Answer 1

Answer:Concept Development: We have learned why scientific notation is indispensable in science. This means that we have to

learn how to compute and compare numbers in scientific notation. We have already done some computations, so we

are ready to take a closer look at comparing the size of different numbers.

Step-by-step explanation:There is a general principle that underlies the comparison of two numbers in scientific notation: Reduce everything

to whole numbers if possible. To this end, we recall two basic facts.

1. Inequality (A): Let and be numbers and let > . Then < if and only if < .

2. Comparison of whole numbers:

a. If two whole numbers have different numbers of digits, then the one with more digits is greater.

b. Suppose two whole numbers and have the same number of digits and, moreover, they agree digitby-digit (starting from the left) until the

th place. If the digit of in the ( + )

th place is greater than

the corresponding digit in , then > .

LCM= 36

(7/9 x 4/4) + (5/12 x 3/3)

28/36+15/36

= 43/36

Divide 43 by 36 to make it a mixed fraction

Explain how you would use fraction bars to find the quotient of 10/12Divided by 4/6 what is the quotient

Answers

Answer:

11/4

Step-by-step explanation:

Draw one whole fraction bar. Next, draw 6 equal bars under it, since you are dividing by sixths. Then draw a twelfths fraction bar with 2 twelfths for each sixth bar. Above the twelfths bar, circle groups of 4 sixths. There is one group of 4/6 with 1/6 remaining. Since 1/6 is 1/4 of 4/6, the quotient is 1 1/4.

Answers

Answer: 2.750

Step-by-step explanation: make 12 7/8 into a decimal then subtract 0.75 to 12.875 than you have 12.125 now you subtract 9. 375 to 12.125 and you have your answer I hope this is right

The answer is 2 6/8

Work-
1. Turn .75 into a fraction which is 3/4.
2. Then change the denominator to be common with the other which would make it 6/8.
3. Then make 12 7/8 into a improper fraction which is 103/8 and subtract the 6/8 to get 97/8.
4. Then change 9 3/8 into an improper fraction which is 75/8.
5. Subtract 75/8 from 97/8 to get 22/8.
6. Lastly, change it to a mixed number which would come out to be 2 6/8.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

If m is a positive integer. And the least value of m for which 225 is a factor of 120m.

Then the factor of the number 225 will be given as,

225 = 3 x 3 x 5 x 5

Then the factor of the number 120m will be given as,

120m = 2 x 2 x 2 x 3 x 5 x m

The least value of 'm' will be given as,

⇒ 3 x 5

⇒ 15

The least value of the variable 'm' will be 15. Then the correct option is C.

It takes Katie 30 minutes to get to work. Write an equation to determine how many minutes it takes Mina to get to work. 30 = one halfx + 10 30 = one halfx − 10 30 = 2x − 10 30 = 2x + 10

Answers

Answer:

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4

Simplifying

x = 4
