Answer: "A sporting goods store sold 2.5 times as many footballs
as basketballs last year."
Step-by-step explanation:
We can model the problem using a right angle triangle.
The two sides, AB and BC are equal
By Pythagoras, we find the length of AC =
=
Using the sin ratio ⇒ sin θ = opposite/hypotenuse, we have
Using the cos ratio ⇒ cos θ = adjective/hypotenuse, we have
Using the tan ratio ⇒ tan θ = opposite/adjective, we have
13. Minus 4
14. Minus 200
15. Minus 30
It illustrates distributive property
The easiest approach is to multiply a number in decimal format by 100. Move the decimal: Another way to convert from decimal to percentage format is to move the decimal two places to the right.
