### What math symbol placed between 4 and 7 that give a number greater than 4 and less than 7?

Let n be the number between 4 and 7 then the required expression is written:- 4 < n < 7 The symbol used is a "less than" symbol and the expression is 4 is less than n which is less than 7. When the arrowhead points to the right > then this is called a "greater than" symbol and we could put n > 4 and 7 > n.

### How many integers n greater than and less than 100 are there such that if the digits of n are reversed the resulting integer is n plus 9?

I'm assuming the question should read n greater than 10 and less than 100 and there are 8 numbers that satisfy this, 12 23 34 45 56 67 78 89 So the answer is d http://www.webanswers.com/share-question.cfm?q=how-many-integers-n-greater-than-and-less-than-100-are-there-such-that-if-the-digits-of-n-are-the-is-1379ff | http://www.webanswers.com/answer/1566078/education/how-many-integers-n-greater-than-and-less-than-100-are-there-such-that-if-the-digits-of-n-are-the-is-1379ff | http://www.webanswers.com/report-abuse.cfm?q=how-many-integers-n-greater-than-and-less-than-100-are-there-such-that-if-the-digits-of-n-are-the-is-1379ff&p=1566078

### What is the sum of all prime numbers between 1 and 100 that are simultaneously one greater than a multiple of 4 and one less than a multiple of 5?

118 Start with the numbers that are 1 less than a multiple of 5. This produces, 4, 9, 14, 19, 24,...,89, 94, 99 Clearly the sequence 4, 14, 24 etc has to be a multiple of 4 or 2 greater than a multiple of 4 so these do not apply. This leaves 9,19,29,39,49,59,69,79,89,99. The prime numbers within this group are, 19, 29, 59, 79 & 89. The numbers that are 1 greater than a multiple…

### Write a simple program algorithms flow charts to find out how many of the numbers from 1 to 10 is greater than 4?

/* c program for how many of the numbers from 1 to 10 is greater than 4? */ #include<stdio.h> void main() { int i ,j=0; /* j is used for counting the nos greater than 4 from 1 to 10*/ for(i=1;i<=10;i++) if(i>4) j++; printf("\n The numbers greater than 4 , from 1 to 10 is %d",j); } Algorithm step 1:start step 2 :initialize j=0 step 3 :Initialize i=1,check whether i < 10 ,if true increment…

### Why are decimal numbers not integers?

For simplicity I will assume you're working in base x, for any integer x greater than 1, although the argument extends to integers greater than 1 in absolute value (note that in base -1,1 all decimal numbers are in fact integers and that in base 0 decimals are not very well defined). In base x, x can of course be conveniently denoted as 10, so in the remainder of this answer I will work in…
