Answer:

Lateral area of the cone = 4,712 m (Approx)

Step-by-step explanation:

Given:

Height of cone (h) = 40m

Radius (r) = Diameter / 2 = 60 / 2 = 30m

Find:

Lateral area of the cone = ? ?

Computation:

Slant\ height(l) =\sqrt{h^2+r^2} \\\\ Slant\ height(l) =\sqrt{40^2+30^2} \\\\ Slant\ height(l) =\sqrt{1,600+9,00} \\\\ Slant\ height(l) = 50m

Lateral\ area\ of\ the\ cone =\pi rl\\\\ Lateral\ area\ of\ the\ cone = \frac{22}{7}(30)(50)\\\\Lateral\ area\ of\ the\ cone= 4,712 (Approx)

Step 1: Distribute. On the right side, you should get =2x-4
Step 2: Add all common bases. You should get 4x-5 on the left side
Step 3: Add on each side. For example, add five to each side of the equation. Your equation should look like this; 4x= 2x+1
Step 4: Subtract each x number by 2x. Your equation should be; 2x=1
Step 5: Divide each side by two. Your answer should be x=1/2 or x=0.5

PART - A : tent - 1 volume = 400 cubic ft

Tent -2 volume = 384 cubic ft.

PART - B : I recommend Joe to make the tent -1 with base 10x10 ft. as it has more volume

<u>Step-by-step explanation:</u>

PART - A:

tent 1 :

 Base = 10 x 10ft

 Height= 12 ft

 Volume = (1/3) (10x 10) (12)

 = (1/3) (100) (12)

= 400 cubic ft.

Tent 2:

 Base = 12 x 12 ft

 Height= 8 ft.

 Volume = (1/3) (12 x 12) (8)

= 384 cubic ft.

PART - B:

I recommend Joe to make the tent -1 with base 10x10 ft. as it has more volume

Step-by-step explanation:

Side 1= x

Side 2= x+20

Side 3= x+40

Side 4= x+60

Side 5= x+80

Total perimeter= 401

x+x+20+x+40+x+60+x+80= 401

Simplify it...

5x=201

x= 40.2

This is the answer= 40.2

Please award me brainliest!

<u>Full question:</u>

A student wants to find the answer to the question “What is the most popular restaurant in Bedford?” He asks 20 randomly selected customers at one local restaurant. Which best describes the accuracy of the results of the survey?

The survey results will be accurate since the sample was chosen randomly.

The survey results will be inaccurate since the entire population should have been surveyed.

The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant.

The survey results will be accurate since the sample represents the population and the population is the target of the survey.

<u>Option C</u>

The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant best describes the accuracy of the results of the survey

<h3><u>Explanation:</u></h3>

In a statistical study, sampling methods relate to how we choose members from the population to be in the research. If a sample isn't randomly chosen, it will reasonably be biased in some way and the data may not be representational of the population.

Efficient interpretation of data is based on real procedures for generating data and sensitive analysis of the data.The efficiency depends on how strongly the sample outlines the population. The sample must contain the attributes of the population to be representative. Here sample is chosen from one local restaurant so it willnot produce efficient analysis result.
