Answer: Elena's running speed = 5 miles per hour.

Step-by-step explanation:

Length of track = [tex]\dfrac14 \text{ mile}[/tex]

Time taken to complete one lap = [tex]\dfrac{1}{20}[/tex] of an hour.

Elena's running speed = [tex]\dfrac{Distance}{Time}[/tex]

[tex]=\dfrac{\dfrac14}{\dfrac1{20}}\text{ miles per hour}\\\\=\dfrac{20}{4}\text{ miles per hour}\\\\=5\text{ miles per hour}[/tex]

Hence, Elena's running speed = 5 miles per hour.

Answer:

[tex]\frac{25}{10x-1}[/tex]

Step-by-step explanation:

The multiplicative inverse of "a" is " [tex]\frac{1}{a}[/tex] "

a × [tex]\frac{1}{a}[/tex] = 1

~~~~~~~~~~~

[tex]\frac{1}{5}[/tex] ( 2x - [tex]\frac{1}{5}[/tex] ) = [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex]

1 ÷ ( [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x}{25}[/tex] - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x - 1}{25}[/tex] ) = [tex]\frac{25}{10x-1}[/tex]

The multiplicative inverse of the product is  [tex]\frac{25}{10x-1}[/tex]

Step-by-step explanation:

Use the method

Change in output  / Change in input

The input progresses by 1, and y progresses by 2.

We will plug the numbers in.

2/1

Then simplify.

2/1 = 2

Hence, the rate of change is 2.

Step-by-step explanation:

20,000(0.85)6

Answer:

The correct answer is Option B: $39000

Step-by-step explanation:

Given that

Price of House = P = $650000

Rate of commission = r= 6%

In order to calculate the commission amount of Kathy, we only have to calculate 6% of $650000 or by simply multiplying the price by 0.06

So,

[tex]Commission = 6\%\ of\ 650000\\=0.06*650000\\=39000[/tex]

The commission is: $39000

Hence,

The correct answer is Option B: $39000

Answer

Answer:

c =2

Step-by-step explanation:

2(6c+2)+3c=2 (19 -c)

1. Distribute

2(6c +2 ) + 3c = 2 ( 19 - C )

12c + 4 +3c = 2 (19 - C )

2. Combine like terms

12c + 4 + 3c = 2 ( 19 - c )

15c + 4 = 2 (19 - c )

3. Rearrange terms

15c + 4 = 2( 19 - C )

15c + 4 = 2 ( -c + 19 )

4. Distribute

15c + 4 = 2 ( -c + 19 )

15c + 4 = -2c + 38

5. Subtract 4 from both sides of the equation

15c + 4 = -2c + 38

15c + 4 -4 = -2c + 38 -4

6. Simplify

Subtract the numbers

Subtract the numbers

15c = -2c +34

7. Add 2c to both sides of the equation

15c = -2 +32

15c +2c = -2c + 34 + 2c

8. Simplify

Combine like terms

Combine like terms

17c = 34

9.Divide both sides of the equation by the same term

17c = 34

17c/17 = 34/17

10. Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

c = 2

The degree of rotation about the origin will cause the triangle below to map onto itself is 360 degree.

Option A is correct.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

In the figure ABCD, is transformed to figure A'B'C'D'.

A figure will be mapped onto itself if it circles the graph 360 degrees.

As there are 360 degrees in a circle, the figure has just completed a full circle and returned to where it was before rotating.
