Answer:
Barbara’s equation did not consider the number of bottles of iced tea.
Explanation:
She made this error because she included 1.25 with the x variable but did not include the x variable next to 1.49.
The x variable is important because it can keep track of how many bottles were sold of each water and tea.
So, this means <u>Barbara’s equation did not consider the number of bottles of iced tea.</u>
The real equations should be 1.25x + 1.49x = 100

In the late 1800s, people in many parts of the world decided to leave their homes and immigrate to the United States. Fleeing crop failure, land and job shortages, rising taxes, and famine, many came to the U. S. because it was perceived as the land of economic opportunity.

Answer:
sinF = 3
/5 or 0.6.
Explanation:
Triangle ABC is a right triangle with its right angle at B. Therefore, AC is the hypotenuse of right triangle ABC, and AB and BC are the legs of right triangle ABC. According to the Pythagorean theorem,
AB=√202−162=√400−256=√144=12
Since triangle DEF is similar to triangle ABC, with vertex F corresponding to vertex C, the measure of angle∠F equals the measure of angle∠C. Therefore, sinF=sinC. From the side lengths of triangle ABC,
sinF = oppositeside
/hypotenuse = AB
/AC = 12/
20 = 3
/5
