Answer: The probability is 2/5.
Step-by-step explanation: If there are 5 pink bows, 1 blue bow, and 4 purple bows, there are a total of 10 bows in the box. The probability of choosing a purple one is 4/10 (since there are 4 purple bows). 4/10 simplifies to 2/5.
The answer is 0.1538461538 but you round it to the nearest tenth that gives you 0.2
Among many other formulas, the area of a triangle is

where B is the angle between sides a and c.

Answer: 92.05 sq cm, first choice
Bonus. Here's a formula for the area S of a triangle your teacher doesn't know:

-15 both sides and then it’s will be
5x = 13 then u divide both sides over 5 and the answer will be ( X=2.6 )
8000 x .60 = $48.00
This is because 4 tons = 8000 pounds.
