Satellites KA-1212 and SAL-11 have spotted a UFO. Scientists want to determine its distance from KA-1212 so they can later deter

ch4aika [34]

Answer:

The distance of UFO from KA-1212 is 1229.7 km.

Step-by-step explanation:

We are given that,

Distance between the satellites = 900 km

Angle made by the satellite KA-1212 = 60°

Angle made by the satellite SAL-11 = 75°

So, from the figure below,

The third angle is given by = 180° - (60°+75°) = 180° - 135° = 45°

Then, using the law of sines, we have,

$\dfrac{x}{\sin 75}=\dfrac{900}{\sin 45}\\\\x=\dfrac{900\times \sin 75}{\sin 45}\\\\x=\dfrac{900\times 0.966}{0.707}\\\\x=\dfrac{869.4}{0.707}\\\\x=1229.7$

<h3>Thus, the distance of UFO from KA-1212 is 1229.7 km.</h3>

The total cost to play paintball can be represented by the expression (48x+54). If Rocco and five friends split the cost equally

KonstantinChe [14]

Answer:

8x + 9

Step-by-step explanation:

The total number of people splitting the cost equally = Rocco and five friends = 6 people

The total cost to play paintball can be represented by the expression (48x+54)

The cost for each person is calculated as: The total cost to play paintball/ Total number of people

= (48x+54)/6

= 48x/6 + 54/6

= 8x + 9

Therefore, the cost for each person is

8x + 9

What is the solution to X and Y in these equations 3x + 9y=60 and -3x + y=30

Roman55 [17]

Answer:

x= -7 y=9

Step-by-step explanation:

3x +9y= 60 [1]

-3x +y=30 [2] rewrite this as the following: y=30+3x

With equation [2] you substitute it into equation [1]

so it will now be: 3x+ 9(30 +3x) =60

3x+270 +27x=60

Group the like terms

3x+27x=60-270

30x=-210

x=-7

Use this answer into the same equation

So: 3(-7)+9y=60

-21 +9y=60

9y=60+21

9y=81

y=9
