Answer:

The surface area of the ten t including the floor is 52.8 m².

Step-by-step explanation:

We are given that,

Shaun's tent consists of 3 rectangles and 2 triangles.

1. The dimensions of the rectangles are 5 × 3 meters.

<h3>Since, Area of the rectangle = Length × Width </h3>

i.e. Area of 3 rectangles = 3 × Length × Width

i.e. Area of 3 rectangles = 3 × 5 × 3 = 45 m²

<em>Thus, area of the 3 rectangles is 45 m².</em>

2. The dimensions of the triangles are base= 3 meter and height= 2.6 meter

<h3>As, Area of the triangle = \frac{1}{2}\times Base\times Height</h3>

i.e. Area of 2 triangles = 2\times \frac{1}{2}\times Base\times Height

i.e. Area of 2 triangles = Base\times Height

i.e. Area of 2 triangles = 3\times 2.6

i.e. Area of 2 triangles = 7.8 m²

Thus, area of 2 triangles is 7.8 m².

<em>So, the total surface area of the prism = Area of rectangles + Area of triangles</em>

i.e. Total surface area = 45 + 7.8 = 52.8 m²

Hence, the surface area of the ten t including the floor is 52.8 m².

Answer:

According to the diagram,  is the polar angle (the "vertical" angle made with the positive z-axis) and  is the azimuthal angle (the "horizontal" angle made with the positive x-axis), so the convention used here is to take

This table shows the number of miles that Sharon rode her bicycle in six weeks. If the mean number of miles she rode is 30, find
Nastasia [14]
(21 + 34 + x + 25 + 37 + 22) / 6 = 30
(139 + x) / 6 = 30 .....multiply both sides by 6
139 + x = 30 * 6
139 + x = 180
x = 180 - 139
x = 41......so during week 3, she rode her bike 41 miles

An apple farmer is deciding how to use each day's harvest. She can use the harvest to produce apple cider or apple juice for the
Andreas93 [3]

Answer:For this item, we let x and y be the number of bushels of apple that will be used to produce apple cider and apple juice, respectively. The situation above is best represented by the following equations,

                                           x + y = 18

                                          20x + 15y = 330

The values of x and y from the equations above are 12 and 6, respectively. Therefore, 12 bushels will be used to make apple cider and 6 bushels will be used to make apple juice.

PtichkaEL [24]
Margin of error, e = Z*SD/Sqrt (N), where N = Sample population

Assuming a 95% confidence interval and substituting all the values;
At 95% confidence, Z = 1.96

Therefore,
0.23 = 1.96*1.9/Sqrt (N)

Sqrt (N) = 1.96*1.9/0.23

N = (1.96*1.9/0.23)^2 = 262.16 ≈ 263

Minimum sample size required is 263 students.
