Find the smallest number that divides by 44 55 and 220 leaving remainder 5
galina1969 [7]
The numbers from which we are to determine the smallest number that can be divided leaving a remainder of 5 are 44, 55, and 220. We have to do the prime factorization of all the numbers to determine their least common multiple (LCM).

Factorization of 44:
   44 = 11 x 4 = 11 x 2 x 2

Factorization of 55:
  55 = 11 x 5

Factorization of 220:
  220 = 11 x 20 = 11 x 5 x 4

Since 220 has all the factors from 55 and 44 then, the least common multiple is 220. Add 5 to the LCM in order to determine the unknown.

5.Find the slope of a line perpendicular to
Lemur [1.5K]
Hi there!

When the slopes of two perpendicular lines are multiplied the outcome will be -1.

The slope is the number that is positioned in front of the variable x in the formula. In this case the slope of the given line is -2/5.

Let's call the slope of the perpendicular line m and take into account the given data of the question and my earlier explanation. We then find the following:

-  \frac{2}{5}  \times m =  - 1
Divide both sides by - 2/5.

m =   \frac{ - 1}{  - \frac{2}{5} }  = 2 \frac{1}{2}  =   \frac{5}{2}
The answer is B.

~ Hope this helps you!
