Bill's rectangular bedroom is 2 m long, 4 m wide, and 2.5 m high. Air typically has around 4,000 bacteria per cubic meter. About how many bacteria are present in Bill's bedroom?
Answer:
80000bacterias
Step-by-step explanation:
Volume of the bedroom= length ×width× height
Given
Length = 2m
Width = 4m
Height= 2.5m
Volume of the bedroom= 2×4×2.5
Volume of the bedroom = 20m³
Given that;
4000bacterias = 1m³
x bacteria = 20m³
Cross multiply
x =4000×20
x =80000
Hence 80000 bacteria's are present in Bill's room

If 30 houses cost 1.7 billion, 300 houses cost 17 billion
Step-by-step explanation:
If you were to make it an equation you would make it
30 = 1.7
Now we were told the 30 would be made 300 so its obvious you multiplied by 10 and whatever you did to one side you do to the other so its
30 x 10 = 1.7 x 10 is 300 = 17
your answer is 17 billion

Have a great day y'all :)
(–4 + i) + 4i = –4 + (i + 4i) is the associative property of addition. Thus, option A is correct.
What is the associative property of addition?According to the associative property of additionally, whenever at least three figures are added together, the outcome is unaffected by the sequence in which the individual numbers are added.
In the first given condition is is stated:
(–4 + i) + 4i = –4 + (i + 4i)
-4 + i + 4i = -4 + i + 4i
5i - 4 = 5i - 4
As the LHS = RHS, the property is said to be valid for the associative property of addition.
Therefore, option A is the correct option.
