True. The variables x, y, and z have each been assigned an integer value.

Here is a fragment of code that assigns the least of three integer variables to another variable named min:

min = x  # initialize min to the value of x

if y < min:  # check if y is less than min

   [tex]min = y[/tex] # [tex]update min to the value of y if y is less than min[/tex]

if z < min:  # check if z is less than min

   [tex]min = z[/tex] # [tex]update min to the value of z if z is less than min[/tex]

In this code, the variable 'min' is first initialized to the value of 'x'. Then, the code checks if 'y' is less than 'min', and if so, updates the value of 'min' to 'y'. Finally, the code checks if 'z' is less than 'min', and if so, updates the value of 'min' to 'z'. At the end of this code fragment, the variable 'min' will contain the least of the three variables 'x', 'y', and 'z'.

The equations are two parallel lines, then the system of equations has no solutions.

Here we have a system of equations:

-7x + 7y = 1

2x - 2y = -18

Now, if we multiply the second equation by (7/2) we will get:

(7/2)*(2x - 2y) = -18*7/2

7x - 7y = -63

If we multiply this by -1 we will get:

-1*(7x - 7y) = -1*-63

-7x + 7y = 63

Then the system of equations becomes:

-7x + 7y = 1

-7x + 7y = 63

Answer:

  105°

Step-by-step explanation:

You want the measure of the remaining angles of a pentagon if one of the angles is 120° and the remaining angles are congruent to each other.

The sum of the interior angles of a pentagon is 180* × (5 -2) = 540°. If one of the angles is 120°, the sum of the other four is ...

  540° -120° = 420°

Then each of those four congruent angles has a measure of ...

  420°/4 = 105°

The size of the other angles is 105°.

According to the unit conversion table, there are 21.3 dL in 9 cups.

We are asked to find there are how many deciliters which is equivalent to 9 cups,

Since,

The length and width of the rectangular board is 27 inches and 23 inches respectively

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the mat be = 184 inches²

Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Let the area of the larger rectangle be = ( 2x - 3 ) ( x + 8 )

Let the area of the smaller rectangle be = ( 2x - 7 ) ( x + 4 )

Now , the area of mat = area of the larger rectangle - area of the smaller rectangle

So , 184 = ( 2x - 3 ) ( x + 8 ) - ( 2x - 7 ) ( x + 4 )

On simplifying the equation , we get

2x² - 3x + 16x - 24 - [ 2x² + x - 28 ] = 184

On further simplification , we get

12x + 4 = 184

Subtracting 4 on both sides of the equation , we get

12x = 180

Divide by 12 on both sides of the equation , we get

x = 15

So , the length of the board = ( 2x - 3 ) = 27 inches

And , width of the board = ( x + 8 ) = 23 inches

Hence , the dimensions of the rectangular board is 27 x 23 inches²

Answer:

141 cm^2

Step-by-step explanation:

Given: V = 104 cm3, h = 8 cm

Since V = Bh, where B is the area of the base, and h is the height of a prism, then

B = V/h substitute the given values:

B = 104 cm3/8 cm

B = 13 cm2, which tells us that the long side of the square base equals the square root of 13.

The surface area of a prism = L.A. + 2B, where L.A. is the lateral area of the prism.

L.A. = pH, where p is the perimeter of the base.

Since p = 4(square root of 13) cm, h = 8cm, and B = 13 cm2, we have:

Surface Area = pH + 2B = [4(square root of 13) cm](8 cm) + 2(13 cm2) = 115.38 cm2 + 26 cm2 = 141 cm2

Thus, the surface area of the prism is approximately 141 cm2.

The measure of angles ∠DEM and ∠MEF will be the same which is 41.8 degrees.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Adjacent angle - In math, two points are nearby in the event that they have a typical side and a typical vertex.

EM bisects DEF and ∠DEF = 83.6°. Then the measure of the angle ∠DEM and ∠MEF will be the same. Then we have

∠DEM + ∠MEF = ∠DEF

∠DEM + ∠DEM  = 83.6°

2∠DEM = 83.6°

∠DEM = 41.8°

The measure of angles ∠DEM and ∠MEF will be the same which is 41.8 degrees.

The type of sampling method used by Mrs. Trahan is clustering method. The correct option is 4.

A population is divided into many clusters that are representative of homogenous traits and have an equal probability of being included in the sample using the sampling technique known as cluster sampling.

Using this sampling approach, researchers examine a sample that includes a variety of sample criteria, including demographics, lifestyle, background, or any other population characteristic that may be the subject of the research being done. This approach is typically used when a statistical population is made up of comparable but internally heterogeneous groupings. Cluster sampling divides the population into smaller, more productive groups, allowing the researchers to obtain data without picking the full population.

Check the picture below.

The statement that describes the relationship is: option B.

The situation that can be represented by the equation y = 12x is: B. "Yvonne has y dollars. This is one half more dollars than her friend Marie who has x dollars."

In the equation y = 13x, y is equal to 13 times x. This means that y increases by a factor of 13 for every increase in x.

In the equation y = x + 13, y is equal to x plus 13. This means that y is always 13 more than x.

Therefore, the answer is:

B. "In y = 13x, the value of y is 13 times the value of x, and in y = x + 13, the value of y is 13 more than the value of x."

The equation y = 12x means that y is equal to 12 times x. In the given situation, Yvonne has y dollars and Marie has x dollars. Yvonne has 12 times more dollars than Marie, and one half more than Marie. Therefore, the situation can be represented by y = 12x.

Answer: When Mohammed meets Han Fei, she will be 74.6 kilometers away from San Francisco.

Step-by-step explanation:

First, we need to convert Mohammed's speed from miles per hour to kilometers per hour, as Han Fei's speed is given in kilometers per hour.

40 miles per hour = 64.37 kilometers per hour (approximately)

Now, let's determine how long it will take Mohammed to reach the point where he meets Han Fei:

time = distance ÷ speed

time = 240 km ÷ 64.37 km/h

time ≈ 3.73 hours

So, after 3.73 hours, Mohammed will meet Han Fei.

In that time, Han Fei will have traveled:

distance = speed × time

distance = 20 km/h × 3.73 h

distance ≈ 74.6 km
