Answer:

\frac{3}{ {x}^{6} }

Step-by-step explanation:

\frac{6 {x}^{3} }{2x {}^{9} }

Using the division property of power,

\frac{ {x}^{n} }{ {x}^{m} }  = x {}^{n - m}

6 and 2 are the real numbers so just divide 2 by 6.

\frac{6 {x}^{3} }{2 {x}^{9} }  =   \frac{6}{2}  {x}^{3 - 9}

3x {}^{ - 6}

Using the negative properties of power

x {}^{ - n}  =  \frac{1}{x {}^{n} }

Make sure the coefficient in front x, is the numerator.

Since 3 is our coefficient, it will be 3.

\frac{3}{ {x}^{6} }

There is 3600 seconds per hour.
 Multiply the speed per second by 3600 to get the speed in miles per hour then convert to kilometer/hour.

4.9 * 3600 = 17,640 miles per hour

17,640 x 1.6 = 28,224 kilometers per hour

CAN SOMEBODY HELP WITH THIS QUESTION ASAP​
tia_tia [17]

Answer:

The rectangles are not similar

Step-by-step explanation:

In order to check whether they are similar, we need to take the ratio of their similar sides and ensure they are equal to a constant k.

Hence;

AB/PL = AD/LM = k

32/26 = 18/12 = k

16/13 = 9/6 = k

Since the scale factor is not the same, hence the rectangles are not the same.

timothy is planting a garden. Tulips cost $125 per bub. The total cost c of his gardening supplies is $1.25 per bub b plus $10 f
N76 [4]

Answer:

Independent variable = number of bub (b)

Dependent variable = total cost (c)

Equation: c = $1.25b + $10

Timothy would spend: $20

Step-by-step explanation:

Total cost = c

Number of bub = b

✔️Total cost, c, is dependent on the number of bub, b.

Therefore:

Independent variable = number of bub (b)

Dependent variable = total cost (c)

✔️Equation that describes this situation can be written as:

c = $1.25b + $10

✔️If Timorhy buys 8 bubs, he would spend the following:

Substitute b = 8 into c = $1.25b + $10, and solve for c.

c = $1.25(8) + $10

c = $10 + $10

c = $20

What is an equation of the line that passes through the point (−3,−1) and is perpendicular to the line x-2y=6?
gogolik [260]

Answer:

y = 2x+5

Step-by-step explanation:

rearrange the equation to make y the sof

y = 1/2x - 3

to find gradient of perpendicular line

1/2 ÷ ( - 1 )

y = -2x + c , the replace the coordinates (-3,-1)

y = 2x + 5
