Alex Ar [27]

Answer:

5789 digits

Step-by-step explanation:

Given that the number of pages ares: 1,724  

As we know that:

  • (from 1 - 9) there are 9 one-digit numbers
  • (from 10- 99) there are 90 two-digit numbers
  • (from 100 - 999) there are 900 three-digit numbers
  • (from 1,000 - 1,724) there are 725 four-digit numbers

So the total are:

= 9(1)+90(2)+900(3)+725(4)\\\\= 9+180+2,700+2,900\\\\= 5,789\ digits

Paraphin [41]

Answer:

4/5

Step-by-step explanation:

To find the slope we pick two points

(-2,0) and (3,4)

We can find the slope from

m = (y2-y1)/(x2-x1)

    = (4-0)/(3--2)

    = (4-0)/(3+2)

     = 4/5
