natali 33 [55]

Answer:

Step-by-step explanation:

I know the answer is 26 miles but I cannot figure out how they came up with that answer using the distance formula.It looks like you need to find the shortest distance (as the crow flies) between the home and the office.

Use the Pythagorean Theorem.

6^2 + 10^2 = c^2

136 = c^2

11.67 = c

4^2 + 14^2 = c^2

212 = c^2

14.56 = c

11.67 + 14.56 = 26.2 = 26 miles

Help me please. The answer is 3350 but i need to do step by step. But i dont know how<br>​
Radda [10]

Answer:

3350

Step-by-step explanation:

100 + 8 = 108%

108% is 3618

100% is x

108x = 3618 * 100

108x = 361800

x = 361800/108

= 3350

Hence, the original salary is HRK 3350
