0.71 dollars = 1 franc
1 dollar = 1/0.71 francs = 1.41 francs
Answer:
1 and 9
Step-by-step explanation:
By the Triangle Inequality Theorem, the sum of two side lengths of a triangle is always greater than the length of the third side.
In other words, in a triangle with side lengths and we always have
Applying this to this question, the other side length, must satisfy the following inequalities:
Solving these inequalities gives
Combining these solutions, we have Therefore, the length of the third side falls between 1 and 9.
(A.675 divided by 1600), and (B.675/1600) are the answers
You can solve with the formula for cuadratic equations:
x=−b±√b2−4ac
2a
-2+b<3
⇒ b< 3-(-2)
⇒ b< 3+2
⇒ b<5
The final answer is b<5.
Hope this helps~
