The nth term of a sequence is given by 2n 2 − 5
Find the difference between the 3rd term and the 7th term of the sequence. A different sequence is generated. After the first term the sequence is generated by using the rule “multiply the previous term by d and then add 2” The first term of the sequence is 2 x 1 The second term of the sequence is 4 x 9 The third term of the sequence is 20 x 11 Given that 2 x 1

A large rental company has cars, vans and minibuses available to rent. The cost to rent a minibus from the company is found by adding $1000 rental fee $400 for each day the minibus is rented $0.8 per kilometre the minibus travels during the time it is rented This cost is reduced by n% if the minibus is a hybrid vehicle. The total cost of hiring 3 minibuses that are hybrid vehicles for 7 days is $10 584 Given that each minibus travels a total distance of 500 kilometres during these 7 days

Find the number of cars the company owns. The number of cars that are hybrid vehicles is the least value of N such that when N is divided by 120 the remainder is 7 and when N is divided by 504 the remainder is 7
Find the number of cars that are hybrid vehicles. The company owns 200 vans and minibuses in total. Each van and each minibus is either an electric vehicle or a hybrid vehicle. The ratio of the number of vans to the number of minibuses is 5 : 3 40% of the vans are hybrid vehicles. of the minibuses are hybrid vehicles.
Express the total number of vans and minibuses which are hybrid vehicles as a percentage of the total number of vans and minibuses. Show your working clearly.
A group of 90 students were asked if they own any of a dog (D), a cat (C) or a horse (H) Of these 90 students 4 own all three 14 own a dog and a cat 7 own a cat and a horse 26 own a dog only 2 own a horse only 6 own none of these animals Let x be the number of these students who own a cat only.
