percentage. 40% of 8,450 (or 0.4 x 8,450) would be 3,380. **

Answer 3380

Explanation

We will find the ratio of 54 36 and 60 which is 9:6;10

So now total attendance is 8450.

So 8450 * 6 / 15= 3380

Explanation

We will find the ratio of 54 36 and 60 which is 9:6;10

So now total attendance is 8450.

So 8450 * 6 / 15= 3380

Work out the area of the trapezium

(some please help, i forgot how to do this )

Answer:

48cm

Step by step:

The area of a trapezoid can be found using the formula A=(1/2)(b1+b2)h, so we replace each variable with what is written on the trapezoid. A=(1/2)(7+9)(6), so once you simplify you get 48.

**Answer:**

The area of the **Trapezium **is **48cm²**.

**Step-by-step explanation:**

A **trapezium** has a pair of **Parallel** **Lines**.

Let’s mark the line that is on the **top** as A and the **bottom** one as B.

**Length** of **line A** *(Base 1) *= **7cm**

**Length** of **line B** *(Base 2)* = **9cm**

**Height** of **Trapezium** = **6cm**

**Area **of **Trapezium** *(Formula) *=** {( Base 1 + Base 2 ) / 2} * Height**

** **= **{( 7cm + 9cm ) / 2} * 6cm**

** **= **( 16cm / 2 ) * 6cm**

** **= **8 cm * 6cm**

** **= **48cm²**

The area of the **Trapezium **is **48cm²**.

100 PTS *MIDDLE SCHOOL 7th GRADE***** HELP PLEASE!

**Answer: **x=108 degrees

**Step-by-step explanation:**

Since ST is a straight line, it measures 180 degrees.

This means that

x+(2/3)x=18

The simplified version is 5x/3=180. Now, we multiply both sides by 3. The equation becomes 5x=540 you would divide 5 by both sides which is ultimately x=108.

**Answer:**

x=108 degrees

**Step-by-step explanation:**

We know that since ST is a line, it equals a total of 180 degrees.

Let's write an equation:

[tex]180=x+\frac{2}{3}x[/tex]

*simplify*

[tex]180=\frac{5}{3} x[/tex]

*divide both sides by 5/3*

108=x

So, x=108 degrees.

9. What is the area of a square with a perimeter of 44 mm?

10. What is the area of a square with a perimeter of 55 cm

**Answer:**

**Step-by-step explanation:**

To find the area of a parallelogram, multiply the base by the height:

Area = base x height

Area = 6.3 m x 27.3 m

Area = 171.99 m²

To find the height of a rectangle, divide the area by the base:

Height = Area / Base

Height = 420.92 mm² / 27.4 mm

Height ≈ 15.35 mm

The perimeter of a rectangle is given by 2 times the sum of the base and height:

Perimeter = 2(base + height)

133.2 mm = 2(30.6 mm + height)

133.2 mm = 61.2 mm + 2 height

2 height = 133.2 mm - 61.2 mm

2 height = 72 mm

Height = 72 mm / 2

Height = 36 mm

To find the height of a parallelogram, divide the area by the base:

Height = Area / Base

Height = 645 m² / 61 m

Height ≈ 10.57 m

The perimeter of a parallelogram is the sum of all its sides:

Perimeter = 2(base + side length)

Perimeter = 2(32 cm + 34 cm) + 2(height)

Perimeter = 2(66 cm) + 2(19 cm)

Perimeter = 132 cm + 38 cm

Perimeter = 170 cm

To find the area of a parallelogram, multiply the base by the height:

Area = base x height

Area = 40 mm x 18 mm

Area = 720 mm²

The perimeter of a rectangle is given by the formula: Perimeter = 2(base + height)

Perimeter = 2(7.9 m + 8.8 m)

Perimeter = 2(16.7 m)

Perimeter = 33.4 m

To find the height of a rectangle, divide the area by the base:

Height = Area / Base

Height = 354 cm² / 23 cm

Height ≈ 15.39 cm

The perimeter of a square is 4 times the length of one side. Since the perimeter is given as 44 mm, we can divide it by 4 to find the length of one side:

Side length = Perimeter / 4

Side length = 44 mm / 4

Side length = 11 mm

To find the area of a square, multiply the side length by itself:

Area = side length x side length

Area = 11 mm x 11 mm

Area = 121 mm²

The perimeter of a square is 4 times the length of one side. Since the perimeter is given as 55 cm, we can divide it by 4 to find the length of one side:

Side length = Perimeter / 4

Side length = 55 cm / 4

Side length = 13.75 cm

To find the area of a square, multiply the side length by itself:

Area = side length x side length

Area = 13.75 cm x 13.75 cm

Area ≈ 189.06 cm²
