Only blue and white vans are made at a factory. The ratio of the number of blue vans to the number of white vans is 4 : 3 write
amid [387]

Answer:

4/7

Step-by-step explanation:

Number of Blue vans = 4

Number of white vans = 3

Total number of vans = Number of Blue vans + Number of white vans

= 4 + 3

= 7 vans

Number of blue vans : Number of white vans = 4 : 3

Fraction of vans that are blue = Number of Blue vans / Total number of vans

= 4 / 7

Fraction of vans that are blue = 4/7

Find the perimeter use pi
balandron [24]
Since d x pi = circumference
I use 3.14 as pie

I did 9 x pi = 28.26 I DID NOT divide this by two because there are three half circles and 28.26 counts as two of them

Since there is another half circle I divide 28.26 by 2

28.26 + 14.13 = 42.39

Now plus the bottom length

42.39 + 9 = 51.39
