If the statement is true, and you Rearrange it. It should still be true unless you added false facts into it.<span />
We know that
Inverse Variation is a<span> relationship between two variables in which the product is a constant
so
let
x------> a pitch of a musical instrument
y------> </span><span>the wavelength
x*y=k
find the value of k
for x=</span><span>220 hertz y=3 ft
</span><span>x*y=k
220*3=k
k=660
</span>for x=165 hertz y=4 ft
x*y=k
165*4=660
k=660<span>
the answer part a) is
</span><span>the type of variation between pitch and wavelength is an inverse variation
</span>
part b) <span>What is the pitch when the wavelength is 5 feet?
x=?
y=5 ft
k=660
x*y=k------> solve for x
x=k/y----------> x=660/5-----> x=132 hertz
the answer Part b) is
132 hertz</span>
Answer:
I think it is $156
Step-by-step explanation:
Multiply the numbers
Answer: Find the GCD (or HCF) of numerator and denominator. GCD of 70 and 20 is 10.
70 ÷ 1020 ÷ 10.
Reduced fraction: 72. Therefore, 70/20 simplified is 7/2.
