Answer:
16-x*(-7)=-154
7x =-154-16
7x/7=-170/7
X=-24.29
Step-by-step explanation:
Let x represent "my number"
49 divided by 369 is 0.13279133 and 369 divided by 49 is 7.53061224
Answer:
$49.82
Step-by-step explanation:
To find the cost of the watch with tax, multiply the price by 1.095:
45.5(1.095)
= 49.8225
Round to the nearest hundredth:
= 49.82
So, the final cost is approximately $49.82
The answer is D. y = 1/2(x+2)^2 -3
Step-by-step explanation:
I just put each answer choice into a graphing calculator and chose the one that was equivalent, D. came out to be right
Step-by-step explanation:
DEFINITION: Besting: the clockwise totation (0° to 360°) from North to any line.
A) Calculate the bearings of D from A:
bearings of D from A =x
looking the picture:
x=48°+55°+180°
x+103°+180°
x=283°
B)Calculate the bearings of A from C:
bearings of A from C =y
180°+55°=y
y=235°
C) Calculate the distance between A and B:
The angle in B is 74° (Because 55°+51°+74°=180°)
Using the Law of sines:

D)Calculate the distance between D and C:
Using the Law of cossines:

E) A Helicopter is hovering at A at a height of 2.5Km, find angle of elevation of helicopter from C:
The triangle HBA is rectangle

α=7,49°
