Answer:
? What M? What is impossible?
Yes, she is correct
1/2 + 1/2 = 1 or 0.5 + 0.5 = 1 so half of a wall plus half of a wall equals one hole wall.
That's as simple as I can put it mathematical reasoning. I hope this helps
2x3=6
3x2=6
6 divided by 2=3
6 divided by 3=2
Answer:
In 29 1/2 days, the total pipe laid is 
mile.
Step-by-step explanation:
The length of pipe laid in 1 day = 1/8 mile
So, the length of pipe laid in half day = half of (1/8 mile)
= 
Now, 29 1/2 days on simplification means 29 and half day.
So, length of pipe in 29 days = 
mile
Now adding the length laid in half day = 
So, in 29 1/2 days, the total pipe laid is mile.
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
