How many integers are there between 9 and 100, including 9 and 100?

91 Integers

Step-by-step explanation:

Integers are whole numbers that can either be positive, negative, or zero.

Example would be counting numbers

Basically 100-9=91

so there's 91 integers including 9&100

92 integers

Step-by-step explanation:

You may think 100-91=9 is correct. But because 9 and 100 are included, you have to add 1 to the answer. However, you don't add 2 since 0 is not included into the integers between 1 and 100.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
