c)         d)

7)    a.    kg                  b.    cm               c. 20 cm

d.   kg                  e. 10 g             f.  kg

Step-by-step explanation:

c)     -  

First we will change to improper fraction and then solve

=  

=

we will now change to mixed number

=

d)  

we will first change it to improper fraction and then solve

=

=

=

we can reduce the fraction

=

we will change it mixed number

=

7)  

a.     of 23

=     × 23

=  

=  kg

b.   of 10 cm

=   × 10 cm

=  cm

=  cm

c.   of 24cm

=       × 24 cm

6 will divide 24

=5 × 4 cm

= 20 cm

d.    of  33 kg

=    ×  33 kg

=  kg

= kg

e.   of  35 g

=     ×  35 g

7 will go into 35

=2×5 g

=10 g

f.  of  31 kg

=  ×  31 kg

= kg

=  kg

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
