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 1
Answer:

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

Given that a - b = 3 and ab=5, find, without the use of a calculator,
the value of a +b?

Answers

Answer:

√29

Step-by-step explanation:

We are here given that ,

  • a - b = 3
  • ab = 5 .

Now square the first equation ,

⇒ a - b = 3

⇒ ( a - b)² = 3²

⇒ a² + b² - 2ab = 9

⇒ a² + b² - 2(5) = 9

⇒ a² + b² -10 = 9

⇒ a² + b² = 9 + 10

⇒ a² + b² = 19

  • Adding 2ab both sides ,

⇒ a² + b² + 2ab = 19 + 2(5)

⇒ (a + b)² = 19 + 10

⇒ ( a + b)² = 29

⇒a+b=√29.

Is 4,400 is 10 times as much as 440

Answers

to do question we have to multiply 10 and 440: ("x times as much" is x Multiplied by", so "twice as much as 4 is 8", or "3 times 4 is 12),

If I read 52 pages in 2 hrs and Tim reads 1/4 more in 2 and1/2 hr. who read faster?

Answers

They read at the same speed
If we split the time where you read into half hour intervals we would have
13 pages per 30 minutes
and since (1)/(4)* 52= 13 and the time added is 30 minutes we know that You and Tim read at the same speed. 
so Tim read 13 pages =1/4 of 52 pages in (2 and 1/2 hr) - (2hrs) = 1/2 hr
So Tim will read 26 pages in 1 hr and  that means Tim read 52 pages in 2 hrs, the same with You! The answer its that bouth read in the same time.

Answers

48 tiles divided up into 8 rows equals 6 tiles in each row.  If each row has 6 blue tiles, then all of the tiles are blue :( She does not need any purple tiles.  Are you sure that you wrote your question correctly?
She will not need any purple tiles because all of her tiles, 8*6, 48, will be blue.
