Given :

Three trolley tours leave from the same stop at 9:00 am.

Tour A returns to the stop every 75 minutes, Tour B returns every 60 minutes, and Tour C returns every 40 minutes.

To Find :

In how many hours will all three tours return to the stop at the same time.

Solution :

We know, they will return to the stop at the same time is the L.C.M of three i.e 75, 60 and 40 minutes.

So, their L.C.M is :

L.C.M = 600 minutes.

Now, 600 minutes = 600÷60 hours = 10 hours.

Therefore, they will all meet at stop in 10 hours.

Hence, this is the required solution.

The approximate measure of angle YZX is 39.4°. Option(B) is the correct answer.

we know that

In the right triangle XYZ

\(tan(Y Z X)= \frac{opposite side angle YZX}{adjacent side angle YZX}\)

In this problem,

Opposite side angle YZX= XY = 12.4cm

Adjacent side angle YZX= YZ = 15.1cm

substitute the values,

\(tan ( Y Z X) = \frac{12.4}{15.1}\)

\(Angle ( Y Z X) = arc tan( \frac{12.4}{15.1} )\)

Angle ( Y Z X) = 39.4°

So,  the approximate measure of angle YZX is 39.4°.

The two states are Arizona and New Mexico.

Arizona and New Mexico are two states with unique demographics that differ from the rest of the United States.

Thus, these states are characterized by a high Latino population and, in addition, a high percentage of native population. This, due to its proximity to the border with Mexico.

Thus, Arizona has counties like Apache County, where 70% of its population is native; and like Yuma County, where 51% of its population is Hispanic.

In turn, New Mexico has counties like McKinley County, where 75% of its population is native; and as Hidalgo County, where 55% of its population is Hispanic.

Answer:

x= -1/2 and -32

y = -10

Step-by-step explanation:

1) 2(-4x-8y)= (-48)2

8x+3y =-34

*to create a way to cancel out the x*

2) -8x-16y= -96

8x+3y= -34

*add them

-8x +8x =0

-16y + 3y = -13y

-96+ -34= -130

3) -13y =-130

isolate y

4) y = -10

*plug in* to find x into both original equations*

5) 8x + 3(-10) = -34. -4x-8(-10)= -48

*follow order of operations to solve for x

6) 8x -30 =-34. -4x +80 = -48

7) 8x =-4. -4x =128

8) x= -1/2. x = -32

Step-by-step explanation:

let the number be x

and according to question,

six + 2 times a number = 2x + 6

26 + 6 times a number = 6x + 26

→ 2x + 6 = 6x + 26

→ -6x + 2x = 26 - 6

→ -4x = 20

→ x = 20/4 = 5

→ x = 5

we can calculate the partial derivatives with respect to x and y, evaluate them at the given point, and use them to form the equation of the tangent plane. The equation for the tangent plane is z = -12x - 28y - 79.

To determine the equation for the tangent plane at the point (2, -3), we need to find the partial derivatives of f(x, y) with respect to x and y.

The partial derivative with respect to x, denoted as ∂f/∂x, can be obtained by differentiating f(x, y) with respect to x while treating y as a constant. ∂f/∂x = -y^2 + 3x^2.

The partial derivative with respect to y, denoted as ∂f/∂y, can be obtained by differentiating f(x, y) with respect to y while treating x as a constant. ∂f/∂y = -2xy - 7.

Next, we evaluate the partial derivatives at the given point (2, -3):

∂f/∂x = -(9) + 12 = 3,

∂f/∂y = -2(2)(-3) - 7 = 1.

Using these values, we can form the equation for the tangent plane:

z = f(2, -3) + ∂f/∂x(x - 2) + ∂f/∂y(y - (-3)),

z = (-2(-3)^2 + 2^3 - 7(-3) - 4) + 3(x - 2) + 1(y + 3),

z = -12x - 28y - 79.

Therefore, the equation for the tangent plane of f at the point (2, -3) is z = -12x - 28y - 79.

Answer:

slope:(-0.5) y-intercept:0 equation:(-0.5x)

Step-by-step explanation:

To find slope, you use the formula y2-y1/x2-x1

For example, I used the first 2 sets of coordinates used in the table

(-2,1)&(-1,0.5)

First Part: 0.5-1= -0.5

Second part: -1-(-2)=1

Third Part: -0.5/1=(-0.5)

Y-intercept: In order to find the y-intercept, x needs to be 0.

Y-intercept=0

Equation:

The form for the equation should be, mx+b

B=Y-intercept

M=Slope

X=variable

The slope is -0.5 and you add the x after -0.5

Since the y-intercept is 0, it doesn't have a value so putting 0 at the end would be unnecessary. Slope:-0.5x

The probability of drawing a pair when selecting three cards at random from a standard 52-card deck is approximately 0.1694, or about 16.94%.

To calculate the probability of drawing a pair of cards from a standard 52-card deck when selecting three cards at random, we need to consider the number of favorable outcomes (pairs) and the total number of possible outcomes.

First, let's determine the number of favorable outcomes. For a pair, we need two cards of the same rank (e.g., two 7s, two Queens, etc.) and any third card that is different from the pair.

The number of ways to choose a rank for the pair is 13 (one for each rank). For each rank, there are four cards of that rank in the deck. Therefore, the number of ways to select two cards of the same rank is given by:

Number of ways to choose a pair = 13 * (4 choose 2) = 13 * 6 = 78

After selecting the pair, there are 50 cards remaining in the deck. The third card must be of a different rank from the pair. There are 48 cards remaining with different ranks from the pair.

Therefore, the number of favorable outcomes (pairs) is 78 * 48 = 3,744.

Next, let's calculate the total number of possible outcomes when selecting three cards from a standard deck. The total number of ways to choose any three cards from 52 cards is given by:

Total number of possible outcomes = (52 choose 3) = 22,100

Finally, we can calculate the probability of drawing a pair:

Probability of drawing a pair = Number of favorable outcomes / Total number of possible outcomes

= 3,744 / 22,100

≈ 0.1694

Therefore, the probability of drawing a pair when selecting three cards at random from a standard 52-card deck is approximately 0.1694, or about 16.94%.

The supremum of the set A does not exist (it is negative infinity), and the infimum of the set A is 1.

To define the supremum and infimum of the set A, we first need to determine the properties of the set.

The set A is defined as A = {(x-3)/(x-2) ∈ R : x < 0}.

To find the supremum (also known as the least upper bound) of A, we need to find the smallest value that is greater than or equal to all the elements of A. In other words, we are looking for the least upper bound of the set A.

Let's analyze the elements of A:

For x < 0, the expression (x-3)/(x-2) can take on different values depending on the value of x. We need to find the maximum value that this expression can reach for all x < 0.

As x approaches 0 from the left side, (x-3)/(x-2) approaches negative infinity. Therefore, there is no finite supremum for the set A.

Next, let's find the infimum (also known as the greatest lower bound) of A. We need to find the largest value that is less than or equal to all the elements of A. In other words, we are looking for the greatest lower bound of the set A.

Again, analyzing the elements of A:

As x approaches negative infinity, (x-3)/(x-2) approaches 1. Therefore, the infimum of the set A is 1.

4 gallons is 4 times 1 gallon. so, of course, we need to apply the same factor to the other side too.

4 gallons = 4×3.79 = 15.16 ≈ 15 liters

Using proportions, it is found that:

a) The graph for the distance-time journey is given at the end of the answer.

b) The average speed for the whole journey was of 25 miles per hour.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations such as multiplication or division from the rates of the variables.

Proportions are applied to find the relation between velocity, distance and time, as velocity is distance divided by time, that is:

v = d/t.

Then, applying cross multiplication, the distance is given by:

d = vt.

On the first interval of his trip, for the first 15 minutes = 1/4 of an hour, he traveled at a velocity of 40 mph, hence the distance is:

d = 40 x 1/4 = 10 miles.

During the second interval, of 25 minutes, from 15 minutes to 40 minutes, he stopped, hence his distance remained constant at 10 miles.

During the third interval, of 20 minutes = 1/3 of an hour, Tim completed the journey at a velocity of 45 mph, hence the complete distance is given by:

d = 10 + 45 x 1/3 = 10 + 15 = 25 miles.

The graph with these three intervals is given at the end of the answer.

He drove a distance of 25 miles in one hour, hence his average speed is given as follows:

v = d/t = 25/1 = 25 miles per hour.
