Katya cut part of the jump rope off to make it shorter. The new length is 8 and StartFraction 1 over 6 EndFraction feet. The difference between the original length and the new length is StartFraction 5 over 6 EndFraction foot. The equation x minus 8 and StartFraction 1 over 6 EndFraction = StartFraction 5 over 6 EndFraction can be used to represent this problem, where x is the original length of the rope. What was the original length of the rope? 7 and one-thirdfeet
8 and two-thirdsfeet
9 feet
10 feet

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
