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?

Answers

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

Look at the two equations: -3x + 6 = 21 -3x + 6 < 21 Which statement best describes the process used to solve the equations? In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality. In both cases, divide by –3 on both sides, but reverse the inequality sign when doing that for the inequality. The process is exactly the same for solving the equation and solving the inequality. The process for solving the equation is entirely different from solving the inequality.

Which of the following tools did the Greeks limit themselves to in their formal
geometric constructions?
Check all that apply.
O A. Straightedge
O B. Compass
C. Ruler
D. Tracing paper

Answers

It should be B because they didn’t have all that stuff at the time and people would just use compass

The tools that Greeks limit themselves to in their formal geometric constructions are straight edge and compass. Therefore, A and B are the correct answers.

What are geometric constructions?

Geometric construction is the process of drawing a geometrical figure using two geometrical instruments, a compass, and a ruler.

Compass and straight edge were the tools that were used by Greeks in their formal geometric construction.

During earlier Greek times, simple geometric tools were used like compass and straight edge to draw something. Rulers and other tools came to use much later in time.

Therefore, A and B are the correct answers.

if 30 houses cost 1.7 billion, how much money will 300 houses cost?

Answers

Answer:

17 billion cause 30*10 300

Answer:

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
