Answer:
6 ft above ground.
Step-by-step explanation:
The roller coaster starts from an elevation of +20 feet from the ground.
Now, it first corns 78 ft, then drops 85 ft.
So, the final elevation will be (20 + 78 - 85) = 13 feet above the ground on the second hill.
Again, it climbs 103 ft. and drops 110 ft. and finally his elevation will be = 13 + 103 - 110 = 6 ft above ground. (Answer)
No it not true 8÷5=0.625
Then you know that
<span>4 + 5/8 = 4 + .625 </span>
<span>They are equal. </span>
<span>Simple arithmetic tells you that that 4+ .625 = 4.625 </span>
<span>Which in itself is equal to 4 and 5/8</span>
Answer:
<
