Examples of rates in algebra

Mathematics
1 answer:
lbvjy [14]3 years ago
7 0

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

Some examples of rate include cost rates, (for example potatoes cost R16,95 per kg or 16,95 R/kg) and speed (for example, a car travels at 60 km/h). When we calculate rate, we divide by the second value, so we are finding the amount per one unit.

If the ratio of the radii of two spheres is 6 : 5, what is the ratio of the surface areas of the two spheres?
Veseljchak [2.6K]
Answer: Choice C) 36:25

To get this answer, we simply square each piece of the original ratio 6:5
6^2 = 36
5^2 = 25

Think of two squares where one has a side length of 6 and the other of 5. The ratio of the sides is 6:5. The areas of the two squares are 36 and 25 as mentioned above. So the ratio is 36:25. This idea can be applied to any surface area or area in general. It doesn't have to be two squares. The reason why we can apply this to any general shape is because we can break up the shape into small squares to get a rough approximation. The more squares we use, the better the approximation.
