A ship sails on a bearing of 020° for 30 km.

zepelin [54]

Answer:

The ship travels approximately 10.261 meters to the East.

Step-by-step explanation:

At first we introduce a graphical description of the statement as an attachment below. Let suppose that bearing is respect to the North-direction, then the change in position in the East direction is modelled by the following Trigonometric formula:

$x = r\cdot \sin \theta$ (1)

Where:

$r$ - Distance travelled by the ship, measured in kilometers.

$\theta$ - Bearing angle, measured in sexagesimal degrees.

$x$ - Distance component in the east direction, measured in kilometers.

If we know that $r = 30\,km$ and $\theta = 20^{\circ}$ , then the distance in the East direction is:

$x = (30\,km)\cdot \sin 20^{\circ}$

$x \approx 10.261\,m$

The ship travels approximately 10.261 meters to the East.

V= 3.14 r2 h
1. 3.14 x 14 x 14 x 18 = 11083.54
2. 3.14 x 13 x 13 x 17 = 9025.8
3. 3.14 x 15 x 15 x 14 = 9896.02
4 .3.14 x 12 x 12 x 20 = 9047.79
so the order would be the second then the forth then the third then the first

Manny has four pieces of carpet in the shape of a square like the one shown. He wants to use them together to carpet a portion o

KengaRu [80]

Answer:

the area of the space he can cover with carpet = 16x⁴ yards²

Step-by-step explanation:

The shape of the square is not shown in this question.

Let assume that the base of the shape of the square is 2x² yards.

and Manny has four of that.

Then side we known the base, we can calculate for the area of the square.

Area of a square = l²

Area of a square = (2x² yards)²

Area of a square = 4x⁴ yards²

However, since Manny has four pieces of that carpet and wants to use them together to carpet a portion of his basement.

Let the pieces of the carpet be carpet A, B, C and D

where; their side is 2x² yards, then their area = 4x⁴ yards²

the area of the space he can cover with carpet = A+B+C+D

the area of the space he can cover with carpet = 4x⁴ yards² + 4x⁴ yards² + 4x⁴ yards² + 4x⁴ yards²

the area of the space he can cover with carpet = 16x⁴ yards²
