Answer:

25.02 s

Step-by-step explanation:

velocity = distance/time

rearrange for time:

time = distance/velocity

time = -58.3m/-2.33 m/s

time = 25.02s

A new cruise ship line has just launched 3 new ships: the Pacific Paradise, the Caribbean Paradise, and the Mediterranean Par

Elenna [48]

Answer:

Pacific Paradise deluxe state rooms=116

Caribbean Paradise deluxe state rooms = 127

Mediterranean Paradise deluxe state rooms = 333

Step-by-step explanation:

Hi, the numbers are doubled, the correct values are:

Caribbean Paradise has 11 more deluxe staterooms than the Pacific Paradise.

Mediterranean Paradise has 15 fewer deluxe staterooms than three times the number of deluxe staterooms on the Pacific Paradise.

Total number of deluxe staterooms for the three ships is 576.

So, to solve we have to write 3 equations.

C =11 +P

M = P3-15

C+M+P =576

Where:

C: number of Caribbean Paradise deluxe state rooms
M: number of Mediterranean Paradise deluxe state rooms
P: number of Pacific Paradise deluxe state rooms

Replacing values in the total ships equation:

(11 +P) + (P3-15)+P =576

Solving for P:

11 -15 +P+P+3P =576

-4 +5P =576

5P =576+4

5P =580

P = 580/5

P=116

Replacing P in each ship's equation

C = 11 +P= 11 +(116) =127

M =3P -15 = 3 (116)-15 = 333

What is the area of the triangle? Please help

juin [17]

Answer:

6 square inches

Step-by-step explanation:

The formula for area of a triangle is:

1/2(b*h)

Therfore;

b=4, h=3

So,

1/2(4*3)

1/2(12)

=1/2 * 12

= 6 square inches

nikdorinn [45]

Answer:

R = 7,34 km

Ф = 63,43° north of east

Step-by-step explanation:

Let´s analyze each movement and find its perpendicular components. Then, we are going to add the components along the x and y axes to get the resultant and finally to calculate its magnitude and direction.

To determine the perpendicular components, we will use right triangles trigonometrics ratios.

Please see images for each displacement in attached file.

Displacement A: 2.50 km and 45° north of west

Ax= AcosФ = 2.50cos45° = 1.77 km (neg. direction)

Ay= AsenФ = 2.50sen45° = 1.77 km (pos. direction)

Displacement B: 4.70 km and 60° south of east

Bx= BcosФ = 4.70cos60° = 2,35 km (pos. direction)

By= BsenФ = 4.70sen60° = 4,07 km (neg. direction)

Displacement C: 1.30 km and 25° south of west

Cx= CcosФ = 1.30cos25° = 1,18 km (neg. direction)

Cy= CsenФ = 1.30sen25° = 0.55 km (neg. direction)

Displacement D: 5.10 km due east (0°)

Dx= DcosФ = 5.10 km (pos. direction)

Dy= DsenФ = 0 km

Displacement E: 1.70 km and 5° east of north

Ex= EsenФ = 1.70sen5° = 0,15 km (pos. direction)

Ey= EcosФ = 1.70cos5° = 1.69 km (pos. direction)

Displacement F: 7.20 km and 55° south of west

Fx= FcosФ = 7.20cos55° = 4.13 km (neg. direction)

Fy= FsenФ = 7.20sen55° = 5.90 km (neg. direction)

Displacement G: 2.80 km and 10° north of east

Gx= GcosФ = 2.80cos10° = 2.76 km (pos. direction)

Gy= GsenФ = 2.80sen10° = 0.49 km (pos. direction)

Now, we add the components along the x- and y- axis to find the components of the resultant (R):

Rx = Ax + Bx + Cx + Dx + Ex + Fx + Gx

Ry = Ay + By + Cy + Dy + Ey + Fy + Gy

Therefore,

Rx= (-1.77)+(2.35)+(-1.18)+(5.10)+(0.15)+(-4.13)+(2.76)

Ry= (1.77)+(-4.07)+(-0.55)+(0)+(1.69)+(-5.90)+(0.49)

Note: minus (-) symbol to negative directions

Rx = 3.28 km

Ry = - 6.57 km

Let´s use the Theorem of Pythagoras to find the magnitud ot the resultant:

$R = \sqrt{Rx^{2} +Ry^{2} }$

$R =\sqrt{(3.28)^{2}+(-6.57)^{2} }$

R = 7,34 km

To find the direction of the resultant:

tanФ = $\frac{Ry}{Rx}$

tanФ = $\frac{6.57}{3.28}$

tanФ = 2.00

Ф = tan-1 (2.00)

Ф = 63,43° north of east
