If they charges a one-time fee of $45, plus $25 per hour, then the the slope of this situation is $25 per hour.

The situation described can be represented by the linear equation

Cost = $45 + $25 × hours

where "Cost" is the total cost of the tour and "hours" is the number of hours for which the tour is taken.

The slope of this equation represents the rate of change in the cost of the tour with respect to the number of hours.

In other words, it tells us how much the cost increases for each additional hour of the tour.

The slope of this equation is simply the coefficient of the "hours" variable, which is $25.

Therefore, the slope of this situation is $25 per hour.

Answer:

$25 per hour.

Step-by-step explanation:

The measures of angles C and D are 70° and 100°, respectively.

Understanding angles is a fundamental concept in geometry. A quadrilateral is a polygon with four sides, and its angles are essential to determining its properties.

Let's start by labeling the angles in the quadrilateral. We know that two angles measure 100° and 90°, so let's label them as A and B, respectively. The other two angles, which we are trying to find, can be labeled as C and D.

Now, we are given that the ratio of angles C and D is 7:10. This means that we can write the following equation:

C/D = 7/10

We can use this equation to solve for one of the angles. Let's choose angle C. We can rewrite the equation as:

C = (7/10)D

We also know that the sum of the angles in a quadrilateral is 360°. Therefore, we can write another equation:

A + B + C + D = 360°

We can substitute the values we know into this equation and solve for angle D:

100° + 90° + (7/10)D + D = 360°

Simplifying the equation:

(17/10)D = 170°

D = 100°

Now that we know the value of angle D, we can use the equation we derived earlier to find the value of angle C:

C = (7/10)D = (7/10) x 100° = 70°

Step-by-step explanation:

The max value is where the far right point of the "whisker" is.

Answer:

the area of the isosceles triangle is approximately 104.49 cm^2.

Step-by-step explanation:

The perimeter of the triangle is 100 cm, so we can write an equation using the lengths of the sides:

x + x + (x + 10) = 100

3x + 10 = 100

3x = 90

x = 30

So the equal sides of the triangle have length 30 cm and the side that is 10 cm greater has length 40 cm.

To find the area of the triangle, we can use the formula for the area of an equilateral triangle:

Area = (sqrt(3) / 4) * (side length)^2

Area = (sqrt(3) / 4) * 30^2

Area = (sqrt(3) / 4) * 900

Area = (sqrt(3) / 4) * 30 * 30

Area = (sqrt(3) / 4) * 900

Area = (30 * sqrt(3)) / 2

Area = 45 sqrt(3)

Answer:

The value of z is 58    

Step-by-step explanation:

The mean is the average of a set of numbers.  Mean = (sum of the numbers)/(the number of numbers).

We are told that the mean of x+y+z is = 55.  

We can wriote this as:

 55 = (x+y+z)/3

We learn that x+y = 107.  So lets enter that number for x + y:

 55 = (x+y+z)/3

55 = ((x+y)+z)/3    

55 = ((107)+z)/3           [Substitution]

55 = (107+z)/3

165 = 107+z               [Multiply both sides by 3]

z = 58                       [Simplify]

CHECK:

Is the mean of x, y, and z 55?

55 = (x+y+z)/3  ?

55 = ((107)+z)/3 ?   [Since we know x+y = 107]

55 = ((107)+58)/3 ?  [Since z=58]

55 = (165)/3)  ?

55 = 55  YES  The value of z is 58    

The percentage increase is given by the equation A = t + 0.24t = 1.24t

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the percentage increase be represented as A

Now , the equation will be

The initial quantity be represented as t

Now , the increased quantity be represented as p = 24 %

So , the increased quantity = 24 % x initial quantity

Substituting the values in the equation , we get

The increased quantity = ( 24/100)t

The increased quantity = 0.24t

So , the final quantity = initial quantity + increased quantity

On simplifying the equation , we get

The final quantity = t + 0.24t

The final quantity = 1.24t

The probability of selecting a black card first and a red card second from a standard deck of 52 playing cards without replacement is 13/51.

The probability of selecting a black card on the first draw is 26/52, or 1/2, since there are 26 black cards in a standard deck of 52 playing cards.

After the first card is drawn, there are 51 cards remaining, of which 26 are red. Therefore, the probability of selecting a red card on the second draw, given that a black card was selected on the first draw, is 26/51.

To find the probability of both events happening (selecting a black card followed by a red card), we multiply the probabilities of each event:

P(black card first, red card second) = P(black card first) × P(red card second | black card first)

P(black card first, red card second) = (1/2) × (26/51)

P(black card first, red card second) = 13/51

I will assume the goal is not to waste any wood.  We need to find a common length that will allow each piece of wood to be divided into whole pieces with nothing left over.  The shortest plank is 70 m, but that length will cause a loss of 35 m on the 105m plank, and also 35m on the 175m plank after two 70m sections have been cut off (175 - 140 = 35).

Looking at the actual lengths, one might spot that they are all evenly divisible by 35.  See the table below.  The numbers under "35" are the result of the length divided by 35.  They are all whole numbers.  We can cut each plank into 35m sections and have none left over.

The radius line intersects the circle at (4, 8) because the tangent line's slope, which is -1/3, is perpendicular to the radius line's slope of (0, 8), which is 0.

1. Use m = 0 to calculate the slope of the line through point (12, 0).

2. Calculate the radical line's angle between the origin and the tangent point: m = ∞

3. To determine the location where the line touches the circle, use the relationship between the slopes: M2 = -1/M1 = -1/0 = - since M1 M2 = -1

4. To determine a point's coordinates, use the equation for a circle: (x - 8)2 + (y - 8)2 = 82, so (4, 8) (4, 8)

We can use the relationship between the slopes of the tangent line and the radical line from the origin to the tangent point to determine the location where the line contacts the circle. Since the tangent line crosses through point (12,0), its slope is equal to zero. Since the radical line slopes at m2 =, m1 m2 = -1. Accordingly, m2 = -1/m1 = -1/0 = -∞.The coordinates of the spot where the line touches the circle can then be determined using the equation for a circle. (x - 8)2 + (y - 8)2 = 82 is the equation for a circle having the origin as its center and a radius of 8.

A vertex is a point on a polygon where two rays or line segments meet, and the sides or edges of the object come together. Vertex is the plural form of vertices.

A straight line that can be extended endlessly is known as a ray. An angle is created when two line segments or rays cross one another. A vertex is created by definition whenever two lines come together to produce an angle.

Thus, we can state that a vertex is formed when two line segments or rays intersect.

Both the quantity of candy bars and bags of chips sold are Melanie sold five bags of chips and eighteen candy bars (5 + 13).

A product that has been sold has been exchanged for cash. You'll notice a "Sold" sign appear in the front yard of the house across the street whenever new neighbours purchase it.

In addition to being a noun, the verb sell has three different tenses: simple present, simple past, and past participle. I'll sell my current vehicle and purchase a new one. She is distributing water bottles at the football game. My old college textbooks were all sold on the internet yesterday.

Let x be the number of bags of chips sold, then the number of candy bars sold would be x + 13.

The total revenue from the sales of the bags of chips would be $1.25 * x and the total revenue from the sales of the candy bars would be $1.50 * (x + 13).

Since the total revenue was $33.25, we can set up an equation:

$1.25x + $1.50(x + 13) = $33.25

Expanding and simplifying the right side:

$1.25x + $1.50x + $19.50 = $33.25

Combining like terms:

$2.75x + $19.50 = $33.25

Subtracting $19.50 from both sides:

$2.75x = $33.25 - $19.50 = $13.75

Dividing both sides by $2.75:

x = $13.75 / $2.75 = 5
