find the area of each triangle using the formula of A=L×W/2​

The surface area of the composite figure is 2,283 m².

option A.

The surface area of the composite figure is calculated as follows;

The composite figure is composed of a cube and a cuboid and their total surface area is calculated as follows;

Surface area of the cuboid = 2 (35 m x 9 m  +  35 m x 16 m   +  16 m x 9 m)

Surface area of the cuboid = 2038 m²

Surface area of a cube = 6L²

There is a surface of the cube on the cuboid, which is include in the surface area of the cuboid, so we will subtract that one surface.

Surface area of the cube = 6L² - L² = 5L²

= 5 x (7 m)²

= 245 m²

Total surface area =  2038 m² + 245 m²

Total surface area = 2,283 m²

Step-by-step explanation:

The height of the pyramid is 12 units

To find the height of the pyramid, we need to use the formula for the volume of a pyramid,

V = (1/3) * B * h,

where V is the volume, B is the area of the base, and h is the height of the pyramid.

In this case, we know that the volume of the pyramid is 120 units cubed, and the base of the pyramid is a triangle with a base of 10 units and a height of 6 units.

Therefore, the area of the base is,

(1/2) * 10 * 6 = 30 square units.

Plugging these values into the formula for the volume of a pyramid, we get:

120 = (1/3) * 30 * h

Multiplying both sides by 3, we get:

360 = 30 * h

Dividing both sides by 30, we get:

h = 12

Therefore, the height of the pyramid is 12 units.

The probability of drawing 2 red marbles is 0.081 or 8.1%.

There are 15 red marbles and 32 blue marbles, so there are 15+32=47 marbles total.

The probability of pulling a red marble on the first draw is 15/47.

If the first marble drawn is red, then there are 14 red marbles and 32 blue marbles remaining.

So, the probability of pulling a second red marble is 14/46.

To find the probability of both events happening, we multiply the probabilities:

P(both red) = P(first red) × P(second red | first red)

P(both red) = (15/47) × (14/46)

P(both red) = 0.081 (rounded to 3 decimal places)

Therefore, the probability of drawing 2 red marbles is approximately 0.081 or 8.1%.

To find out how many hours they zip lined for, we need to subtract the cost of the gear and trainer from the total bill and then divide the remaining amount by the hourly rate.

Cost of gear per person:

Shoes: $10

Helmet: $3

Gloves: $2.50

Harness: $5.00

Total gear cost per person: $10 + $3 + $2.50 + $5.00 = $20.50

Total cost of gear for 3 people: $20.50 x 3 = $61.50

Cost of trainer: $15.00

Total bill (including gear and trainer): $70.25

Remaining amount for zip lining:

=  $70.25 - $61.50 - $15.00

= $-6.25

Since the remaining amount is negative, it seems there might be an error in the calculation or information provided. The total bill should not be lower than the cost of gear and trainer.

However, if we assume the total bill is correct and there was an error in the calculation, we can proceed with finding out how many hours they zip lined for and how much each person paid.

Approximate number of hours:

Number of hours = Remaining amount / Hourly rate = $6.25 / $4.75 ≈ 1.32 hours

The area and circumference of the circle with a radius of 8 inches are 200.96 square inches and 50.24 inches respectively.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The area of a circle is expressed mathematically as;

A = πr²

The circumference of a circle is expressed as:

C = 2πr

Where r is radius and π is constant pi ( π = 3.14 )

Given that the radius of the circle is 8 inches.

Substituting this value into the formula, we get:

A = πr²

A =  3.14 × ( 8 in )²

A =  3.14 × 64 in²

A = 200.96 in²

Next, we calculate the circumference:

C = 2πr

C = 2 × 3.14 × 8 in

C = 50.24 in

Therefore, the value of the circumference is 50.24 in.

The  recursive formula of g(n)  g(1) = -50 and g(n) = g(n-1) - 15

g(n) = g(n-1) - 15

Start with the given formula: G(n) = -50 - 15n

To find the recursive formula, we need to find the value of g(n) in terms of g(n-1).

To do this, we can subtract 15 from both sides of the equation:

G(n) - 15 = -50 - 15n - 15

Simplifying the equation, we get:

G(n) - 15 = -65 - 15n

Rearranging the equation, we get:

G(n) = -65 - 15n + 15

Now, we can substitute g(n-1) for -65 - 15n:

G(n) = g(n-1) - 15

Finally, we can find the value of g(1) by substituting n = 1 into the original equation:

G(1) = -50 - 15(1)

G(1) = -50 - 15

G(1) = -65

The 95% confidence interval for the difference in proportions is approximately 0.0957 to 0.4977.

To find the 95% confidence interval for the difference in proportions between Michigan and New York commuters who drove alone to work, we can use the formula:

CI = (p1 - p2) ± Z * sqrt((p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2))

Where:

p1 and p2 are the proportions of Michigan and New York commuters who drove alone to work, respectively.

n1 and n2 are the sample sizes of Michigan and New York commuters, respectively.

Z is the critical value corresponding to the desired confidence level (95% confidence level has Z ≈ 1.96).

Given:

Michigan: p1 = 78/100 = 0.78, n1 = 100

New York: p2 = 58/120 = 0.4833, n2 = 120

Plugging in the values:

CI = (0.78 - 0.4833) ± 1.96 * sqrt((0.78 * (1 - 0.78) / 100) + (0.4833 * (1 - 0.4833) / 120))

CI = 0.2967 ± 1.96 * sqrt(0.006456 + 0.004074)

CI = 0.2967 ± 1.96 * sqrt(0.01053)

Tshego's budget is more than R7200, then it would be enough to finish the tiling project. If his Budget is less than R7200, then it would not be enough.

We are not provided with any information in the question, so we cannot answer it as is. However, we can use the formula provided to calculate the total floor area to be tiled:

Area of a rectangle = length x width

Let's say the length is L and the width is W. Then, the total floor area to be tiled is:

Total floor area = L x W

We are not given the values of L and W, so we cannot calculate the exact total floor area. However, we can assume that Tshego has already calculated the total floor area to be 32 m².

To determine how many boxes of tiles Tshego will need, we need to know the size of each box of tiles and the total area that one box can cover. Let's assume that each box of tiles covers an area of 1 m².

If the total floor area to be tiled is 32 m², and an extra 10% of the number of tiles must be added for cutting and breakages, then the total area to be covered with tiles would be:

Total area to be covered = 32 m² x 1.1 = 35.2 m²

Therefore, Tshego would need 36 boxes of tiles to cover the entire floor area.

To determine if Tshego's budget is enough to finish the tiling project, we need to know the cost of each box of tiles and the total cost of the project. Let's assume that each box of tiles costs R200.

The total cost of the project would be:

Total cost = Number of boxes x Cost per box

Total cost = 36 x R200 = R7200

If Tshego's budget is more than R7200, then it would be enough to finish the tiling project. If his budget is less than R7200, then it would not be enough.

It is found that x = -1/3 is the point of inflection again for function f(x) = 3x⁴ + 2x³ - 5x - 12.

Since the second variation of the function f(x) = 3x⁴ + 2x³ - 5x - 12 and then solving for the values of x where the second derivative equals zero

f'(x) = 12x³ + 6x² - 5

f''(x) = 36x² + 12x

We should discover the solutions to the equation f"(x) = 0 for x to determine the locations of inflection:

36x² + 12x = 0

12x(3x + 1) = 0

If x = 0 or x = -1/3, the equation is true.

Here F"(x) > 0 demonstrates that the graph of f(x) is concave if x 1/3.

Concavity in the curve of f(x) at -1/3 x 0 shows that f"(x) 0.

When x is greater than zero, then f"(x) is greater than zero, showing that f(x graph) is concave up.
