The surface area of each square pyramid, we used the formula Surface Area = Base Area + 4 x (1/2 x Base x Height of Face) is 1049.2mm², 1285.8mm² and 2100mm². The cost to cover each pyramid was $1.05, $1.29 and $2.10.

To calculate the surface area of each pyramid, we need to use the formula

Surface Area = Base x Height of face + 2 x ((Base/2) x Slant Height)

For the small pyramid, we have

Surface Area = 20 x 25 + 2 x ((20/2) x 26.46)

Surface Area = 500 + 2 x 10 x 26.46

Surface Area = 1049.2 mm²

Cost to cover the small pyramid

Cost = Surface Area x 0.001

Cost = 1049.2 x 0.001

Cost = $1.05

For the medium pyramid, we have

Surface Area = 20 x 40 + 2 x ((20/2) x 42.43)

Surface Area = 800 + 2 x 10 x 42.43

Surface Area = 1285.8 mm²

Cost to cover the medium pyramid

Cost = Surface Area x 0.001

Cost = 1285.8 x 0.001

Cost = $1.29

For the large pyramid, we have

Surface Area = 30 x 40 + 2 x ((30/2) x 50)

Surface Area = 1200 + 2 x 15 x 50

Surface Area = 2100 mm²

Cost to cover the large pyramid

Cost = Surface Area x 0.001

Cost = 2100 x 0.001

Let's call the cost of each video game "x". We can set up two equations based on the information given:

4x + 2(0.01) = 20.92 (the 0.01 represents the commission fee for each phone)

4x = 20.92 - 0.02

4x = 20.90

x = 5.225

So each video game costs $5.225.

We can double-check our answer using the information about the friend's sales:

4(5.225) + 3(0.01) = 23.44

20.90 + 0.03 = 23.44

23.44 = 23.44

So our answer is correct.

Answer:

To calculate the average annual percentage gain, we need to use the formula:

Average annual percentage gain = ((Ending value / Beginning value)^(1/n) - 1) x 100%

where:

- Ending value = the value of the investment at the end of the period

- Beginning value = the value of the investment at the beginning of the period

- n = the number of years

In this case, the beginning value of the stocks is not given, so we cannot calculate the exact average annual percentage gain. We only know the profit and the ending value. However, we can make an estimate assuming that the profit is equal to the gain, i.e., there were no transaction costs or other fees.

If the profit was $3,250 and the ending value was $10,500, then the beginning value was:

Beginning value = Ending value - Profit

Beginning value = $10,500 - $3,250

Beginning value = $7,250

The number of years is given as 4.

Using the formula above, we can estimate the average annual percentage gain as:

((10,500 / 7,250)^(1/4) - 1) x 100%

= (1.1267^(0.25) - 1) x 100%

= (1.0266 - 1) x 100%

= 0.0266 x 100%

= 2.66%

Therefore, the estimated average annual percentage gain is 2.66%.

Step-by-step explanation:The six sample minimums are 15, 15, 15, 18, 18, and 20.

To find the mean of all six sample minimums, we add them up and divide by 6:

(15 + 15 + 15 + 18 + 18 + 20) / 6 = 16.1667

So the mean of all six sample minimums is $16,166.67.

The population minimum is the smallest cost among the four cars, which is $15,000.

The sample minimum is a biased estimator of the population minimum. Since the samples are of size 2, the probability of obtaining the population minimum as the sample minimum is only 1/3 (when the minimum of the two cars selected is the population minimum). Therefore, the sample minimum tends to underestimate the population minimum.

x² + 5x + 3 = 0, the quadratic equation has two distinct real roots

2x² - 2x + 1 = 0, no real roots. Instead, it has two complex conjugate roots.

x² + 5x + 3 = 0

To determine the nature of the roots of this quadratic equation, we need to calculate the discriminant using the formula:

Discriminant = b² - 4ac

where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.

In this case, a = 1, b = 5, and c = 3.

Discriminant = (5)² - 4(1)(3)

= 25 - 12

= 13

Since the discriminant is positive and not a perfect square, the quadratic equation has two distinct real roots

Now 2x² - 2x + 1 = 0

a = 2, b = -2, and c = 1

Plugging these values into the discriminant formula, we get:

b²  - 4ac = (-2)²  - 4(2)(1) = 4 - 8 = -4

Since the discriminant is negative, the quadratic equation 2x² -2x+1=0 has no real roots.

Instead, it has two complex conjugate roots.

The two inequalities that the graph represents are:

y < -x + 4

y ≤ ²/₃x - 4

An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.

The formula for the equation of a line in slope intercept form is:

y = mx + c

where:

m is slope

c is y-intercept

The first inequality is the one with the dashed line and a y-intercept of 4 and so since shaded below line, we will use the symbol <.

The slope from two coordinates on the line (0, 4) and (4, 0) is:

(0 - 4)/(4 - 0) = -1

Thus, inequality is:

y < -x + 4

The first inequality is the one with the solid line and a y-intercept of -4 and so since shaded below line, we will use the symbol ≤.

The slope from two coordinates on the line (0, -4) and (6, 0) is:

(0 + 4)/(6 - 0) = 2/3

Since John cannot buy a fraction of a can, he needs to round up to the nearest whole number. So, John needs at least 5 cans of paint to cover the entire wall as per the height and length.

To calculate the area of the wall, we need to multiply the height and the length of the wall.

From the diagram, we can see that the height of the wall is 2 meters and the length is 5 meters.

So the total area of the wall is:

Area = height x length

Area = 2 meters x 5 meters

Area = 10 square meters

To convert this to square feet, we can use the conversion factor:

1 square meter = 10.764 square feet

So:

Area = 10 square meters x 10.764 square feet/square meter

Area = 107.64 square feet

Since 1 can of paint covers 24 square feet, John needs:

Number of cans = Area ÷ Coverage per can

Number of cans = 107.64 square feet ÷ 24 square feet/can

Number of cans = 4.485 cans

Thus, John needs at least 5 cans of paint to cover the entire wall.

The real exchange rate is 0.75.

It is not possible to make a profit by buying apples in one country and selling them in another.

We have,

To find the real exchange rate, we need to compare the price of apples in the two countries in terms of their respective currencies.

In the U.S., a bushel of apples costs $15.00.

In Japan, the same apples cost 1,600 yen.

Using the exchange rate of 80 yen per dollar, we can convert the cost in yen to dollars:

1,600 yen / 80 yen per dollar

= $20.00

So, the price of a bushel of apples in Japan is equivalent to $20.00 in the U.S.

The real exchange rate is the ratio of the prices of the same goods in two different countries, taking into account the exchange rate.

In this case, the real exchange rate is:

Real exchange rate = Price in U.S. / Price in Japan

= $15.00 / $20.00

= 0.75

This means that it takes 0.75 U.S. dollars to buy the same goods in Japan which would cost 1 Japanese yen.

To determine if there is an arbitrage opportunity, we need to compare the real exchange rate with the actual exchange rate.

If the real exchange rate is greater than the actual exchange rate, there is an arbitrage opportunity for someone to buy the good in one country and sell it in another country for a profit.

However, if the real exchange rate is less than the actual exchange rate, there is no arbitrage opportunity.

In this case,

The real exchange rate is 0.75, while the actual exchange rate is 80 yen per dollar, or 0.0125.

Since the real exchange rate is less than the actual exchange rate, there is no arbitrage opportunity.

Therefore,

The real exchange rate is 0.75.

Step-by-step explanation:We can solve this quadratic equation in sin(θ) by using the substitution u = sin(θ):

-6u^2 - 5u + 3 = 0

Now we can use the quadratic formula to solve for u:

u = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = -6, b = -5, and c = 3. Substituting these values, we get:

u = (5 ± sqrt(5^2 - 4(-6)(3))) / 2(-6)

u = (5 ± sqrt(109)) / (-12)

Therefore, either:

sin(θ) = (5 + sqrt(109)) / (-12)

Let the time spent at the first 3 exhibits = 3/4 + 3/4 + 3/4 = 9/4 hours

Let the time spent at the museum after the first 3 exhibits = 1 1/2 = 3/2 hours

Total time spent at the museum = 9/4 + 3/2 = (9/4 + 6/4) = 15/4 hours

Since the museum closes after you spend a total of 4 1/2 hours at the museum, we can subtract the total time spent at the museum from the closing time to find the time it took you to walk to the museum:

Closing time - Total time spent at the museum = 4 1/2 - 15/4

The area of the shaded region of a circle with a 100 degree angle and a radius of 3cm, using pi=3.14, is approximately 25.64 square centimeters.

To find the area of the shaded region of a circle, we need to subtract the area of the sector formed by the shaded region from the area of the whole circle.

The area of the whole circle is given by

A = πr²

where A is the area of the circle, r is the radius of the circle, and π is a mathematical constant approximately equal to 3.14 (as given in the question).

Substituting the given values, we get

A = π(3cm)²

A = 28.26 cm² (rounded to two decimal places)

Now, let's find the area of the sector formed by the shaded region.

The angle of the sector is given as 100 degrees. To find the area of the sector, we need to use the formula:

A = (θ/360)πr²

where θ is the angle in degrees, r is the radius of the circle, and π is again approximately equal to 3.14.

Substituting the given values, we get

A = (100/360)π(3cm)²

A = 2.62 cm² (rounded to two decimal places)

Finally, we can find the area of the shaded region by subtracting the area of the sector from the area of the whole circle

Shaded area = Area of circle - Area of sector

Shaded area = 28.26 cm² - 2.62 cm²

Shaded area = 25.64 cm² (rounded to two decimal places)
