Use rounding or compatible numbers to estimate the difference 762-332
Answers
Answer:
We have to use rounding or compatible numbers to estimate the difference of 762-332
Now rounding here can be done like rounding the tens place or the hundreds place and each will produce different result.
Rounding to tens place :
762=760
332=330
Difference =
Rounding to hundreds place :
762=800
332=300
Difference =

1.89 * 10^12 is a number written in scientific notation. To write a number in scientific notation, you write a number that is 1 or greater and less than 10, and then multiply it by 10 raised to an integer.
1.89 is the number from 1 to under 10.
12 is the integer exponent of 10.
The calculator writes 1.89 * 10^12, the number in scientific notation, as 1.89E12.
Again, 1.89 is the number from 1 to under 10, and 12 is the exponent. The E shows that the number after it is the exponent.
To write 1.89 * 10^-12, the calculator would write 1.89E-12.
The E stands for the exponent of 10 in scientific notation.

Let's first assume few variables!
x = Ishann's age (in years)
y = Christopher's age (in years)
1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)
2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)
Get the value of y from Equation (1) and plug it in Equation (2):
(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21
Hence Ishann is 21 years old!

Fiction books F, Non Fiction NF
F: NF = 11 : 1
Total ratio 11+ 1 = 12.
Fraction of Fiction books F, = 11/12
Total books = 312.
Fiction books = 11/12 * 312 = 286
Fiction books = 286

Answer:
3.1 = 3.10 because adding zero (0) in decimal number at the right most side doesn't affect the number as the same way adding zero at the left most side of a number doesn't affect the number.
Also, 3 and 1 ones are the same as 3 and 10 tenths.
That is why 3.1 = 3.10

Because you do -*-6v=positive 6v then -*-4w=positive 4w and then -*4=-4 and that takes care of the parenthesis
Basically you multiply the outside number or sign by all things inside the parenthesis
So in this problem you multiplied the negative sign by all the things inside the parenthesis
Final answer:
The distributive property is used to remove parentheses in a mathematical expression, by multiplying all terms within the parentheses by the term outside. In this case, -(-6v - 4w + 4) simplifies to 6v + 4w - 4.
Explanation:
Indeed, you're correct. Apparently, you use the distributive property to remove the parentheses in problems like this one: - (-6v - 4w + 4). The distributive property allows you to multiply each term inside the parentheses by the term outside the parentheses. In this case, you are multiplying by -1 because there is a negative sign before the parentheses. So the expression simplifies to 6v + 4w - 4.
