Answer:
6 hours
Step-by-step explanation:
If you add all of them together and estimated the answer than your estimation should be about 6 hours.
We must follow order of operations rules (PEMDAS).
Thus, mult. and div. must be carried out before addn. and subtrn.
Calculate the quotient of (-2/5) and (4/5). In other words, divide (4/5) into (-2/5). Invert (4/5) and multiply:
(-2/5)(5/4) = -1/2
Then we have, in place of the original expression, the following expression:
-3/4 - 1/2 + (2 1/2).
Rewriting 2 1/2 as an improper fraction and elim. the parentheses yields:
-3/4 - 2/4 + 5/2, or -3/4 - 2/4 + 10/4, since the LCD is 4.
This yields 5/4 (answer)
Step-by-step explanation:
the distance can be seen as Hypotenuse of a right-angled triangle with its legs being the x and y coordinate differences.
so, we use Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
distance² = (-10 - -3)² + (-9 - 8)² = (-7)² + (-17)² = 49+289 =
= 338
distance = sqrt(338) = sqrt(2×169) = 13×sqrt(2) =
= 18.38477631...
