Thirty clowns are in clown car. If all of the clowns in the car are either happy clowns or sad clowns, all of
the following are possible ratios of sad clowns to
happy clowns EXCEPT:
a).1:2
b). 1:1
c). 3:7
d). 4:1
e). 5:2

E, 5:2

Step-by-step explanation:

1:2

1/3 x 30 = 10 .  2/3 x 30 = 20

1:1

1/2 x 30 = 15

3:7

3/10 x 30 = 9  7/10 x 30 = 21

4:1

4/5 x 30 = 24 .  1/5 x 30 = 6

5:2

5/7 x 30 = 21.43 (this is a decimal so it does not work)

50=33x+22

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
