alan is converting large and small numbers from standard notation to scientific notation. group the numbers according to their powers of 10

Answers

Answer:

i am kind of confused by the question but i would say to but all the numbers below 1 in the 10^-4 section and the numbers above 1 in the 10^6.

i might be wrong i don't what the question is really.

Step-by-step explanation:

Alan is converting large and small numbers from standard notation to scientific notation

10⁶  = 4.03 x 10⁶, 2.93 x  10⁶, 5 x  10⁶

10⁻⁴ = 1.2x 10⁻⁴, 6 x 10⁻⁴,  5.9 x 10⁻⁴

What is the scientific notation of a number?

The standard form for a number is a method by which we write number in a format like b×10ˣ. The value of b should be in between 0 to 10.

Given that,

The numbers,

0.00012, 4030000, 2930000, 0.0006, 5000000, 0.00059

Taking number, 0.00012

To convert it into scientific notation,

It should be in from of  b×10ˣ,

So, now dividing and multiplying 10000 into the number 0.00012,

⇒  0.00012 x (10000/10000)

⇒  (0.00012 x 10000)/10000

⇒   1.2/10000

⇒   1.2x 10⁻⁴

Similarly,

0.0006 can be written as 6 x 10⁻⁴

And  0.00059 can be written as 5.9 x 10⁻⁴

Now taking number, 4030000

To convert it into scientific notation,

It should be in from of  b×10ˣ,

So, now dividing and multiplying 1000000 into the number 4030000,

⇒ 4030000 x (1000000/1000000)

⇒  (4030000 / 1000000) x 1000000

⇒   4.03  x 1000000

⇒   4.03 x 10⁶

Similarly,

2930000 can be written as 2.93 x  10⁶

And 5000000 can be written as 5 x  10⁶

Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.

Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?

350 m/s

355 m/s

360 m/s

365 m/s

Answers

Answer:360 m/s

Step-by-step explanation:

The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

As we can see in the graph:

When the air temperature is 10°C the speed of sound is around 337m/s

When the air temperature is 20°C the speed of sound is around 344m/s

When the air temperature is 30°C the speed of sound is around 348m/s

When the air temperature is 40°C the speed of sound is around 355m/s

From the above observation, the air temperature increases the speed of the sound increases.

So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.

Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.

Answers

Answer:

B

Step-by-step explanation:

Its B because you distribute each term inside the parenthesis by the number out side

4×2x= 8x

4×3= 12

Get rid of the parenthesis after distributing

which makes 8x+12

Answer:

B. 8x + 12

Step-by-step explanation:

First you'd start with the parentheses because of PEDMAS. But because you can't do anything in there, you go to multiplying 4 by each item inside the parentheses. 4x2x gives 8x. 4x3 gives 12. Leaving you with 8x+12. Hope that helps! :)

Rosemary is driving to Chicago, and she is 84 miles away. She wants to arrive in 1.5 hours. What rate of speed will she have to maintain to arrive in that time?
Group of answer choices

Rosemary needs to maintain 126 mph.

Rosemary needs to maintain 65 mph.

Rosemary needs to maintain 56 mph.

Answers

Answer:

56 mph

Step-by-step explanation:

Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84

Answer:

56

Step-by-step explanation:

84 / 1.5 = 56
