Answer:

The distance traveled by the B737-400 aircraft in 5 hours is 2,000 miles

Step-by-step explanation:

Average speed = 400 miles per hour

Distance = 400t

t= 5

Total distance = 400t at t hours

Total distance when t = 5 hours

Total distance traveled = 400t

= 400 × 5

= 2,000 miles

Total distance travelled = 2,000 miles

The distance traveled by the B737-400 aircraft in 5 hours is 2,000 miles

hope this helps

Assignment: Using Prime Factorization Investigation
damaskus [11]

Answer:

  1. 3(2 +7)
  2. 9(3 +5)
  3. 16(2 +3)
  4. 15(2 +5)
  5. 8(11 +3)

Step-by-step explanation:

  1. 6 + 21 = 2·3 + 3·7 = 3(2 +7)
  2. 27 + 45 = 3^3 + 3^2·5 = 9(3 +5)
  3. 32 + 48 = 2^5 + 2^4·3 = 16(2 +3)
  4. 30 + 75 = 2·3·5 + 3·5^2 = 15(2 +5)
  5. 88 + 24 = 2^3·11 +2^3·3 = 8(11 +3)

In each case, the factor outside parentheses is the greatest common factor, the product of the prime factors common to both numbers. When the same factor has different powers, the least power is the common factor.
