Answer:

a) 18

b) 6

Step-by-step explanation:

a) The proportion can be written as ...

MS/LC = 3/2 = MS/12

Multiplying by 12 gives ...

MS = 12(3/2) = 18

There are 18 buildings in the Main Street district.

b) The proportion of stores to total buildings in the Main Street district is ...

stores : non stores = 1 : 2

stores : (stores + non-stores) = 1 : 3

1/3 of the buildings in the MS district are stores. There are ...

(1/3)(18) = 6 . . . stores in the Main Street district

Find the oth term of the geometric sequence 9, -18, 36, ...

Sphinxa [80]

Answer:

2304

Step-by-step explanation:

Given :-

A geometric sequence is given to us which is 9 , -18 , 36.

And we need to find out the 9th term of the sequence. Here firstly we should find the Common Ratio and then we can substitute the respective values in the formula to find the nth term of a geometric sequence .

Common Ratio :-

$:\implies$ CR = -18÷ 9 = -2

The 9 th term :-

$:\implies$ T_n = arⁿ - ¹

$:\implies$ T_9 = 9× (-2) ⁹ - ¹

$:\implies$ T_9 = 9 × (-2)⁸

$:\implies$ T_9 = 9 × 256

$:\implies$ T_9 = 2304

Hence the 10th term is 2304.

What is the missing number in the series? 1, 16, 81, __, 625, 1296

Alinara [238K]

Answer:

256

Step-by-step explanation:

We are given the series

1, 16, 81, __, 625, 1296

The missing number in the sequence is the fourth term

From the above sequence, we know that

1, 4², 9² , __, 25² , 36²

Difference between first term = 4 - 1 = 3

9 - 4 = 5

x - 9 = 7

x = 9 + 7 = 16

Hence, the fourth term = 16²

= 256

Bas_tet [7]

Two trapezoid are similar
so it has some scale factor
look longer base of a big trap is 8 mi,and longer base of shorter trap is 4mi.
so that is half of big trapezoid.
so little trapezoid base should be 1 as big trap's shorter base is 2mi
