X = 700

You divide 2800 by 4 to get 'x'

2800 divided by 4 = 700

4 • 700 = 2800

he length of a rectangle is three times the width. The perimeter is 240 inches. Find the length and the width.

sammy [17]

Answer:

Length = 90 inch.

width = 30 inch

Let width of the rectangle = x inch.

So the length = 3x inch.

Perimeter = 2(length + width) = 2 (3x + x) = 8x.

So,

length = 3x = 3(30) = 90 inch.

width = x = 30 inch

The common ratio in a geometric series is 4 and the first term is 3.

kodGreya [7K]

Answer:

The sum of the first 8 terms in the series is 65535.

Step-by-step explanation:

We have,

The common ratio in a geometric series, r = 4

First term of GP is, a = 3

It is required to find the sum of the first 8 terms in the series. The sum of first n terms of a GP is given by :

$S_n=\dfrac{a(r^n-1)}{r-1}, r>1$

Here, n = 8

$S_8=\dfrac{3\times ((4)^8-1)}{4-1}\\\\S_8=65535$

So, the sum of the first 8 terms in the series is 65535.

The radius of the Moon is 1700 km, and the radius of the Earth is 6350 km. A scale model of the Earth and the Moon is made. In t

Reil [10]

Answer:

1) 12.7 cm

2) 8580.24 cm³

Step-by-step explanation:

given,

Radius of moon(Rm) = 1700 Km Radius of Earth(Re) = 6350 km

Model radius of Moon(Mm) = 3.4 cm

2) Volume of earth model = $\dfrac{(R_e)^3}{(R_m)^3}\times \dfrac{4}{3}\pi (M_m)^3$

= $\dfrac{(6350)^3}{(1700)^3}\times \dfrac{4}{3}\pi (3.4)^3$

= 8580.24 cm³

1) radius of earth = $\dfrac{R_e}{R_m}\times M_m$

= $\dfrac{6350}{1700}\times 3.4$

= 12.7 cm
