Step-by-step explanation:
30°, 60°, 90° triangle theorem states that:
Lengths of the side opposite to 60° angle is equal to root 3 upon two times of the length of hypotenuse and side opposite to 30° angle is equal to 1 upon two times of the length of hypotenuse.
Mathematically it can be expressed as:
<u>Given</u>:
Given that the graph of Bill's Boffo Bagel.
We need to determine the unit rate for Bill's Boffo Bagel.
<u>Unit rate:</u>
The unit rate can be determined using the formula,
Let us substitute any two coordinates that the line passes through the points in the graph.
Substituting the coordinates (2,7) and (4,14) in the above formula, we get;
Simplifying, we get;
Therefore, the unit rate for Bill's Boffo Bagel is $3.5.
Hence, the unit rate is $3.50 for 1 bagel.
Thus, Option b is the correct answer.
