The first and third are correct. They are equal.

The second is incorrect. This is because 1800 meters = 1.8 km (not 18 km). The answer you should have is a "less than sign" because 1.8 km is smaller than 18 km.

To go from meters to kilometers, you move the decimal point 3 spots to the left. This is the same as dividing by 1000.

To go from kilometers to meters, you move the decimal point 3 spots to the right. This is the same as multiplying by 1000.

Plot the two decimals on the number line below 0.43, 0.39. Write an inequality comparing the two decimals. Explain your answer u
Ilya [14]

Answer:

See the image below.

Step-by-step explanation:

The decimals 0.43 and 0.39 are equivalent to  43/100 and 39/100. These decimals lie between 0 and 1.

Draw a number line, mark off and label the multiples of 0.10(e.g 0.10, 0.20) in the interval 0-1.  

Mark 0.43 between 0.4 and 0.5, a little closer to 0.4.

Mark 0.39 between 0.3 and 0.4, just behind 0.4.

Since 0.39 is smaller than 0.43( 0.39 lies on the left to 0.43), the inequality is:

              0.39<0.43

In 4 hours if you count the miles by the road linking the 2 buses. This is because 55 for one bus and 45 for the other bus added together equals 100 miles/hour. Therefore, 4 hours will be the time the 2 buses are 400 miles apart.

What's the answer for (2+i)(i+2i)?​
slava [35]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{3 {i}^{2}  + 6i}}}}}

Step-by-step explanation:

\sf{(2 + i)(i + 2i)}

Use the distribute property to multiply each term of the first binomial by each term of the second binomial.

⇒\sf{2(i + 2i) + i(i + 2i)}

⇒\sf{2i + 4i +  {i}^{2}  + 2 {i}^{2} }

Collect like terms

⇒\sf{3 {i}^{2}  + 6i}

Hope I helped!

Best regards!
