Since the waves are 0.15 apart and made by tapping the water surface twice each second the speed of waves in the puddle is 0.6 m/s
To answer the question, we need to know what a wave is
What is a wave?A wave is a disturbance in space which carries energy from one point to another
What is the speed of a wave?The speed of a wave v = fλ where
f = frequency and λ = wavelengthWavelength of waveSince the puddles are 0.15 m are and we know that this is the distance from crest to crest.
Also, the distance from crest to crest is λ/2
So, λ/2 = 0.15
λ = 2 × 0.15 m
= 0.3 m
Frequency of wave
Also, since the tapping by the water surface is done twice each second, the frequency, f = 2 times/s = 2 Hz
Speed of waves in puddleSubstituting the values of the variables into the equation, for speed, we have
v = fλ
v = 2 Hz × 0.3 m
v = 0.6 m/s
So, the speed of waves in the puddle is 0.6 m/s

solve 2(x-2) = 3(x+2)-8
Answer:
x = -2
Step-by-step explanation:
2(x-2) = 3(x+2)-8
Multiply the 2 and 3 out to the numbers in the parentheses. Don't multiply the 3 out to the -8 because it is outside of the parentheses.
2x-4 = 3x+6-8
Combine the 6 and -8
2x-4 = 3x-2
Subtract 2x from both sides
-4 = x-2
Add 2 to both sides
-2=x

Answer:
x = 25
Step-by-step explanation:

5x-2y ≤ 20 can you guys solve this.
Answer:
Step-by-step explanation:
Let's solve for x.
5x−2y≤20
Step 1: Add 2y to both sides.
5x−2y+2y≤20+2y
5x≤2y+20
Step 2: Divide both sides by 5.
5x /5 ≤ 2y+20 /5
x≤ 2 /5 y+4
Answer:
x≤ 2 /5 y+4
Let's solve for y.
5x−2y≤20
Step 1: Add -5x to both sides.
5x−2y+−5x≤20+−5x
−2y≤−5x+20
Step 2: Divide both sides by -2.
−2y /−2 ≤ −5x+20

3. You sell storm windows and doors. You receive a straight
commission of 8% of the selling price of each storm window
and 12% of the selling price of each door. What total
commission will you receive for selling $5,400 in storm
windows and $28,790 in doors?
Answer:
[tex]\$3886.8[/tex]
Step-by-step explanation:
Commission received on selling each storm window [tex]=8\%[/tex] of the selling price of each storm window
Commission received on selling each door [tex]=12\%[/tex] of the selling price of each door
Amount earned on selling storm windows = $5,400
Amount earned on selling doors = $28,790
Commission received on selling storm windows [tex]=\frac{8}{100}(5,400)=\$432[/tex]
Commission received on selling doors [tex]=\frac{12}{100}(28,790)=\$3454.8[/tex]
Therefore,
Total commission received [tex]=432+3454.8=\$3886.8[/tex]

an online store charges $5 to ship one box and $10 to ship two boxes. Write an explicit formula for an arithmetic sequence to represent the amount the online store charges to ship n boxes. Use the explicit formula to determine how much you online store charges when shipping 11 boxes.
Answer:
An explicit formula for the shipping cost is = . The store charges $55 when shipping 11 items.
Step-by-step explanation:
An online store charges when shipping 11 boxes would be; 55 dollars
What is an arithmetic sequence?An arithmetic sequence is a sequence of integers with their adjacent terms differing with one common difference.
An arithmetic sequence, therefore, is defined by two parameters, viz. the starting term, and the common difference.
Given that the online store charges $5 to ship one box and $10 to ship two boxes.
We have to write an explicit formula for an arithmetic sequence to represent the amount the online store pays to ship n boxes.
From what we know so far;
y = 5n
Now Using the explicit formula to determine how much the online store charges when shipping 11 items.
y = 5(11)
y = 55 dollars
Hence, A online store charges when shipping 11 boxes would be; 55 dollars
