A furnace delivers 8.0 × 104 btu per hour. how many kilocalories per hour is this?
vazorg [7]
For this case the first thing you should know is the following unit conversion.
 1 BTU = 0.25 Kilocalories
 We then have the following numerical value:
 8.0 * 10 ^ 4 \frac{BTU}{h}
 Applying the conversion of units we have:
 8.0 * 10 ^ 4 \frac{BTU}{h} * 0.25 \frac{Kcal}{BTU}
 Canceling units we have:
 20000 \frac{Kcal}{h}
 Answer:
 
This is 20000 kilocalories per hour
 
20000 \frac{Kcal}{h}

The sum of 2 consecutive integers is one less than 3 times the smaller integer find the 2 integers
aalyn [17]

The two consecutive integers are 2 and 3

<em><u>Solution:</u></em>

Let x and x + 1 are the two consecutive integers

Let "x" be the smallest integer

Let "x + 1" be the larger integer

<em><u>Given that, sum of 2 consecutive integers is one less than 3 times the smaller integer</u></em>

Therefore,

sum of 2 consecutive integers = one less than 3 times the smaller integer

sum of 2 consecutive integers = 3 times the smaller integer - 1

x + x + 1 = 3(x) - 1

2x + 1 = 3x - 1

3x - 2x = 1 + 1

x = 2

Thus the smaller integer = x = 2

Larger integer = x + 1 = 2 + 1 = 3

Thus the two consecutive integers are 2 and 3
