15.
6 pachages
each pcage has 30
6*30=180 total
17 left over
how many used
used=total-left over
used=180-17
used=163
16. xy is 2 digit number
multiplules of 10 (whole multipules) always end with 0 so y=0
and has 3 as one of its factors
factors of 3 is 3,6,9,12
30,60,90 is answer
17.
30 in 9 parks
30 times 9
30=10 times 3
3*10*9
group the 3 and 9
10*(3*9)
3*9=27
10*(27)
270
15. 163
16. 30,60,90
17. see above, 270
83 percent.
Simply do 11-6, which is 5; then do 5/6, and multiply by 100 to get the percent. That equals out to be 83.3333 percent. Or 83 percent when rounding.
Modelling can be done by Graph Data Modelling
Step-by-step explanation:
1.Graph data modeling is the process in which a user describes an arbitrary domain as a connected graph of nodes and relationships with properties and labels.
2.The following tasks are performed in an iterative manner:
Identify entity types.
Identify attributes.
Apply naming conventions.
Identify relationships.
Apply data model patterns.
Assign keys.
Normalize to reduce data redundancy.
Denormalize to improve performance.
3.One such approach is the property graph model, where data is organized as nodes, relationships, and properties (data stored on the nodes or relationships). ... Nodes are the entities in the graph. They can hold any number of attributes (key-value pairs) called properties
