Sam created a porch that was part wooden and part concrete, as shown in the figure below.
note: figure not drawn to scale
if a = 18 ft, b = 24 ft, and c = 30 ft, what is the total area of the porch? assume that the wooden part is a right triangle and the concrete part is a square.
a.
186 ft2
b.
102 ft2
c.
1,260 ft2
d.
1,116 ft2

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
