There are thirty houses on a street. twenty-four of them have pumpkins on their porch. what percent do not have pumpkins on there porch?

20%

Step-by-step explanation:

if you divide 100 by 30 you get 3.33333

then you times that by the number of houses that do have pumpkins and get 80%

100-80 = 20

(also there and 5 sets of 6 in 30 and 1/5 of a number is always 20%)

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
