Answer 2

Answer:

1. a.b.

hundreds   tens    ones  tenths hundredths thousandhs

 a.  4                2      8 .         0              0                1

 b.  1                 7       3.            1               7                8

2.  9a^2-6a^3-6a^4-3a^2+7a^3+5a^2=

     9a^2-3a^2+5a^2=12a^2

     -6a^3+7a^3=1a^3

    -6a^4

    answer is 12a^2+a^3 -6a^4

3.circumference of a park is 352

 radius of park is 56.0225

area = πr^2

56.0225 * 22/7* 22/7

=9860.02 m

4. area =

outer circles area=  π r²

32*22/7*22/7=

3217 cm

inner circle area= π r²

18*22/7*22/7

=1018 cm

area of path way= 3217-1018=2199 cm

5.ratio of the angles of triangle are   3:5:4

 angles= 3x+5x+4x=180

           = 13x=180

             x= 180/13

           =13.8

              3x= 3*13.8

          4x=4*13.8

           5x=5*13.8

           = 41.1, 55.2, 69
