Change 179km to miles. Type a whole number or a decimal. Round to four decimal places as needed.
atroni [7]

Answer:

179/1.60934 miles then divide to get the whole number/ decimal.

Step-by-step explanation:

A quick search tells me there are 1.60934 km in 1 mile.  

To convert from one unit to another there is a super simple method.  Set up a fraction with the two values, so in this case 1/1.60934  or 1.60934/1.  Which do you use?  well it depends which you are tryng to convert.

1.60934/1 has the units km/miles so since miles is on the bottom we would use it to convert miles.  That's hat you have to look at, what is in the denominator.  Since we are converting 179 km we want km on the bottom.

So we use 1/1.60934 instead because the units are miles/km.  now you just multiply the 179 by the fraction.  so the answer is 179/1.60934 miles.

Now it says we need a whole number of decimal, can you handle the division?

Number 6 part a &amp; b<br> Number 7<br> Please &amp; thank you
miv72 [106K]

Answer:

6- Part A: 750a+1200r=1000000

    Part B: 1065a+876r=1000000

Solution of the system: a\approx521.739\;\;\;\;b\approx507.246

Step-by-step explanation:

<u>Part A:</u>

In words, the equation is formed like this:

Total kg of Arabica + Total kg of Robusta = Total kg of coffee

Now, the total of each yield is calculated by the product of kg/hectare and number of hectares. Thus, the equation is:

750a+1200r=1000000

<u>Part B:</u>

In words:

Arabica's worth + Robusta's worth  = plantation worth

Each yield's worth is given by the product of the price per kg and the corresponding production. So, the equation is:

1.42(750a)+0.73(1200r)=1000000\\1065a+876r=1000000
