Answer:
<h2>there are 22 dimes</h2><h2>there are 44 nickles</h2><h2 />
Step-by-step explanation:
D be dimes and N be nickles
2 nickles as dime
nickle = 5 cents and dime =10 cents
N=2D
0.10 D + 0.05 (N)=4.4 substitute N=2D
0.10 D +0.05(2D)=4.4
0.10D+0.10D=4.4
0.20 D=4.4
D=4.4/0.2 = 22
<h2>there are 22 dimes</h2>
N=2D
N=2(22)
N=44
<h2>there are 44 nickles</h2>
check : 0.10(22)+0.05(44)= 4.4 (correct)
From the attached graphic:
e = c*h/wavelength therefore,
wavelength = c*h / e
wavelength = 299,792,458 * 6.62606957e-34 / 3.38x10^-19
wavelength = 5.8771e-7 meters
Since multiplying by 0.5 is the same as dividing by 2, the problem is described by the sentence
"Half the sum of a number and 40 equals 200"
