Answer:

5 people

Step-by-step explanation:

Let

The total cost was $1400, which was to be divided equally among the members going. Then,

y = 1400 / x [1]

Prior to the trip, 3 members decided not to go. The cost per person increased by $105.

y + 105 = 1400 / (x - 3)

(y + 105) . (x - 3) = 1400 [2]

We replace [1] in [2],

(1400/x + 105) . (x - 3) = 1400

1400 - 4200/x + 105x -315 = 1400

- 4200/x + 105x = 315

(- 4200 + 105x²)/x = 315

- 4200 + 105x² = 315 x

105x² - 315x - 4200 = 0

When we solve this quadratic equation using the quadratic formula, we get x₁ = 8 and x₂ = -5. Only the positive x has sense.

The people that went to the expedition was x - 3 = 8 - 3 = 5.

The rate of change of y with respect to x is 35 words per minute.

The rate of change of y with respect to x can be found by taking the slope of the line that represents the relationship between x and y. To find the slope, we can use the formula:

slope = change in y / change in x

Using the given information, we can calculate the slope as:

slope = (525 - 140) / (15 - 4) = 385 / 11 = 35

Therefore, the rate of change of y with respect to x is 35 words per minute.

Final answer:

Jeremy's rate of change in typing speed is 35 words per minute, calculated by dividing the change in words typed by the change in time (385 words/11 minutes).

Explanation:

The student is asking about the rate of change of the words typed with respect to time spent typing. To calculate this, we will use the given values: 140 words in 4 minutes and 525 words in 15 minutes. The rate of change, essentially being the slope of the line that represents the relationship between words typed (y) and the time (x), can be calculated by finding the ratio of the change in words to the change in time:

This means that Jeremy types at an average speed of 35 words per minute.

The length of the rectangle with a perimeter of 36 meters and a length that is 2 meters more than three times the width is 14 meters.

The perimeter of a rectangle is twice the sum of its length and width. According to the question, the perimeter of the rectangle is 36 meters, and the length (L) is 2 meters more than three times the width (W). We can express this relationship as follows: L = 3W + 2.

The formula for the perimeter (P) of a rectangle is P = 2L + 2W.

Using the given perimeter of 36 meters, we can set up the equation as 2(3W + 2) + 2W = 36.

Simplifying this equation, we find that 8W + 4 = 36, and thus W = 4 meters.

Substituting the value of W back into the equation for L gives us L = 3(4) + 2, which means the length of the rectangle is 14 meters.

The point that is closest to the point (3, 0) can be found by finding the

minimum value for the function of the distance between points.

The closest point on the hyperbola  x·y = 8 to the point (3, 0) is the point [tex]\underline{(4, \ 2)}[/tex]

Reasons:

The equation of the hyperbola is x·y = 8

The given point = (3, 0)

Therefore;

[tex]y = \dfrac{8}{x}[/tex]

The distance of a point from a line, [tex]d = \mathbf{ \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}}[/tex]

Where;

(x₁, y₁) = (3, 0)

(x₂, y₂) = The closest point on the hyperbola

We get;

[tex]d = \sqrt{\left (y-0 \right )^{2}+\left (x-3 \right )^{2}}[/tex]

Which gives;

[tex]d = \sqrt{\left (\dfrac{8}{x} -0 \right )^{2}+\left (x-3 \right )^{2}} = \mathbf{ \sqrt{\left (\dfrac{8}{x}\right )^{2}+\left (x-3 \right )^{2}}}[/tex]

At the minimum distance, using an online app, we have;

[tex]\dfrac{d}{dx}d = \dfrac{d}{dx} \left( \sqrt{\left (\dfrac{8}{x}\right )^{2}+\left (x-3 \right )^{2}} \right) = \dfrac{-64 + x^3 \cdot (x - 3)}{x^2 \cdot \sqrt{x^2 \cdot (x - 3)^2 + 64} } = 0[/tex]

Which gives;

x³·(x - 3) - 64 = 0

Using a graphing calculator, we get;

(x - 4)·(x³ + x² + 4·x + 16) = 0

Therefore;

A solution for the closest or point of minimum distance is x = 4

Which gives;

[tex]y = \dfrac{8}{4} = 2[/tex]

Therefore, the closest point on the hyperbola  x·y = 8 to the point (3, 0) is the

To find the different options for a car model with multiple customizable features, you multiply the number of choices for each feature. For this model, with 10 colors, 2 options each for transmission, four-wheel drive, and air conditioning, and 3 speaker options, there are 240 different combinations.

To calculate the number of different options for this model of a car, we need to consider all the features that can be selected and multiply the number of choices for each feature together. For the color, there are 10 options. For each of the features, such as automatic transmission, four-wheel drive, and air conditioning, there are 2 choices: with or without. Finally, for the radio-CD speakers, there are 3 options: two, three, or four speakers. Multiplying these choices together gives us the total number of different options:

10 (colors) × 2 (transmission) × 2 (four-wheel drive) × 2 (air conditioning) × 3 (radio-CD speakers) = 240 different options.

So, there are 240 different options available for this model of a car.

Final answer:

To find the total number of different options for the car, we multiply the number of choices for each feature resulting in 240 different options.

Final answer:

The ratio of red cards to other cards that Brent counted (10 red cards, 10 black cards, 20 blue cards) is 1:3 after summing black and blue cards to find the total number of other cards and simplifying the ratio.

Explanation:

Brent counted 10 red cards, 10 black cards and 20 blue cards. The question is what is the ratio of red cards to other cards. To calculate the ratio, we need to determine the total number of cards that are not red, which would be the black and blue cards combined.

First, we sum the black and blue cards:

10 black cards + 20 blue cards = 30 other cards.

Now, we set up the ratio of red cards to other cards:

10 red cards : 30 other cards, which simplifies to 1 : 3 when both sides of the ratio are divided by 10, the greatest common divisor.

Therefore, the ratio of red cards to other cards is 1:3.

Final answer:

Ava can capture the chip on square 72 by using the +30 change card once to reach 66, and then the +1 change card six times to reach the final value of 72.

Explanation:

Ava's game piece is on square number 36, and she wants to capture a chip on square number 72. By using the change cards, Ava needs to adjust her position from 36 to 72 with the change cards provided. The change cards are: -10, +30, -1, +1, and -2. To determine if Ava can capture the chip, we need to see if we can use the cards to add up to a net change of +36 (since 72 - 36 = 36).

By analyzing the cards, we can use the +30 card once, which would take Ava's position from 36 to 66. Next, she can use the +1 card six times to go from 66 to 72. Ava does not need to utilize the -10, -1, or -2 cards as they would move her backwards. Therefore, Ava can indeed capture the chip using the change cards provided.

The steps Ava should follow are:

Use the +1 card six times to move from 66 to 72.

The calories in a 21-oz iced tea that is originally 78 calories in a 13-oz serving, multiply the calories per ounce by the new serving size for a total of 126 calories.

The 13-oz iced tea contains 78 calories. To find the calories in a 21-oz iced tea:

Calculate the calories per ounce: 78 calories ÷ 13 oz = 6 calories/oz

Multiply the calories per ounce by the 21-oz serving size: 6 calories/oz × 21 oz = 126 calories in a 21-oz iced tea

To find the length of the ladder, we can use the property of right triangles. The length of the ladder is 10 feet.

To find the length of the ladder, we can use the property of right triangles. Let's assume the length of the ladder is 'L'.

According to the given information, the distance from the ground to the top of the ladder is 2 feet less than the length of the ladder. So, the height of the triangle formed by the ladder, the building, and the ground is L - 2.

The distance from the bottom of the ladder to the building is given as 6 feet. Using the Pythagorean theorem, we can set up the following equation: (L-2)^2 + 6^2 = L^2

Simplifying the equation, we get L^2 - 4L + 4 + 36 = L^2, which simplifies further to 40 = 4L. Dividing both sides by 4, we get L = 10.

Therefore, the length of the ladder is 10 feet.
