Answer:
It would take 4 hours for both candles to be the same height
Step-by-step explanation:
Total time (t) for red candle to be same height (h) can be expressed as;
Final height after time t=Initial height-rate per hour
where;
Final height after time=h
Initial height=8 inches
Rate per hour=rate×time=(7/10)×t=0.7t
Substituting;
h=8-0.7t
Total time (t) for blue candle to be same height (h1) can be expressed as;
Final height after time t=Initial height-rate per hour
where;
Final height after time=h1
Initial height=6 inches
Rate per hour=rate×time=(1/5)×t=0.2t
Substituting;
h1=6-0.2t
Since h=h1
8-0.7t=6-0.2t
8-6=0.7t-0.2t
0.5t=2
t=2/0.5
t=4 hours
It would take 4 hours for both candles to be the same height
The answer would be %0.37 because you do $1.00-$0.63
You have to find the greatest number that divide 294, 252 and 210, i.e., the greatest common factor.
Then, you need to factor each number and calculate the product of the common factors raised to the lowest exponent.
294 = 2*3*7^2
252 = 2^2 * 3^2 * 7
210 = 2*3*5*7
Greatest common factor = 2*3*7 = 42
The biggest possible number of students to distribuute the balls equally is 42
