What is the mean of the dataset (10, 5, 7, 9, 5, 18)?

[tex]\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}[/tex]

Mean [tex]\rightarrow[/tex] 9

[tex]\blue{\textsf{\textbf{\underline{\underline{How to solve:-}}}}[/tex]

First, add all the numbers together:-

10+5+7+9+5+18

[tex]\textsf{54}[/tex]

Now divide by how many numbers there are (6):-

54:6=9

So the mean of the dataset is 9.

Good luck.

Use the net to find the surface area of the regular pyramid. (OPEN TO SEE PICTURE) PLS ITS URGENT

Answers

By the combined area of the triangles and the base. The total surface area of the regular pyramid would be 197.1 ft^2.

What is the area of the triangle?

The area of the triangle is defined as the product of half the base and the height of the triangle.

The area of the triangle = 1/2 x b x h

we need to find the areas of each triangle in the pyramid.

The area of base = 15.6

The area of each outer triangle = 1/2 x 9 x 12

= 54

There are 3 triangle

3 x 54 = 162

The total area will become

162 + 35.1

= 197.1

Therefore, The total surface area of the regular pyramid = 197.1 ft^2

equation that shows 3 less than the product of 4 and m

Answers

The equation that shows 3 less than the product of 4 and m is 3 < 4m

Formation of equation

Formation of equation is a means of transforming statements into equations

The product of 4 and m is 4m

If 3 is less than the product of 4 and m, this is expressed as:

3 < 4m

Divide both sides by 4

3/4 < m

m > 3/4

Hence the equation that shows 3 less than the product of 4 and m is 3 < 4m

An Olympic pool is rectangular with a length of 50 meters. Ms Burri wants to fit an Olympic pool in her backyard but doesn't have enough room so she plans to build a similar pool with a length of only 30 meters.

a. She wants to replace the pool deck around her new smaller pool. What is the ratio of the perimeter of the Olympic pool to the new smaller pool?

b. The area of the olympic pool is 1,2500 meters squared. If she were to buy a pool cover to fit her brand new smaller pool, what would the area be?

Answers

Perimeter of older

2(50+W)100+2W

Perimeter of newer

2(30+W)60+2W

As w is constant cancel it

Ratio

100/605/3

Ratio of area is also same

5/3=12500/x5x=37500x=37500/5x=7500m²

Answer:

See below ~

Step-by-step explanation:

Finding perimeter of Olympic pool and regular pool :

P (olympic) = 2(l + w) = 2(50 + w) = 2w + 100P (regular) = 2(l + w) = 2(30 + w) = 2w + 60

Taking the ratio :

2w + 100 : 2w + 60100 : 605 : 3

Using ratios to find area of regular :

5 : 3 = 12,500 : aa = 12500/5 x 3 = 2500 x 3a = 7,500 m²

Answer:

25/8 = 3.125

Step-by-step explanation:

Answer:

5 × 5 ÷ 8 = 3 ¹/₈

Step-by-step explanation:

Using the order of operations we need to work from left to right.

Therefore we should carry out the multiplication first.

5 × 5 means "5 lots of 5"

⇒ 5 × 5 = 5 + 5 + 5 + 5 + 5 = 25

Now we need to divide 25 by 8.

8 + 8 + 8 = 24

Therefore, 8 goes into 25 three times with a remainder of 1.

So, 5 × 5 ÷ 8 = 3 ¹/₈

What is the formula for a surface area of a rectangular prism?

Answers

Answer:

[tex]\boxed{\text{SA} = 2(\text{L} \text{W}) + 2(\text{L} \text{H}) + 2(\text{B} \text{H})}[/tex]

Step-by-step explanation:

We know that the surface area is the sum of the area of the prism's faces.

It should be noted that the area of any face is equal to the area of its opposite face. Thus, we get the following equation for the surface area:

[tex]\implies\text{SA = 2(} \text{Area of rectangle}_{1} ) \ + \ \text{2}(\text{Area of rectangle}_{2} ) \ + \ \text{2}(\text{Area of rectangle}_{3} )[/tex]

A model has been drawn of the rectangular prism. (image)

Let the dimensions (length, width, and height) of the prism be known as L, B, and H respectively. Then, we get the following:

[tex]\implies \text{SA} = 2(\text{L} \times \text{W}) + 2(\text{L} \times \text{H}) + 2(\text{B} \times \text{H})[/tex]

[tex]\implies \boxed{\text{SA} = 2(\text{L} \text{W}) + 2(\text{L} \text{H}) + 2(\text{B} \text{H})}[/tex]
