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! :)

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

Mike and Andy are each reading the same book. Mike read 2/4 of the book on Tuesday and 1/3 of the book on Wednesday. Andy read 1/2 of the book on Tuesday and 1/5 of the book on Wednesday. Andy says that altogether he read more of the book on Tuesday and Wednesday than Mike. Is Andy correct?


Select from the drop-down list to complete the sentence. Explain your answer by typing in the box.


is andy correct or incorrect




Explanation:
ASAP

Answers

Andy is wrong, on tuesday they read the same amount, but on wednesday mike read more than andy because 1/3>1/5 so mike read more altogether, hope this helps :) plz give branliest if it does

In the second attempt, Mike read (1/3)rd of the book which is more than

(1/5)th of the book Andy read.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given,  Mike read 2/4 of the book on Tuesday and 1/3 of the book on Wednesday.

Therefore in total, Mike read (2/4 + 1/3) of the book.

= (6 + 4)/12.

= 10/12.

= 5/6 of the book.

Also given, Andy read 1/2 of the book on Tuesday and 1/5 of the book on Wednesday.

Therefore in total, Andy read (1/2 + 1/5) of the book.

= (5 + 2)/10.

= 7/10.

As the fractions (2/4) which Mike read and (1/2) Andy read they have read the same amount of the book but in the next time Mike read 1/3 of the book and 1/5 and we know 1/3 is greater than 1/5.

So, Mike read more of the book than Andy.

Mr. Sonny's science class is calculating the average number of blinks per minute. Jan blinks 126 times in 7 minutes. What is her blinking rate, in blinks per minute?

Answers

18 blinks per min since 126 divided by 7 equals 18
Answer:
b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.
