Answer:
To convert scientific notation to standard form you would need to move the decimal point over the number of the places that the exponent indicates. If the exponent is negative you move the decimal to the left, and if the exponent is positive you move the decimal to the right.
Step-by-step explanation:
1.456*10^3 would be scientific notation.
The exponent is a positive 3, means that you move the decimal 3 places to the right.
1456 would be the standard form.
1.456*10^-3 would be scientific notation.
The exponent is a negative 3, means that you move the decimal 3 places to the left.
0.001456 would be the standard form.

If m is a positive integer, what is the least value of m for which 225 is a factor of 120m? Please explain your answer
OPTIONS:
A) 3
B) 5
C) 15
D) 25
E) 30
The least value of the variable 'm' will be 15. Then the correct option is C.
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.

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

Answer:
1= 1 7/36
2= 1/2
Step-by-step explanation:
1.) 7/9+5/12
find the LCM of 9 and 12
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
1 7/36
2.) 21/24 - 3/8
find LCM of 24 and 8
LCM = 24
(21/24 x 1/1)+ (3/8 x 3/3)
21/24 + 9/24
30/24
Divide 30 by 24 to make it mixed fraction
= 1 6/24

GIVING BRAINLIEST Katie and Mina both commute to work. Katie's commute on the train takes 10 minutes more than one half as many minutes as Mina's commute by car. 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
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
