Examples of rates in algebra
lbvjy [14]

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.

Nat2105 [25]

Answer:

a.) First check on the height of the bar that ranges between 20 and 24 which is 6. The 6 is the number of students who bought 20 books or more, so get the percentage of those students who bought 20 or more books; divide 6 which is the number of students who bought 20 books or more with the total number of students which is 40 then multiply with 100.

% of students who bought 20 or more books = 6/40 ×100

=15

Step-by-step explanation:

b.) Find the area of a trapezium

= 1/2 × {a+b} × h

= 1/2 × {9 + 13} ×12

= 132

= 1/2 × {13 + 6} × 12

= 108

Mean no. of books bought = 132 + 108

= 240
