Eric's notebook has 30 pages. He wants to write a number on each page. How many digits will he write when he numbers all the pages in the notebook?

Answers

Answer 1

Answer:
i think it would be ... 60 because 30 times 2 = 60 and on each page there are 2 pages the one in the front and the one in the back .... I hoped i gaved u the right answer

Answer 2

Answer: when you number something it depends wethor or not you are using 0 as a place holder (01 02 03 ect.) if so the answer would be 60 because all you have to do is multiply by two. If you are not using place holders the answer would be 59 because 30*2=60-9 you take away 9 beace there were nine place holders (Zero)

What is the system of linear equations?

A system of linear equations is a collection of one or more linear equations involving the same variables.

Given that, a teacher purchased a total of 460 notebooks and pencils. Each notebook cost $1.75 and each pencil cost $0.05. If the teacher spent a total of $218.50, we need to find the number of notebooks the teacher purchased,

We will use the concept of system of linear equations to solve this,

Let the number of notebooks be n and that of pencils be p,

n + p = 460

p = 460-n....(i)

1.75n + 0.05p = 218.50...(ii)

Using equation (i) in eq(ii)

1.75n + 0.05(460-n) = 218.50

1.75n + 23-0.05n = 218.50

1.7n = 195.5

n = 115

Hence, the number of notebooks the teacher purchased, is 115

Which one is greater 0.6 or 0.60

Answers

They are the same, because there's an invisible 0 next to 0.6.....

.6 and .60 are equal in the same way that 60 and 060 are equal -- The 0 is useless. More mathematically, .6 = six tenths or 6/10 and .60 = sixty hundredths or 60/100 and 6/10 is just a simplified version of 60/100.
