If 6 apples cost 18 USD, how much do 9 of the same apples cost?
First, find the cost of one apple:
Cost per apple = 18 USD ÷ 6 apples = 3 USD/apple
Now, calculate the cost for 9 apples:
9 apples × 3 USD/apple = 27 USD.
How many pairs of legs do 10 cats and 5 people have?
Each cat has 4 legs. Therefore, 10 cats have:
10 cats × 4 legs/cat = 40 legs.
Each person has 2 legs. Therefore, 5 people have:
5 people × 2 legs/person = 10 legs.
Total legs = 40 (from cats) + 10 (from people) = 50 legs.
To find the number of pairs of legs, divide by 2:
50 legs ÷ 2= 25 pairs of legs.
If 5 books cost 35 USD, how much do 7 of the same books cost?
First, find the cost of one book:
Cost per book = 35 USD ÷ 5 books = 7 USD/book
Now, calculate the cost for 7 books:
7 books × 7 USD/book = 49 USD.
What number will continue the sequence: 2, 5, 10, 17, …?
The difference between the numbers in the sequence is increasing:
5 - 2 = 3
10 - 5 = 5
17 - 10 = 7
The differences are: 3, 5, 7. The next difference would be 9 (continuing the pattern of increasing by 2).
Therefore, the next number is: 17 + 9 = 26
What number continues the sequence: 2, 4, 8, 16, …?
The sequence is a pattern of doubling each number:
2 × 2 = 4
4 × 2 = 8
8 × 2 = 16
16 × 2 = 32
32 × 2 = 64
Thus, the next number in the sequence is 64.
