<span>3 cans store
9 tennis balls.
Find the Constant of proportionality and write and equation with regards to
this given situation:
=> number of tennis balls = 9
=> number of cans = 3
</span>

Metric is used world-wide and is used everywhere except in english places (britan and USA)
some examples why metric is nice
base 10 system
1cm=10mm=0.1m=0.01km
1cm^3=1ml
1000cm^3=1L
1000ml=1L
0 C⁰=freezing tempurature
100 C⁰=boinling tempurature
in english
12in=1foot
3ft=1yd
16oz=1lb
8oz=1cup
3tsbs=1tbs
2c=1pt
2pt=1qt
4qt=1gal
32 F⁰=freezing
2hundred something=boiling
metric is nice because everything is in multiplules of 10
and also this exerpt from a book
"<span>In metric, one milliliter of water occupies one cubic centimeter,
weighs one gram, and requires one calorie of energy to heat up by one
degree centigrade which is 1 per cent of the difference between its
freezing point and its boiling point. An amount of hydrogen weighing the
same amount has exactly one mole of atoms in it. Whereas in the American
system the answer to <em>'How much energy does it take to boil a
room-temperature gallon of water?'</em> is go **** yourself because you
can't directly relate any of those quantities "</span>
No, Chloe didn't cut the correct amount of fabric, because she needs 0.1125 extra fabric to account for error, as an extra 15% of 0.75 yards of fabric
Answer:
It takes 30 minutes to get back
Step-by-step explanation:
Jeffery biked to the store at 12 miles per hour. This is the speed at which he biked on his way to the store. He covered this distance to the store in 20 minutes.
Converting 20 minutes to hours, we divide by 60.
20 minutes =20/60 hours
Distance which Jeffrey covers on his way to the store at a speed of 12 miles/ hour and time of 20/60 hours is
Speed = distance / time
Distance = speed × time = 12× 20/60
= 4 miles.
The distance remains the same on his way back even though his speed reduced to 8 miles/ hour
Time taken to get back = distance/ speed
= 4 /8 = 0.5 hours
Converting to minutes
0.5 × 60 = 30minutes
