Answer:
4:5
Step-by-step explanation:
since there are 4 oranges bought for every 5 apples, the ratio of oranges to apples sold is 4:5
Ok, so what we want to do here is first remove the repeating decimal.
x=2.16 repeating
10x=21.6 repeating
100x=216.6 repeating
Subtract 10x=21.6 repeating from 100x=216.6 repeating. This will get rid of the repeating numbers.
100x=216.6 repeating
-10x=21.6 repeating

90x=195
Divide both sides by 90.
x=195/90
Now you can simplify that into 13/6.
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
