Find the nearest place value. Use #13 to do #14
kondaur [170]
When rounding here are the rules
If the next number to the right is 1-4, you will round down or keep the # the same.
If the next number to the right is 5-9, you will round up to the next number.

So with your # 281,421,906
a. hundred million.  This is the first 2...the number to the right of it is 8, so we will round the 2 up.  And the answer is 300,000,000
b. ten million.  This is the 8...the number to the right of it is 1, so we will round it down and 8 will remain an 8.  And the answer is 280,000,000
c. million.  This is the first 1 (281)...the number to the right is 4, so we will round down and 1 will remain a 1.  And the answer is 281,000,000
d. hundred thousand.  This is the 4...the number to the right of it is 2, so we will round down and the 4 will remain a 4.  And the answer is 281,400,000
e. thousand.  This is the second 1 (281,421)...the number to the right is the 9, so we will round up and the 1 will become a 2.  And the answer is 281,422,000

Now for #14, think about the rules.
  1. If you round it to the nearest one, you get 7.  
  2. If you round it to the nearest tenth, you get 7.0.
  3.  If you round it o the nearest hundredth, you get 7.00
  4.  It is the least number that fits the clues.

Ok basically it is saying, it rounds up to 7.  So what would be the number that would round UP to 7?  That would be 6.  I'm rounding UP because it says it is the LEAST number that fits the clues.

translate this into an expression: the quotient of a number, x, and 8, could you please explain it to me?​
Xelga [282]

Answer:

x/8

Step-by-step explanation:

First, we are given "the quotient of...". This means that we are dividing something/something else. If two numbers are given in the phrase "something and something else", the first number given will be the something, and the second number will be the something else.

The first number listed is x. Therefore, we have

x/something else.

Next, we are given "and 8", so we have x/8 as our expression

Answer:

29

Step-by-step explanation:

f(x)=8(x−3)+13
