Answers

Answers:

Sure, let's calculate the answers for each of the given problems:

1) $7 + (-12) + (-3) = -8$

2) $2 + 8 + 7 + (-6) = 11$

3) $13 + 12 + 12 = 37$

4) $6 - 18 + 16 + (-12) + 5 = -3$

5) $24 + 19 + 5 + 3 = 51$

6) $-24 + 2 = -22$

7) $3.4 + 2.7 + 1.3 + (-1.2) = 6.2$

8) $7 + 7 + 7 = 21$

9) $-4 - 7 = -11$

10) $2 + 5 = 7$

11) $-2 + 6 = 4$

12) $-2 + 1 = -1$

13 ) $-15 - 4 = -19$

14) $7 - 19 = -12$

15) $5 + 20 = 25$

16) $-24 + 2 = -22$

17) $-2 + (-7) - 1 = -10$

18) $7 + 13 - 12 = 8$

19) $-15 + 3 - 8 = -20$

20) $-1 - 13 + (-17) = -31$

21) $-3 + 7 + 18 = 22$

22) $14 + 3 - 4 + 1 = 14$

23) $27 - 3 + (-24) = 0$

24) $(14 + 6) - (-5 - 13) = 38$

25) $10 - (5 + (-7) + 2) = 14$

26) $(-3 + 10) - ((5 - 8) + (-10)) = 10$

27) $(-4 + 2) + (-16 - 5) = -23$

28) $(27 + 6) + (-6) = 27$

29) $27 - (-6 + (-6)) = 39$

30) $(16 - 4) - (8 + 12) = -8$

Now, connecting the answers in order:

-8, 11, 37, -3, 51, -22, 6.2, 21, -11, 7, 4, -1, -19, -12, 25, -22, -10, 8, -20, -31, 22, 14, 0, 38, 14, 10, -23, 27, 39, -8.

A military aircraft can travel 740 miles per hour. The distance between Tyndall Air Force Base in Florida and Lakenheath Air Force Base in England is 2,567 miles. How long would it take the aircraft, traveling at top speed the entire route, to make the trip from Tyndall to Lakenhealth? Round to the nearest half hour.

Answers

Answer: 3.5 h

Step-by-step explanation:

1. Data:

a) s = 740 miles / h

b) d = 2,567 miles

c) t = ?

2. Equation:

speed = distance / time

s = d / t

3. Solution:

Solve the equation for t:

s = d / t ⇒ t = d / s

Substitute values:

t = 2,567 miles / (740 miles/h) ≈ 3.47 h ≈ 3.5 h
