How many of the 1000 smallest positive integers are congruent to 1 modulo 9?
Serjik [45]
1 modulo 9 is the set of numbers as follows:

(0(9) + 1), (1(9) + 1, ....)
which is:
1, 10, 19

All we have to do is divide 1000 by 9, and round down.

1000/9 = 111.111......
There are 111 numbers.
Now let us check our work.

the set is as follows:

(1,10,19, ....... (111)9 +1)
(1, 10, 19 ........ 1000)
We are within 1000.
Therefore, 111 of the 1000 smallest positive integers are congruent to 1 modulo 9.

What is the value of b? IT 3b b+52 Н G j b =
cluponka [151]

b=26

Explanation

Step 1

we have two equals triangles, because

\begin{gathered} HG=GJ \\ \text{and} \\ GI\text{ is a common side for both triangles} \end{gathered}

then, the hypotenuses are equal

3b=b+52

"is step 1 clear?

Step 2

solve the equation

\begin{gathered} 3b=b+52 \\ \text{subtract b in both sides} \\ 3b-b=b+52-b \\ 2b=52 \\ \text{divide both sides by 2} \\ \frac{2b}{2}=\frac{52}{2} \\ b=26 \end{gathered}
