Answer:
Frequency = 8 Hz ; Period = 0.125 s
Step-by-step explanation:
The amplitude of a wave is simply regarded as the maximum displacement experienced by a vibrating both from its equlibrum position.
The Displacement marked A in th picture is tbe Amplitude of the wave
The wavelength refers to the a complete cycle moved by a wave, that is the distance from a crest to another (maximum upward Displacement) or a trough to another (maximum downward Displacement).
2.)
Given that :
Velocity (V) of wave = 20 m/s
Wavelength (λ) = 2.5 m
The frequency (f) of the wave ;
f = v /λ
f = (20 m/s) ÷ 2.5m
f = 8 Hz
The period T of the wave :
T = 1 /f
T = 1 / 8
T = 0.125 seconds

Mrs. Nally's swimming pool is 10 feet by 6 feet. She paves the area around it with a sidewalk x feet wide, using 80 square feet of a new type of non-slip concrete. How wide is the sidewalk? A. The sidewalk is 20 feet wide. B. The sidewalk is 4 feet wide. C. The sidewalk is 10 feet wide. D. The sidewalk is 2 feet wide.
Answers
Answer:
The sidewalk is 2 feet wide
Step-by-step explanation:
The area of the sidewalk is given as 80 square feet
The length and width of pool
including side walks will be;
10 + 2x and 6 + 2x
To get the area of the side walk
That will be area of total minus area of the pool
That will be ;
(10 + 2x)(6 + 2x) - 10(6) = 80
60 + 12x + 20x + 4x^2 - 60 = 80
4x^2 + 32x -80 = 0
x^2 + 8x -20
x^2 + 10x - 2x - 20 = 0
x(x + 10) -2(x + 10) = 0
(x-2)(x + 10) = 0
x = 2 or -10
since width cannot be negative;
The sidewalk is 2 feet wide

Answers
Miami gets 6.12 more inches of rain.
What is mean by Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
We have to given that;
The average rainfall in inches in Miami from January to May is 1.61, 2.24, 2.99, 3.15, 5.35, and 9.68
While it is 2.24, 2.8, 3.03, 2.05, 2.09, and 6.69 during the same period in Tampa.
Hence, For Miami;
= 1.61 + 2.24 + 2.99 + 3.15 + 5.35 +9.68
= 25.02
For Tampa;
= 2.24 + 2.8 + 3.03 + 2.05 + 2.09 + 6.69
= 18.90
Thus, Find difference as;
= 25.02 - 18.90
= 6.12
Therefore, Miami gets 6.12 more inches of rain.

(Angles in a triangle add up to 180 degrees.)
Answers
Answer:
Angle A = 102°
Angle B = 51°
Angle C = 27°
Step-by-step explanation:
angle A = 2b
angle B = b
angle C = 1/3 b + 10
Angle A + Angle B + Angle C = 180
2b + b + 1/3 b + 10 = 180
3 1/3 b + 10 = 180
10/3 b = 170
b = 51
a = 2b = 102
c = 1/3 b + 10 = 1/3 (51) + 10 = 17 + 10 = 27

∠ WXU = 56°
Step-by-step explanation:
Since WX is a midline then WX and TV are parallel lines, thus
∠ WXU and ∠ TVX are corresponding and congruent, then
8x + 24 = 60 - x ( add x to both sides )
9x + 24 = 60 ( subtract 24 from both sides )
9x = 36 ( divide both sides by 9 )
x = 4
Thus
∠ WXU = 60 - x = 60 - 4 = 56°

Answer:
The coordinates are (-5,5)
Step-by-step explanation:
Here, we want to find the coordinates that divides the given line segment using the given ratio
Mathematically, the equation to use is the internal division formula
That will be;
(x,y) = (nx1 + mx2)/m + n , (ny1 + my2)/m + n
where m = 1
n = 4
(x1,y1) = ((-8,8)
(x2,y2) = (7,-7)
Substituting these values, we have
(x,y) = (4(-8) + 1(7))/(1+4) , (4(8) + 1(-7)/(1 + 4)
(x,y) = (-32 + 7)/5, (32 -7)/5
(x,y) = (-25/5), (25/5)
(x,y) = (-5,5)
