Explanation

5 percent *5

= (5/100)*5

= (5*5)/100

= 25/100 = 0.25

Explanation

The sum of odd integers from 1 to 100 are - 1 + 3 + 5 + 7 + ……… + 99.

This is an Arithmetic Progression with the following parameters: First Number, a = 1 Last Number, l = 99 Common Difference, d = 2 So, the Number of terms in the Arithmetic Progression, n = (l - a)/d + 1 = (99 - 1)/2 + 1 = 98/2 + 1 = 49 + 1 = 50 So, the sum of the Arithmetic Progression, S = n/2(l + a) = 50/2(99 + 1) = 25 X 100 = 2500 So, the sum of odd integers from 1 to 100 = 2500

Explanation

The rate at which Masons build walls is what we need to understand with this problem.

15*X = 20

15*X/20 = 1 Wall

Therefore, a fifteenth of a wall can be built by one mason in 20 days.

Each day, a mason can build 1/(15*20) or 1/300th of an entire wall.

Therefore, it would take one mason 300 days to build a wall on their own.

It would take 15 masons 20 days (300/20) to build a wall.

And we can estimate the 12 day solution with the following formula:

300/12 = 25

It would take 25 masons 12 days .

Explanation

Find the prime factorization of 70

70 = 2 × 5 × 7

Find the prime factorization of 80

80 = 2 × 2 × 2 × 2 × 5

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 2 × 2 × 2 × 5 × 7

LCM = 560

Explanation

From 6 → 9, we add 3.

From 9 → 12, we again add 3.

Following the same pattern:

12 + 3 = 15

Explanation

5 + 5 = 10 - 2 = 8

14 + 14 = 28 - 2 = 26

26 + 26 = 52 - 2 = 50

Explanation

357 + 357 = 714

468 + 468 = 936

If you know more details of this question, let us know please.

the correct answer would be 132. 7 x 11 = 77 7 x 12 = 84 11 x 11 = 121 11 x 12 = 132 ye b method hy i don't know which is correct. 

357/714= 468/x x =936 

Explanation

4+5+0+10+8+3=30/6
