Anarel [89]2 years ago

Step-by-step explanation:

I guess that means

1.05 / 2.1

or

1.05 ÷ 2.1

both mean the same thing.

so, let's look at

1.05 / 2.1

this is the same as

105/100 / 210/100 = (105×100) / (210×100) =

= (105×100) / (210×100) × (1/100 / 1/100)

as long as we multiply numerator (top) and denominator (bottom) always with the same thing, the general fraction or division is unchanged.

(105×100) / (210×100) × (1/100 / 1/100) =

= (105 × 100/100) / (210 × 100/100) = 105 / 210

so, yes, the division of 105 / 210 is the same as 1.05 / 2.1

Here's the solution :

  • \dfrac{7}{ \sqrt{10 }  -  \sqrt{ 3} }

  • \dfrac{7}{ \sqrt{10} -  \sqrt{ 3}  }  \times  \dfrac{ \sqrt{10}  +  \sqrt{3} }{ \sqrt{10}  +  \sqrt{3} }

  • \dfrac{7( \sqrt{10}  +  \sqrt{3} )}{( \sqrt{ 10}) {}^{2} - (  \sqrt{ {3}})^{2}  }

  • \dfrac{7 (\sqrt{10}  +  \sqrt{3}) }{10 - 3}

  • \dfrac{7( \sqrt{10}  +  \sqrt{3} )}{7}

  • \sqrt{10} +  \sqrt{3}

Round to the nearest hundredth : 3.2649
Bas_tet [7]

Answer:

3.26

Step-by-step explanation:

Rounding to the nearest hundredth means round to the nearest two decimal places.

To do this, all we need to look at is the 3rd decimal place.

Since 4 is not 5 or greater, that means we must round down, no matter how close it is to 5.

Therefore, the answer should just be 3.26

I dont get this at all
zhenek [66]
Continuous vs discrete is if you can count vs. measure the results. For example: you can run 13. 5 miles but you can't have 13.5 dogs. Miles (measurable) are continuous while dogs (countable) are discrete. 

Qualitative results are when a result is not a number, and qualitative is when the result is a number. For example: if you're doing a lab and a result is either going to be "blue" or "green", that's qualitative, since those aren't number values. However, if you were measuring distance, that would be qualitative, since you would get a result of "6 meters" or "2.5 inches", which are numerical values. 

The scale of measurement are the units in which you are measuring something it. For example: distance has units of inches, feet, miles, etc... and weight has units of grams, kilograms, tons, etc...

Hope this helps! -Alex :)
