2/3 is about .66 so do .66 divided by 9 and you get .073
Answer:
40%
Step-by-step explanation:
10/4 = .4
.4 = 40%
Answer:
21.6 liters
Step-by-step explanation:
40 drops make up a volume of 10 mL
Therefore, the volume of 1 drop of water = 10mL/40 = 1/4 mL= 0.25mL
Since the tap loses 1 drop of water in 1 sec, it loses 0.25mL of water in 1 second
60 seconds make up 1 second so volume of water lost in 1 minute = 0.25 x 60 = 15 mL
60 minutes make up 1 hour so volume of water lost in 1 hour = 15 x 60 = 900 mL
24 hours make up a day so volume of water lost in 1 day = 900 x 24 = 21,600 mL
Since 1000 mL make up 1 liter, divide by 1000 to get volume in liters
Volume of water lost in 1 day = 21600/1000 = 21.6 liters
Can be done as one equation
V lost in one day = 0.25 x 3600 x 24 mL = 21600 mL = 21.6 L
I think the ratio is for for every 4 packs it cost 10 dollars so in all it would cost 30 dollars
Answer:
Hey!
To start this problem, we'll most likely need a calculator. Handling
can get a little messy, and tricky.
(also note that "pie" is a food, the mathematical term
, is pronounced "pie", but spelled "pi.")
Anyway, multiplying 3.14159265359..... (
)
160 = 502.654824574...... going on and on.
In general, these types of problems are better for a calculator if you want an exact answer. Otherwise, just resort to estimation.
is pretty close to 3.14.
160
3.14 = 502.4, which is decently close to our other answer.
Hope this helps!
