Two find the area of a triangle multiply the two sides together and then divide by 2. To find the area of a rectangle just multiply the two sides that are given and you will get the answer.
Answer: at 50 mph, she drove for 4 hours.
at 45 mph, she drove for 2 hours.
Step-by-step explanation:
Let t represent the time that she spent driving at 50 miles per hour.
Taylor took 6 hours to drive home from college for Thanksgiving break. This means that the time that she spent driving at 45 miles per hour is (6 - t) hours.
Distance = speed × time
Distance covered while driving 50 miles per hour is
50t
Distance covered while driving 45 miles per hour is
45(6 - t)
Since the total distance that she drove is 290 miles, it means that
50t + 45(6 - t) = 290
50t + 270 - 45t = 290
50t - 45t = 290 - 270
5t = 20
t = 20/5 = 4
At 45 miles per hour, she drove at
6 - 4 = 2 hours
If wy is congruent to xy, then from w to y is equal to the distance between x and y. According to the figure, both distances are 3m-4 each. Therefore the perimeter is the sum of the three sides, namely:
![p = m + (3m-4) + (3m-4)=76in](https://tex.z-dn.net/?f=p%20%3D%20m%20%2B%20%283m-4%29%20%2B%20%283m-4%29%3D76in)
Solving for m:
![m + (3m-4) + (3m-4)=76](https://tex.z-dn.net/?f=m%20%2B%20%283m-4%29%20%2B%20%283m-4%29%3D76)
![7m-8=76](https://tex.z-dn.net/?f=7m-8%3D76)
![7m=84](https://tex.z-dn.net/?f=7m%3D84)
![m=12](https://tex.z-dn.net/?f=m%3D12)
