Yes, segments 9, 9, and 1 can form a triangle. The rule that determines this is called the Triangle Inequality Theorem. This states that for a triangle with side lengths A B and C to exist, the following relationships have to apply: A + B > C B + C > A A + C > B With side lengths 9, 9, 1, this rule applies. 9 + 9 > 1 9 + 1 > 9 1 + 9 > 9 Therefore, a triangle will be able to be formed from the side lengths.
Let cost price be x according to question x + 40% of x = 280 x+ 0.4x=280 1.4x=280 x=200 this 200 is the store cost or cost price for store 30%of 200= 60 according to question, cost for employee= 200-60= 140
