Answer:

Step-by-step explanation:

Let width be x

So length would be x + 9

If perimeter is 86, then

2(l+b) = 86

2(x + x+9) = 86

4x + 18 = 86

4x = 68

X = 17

Check:

2(x + x + 9) = 86

2(17 + 17 + 9) = 86

2(43) = 86

86 = 86

Here you go

string length is 0.5m and the wavelengths are 0.25meters. This tells us there are two complete waves in the guitar string. This gives us a total of four antinodes; thus we are in the fourth harmonic.

dlinn [17]
Given that there are 10 children who own a dog, and 14 children who do not, the ratio of the children that owns a dog to the children that do not own a dog, is 10:14.

To express the ratio in a simplify fraction, we will just use fractional notation.  Thus, it is simply 10/14, or 5/7 as its simplest form.
