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?

Margaret [11]

Answer:

Two real world situations are shown below.

Step-by-step explanation:

Initial population of a certain bacteria is 1 thousand and the population doubles in each hour. So, population of bacteria (in thousands) after x hours is

f(x)=1(2)^x

f(x)=(2)^x

A person invests 1 lakh rupees in shares and the amount is twice at the end of each year. So, total amount (in lakhs) after x years is

f(x)=1(2)^x

f(x)=(2)^x
