Answer:
The length of side AB is 5 units
Step-by-step explanation:
* Lets revise how to find the distance between two points
- If there are two points their coordinates are (x1 , y1) and (x2 , y2),
then we can find the distance between them by this rule:
d = √[(x2 - x1)² + (y2 - y1)²]
- Now lets solve the problem
∵ A = (4 , -5)
∵ B = (7 , -9)
- To find the length of AB use the rule of the distance above
- Let point A is (x1 , y1) and point B is (x2 , y2)
∵ x1 = 4 and x2 = 7
∵ y1 = -5 and y2 = -9
∴ AB = √[(7 - 4)² + (-9 - -5)²]
∴ AB = √[(3)² + (-4)²]
∴ AB = √[9 + 16] = √25 = 5
* The length of side AB is 5 units
Answer:
the answer is 12
Step-by-step explanation:
Answer:
No, natural numbers are positive whole numbers.
So, numbers such as 1, 10, 100, 1000 etc.
Numbers that cannot be a type of natural number is decimals like 3.5, or negative numbers.
Answer:
7times 6<9 times 5
Step-by-step explanation:
7 times 6 is 42 and 9 times 5 is 45 so nine times five is larger
Answer:
99 dandelions
Step-by-step explanation:
Given: ratio of dandelions to peonies in the garden was 11 to 4
Total number of peonies in the garden = 36
To find: Total number of dandelions in the garden
Solution:
A ratio indicates number of times one quantity contains another quantity.
So,
99 dandelions were there in the garden.
