The area of the quadrilateral is 60
Actually the formula for the area of a triangle is A = 1/2bh.
First step: multiply both sides by 2, to get rid of the 1/2.
2A = bh
Now divide both sides by b.
2A/b = h or h = 2A/b
d = |150 - 20t|
70 = |150 = 20t|
70 = 150 - 20t -70 = 150 - 20t
-80 = -20t -220 = -20t
4 = t 11 = t
Answer: 4, 11 seconds
Answer:
1,800 vehicles
Step-by-step explanation:
We need to find what fraction of an hour 10 seconds is, so we will divide 60 (minutes) by 1/6 (minutes). From solving this, we will get 360. That is how many 10 second chunks pass in an hour. We will multiply 360 by 5, and we get 1,800 vehicles!
15+15+15=45 Hope this helps.
