Which one is the answer??
BARSIC [14]

Answer:

B

Step-by-step explanation:

City X = 3 * 10^5            Given

City Y = 6 * 10^6

Times larger

6 * 10^6

3 * 10^5

Do the division

6*10^6/3^10^5 = 60 * 10^5/(3 * 10^5)   Note 10^5 will cancel

60/3 = 20 City y is 20 times City x

Population Difference

6,000,000

   300,000

5,700,000

Just from the numbers I've given you, A is incorrect. The answer is 20 not 2.

B is the answer

C is wrong. X is 5.7 million less.

D See the answer for C.

Answer:

  2. (only)

Step-by-step explanation:

The Pythagorean theorem tells you the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse. To determine if these are right triangles, determine if that condition is met.

  1. 3^2 +5^2 = 9 + 25 = 34 ≠ (√35)^2 . . . . not a right triangle

  2. 5^2 +4^2 = 25 +16 = 41 = (√41)^2 . . . a right triangle

  3. 6^2 +8^2 = 36 +64 = 100 ≠ (√10)^2 . . . . not a right triangle

  4. 3^2 +3^2 = 9 +9 = 18 ≠ (3√3)^2 = 27 . . . . not a right triangle
