Answer:
∠ A = 50°
Step-by-step explanation:
The angle adjacent to 145° inside the triangle is
180° - 145° = 35°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
85° is an exterior angle of the triangle , then
∠ A + 35° = 85 ( subtract 35° from both sides )
∠ A = 50°
Cost/(number of cassettes) = $14.50/2 = x/15
Multiply by 15 to solve
15*($14.50/2) = x = $108.75
15 cassettes will cost $108.75.

Answer:
<em>35 words per minute. </em>
Step-by-step explanation:
To find the answer you have to divide <em>Minutes</em> by <em>Words Typed</em>.
105 ÷ 3 = 35.
175 ÷ 5 = 35.
315 ÷ 9 = 35.
<em>Therefore, our answer is 35.</em>
A formula models
real-world phenomena when it describes the relationship between the variables of
a real life situation. We use formulas in our every day life, but maybe are not aware of it. Some examples of using math formulas in the real world are: - the most obvious example is that we use formulas in the grocery store (multiplication, estimation, percentages,...
- we use formulas while baking (measuring ingredients, understanding ratios and proportions,<span> converting metrics,...)</span>
