Calculate the unit rate:<br>write your answer as a decimal <br><br>1/2 mile in ever 1/3 hour​
Alexandra [31]

Answer:

unit \: rate =  \frac{distance}{time}

unit rate is similar to speed / velocity:

unit \: rate =  \frac{ (\frac{1}{2} )}{ (\frac{1}{3})} \\  \\  =  \frac{1}{2}  \div  \frac{1}{3}  \\  \\  =  \frac{1}{2}  \times  \frac{3}{1}  \\  \\  = >  { \boxed{ \boxed{unit \: rate  =   \frac{3}{2}  \: miles \: per \: hour}}}

[<em>unit</em><em> </em><em>rate</em><em> </em><em>must</em><em> </em><em>have</em><em> </em><em>units</em><em> </em><em>including</em><em> </em><em>per</em><em> </em><em><</em><em>time</em><em>></em><em> </em>]

The line 2x + 3y = -6 intersects the x axis at (a,0) and the y axis at (0,b) what is a + b ?
USPshnik [31]
2x + 3y = -6 (Subtract 2x from both sides)
3y = -2x - 6 (Divide both sides by 3 to isolate x) which will give you y = -2/3x - 2 and this graphed would cross the x-axis at (-3,0) and the y-axis at (0, -2). So a + b = -5

Which shows 0.124 in expanded form? A. ( 1 × 1 10 ) + ( 2 × 1 100 ) + ( 4 × 1 1000 ) B. 1 + ( 2 × 1 100 ) + ( 4 × 1 1000 ) C. 1
iren [92.7K]

Answer:

A. ( 1 × 1 / 10 ) + ( 2 × 1 / 100 ) + ( 4 × 1 / 1000 )

Step-by-step explanation:

A number is written in expanded form if it shows the sum of the values of the individual digits that make up the number.

To write 0.124 in expanded form, follow these steps:

<em>(i) Take the digits one after the other and multiply it by its value depending on its place. </em>

<em>Taking the first digit </em>- 0

The value is 0 unit, where a unit is 1

<em>Now multiply 0 by 1</em>

=> 0 x 1

=> 0

<em>Taking the second digit </em>- 1

The value is 1 tenth, where a tenth is 1 / 10

<em>Now multiply 1 by 1 / 10</em>

=> 1 x 1 / 10

<em>Taking the third digit </em>- 2

The value is 2 hundredth, where a hundredth is 1 / 100

<em>Now multiply 2 by 1 / 100</em>

=> 2 x 1 / 100

<em>Taking the fourth digit </em>- 4

The value is 4 thousandth, where a thousandth is 1 / 1000

<em>Now multiply 4 by 1 / 1000</em>

=> 4 x 1 / 1000

<em>(ii) Add the results obtained in (i) above</em>

=> (0 x 1) + ( 1 x 1 / 10) + (2 x 1 / 100) + ( 4 x 1 / 1000)

=> ( 1 x 1 / 10) + (2 x 1 / 100) + ( 4 x 1 / 1000)

Therefore,

0.124 in expanded form is  ( 1 × 1 / 10 ) + ( 2 × 1 / 100 ) + ( 4 × 1 / 1000 )
