Answer:
After 15 minutes, the temperature of both the furnaces will be same.
Step-by-step explanation:
Let
be the minutes when the temperature of both becomes same.
Now, as per question:
Temperature of the furnace after
minutes that is cooling at the rate of 15 degree per minute is given as:

Temperature of the furnace after
minutes that is heating at the rate of 5 degree per minute is given as:

Now, equating both the temperatures, we get

Therefore, after 15 minutes, the temperature of both the furnaces will be same.
In slope-intercept form, the y variable is isolated.
so,
<span>13+5y=6x
Subtract 13 on both sides.
5y=6x-13
Divide by 5 on both sides.
y=6/5 x -13/5</span>
Answer:
32
Step-by-step explanation:
1,024 will be a perfect square if it is the product of 2 of the same numbers:
Calculate the square root of 1024:

= 32
So, the number is 32
