HELP ASAP!! WILL GIVE BRAINLIEST Andrew measured the time it took for an apple to fall 50 feet as 1.95 seconds, but his calculations show that it should be 1.77 seconds. What was his experimental error?

The given problem is : −4.5 + 4.2 + 5.6 − 7.3

The order for solving an arithmetic problem is as follows :

Parentheses,

Exponentiation,

Multiplication,

Addition,

Subtraction,

We can rewrite the given problem as : 4.2 + 5.6 - 7.3 - 4.5

Taking 4.2 and 5.6 together in bracket : (4.2 + 5.6) - 7.3 - 4.5

= 9.8 - 7.3 - 4.5

= 2.5 - 4.5

= -2

Hence, the answer for given problem is -2, but Andrew get -21.6 which is wrong.

ok
