Answer:

Cosine Rule (The Law of Cosine)

The Cosine Rule states that the square of the length of any side of a triangle equals the sum of the squares of the length of the other sides minus twice their product multiplied by the cosine of their included angle.

a² = b² + c² - 2bc Cos A

where,

a,b,c are sides of a triangle

A is the included angle

The base of a solid crate has an area of 6 square meters.The height of the crate is 4 meters. What is the volume of the crate?
professor190 [17]

Given is the base area of a solid crate, B = 6 square meters.

Given is the height of the solid crate, H = 4 meters.

We know the formula for volume of any solid is given as follows :-

(Volume of the solid) = (Base area of the solid) x (Height of the solid).

Volume = B x H.

Volume = (6 square meters) x (4 meters).

Volume = 24 cubic meters.

Hence, the volume of the solid crate would be 24 cubic meters.

The amount of energy, E, required to raise the temperature, T, of a container of water is E=240T, where E is measured in calorie
SSSSS [86.1K]
<span>E=240T

For the lower limit of energy:
E=12,000 cal

so 12000 = 240 T            >>>      T = 50</span> degrees Celsius

<span>For the upper limit of energy:
E=18,000 cal

so 18000 = 240 T            >>>      T = 75 </span>degrees Celsius

The difference in temperature = 75 - 50 = 25 <span>degrees Celsius
