The temperature of the furnace is 1200 and cool at a rate of 15 per minute the temperature of another furnace is 900 and is heat
Hunter-Best [27]

Answer:

After 15 minutes, the temperature of both the furnaces will be same.

Step-by-step explanation:

Let x be the minutes when the temperature of both becomes same.

Now, as per question:

Temperature of the furnace after x minutes that is cooling at the rate of 15 degree per minute is given as:

T=1200-15x

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

T=900+5x

Now, equating both the temperatures, we get

1200-15x=900+5x\\1200-900=15x+5x\\300=20x\\x=\frac{300}{20}=15\ min

Therefore, after 15 minutes, the temperature of both the furnaces will be same.

bekas [8.4K]

Answer:

x = \sqrt{30}

Step-by-step explanation:

Using the Altitude- on- Hypotenuse theorem

(leg of Δ ABC )² = (part of hypotenuse below it ) × ( whole hypotenuse )

x² = 3 × (3 + 7) = 3 × 10 = 30 ( take the square root of both sides )

x = \sqrt{30}

If 1/2 cup of soup equals 120 milliliters, then how many milliliters are in 3 1/2 cups of soup?
pav-90 [236]
Ok. So since they give you that 1/2 cup of soup equals 120 milliliters it makes this very easy. So since we know 120milliliters=1/2 and that 3 1/2= 7 1/2s (please note that the 7  1/2s doesnt mean seven and 1/2 it means seven 1/2s) you just add 120 to itself 7 times getting an answer of 840. (please vote brainliest ^^)
