CaHeK987 [17]

How much you need pay?
65x(1-25%)
=65x75%
=65x0.75
=48.75
Your answer should be $48.75.

A floor rug is rectangular in shape. The width of the rug is 2 ft less than its length. The perimeter of the rug is 36 ft.

Ganezh [65]

Answer

Perimeter of rectangle, P = 2L + 2W

P = 36ft

Width, W

Length, L = W + 2ft

Perimeter of rectangle, P = 2L + 2W

Given; P = 36ft

36ft = 2W + 2(W + 2ft)

36ft = 2W + 2W + 4ft

32ft = 4W

8ft = W

L = W + 2ft

L = 8ft + 2ft

L = 10ft

What is the formula for the nth term of the given sequence 100, 20, 4, …

Naily [24]

Answer:

$a_n=100 \left(\dfrac15\right)^{n-1}$

Step-by-step explanation:

General equation of geometric sequence: $a_n=ar^{n-1}$

Given:

a₁ = 100
a₂ = 20
a₃ = 4

$\implies a_1=a=100$

$\implies a_2=100 \cdot r=20$

$\implies a_3=100 \cdot r^2=4$

Common ratio:

$r=\dfrac{a_3}{a_2}=\dfrac{4}{20}=\dfrac15$

Therefore:

$a_n=100 \left(\dfrac15\right)^{n-1}$
