Questions
1) The formula below works out the distance travelled.
d = s x t
Where d is distance (in metres), s is speed (in metres per second) and t is time (in seconds). What is the distance covered when:
a) s is 8 m/s and t is 9 seconds
b) s is 20 m/s and t is 30 seconds
c) s is 5.5 m/s and t is 12 seconds
2) We can work out the area of a triangle by using the following formula:
Area of triangle = ½ x base x height
Work out the area of the triangle when:
a) the base is 3 cm and the height is 6 cm
b) the base is 8 cm and the height is 10 cm
c) the base is half the length of the height and the height it 12 cm
3) We have the formula below:
d = s x t
Where d is distance (in metres), s is speed (in metres per second) and t is time (in seconds). What is the distance covered when:
a) s is 8 m/s and t is 9 seconds
b) s is 20 m/s and t is 30 seconds
c) s is 5.5 m/s and t is 12 seconds
2) We can work out the area of a triangle by using the following formula:
Area of triangle = ½ x base x height
Work out the area of the triangle when:
a) the base is 3 cm and the height is 6 cm
b) the base is 8 cm and the height is 10 cm
c) the base is half the length of the height and the height it 12 cm
3) We have the formula below:
a = b2 + 7b
Find the value of a when b is 5.
4) We have the formula below.
c = d3 – 4d2 + 7d – 8
Find the value of c when:
a) d is 3
b) d is 5
5) We have the formula below (you may use a calculator for this question).
p = 4nq + 5n2 – 15nq2 + 7n2q3
Find the value of p when n is 5 and q is 2.
