A. $0.99
Step-by-step explanation:
The unit rate will be the amount associated with 1 unit: $0.99.
Step-by-step explanation:
<h3>Given,</h3>
perimeter - 16cm
length - 5cm
find breadth,
perimeter of rectangle = l × b
16cm = 5 × b
b = 16/5
b = 3.2 cm
Answer:
8
Step-by-step explanation:
Since we are adding small numbers we can use our hands to solve it.
1) We can use one hand to represent the value of 5
2)We use the other hand and lift tree fingers up.
3)counting the fingers will give you a total of 8
