A family wants to rent a car to go on vacation. Company A charges ​$35.50 and 9¢ per mile. Company B charges ​$55.50 and 13¢ per mile. How much more does Company B charge for x miles than Company A​?

Step-by-step explanation:

The general solution of the differential equation can be found as follows:

dQ/dx = k/x^2

Integrating both sides, we get:

Q = k * ln|x| + C

where C is the constant of integration.

Therefore, the distance covered by a passenger vehicle during one turn of the wheel is roughly 471.2 feet (rounded to the nearest tenth).

The ratio of a circle's circumference to width serves as the basis for the traditional meaning of Pi (). The diameter or extent of a circular is its circumference. A straight line connecting a spot on one point of the circular to a point at the other end, going through the middle, is the diameter.

The following algorithm determines a circle's circumference:

C = πd

where d is the diameter of the circle. In this case, the diameter of the Ferris wheel is 150 ft, so its circumference is:

C = π(150) ≈ 471.2 ft

This indicates that a full rotation of the Ferris wheel is equal to a passenger vehicle moving about 471.2 feet.

The cardinality of a set refers to the number of elements in the set. If the set X has cardinality 16 and the set Y has cardinality 24, then the number of elements in set X is 16 and the number of elements in set Y is 2.

If their intersection has cardinality 21, then the number of elements that both sets have in common is 21.To determine the number of elements contained in the union of X and Y, we need to subtract the number of elements in their intersection from the sum of the cardinalities of X and Y. That is,

|X U Y| = |X| + |Y| - |X ∩ Y| = 16 + 24 - 21 = 19

Therefore, the union of X and Y contains 19 elements.

The answer is :

a. If each car has space for four passengers, then the equation states how many passengers (p) may be transported by n cars:

p = 4n

where n is the number of automobiles and p is the total number of passengers.

b. By using n = 78 instead of n, we can solve for the number of passengers that could fit in 78 cars as follows:

p = 4n

p = 4(78)\sp = 312

Hence, 78 automobiles could accommodate 312 passengers.

c. By rearranging the equation, we can determine how many cars would be required to fit 78 passengers:

p = 4n\sn = p/4

When we enter p = 78 into this equation, we obtain:

n = 78/4\sn = 19.5

We would need to round up to the nearest whole number of cars, which is 20, as the number of cars must be a whole number. Hence, 20 automobiles would be required to accommodate 78 individuals.

Answer:

Step-by-step explanation:

The expression "15/18 - 7/36" can be simplified as follows:

Step 1: Find a common denominator for the two fractions. In this case, the least common denominator is 36.

Step 2: Convert both fractions to have a denominator of 36.

15/18 can be converted to 30/36 by multiplying both the numerator and denominator by 2.

7/36 can be expressed as 7/36.

Step 3: Subtract the two fractions to simplify the expression:

30/36 - 7/36 = 23/36

So the expression simplifies to 23/36.

The heaviest pack's maximum allowable weight is d = 46 - 39 = 7 kg.

Let the four packs each weight a, b, c, and d (with a <= b <= c <= d).

Using the given data, we can formulate the following six equations:

a + b = 34

a + c = 37

a + d = 39

b + c = 41

b + d = 43

c + d = 46

the fourth equation and the first equation added:

2a + 2b = 34 + 41 = 75

Solving for a, we get:

a = (75 - 2b) / 2

Substituting this into the first equation:

(75 - 2b) / 2 + b = 34

Multiplying both sides by 2:

75 - 2b + 2b = 68

Solving for b, we get:

b = 34 - (75 - 68) / 2 = 34 - 3.5 = 30.5

Substituting this value into the equation for a:

a = (75 - 2 * 30.5) / 2 = (75 - 61) / 2 = 7

The greatest possible weight of the heaviest pack is d = 46 - c. Since c <= 46 - a = 46 - 7 = 39,

The greatest possible weight of the heaviest pack is d = 46 - 39 = 7 kg.

Using x, we now know the extra height missing from the original tree height, so we add 6 to find the original.

20.88 + 6 = 26.88ft

The tree was 26.88 feet tall before the storm.

The figure which is made by placing a triangle on the small side of a rectangle has a area of 95 in.²

According to question, there is a figure made by placing a triangle with a height of 4 inches on the small side of a rectangle that measures 5 inches by 17 inches.

Small side of rectangle is 5 inches, on which triangle is placed so it becomes the base of triangle.

Area of rectangle = length × breadth

Area of rectangle = 17 × 5

so, area of rectangle is 85 in.²

Now calculate the area of triangle

Area of triangle = [tex]\frac{1}{2}[/tex] × base × height

Area of triangle = [tex]\frac{1}{2}[/tex] × 5 × 4

The probability of randomly selecting an individual in this community who has red hair or is​ left-handed is 0.23

The probability of an event refers to the likelihood of the event occurring, expressed as a number between 0 and 1.

In other words, the probability of the union of two events can be expressed as follows:

P(A or B) = P(A) + P(B) - P(A and B)

Where A represents the event of having red hair, B represents the event of being left-handed, and P(A and B) represents the probability of the intersection of the two events. In this case, P(A) = 0.08 and P(B) = 0.15.

Therefore, to find the probability of a randomly selected individual in this community who has red hair or is left-handed, we would need to know the probability of the intersection of the two events, P(A and B).

This would allow us to subtract it from the sum of the individual probabilities, P(A) + P(B), to find the total probability of having red hair or being left-handed.

=> P(A) + P(B) = 0.08 + 0.15 = 0.23

In conclusion, to find the probability of having red hair or being left-handed in this community, we would need to know the probability of the intersection of the two events, P(A and B).

1 hour = 3600 seconds

1 kilometer = 1000 meters

So, 85 km/hr = 85 x 1000/3600 m/s = 23.61 m/s

Now we can use this speed to find the distance the car travels in 3 seconds:

The freezing point is normally distributed with mean of 0 degrees celsius and a standard deviation of 1 degree celsius. The probability of getting a score between -1.5 and 2.5 is 0.9332.

To find the probability of getting a score between -1.5 and 2.5, we need to find the area under the normal distribution curve for this range using a z-score table.

First, we need to convert the range into standard units, which is done by subtracting the mean and dividing by the standard deviation:

z1 = ( -1.5 - 0 ) / 1 = -1.5

z2 = ( 2.5 - 0 ) / 1 = 2.5

Next, we look up the z-scores in a z-score table to find the area under the normal curve:

P(-1.5 < Z < 2.5) = 0.9332

This means that the probability of getting a score between -1.5 and 2.5 is 0.9332 or 93.32%.

A line must have a 2 1/2 slope in order to be perpendicular to the line whose equation is 6x + 15y = 225.

A line's slope is determined by its inclination.

M is used to signify it.

Consider Point 1 and Point 2 as the two points on a line.

The coordinates for Point 1 are (x1,y1), while the coordinates for Point 2 are (x2,y2).

The line equation was provided to us as follows:

⇒ 6x + 15y = 225

⇒ 15y = -6x + 255

⇒ y = -6/15 x + 255/15

The slope, m = -6/15

The angle of perpendicularity = -1/m

⇒ -1/(-6/15)

Reciprocal the term of denominator, and we get
