Suppose the shorter leg is x, then the longer leg is x+3, and the hypotenuse is x+6
x^2 +(x+3)^2 =(x+6)^2
x^2 + x^2 + 6x +9=x^2 + 12x +36
x^2-6x-27=0
(x+3)(3-9)=0
x=-3, which is impossible, or x=9
so the shorter leg is 9mm, the longer leg is 12mm, and the hypotenuse is 15mm
Answer:
Step-by-step explanation: 15 minus 6.2 is 8.8 thats how much he needs to fill upp if it is 3.50 a gallon you would multiply to get 30.8 thats how much money he spent on gas
90+2 so 9 tens and 2 ones
10+10+10+10+10+10+10+10+10+10 = 9 tens or 90
1+1= 2 ones or 2
The pitch depends on the value of frequency. The frequency can be calculated using this formula:
Frequency = wave speed / wavelength
where wave speed = 343.00 m/s
wavelength = 0.77955 m
Frequency = 343.00 m/s / 0.77955 m
= 434.00 s^-1
Therefore the pitch is low since the frequency is also low.
