Step-by-step explanation:
You have to add 2.8t plus 5.7t together
slope=1
y-intercept= -1
y=x-1
<h3>Your Answer is y=x-1</h3>
Using proportions, it is found that 66 people in the survey worked on election day.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For this problem, the amounts of people who worked are:
Hence the total amount is given by:
0.64 x 50 + 0.4 x 85 = 66.
66 people in the survey worked on election day.

<u>Answer-</u>
<em>The height of the traffic light is 21.8 feet.</em>
<u>Solution-</u>
As shown in figure, we can see the right triangle formed from the situation,
From the question,
BC = the distance walked by Andrew from the traffic light = 20 feet
Height of Andrew's eye = 5 feet
Height of the traffic light = AB + Height of Andrew's eye
From the properties of triangle,
Therefore, height of the traffic light = AB + Height of Andrew's eye = 16.8+5 = 21.8 feet
