what is 159,095 rounded to the nearest hundred?
Answers
Answer:
159,100 is the answer
Step-by-step explanation:
159,100 is the answer because 159,095 is closest to 159,100 than 159,000. So therefore, 159,100 is the answer.
Answer:
159,100
Step-by-step explanation:
200,000 - rounded to the nearest hundred thousands
160,00 - rounded to the nearest ten thousands
159,00 - rounded to the nearest thousands
159,100 - rounded to the nearest hundreds
159,100 - rounded to nearest tens
159,095 - rounded to nearest ones
While rounding off to the nearest hundred, if the digit in the tens place is between 0 – 4 i.e. < 5, then the tens place is replaced by ‘0’.
If the digit in the units place is equal to or >5, then the tens place is replaced by ‘0’ and the hundreds place is increased by 1.

x−8.2=−9.09
What is the solution to the equation?
Enter your answer in the box.
Answers
Explanation: In order to solve for X we will need to do inverse operation and add 8.2 to -9.02 which would give us -0.89. You can always check if your answers correct by plugging your final answer in for X
The value of x in x−8.2=−9.09 is 0.89.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
x−8.2=−9.09
Now, we have to solve for x
Add 8.2 on both side
x-8.2 + 8.2 = -9.09 + 8.2
x= 0.89
hence. the value of x is 0.89.

What are Mixed Numbers?
A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
[tex]\frac{p}{1\frac{3}{7} } = -10.2[/tex]
To solve for p ,
Multiply by [tex]1\frac{3}{7}[/tex] on both sides we get ,
p = [tex]-10.2[/tex] × [tex]1\frac{3}{7}[/tex]
Now , [tex]1\frac{3}{7}[/tex] can be written as the improper fraction form as [tex]\frac{10}{7}[/tex]
So ,
p = [tex]-10.2[/tex] × [tex]\frac{10}{7}[/tex]
p = [tex]\frac{-102}{7}[/tex]
Now , the improper fraction [tex]\frac{-102}{7}[/tex] can be represented by the mixed number as [tex]-14 \frac{4}{7}[/tex]
Hence , The mixed number is [tex]-14 \frac{4}{7}[/tex]
