Answer:
-3.5 14
Step-by-step explanation:
2y=-7x+28
y=-3.5x+14
Answer:
x = 15 cm
Step-by-step explanation:
All the ratio of corresponding sides should be equal
10 corresponds to x
16 corresponds to 24
12 corresponds to 18
<em>Finding the ratio of the known pairs:</em>
<em>Similarly 10 is to x should be 2 is to 3. Finding x:</em>

So x = 15.
Answer: C
<u>Step-by-step explanation:</u>
(x - 3)² = 0
(x - 3)(x - 3) = 0
x(x - 3) -3(x - 3) = 0
x² - 3x -3x + 9 = 0
x² - 6x + 9 = 0
17 feet...use Pythagorean theorem to solve the length of the four hypotenuse of the four triangles you can produce from that shape.
Answer:
Boat traveled 553.24 feet towards the lighthouse.
Step-by-step explanation:
In the figure attached AB is the light house of height 200 feet.
Angle of depression of the boat from the top of a lighthouse = angle of elevation of the lighthouse from the boat = 14°52'
so 1' =
degree
so angle of elevation at point C = 14 + 
So angle of elevation from C = (14 + 0.87) = 14.87°
Similarly, when boat arrives at point D angle of elevation = 45°10' = 45 +
= 45.17°
Now we have to calculate the distance CD, traveled by the boat.
In ΔABC
tan14.87 = 
0.2655 = 
BC = 
BC = 753.239 feet
Similarly in ΔABD
tan45.17 = 
1 = 
BD = 200 feet
So distance CD = BC - BD
CD = 753.239 - 200
= 553.24 feet
Therefore, Boat traveled 553.24 feet towards the lighthouse.
