Answer:
Option B. n
Step-by-step explanation:
we know that
A regular polygon is a convex polygon whose angles are all congruent.The number of lines of symmetry in a regular polygon is equal to the number of sides a regular polygon has.
therefore
the answer is option B. n
Answer:
Therefore after 3 years the height of these tree will be same.
Step-by-step explanation:
Given that,
Type A is 2 feet tall and grows at a rate of 17 inches.
Type B is 10 feet tall and is growing at a rate of 5 inches.
1 feet = 12 inches,
2 feet= (12×2) inches = 24 inches
5 feet= (12×5) inches = 60 inches
Let after t years, the height of these tree will be same.
After t years, the height of type A is =(24+17t)
After t years, the height of type B is =(60+5t)
According to the problem,
24+17t=60+5t
⇒17t-5t=60-24
⇒12t = 36
⇒t = 
⇒t=3
Therefore after 3 years the height of these tree will be same.
Answer:
Length = 12 meters
Step-by-step explanation:
Rectangle
Perimeter P = 2(L + W)
The length of a rectangle, I, is six meters more than it's width, W.
Then L = W + 6
So
P = 2(W + 6 + W)
P = 2 (2W + 6)
P = 4W + 12
Plug in P = 36 meters
36 = 4W + 12
4W = 36 - 12
4W = 24
W = 6 meters
L = 6 + 6
L = 12 meters
Answer:
24
Step-by-step explanation:
Let total number of the chocolates be x.
25% of x = 6 (because 100 - 75 = 25% of chocolates left).
25/100 x x = 6
x = 600/25
x = 24
Hence, 24 is the total amount of chocolates.

You can solve this using trigonometric functions.
The angle between the fish and the ground is
tan θ = 100 / 50
θ = tan-1 (2)
θ = 63.43°
The height of the bird before it dropped the fish is already given, which is 100 yards.
