Susan paid $240 to have her house decorated. The materials used to decorate the house coast $115, and service was charged at $5

Nataly [62]

Answer:

$240 =5x +115$

And we can solve for x in order to find the number hours using to decorate the house.

We can subtract in both sides 115 and we got:

$240-115= 5x$

$125 = 5x$

And now we can divide both sides by 5 and we got:

$x= 25$

So then the number of hours spent to decorate the house are 25

Step-by-step explanation:

Based on the information given we can model this function with this formula:

$y = mx+b$

Where y represent the total cost paid, m the cost per hour representing the slope and x the number of hours worked and finally b the initial cost for the materials. Then our function is given by:

$240 =5x +115$

And we can solve for x in order to find the number hours using to decorate the house.

We can subtract in both sides 115 and we got:

$240-115= 5x$

$125 = 5x$

And now we can divide both sides by 5 and we got:

$x= 25$

So then the number of hours spent to decorate the house are 25

as viewed from Cliff 360 m above sea level the angle of depression of a ship is to 28° how far is the ship from the shore

andrezito [222]

The distance of the ship from the shore is given by:
tan θ=opposite/adjacent
θ=28°
adjacent=x
opposite=360 m

substituting the values in our equation we get:
tan 28=360/x
solving for x we get
x=360/tan 28
x=677.06 m
