The value 9 because you add
<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
Perimeter = 2(width) + 2(length)
w = 5x
l = x + 5
P = 2(5x) + 2(x + 5)
P = 10x + 2x + 10
P = 12x + 10
Answer:
37 gallons
Step-by-step explanation:
To find the mileage you need to divide the distance by the amount of fuel:
24 ÷ 2 = 12 mpg
To find the amount of fuel needed you divide the distance by the mileage:
444 ÷ 12 = 37 gallons
