Add up all of the sides and you should get 13.
3 + 3 + 3.5 + 3.5 = 13
Frequency (f) in Hz = Wave speed (c) in m/s/Wavelength in m
Wave speed = 60 m/s, Wavelength = 1.2 m
Therefore,
f= 60/1.2 = 50 Hz
Answer:
false
Step-by-step explanation:
Number of green beans John should use is 30
<em><u>Solution:</u></em>
Given that ratio of pumpkin to green beans is 5 to 2
pumpkin : green beans = 5 : 2
Let "5a" be the number of canned pumpkins
Let "2a" be the number of canned green beans
John wants to use a total of 105 cans
number of canned pumpkins + number of canned green beans = 105
5a + 2a = 105
7a = 105
<h3>a = 15</h3>
number of canned green beans = 2a = 2(15) = 30
Thus number of green beans John should use is 30
