A ship is stationary at sea. A tugboat is 27 km away at a bearing of 050°, and a yacht is 21 km from the tugboat at a bearing of 320°.
Draw a scale diagram showing the positions of the three vessels.
Use a scale of 1 cm : 3 km.
Use your diagram to find the distance of the yacht from the ship to the nearest km

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation:

you can download it here

cant

step-by-step explanation: there is no picture

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
