Answer:
4
Step-by-step explanation:
Candle is lit every 10 minutes :
Number of candles lit in 55 minutes:
Starting from 0 minute ; Numbe rod candles lit on 55 minutes = 6
1st candle burns out after 40 minutes
Second burns out after 50 minutes
Third will burn out after 60 minutes
Hence Number of candles still burning :
Number of candles lit - Number of candle burnt out
6 - 2 = 4 candles

Ok. To convert anything into anything else you do something very very simple. Divide what you want...by what you have. For example, if I have 15 liters of water, I'm going to multiply by gallons over liters. Multiply the measurement given by what you want, then divide that by what you have.
You take the higher unit and make that 1, then however many of the other units you can fit and that's the other number. That can become 1 gallon / 3.79 liters, or 30m / 3000cm, etc.
So you have 15 liters, you want it in gallons, and it takes four gallons per liter:
15 liters x 1 / 3.79
= 4 gallons (3.9577836 gallons unrounded)
This works because you are dividing the measurement given by how many units of that measurement it takes to fit in another measurement. However, I prefer this method because it makes it easier to figure out when to multiply into smaller units, or divide to get bigger units.
How to convert: measurement x want / have
Answer:
interest = $600
Step-by-step explanation:
for simple interest,
I = PTR/100
Principal (P) = $5000
Time (T) = 3 YEARS
Rate(R) = 4%
therefore, Interest (I) = $5000 × 3 × 4 / 100
= $ 600

Answer:
14.4 or 15 bags
Step-by-step explanation:
The number of yards covered by x bags is ...
(3 1/2)x = 50 1/4
x = (50 1/4)/(3 1/2) = 50.25/3.5 ≈ 14.4*
We assume that bags of chips are available only in integer quantities.
The PTA will need 15 bags of wood chips to cover the wet section.
_____
* The exact answer is 14 5/14. We hope that an integer number is the desired solution, as anything more precise than that seems inappropriate in this context.
