Step-by-step explanation:

Given that,

Distance, d = 10.5 km = 10500 m

Time, t = 8 minutes = 480 s

We need to find the unit rate of a train motion. The distance divided by time is equal to the speed of the object.

[tex]\text{Rate}=\dfrac{\text{Distance}}{\text{time}}\\\\=\dfrac{10500\ m}{480\ s}\\\\=21.87\ m/s[/tex]

So, the unit rate is 21.87 m/s.

Answer:

d. 0.27

Step-by-step explanation:

Calculation to determine the probability that a corn crop has either an ear worm infestation, a corn borer infestation or both

Using this formula

P(E U B) = P(E) +P(B) -P(E n B)

Let plug in the formula

P(E U B) =0.24 + 0.16 -0.13

P(E U B)=0.27

Therefore the probability that a corn crop has either an ear worm infestation, a corn borer infestation or both will be 0.27

Answer:

0.07

Step-by-step explanation:

From the question, a given grid was divided into a definite number of squares with some of the squares shaded.

Total number of squares in the grid = 100

number of shaded squares in the grid = 7

Thus, 7 squares are shaded out of 100 square in the grid.

So that this can be expressed in fraction as;

[tex]\frac{number of shaded squares}{total number of squares}[/tex] = [tex]\frac{7}{100}[/tex]

                                = 0.07

The decimal number of the squares represented is 0.07.

Answer:

1/21

Step-by-step explanation:

Answer:

1/21

Step-by-step explanation:

6/126 = 1/21 because 6 divided by 6 equals 1 and 126 divided by 6 equals 21.

Complete whatever squares you can:

x² - 12x = x² - 12x + 36 - 36 = (x - 6)² - 36

y² - 2y = y² - 2y + 1 - 1 = (y - 1)² - 1

So rewrite the equation as

x² + y² + z² = 12x + 2y

→   x² - 12x + y² - 2y + z² = 0

→   (x - 6)² - 36 + (y - 1)² - 1 + z² = 0

→   (x - 6)² + (y - 1)² + z² = 37

Then the center is (x, y, z) = (6, 1, 0), and its radius is √(37).

Answer:The radius is the square root of the constant term, z

=======================================================

Explanation:

Check out the diagrams below. I posted two of them. Start with figure 1.

Notice how I've copied the first two columns and placed them on the right side of the matrix.

After that, I've highlighted the diagonals. The numbers in each diagonal grouping multiply together. I've used color coding to show this.

Once you find all those products, you add up the values. Figure 1 shows a result of 42. This isn't the final answer, but it helps us get there.

Figure 2 is a similar idea, but we're doing the off diagonals instead of the main diagonals. The result here is 15.

The last step is to subtract the results found in figures 1 and 2. We get 42-15 = 27 as the final answer.

You could use co-factor expansion as an alternative method. For me, I prefer this method of multiplying diagonals. Unfortunately the method only works for 3x3 matrices.

The scale factor will create a similar triangle and thus there will be no change in angles so angles will still be 30° 60° and 90°.

You must specify the extent of the shape's enlargement when describing one.

The scale factor is the ratio of two dimensions such that one figure is large and another is small.

The scale factor is done due to the unpractical measurement of any figure.

Scale factor gives either a small or big similar image of a triangle, for example, if we have a triangle with vertices 2,4,6 and it is scaled by 1/2 then the resultant dimension will 1,2,3 but angles still remain the same.

Hence "The scale factor will create a similar triangle and thus there will be no change in angles so angles will still be 30° 60° and 90°".

Answer:

4500

Step-by-step explanation:

As long as your number isn't less than 500, it will always round up.

The required least weight of the elephant is 4500 pounds.

Given that,
When rounded to the nearest thousand an elephant weight is 5,000 pounds. What is the least amount the elephant could weigh is to be determined.

The process in mathematics to operate and interpret the function or expression to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here, in the question, the rounded value of the elephant is given which is 5000 pounds, the least value that can be round to the nearest hundred is 4500.

Thus, the required least weight of the elephant is 4500 pounds.

Answer:

1) x = 7

2) x = 15

3) x = 19

4) x = 2

5) x = - 6

6) x = 10

7) x = 17

Step-by-step explanation:

1) 2x + 5= 12 +x

  -x                -x

2x -x + 5 = 12

          -5     -5

x = 7

2) 5x = 30 + 3x

   -3x          -3x

2x = 30

x = 15

3) 2 + x/3 = 7

3(2 + x/3) = (7) 3

2 + x = 21

-2         -2

x = 19

4) 15 - x = 17 - 2x

       +2x       +2x

15 - x + 2x = 17

-15               -15

x = 2

5) 6x = - 42 - x

   +x            +x

7x = -42

x = - 6

6) 36 - 4x = 26 - 3x

         +3x           +3x

36 - x = 26

-36        -36

-x = -10

x = 10

7) -2 + x = 15

   +2         +2

x = 17

Answer:

10 melons

Step-by-step explanation:

The rate of change is 10.

30 : 1

300 : x

Multiply 30 x 10 to get 300. And you do the same to 1 and x. So, 1 x 10 = 10. So x = 10

So it would look like this -

30 : 1

300 : 10
