Answer:

7/10

Step-by-step explanation:

To find the area of a rectangle you need to mulitiply the length and the width.

Length= 7/8.

Width= 4/5

7/8 × 4/5= 7/10.

A ship leaves port at noon and has a bearing of S29oW. The ship sails at 20 knots. How many nautical miles south and how many na

ira [324]

Answer:

Approximately $58.2\; \text{nautical miles}$ (assuming that the bearing is ${\rm S$29^{\circ}$W}$ .)

Step-by-step explanation:

Let $v$ denote the speed of the ship, and let $t$ denote the duration of the trip. The magnitude of the displacement of this ship would be $v\, t$ .

Refer to the diagram attached. The direction ${\rm S$29^{\circ}$W}$ means $29^{\circ}$ west of south. Thus, start with the south direction and turn towards west (clockwise) by $29^{\circ}$ to find the direction of the displacement of the ship.

The hypothenuse of the right triangle in this diagram represents the displacement of the ship, with a length of $v\, t$ . The dashed horizontal line segment represents the distance that the ship has travelled to the west (which this question is asking for.) The angle opposite to that line segment is exactly $29^{\circ}$ .

Since the hypotenuse is of length $v\, t$ , the dashed line segment opposite to the $\theta = 29^{\circ}$ vertex would have a length of:

$\begin{aligned}& \text{opposite (to $\theta$)} \\ =\; & \text{hypotenuse} \times \frac{\text{opposite (to $\theta$)}}{\text{hypotenuse}} \\ =\; & \text{hypotenuse} \times \sin (\theta) \\ =\; & v\, t \, \sin(\theta) \\ =\; & v\, t\, \sin(29^{\circ})\end{aligned}$ .

Substitute in $\begin{aligned} v &= 20\; \frac{\text{nautical mile}}{\text{hour}}\end{aligned}$ and $t = 6\; \text{hour}$ :

$\begin{aligned} & v\, t\, \sin(29^{\circ}) \\ =\; & 20\; \frac{\text{nautical mile}}{\text{hour}} \times 6\; \text{hour} \times \sin(29^{\circ}) \\ \approx\; & 58.2\; \text{nautical mile}\end{aligned}$ .

Nicoles school is delling tickets to a play. On the first day of ticket sales the school sold 6 senior citizen tickets and 10 st

murzikaleks [220]

Answer:the price of one senior citizen's ticket is $4

the price of one student ticket is $10

Step-by-step explanation:

Let x represent the price of one senior citizen's ticket

Let y represent the price of one student ticket.

On the first day of ticket sales the school sold 6 senior citizen tickets and 10 student tickets for a total of $124. This means that

6x + 10y = 124 - - - - - - - - - - 1

The school took in 98 on the second day by selling 12 senior citizen tickets and 5 student tickets. This means that

12x + 5y = 98 - - - - - - - - - - - 2

Multiplying equation 1 by 2 and equation 2 by 1, it becomes

12x + 20y = 248

12x + 5y = 98

Subtracting, it becomes

15y = 150

y = 150/15 = 10

Substituting y = 10 into equation 1, it becomes

6x + 10 × 10= 124

6x + 100 = 124

6x = 124 - 100 = 24

x = 24/6 = 4
