Answer:

75%

Step-by-step explanation:

If you have a calculator, you can divide 39/52. If not,

39/52 = x/100

52x = 3900

x = 75

75/100 = 75%

The function P(x) representing Ayden's total pay on a day on which  he sell x dollar worth of computers is P(x) = 0.01x + 90

The base pay amount of Ayden per regardless of sales = $90

The commission of Ayden = 1% of the dollar amount of sales

Consider the total sales amount in a day as x

The function is the mathematical expression that shows the relationship between one variable and another variable. If one variable is dependent variable then the other variable will be independent variable.

Then the function will be

P(x) = 1% of x + 90

= 0.01x + 90

Therefore, the equation for the function P(x) = 0.01x + 90

The probability of picking three black cards in a row, without replacement, from a standard deck of 52 playing cards is 2/17, or approximately 0.1176 (rounded to four decimal places).

The probability of picking a black card on the first draw = 26/52 = 1/2

        (since there are 26 black cards in the deck)

The probability of picking a black card on the second draw, given that a one was picked on the first draw and the card is not replaced = 25/51,    

        (since there are now only 25 black cards left out)

The probability of picking a black card on the third draw, given that the ones picked on the first two draws are not replaced = 24/50 = 12/25,

        (since there are now only 24 black cards left out)

To pick three black cards in a row, we need to multiply the probabilities of each individual draw = (1/2) * (25/51) * (12/25) = 6/51

Answer:

(i) The volume of each hemispherical bowl can be calculated as follows:

Volume of a hemispherical bowl = (2/3) x pi x (d/2)^3, where d is the internal diameter of the bowl.

Substituting d = 21 cm, we get:

Volume of a hemispherical bowl = (2/3) x pi x (21/2)^3 = 4851.97 cubic centimeters

The total volume of compost required to fill all 16 bowls is therefore:

Total volume of compost = 16 x 4851.97 = 77631.52 cubic centimeters

If 1 cm³ of compost weighs 2.31 gm, then the total weight of required compost is:

Total weight of compost = 77631.52 x 2.31 = 179231.83 grams or 179.23 kilograms

Therefore, Mrs. Thapa would need 179.23 kilograms of compost to fill all 16 hemispherical bowls.

(ii) The outer curved surface area of each hemispherical bowl can be calculated as follows:

Outer curved surface area of a hemispherical bowl = 2 x pi x (d/2)^2, where d is the internal diameter of the bowl.

Substituting d = 21 cm, we get:

Outer curved surface area of a hemispherical bowl = 2 x pi x (21/2)^2 = 693.84 square centimeters

The total outer curved surface area of all 16 bowls is therefore:

Total outer curved surface area = 16 x 693.84 = 11101.44 square centimeters

If Mrs. Thapa covers the outer curved surface of each bowl with polythene sheet, then the total amount of polythene required would be equal to the total outer curved surface area of all 16 bowls.

Therefore, the total amount of polythene required would be 11101.44 square centimeters.

To accurately represent men's and women's shoe sizes separately, it is recommended to calculate and compare the average or median shoe size for each group separately.

The problem with the central measure, mean or median, in this case is that the data is not gender-specific and there is a possibility that male and female shoe size distributions are different. Therefore, calculating the average or median shoe size for all students may not accurately reflect the typical male and female shoe sizes, respectively.

For example, if the males in the sample have, on average, a larger shoe size than the females, then the average shoe size of all students might be biased towards the larger size, even if most of the students are female. On the other hand, if you have several boys with very large shoe sizes, the median shoe size of all students may be biased toward the larger size, even if most of the students are women with small shoe sizes.

To accurately represent men's and women's shoe sizes separately, it is recommended to calculate and compare the average or median shoe size for each group separately. Alternatively, a fashion report representing the most common shoe sizes in the data might be a better measure of the centroid.

Let's start with eliminating choices first ~

The value decreases as years pass by, so the value multiplied by initial value should be an exponent on the value that is less than 1.

So, only the choices with exponent on 0.9 should be qualified, eliminating the choices A and C

Next, the initial value of motorcycle is 12000 according to table. so at x = 0, v(x) should be equal to 12000.

Now, let's check option B

[tex]\qquad \sf  \dashrightarrow \: v(x) = 12000(0.9) {}^{x} [/tex]

[tex]\qquad \sf  \dashrightarrow \: v(0) = 12000(0.9) {}^{0} [/tex]

[tex]\qquad \sf  \dashrightarrow \: v(0) = 12000(1)[/tex]

[tex]\qquad \sf  \dashrightarrow \: v(0) = 12000[/tex]

And since choice B satisfy each and every condition, that's the correct answer ~

If an AP has first term 7 and common difference 4. If the sum of all it's terms is 900, then there are 3 terms.

Let's use the formula for the sum of an arithmetic progression to solve this problem:

S = n/2[2a + (n-1)d]

where S is the sum of the first n terms, a is the first term, d is the common difference, and n is the number of terms.

We know that a = 7 and d = 4, and we're given that S = 900. Substituting these values into the formula, we get:

900 = n/2[2(7) + (n-1)(4)]

Simplifying the expression inside the brackets:

900 = n/2[14 + 4n - 4]

900 = n/2[10 + 4n]

Multiplying both sides by 2 to eliminate the fraction:

1800 = n[10 + 4n]

Simplifying the right-hand side:

1800 = 4n^2 + 10n

Rearranging to get a quadratic equation in standard form:

4n^2 + 10n - 1800 = 0

We can solve for n using the quadratic formula:

n = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 4, b = 10, and c = -1800, so:

n = (-10 ± √(10^2 - 4(4)(-1800))) / 2(4)

n = (-10 ± √(100 + 28800)) / 8

n = (-10 ± √(28900)) / 8

n = (-10 ± 170) / 8

n = 20/8 or n = -180/8

n = 2.5 or n = -22.5

Since the number of terms must be a positive integer, we can discard the negative solution and conclude that there are 2.5 terms. However, this doesn't make sense because the number of terms in an arithmetic progression must be a whole number. Therefore, we need to round up to the nearest whole number, which gives us:

n = 3

Therefore, there are 3 terms in the arithmetic progression with first term 7 and common difference 4, and the sum of these terms is 900.

Answer: Dear Editor,

I am writing to bring to your attention the serious issue of rising air and noise pollution in our area. The daily air quality index that appears in the newspaper highlights the extent of the problem, and I believe it is important for the public to be aware of its effects.

Air pollution has been linked to a number of health problems, including respiratory issues, heart disease, and even cancer. The presence of harmful pollutants in the air we breathe is cause for concern and demands immediate attention. Similarly, noise pollution can lead to hearing loss, sleep disturbance, and increased stress levels.

It is imperative that we take action to curb the effects of air and noise pollution. There are several measures that can be taken, both by individuals and by the government. On an individual level, we can reduce our carbon footprint by using public transportation, carpooling, or biking instead of driving alone. We can also plant trees and install air purifiers in our homes.

The government, on the other hand, can take steps to regulate industrial emissions, enforce stricter penalties for violators, and promote the use of clean energy sources. Additionally, they can create green spaces and establish noise-free zones in residential areas.

In conclusion, the rise in air and noise pollution is a pressing issue that affects the health and well-being of everyone in our community. I urge the public to take this matter seriously and support efforts to reduce its impact. Together, we can work towards a cleaner and healthier future.

Step-by-step explanation:

The slope-intercept form of a line is y=2/3x + 2, the line is perpendicular and shifted down 8 is y = -3/2x - 6.

The slope-intercept form of a line is y = mx + b, where m is the slope of the line and b is the y-intercept. In the given equation, y = 2/3x + 2, the slope is 2/3 and the y-intercept is 2.

To find a line that is perpendicular to this line, we need to find a line that has a slope that is the negative reciprocal of the slope of the given line. The negative reciprocal of 2/3 is -3/2, so the slope of the new line will be -3/2.

Now we need to find the equation of the new line in slope-intercept form. We know the slope of the line (-3/2), so we can substitute this value for m in the slope-intercept form and get:

y = -3/2x + b

To find the value of b, which is the y-intercept of the new line, we need to use the fact that the line is shifted down 8 units. We can do this by subtracting 8 from the y-intercept of the given line (which is 2), to get:

b = 2 - 8 = -6

So the equation of the line that is perpendicular to y = 2/3x + 2 and shifted down 8 units is:

y = -3/2x - 6

This line has a slope of -3/2, which is the negative reciprocal of the slope of the given line, and a y-intercept of -6, which is 8 units lower than the y-intercept of the given line.

The transformed function is y = -f(x + 3) - 2, obtained by reflecting the quadratic function over the x-axis, shifting it left by 3 units, and down by 2 units.

To reflect a quadratic function over the x-axis, we need to multiply the function by -1. Let's assume that our original quadratic function is f(x).

After reflecting the function over the x-axis, we get the new function g(x) = -f(x).

To perform a horizontal shift left 3 units, we need to replace x with (x + 3) in the function g(x). This gives us the new function h(x) = g(x + 3) = -f(x + 3).

Finally, to shift the function down 2 units, we need to subtract 2 from the entire function h(x).

Note that the order of the transformations is important. We first reflect the function over the x-axis, then shift it horizontally, and finally shift it vertically.

Hence,

Answer: Let's call Sarah's original amount of money as x. Then, Christine had 0.8x.

After they spent $684 altogether, Christine had 0.8x - 0.25(0.8x) = 0.8x - 0.2x = 0.6x left.

Sarah had x - 684.

Since Christine had thrice as much money left as Sarah, we can write an equation:

0.6x = 3(x - 684)

Expanding the right side of the equation:

0.6x = 3x - 2052

Solving for x:

2.6x = 2052

x = 787.69

So Sarah originally had 787.69 dollars and spent 787.69 - 684 = 103.69 dollars.

There are approximately 160 acres in a lot that is 1/2 mile by 1/2 mile.

To find the number of acres in a lot, you can use the following formula:

Number of acres = (length in feet) x (width in feet) / 43,560

First, convert the length and width from miles to feet. There are 5,280 feet in a mile, so:

Length in feet = 1/2 mile x 5,280 feet/mile = 2,640 feet
Width in feet = 1/2 mile x 5,280 feet/mile = 2,640 feet

Next, plug these values into the formula:

Number of acres = (2,640 feet) x (2,640 feet) / 43,560 = 174,240,000 / 43,560 = 160 acres

Therefore, there are approximately 160 acres in a lot that is 1/2 mile by 1/2 mile.

What is Perimeter?

Perimeter is the total length of the boundary of a two-dimensional shape or figure. It is the distance around the outside of a closed shape, such as a rectangle, triangle, circle, or any other polygon. To find the perimeter of a shape, you add up the lengths of all its sides. Perimeter is usually measured in units of length, such as centimeters, meters, feet, or inches. Perimeter is an important concept in geometry, and it is used to calculate the amount of material needed to surround a shape or to measure the distance around a path or track.

Let's denote the lengths of the three remaining sides of the kite as x, y, and z, where x is the shortest side.

The perimeter of the kite is the sum of the lengths of all four sides:

P = x + y + z + 18

We also know that the total length of plastic used to frame the perimeter is 94 inches:

94 = 2x + 2y + 2z + 36

Simplifying the equations by dividing both sides of the second equation by 2, we get:

47 = x + y + z + 18

47 = x + y + z + 18

Substituting the first equation into the second equation, we get:

x + y + z + 18 = 2x + 2y + 2z + 36

Simplifying this equation, we get:

x = 8

Substituting x = 8 into the first equation, we get:

y + z + 26 = 47

Simplifying this equation, we get:

y + z = 21

We want to find the values of y and z. Since we don't have enough information to solve for each of them individually, we'll use a bit of logic to determine their relative values.
