A roller coaster starts from a deck at an elevation of 20 feet above the ground. On the first hill it climbs 78 feet and then drops 85 feet. On the second hill the coaster climbs 103 feet and then drops 110 feet. How far below or above the deck is the coaster after the second hill?
A) 14 feet below
B) 14 feet above
C) 6 feet below
D) 6 feet above ***
But whats the answer
the asnwer is 14 feet below and yall better add me on snap when i accept it yall better text me i need clout
To find out how far below or above the deck the coaster is after the second hill, we can add up the changes in elevation as the coaster climbs and drops.
First, let's calculate the total change in elevation for the first hill. The coaster climbs 78 feet and then drops 85 feet. The net change in elevation for the first hill is -7 feet (78 - 85 = -7).
Next, let's calculate the total change in elevation for the second hill. The coaster climbs 103 feet and then drops 110 feet. The net change in elevation for the second hill is -7 feet again (103 - 110 = -7).
Now, let's add up the net changes in elevation for both hills. -7 feet + -7 feet = -14 feet.
Since the net change in elevation is -14 feet, the coaster is 14 feet below the deck after the second hill. Therefore, the correct answer is:
D) 6 feet above.
So, the roller coaster is 6 feet above the deck after the second hill.
I ain't going to add you on snap.
elevation=20+78-85+103-110= ?
and, you are correct
