Answer:

T_{n} = \frac{1}{5} T_{n-1} with T₁ = 5000

Step-by-step explanation:

There is a common ratio r between consecutive terms in the sequence, that is

r = \frac{1000}{5000} = \frac{200}{1000} = \frac{40}{200} = \frac{1}{5}

This indicates the sequence is geometric with recursive rule

T_{n} = r T_{n-1}

Here tr = \frac{1}{5} , thus

T_{n} = \frac{1}{5} T_{n-1} , T₁ = 5000

the dimensions of a smaller rectangle are 3ft by 9ft the dimensions of a larger rectangle are 5ft by 15ft find the ratio of the
Alexxandr [17]

The ratio of the area of the smaller rectangle to the area of the larger

rectangle is \frac{9}{25}

Step-by-step explanation:

The formula of the area of a rectangle is A = l × w, where l and w

are its dimensions

  • The dimensions of a smaller rectangle are 3 ft by 9 ft
  • The dimensions of a larger rectangle are 5 ft by 15 ft

We want to find the ratio of the area of the smaller rectangle to

the area of the larger rectangle

∵ The dimensions of the smaller rectangle are 3 ft and 9 ft

∴ The area of the smaller rectangle = 3 × 9 = 27 feet²

∵ The dimensions of the larger rectangle are 5 ft and 15 ft

∴ The area of the smaller rectangle = 5 × 15 = 75 feet²

Let us find the ratio of the area of the smaller rectangle to the area

of the larger rectangle

→ smaller rectangle  :  larger rectangle

→ 27                           :  75

Divide the both terms of the ratio by 3

→ 9                             :  25

The two terms of the ratio do not divisible by any other number

∴ The simplest form of the ratio is 9 : 25

∴ The ratio of the area of the smaller rectangle to the area of the larger

   rectangle = \frac{9}{25}

The ratio of the area of the smaller rectangle to the area of the larger

rectangle is \frac{9}{25}

Solve 2/3=1/4k<br> The solution is k=
aleksley [76]

To find k, divide both sides by 1/4

K = 2/3 / 1/4

When dividing by a fraction flip the second fraction over then multiply:

K = 2/3 x 4/1 = (2 x 4) / (3 x 1) = 8/3

K = 8/3 = 2 and 2/3
