Answer: set up the relation as a table or ordered pairs
Step-by-step explanation: the domain has to be matched with exactly one element in the range.
question 9
a) 2 x 3 = 6m^2
b) diameter = 2m and radius = 1m
c) πr^2 is the equation, so 3.14 x 1^2 = 3.14m^2
and the semi circle is half of that, 1.57m^2
d) 6 + 1.57 = 7.57m^7
question 10
30 x 70 = 2,100m^2
πr^2 so 3.14 x 15^2 = 706.5m^2
2,100 + 706.5 = 2,806.5m^2
i hope this is correct :D
Answer:8.4 or 8 depends on the rounding
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Answer:
Other number is 23
Step-by-step explanation:
Let the two numbers be x and y.
We have given that average of x and y is 17.
i.e 
if one of the number is 11,
Then , 
or (11 + y)/2 = 17
or 11 + y = 34
or y = 34 - 11
or y = 23
