Answer:
The expression 9n + 1 represents the perimeter
sum of the sides of the triangle, equal to the perimeter:
x + 3n+2 + 2n-1 = 9n + 1
x + 5n + 1 = 9n + 1
x = 9n +1 - 5n -1
Answer: x= 4n

Answer: The height of hill is 125 feet.
Step-by-step explanation:
Given that velocity of the rollercoaster is ![v= \sqrt{(v_\limit{0}^{2} )+64h}](https://tex.z-dn.net/?f=v%3D%20%5Csqrt%7B%28v_%5Climit%7B0%7D%5E%7B2%7D%20%29%2B64h%7D)
Where,
is initial velocity and h is height from top of hill.
and v is velocity at height h.
Initial Velocity
is 10feet/sec at top of hill.
Also, Velocity at bottom of the hill is 90feet/sec.
Therefore, the value of h at top of the hill is h=0 and value of h at bottom of the hill is h=h
![v= \sqrt{(v_\limit{0}^{2} )+64h}](https://tex.z-dn.net/?f=v%3D%20%5Csqrt%7B%28v_%5Climit%7B0%7D%5E%7B2%7D%20%29%2B64h%7D)
![90= \sqrt{(10)^{2} +64h}](https://tex.z-dn.net/?f=90%3D%20%5Csqrt%7B%2810%29%5E%7B2%7D%20%2B64h%7D)
![90^{2}= 10^{2} +64h](https://tex.z-dn.net/?f=90%5E%7B2%7D%3D%2010%5E%7B2%7D%20%2B64h)
8100=100+64h
8000=64h
h=125 feets.
Thus, The height of hill is 125 feet.
1 ton= 2000 pounds
STEP 1:
Convert each car's weight to pounds:
= 2000 pounds + 1400 pounds
= 3400 pounds per car
STEP 2:
multiply each car's weight in pounds by the total number of cars
= 3400 pounds * 6 cars
= 20,400 pounds total
ANSWER: The truck is transporting 20,400 pounds.
Hope this helps! :)
Answer:
the factors of 12 are 1, 2, 3, 4, 6, and 12. So the greatest common factor of 9 and 12 is 3. So you divide both sides by 3. So the simplest form of 9/12 is 34.
