A hybrid car can travel 40 miles per gallon. Approximately how many gallons of fuel will the car need to travel 20 km? (5 points
-BARSIC- [3]

Answer:

<em>To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.</em>

Step-by-step explanation:

<u>Proportions</u>

The hybrid car can travel 40 miles per gallon.

Since one mile is equivalent to 1.6 Km, the distance traveled per gallon is 40*1.6 = 64 Km.

Now the distance is expressed in Km, we can find the gallons needed to travel 20 Km, by calculating 20/64 = 0.3125.

To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.

What is the sum of the integers between the square root of 12 and 40?
satela [25.4K]
1.

the closest perfect squares of 12 are 9 and 16, 

that is 9<12<16

so 
\sqrt{9}\ \textless \  \sqrt{12}\ \textless \  \sqrt{16}

3\ \textless \ \sqrt{12}\ \textless 4

this means, \sqrt{12} is  3 point something...


2.

similarly 

36<40<49

so

\sqrt{36}\ \textless \  \sqrt{40}\ \textless \  \sqrt{49}

6\ \textless \  \sqrt{40}\ \textless \ 7

which means \sqrt{40} is 6 point something...

3. 

<span>the sum of the integers between the square root of 12 and 40 is the sum of 4, 5 and 6, since 4 is the smallest integer after root 12, and 6 the greatest integer to before root of 40.
