Answer:
Step-by-step explanation:
Given : The fuel efficiency of car = 7.6 km per kilogram
We also given that
1 mile = 1.609 km
Then,
1 gallon = 3.785 liters
1 liter of gasoline = 0.729 kg
Then,
Now, the fuel efficiency of car will be :
Hence, the car’s fuel efficiency in miles per gallon= 4.5
Rectangular with whole numbers
perimiter=legnth+legnth+width+width=2l+2w
therefor
p=2l+2w=2(l+w)
p/2=l+w
perimiter=20
20=2l+2w
divide by 2 to make simpler
10=l+w
find all combos
l>w so
l=9 and w=1
l=8 and w=2
l=7 and w=3
l=6 and w=4
combos
Answer:
416.01
Step-by-step explanation:
49% is the same as 0.49
0.49 × 849 is 416.01
Answer:
Unless im being completely braindead right now there isn't a whole number that works with this. When simplified its 5/2 or 2.5 but because it isn't an actual whole number (like 2, 4 and 6) they don't count.
