How many times larger is 4x10^7 than 5x10^5

irina1246 [14]

Answer:

8 times larger

Step-by-step explanation:

4 · $10^{7}$ = 4 · 10 · 10 · 10 · 10 · 10 · 10 · 10

4 · 100 · 100 · 100 · 10

400 · 10000 · 10

= 40000000

5 · $10^{5}$ = 5 · 10 · 10 · 10 · 10 · 10

50 · 100 · 100 · 10

5000 · 1000

= 5000000

40000000 ÷ 5000000 = 8

Test 645 for divisibility by 2, 3, 5, 9, and 10.

zaharov [31]

Answer:To test for divisibility, you look for answers that are whole numbers when you divide 59859 by either 2, 3, 5, 9, or 10.

To start divide it by each of them:

59859/2=29929.5

59859/3= 19953

59859/5= 11971.8

59859/9= 6651

59859/10= 5985.9

Now look at which of the choices are whole numbers

3 and 9 are the only non decimal numbers, therefore, C would be your answer.
