Answer:
(3/2, 6)
Step-by-step explanation:
y = 4x
8x + y = 18
this says y is 4x so you can replace y with 4x
8x + 4x = 18
12x = 18
/12 /12
x = 3/2
now sub x into y = 4(3/2)
y = 12/2
y = 6
You gave us the speed and the frequency, and you need the wavelength.
You were also nice enough to remind us that (fqy)x(lng) = speed.
So . . . F x W = 343 m/s
Divide each side by F :
W = (343 m/s) / F
W = (343 m/s) / (240 / s)
W = (343/240) m
<em>W = 1.429 meters</em>
Expand the right side:
Notice that 98 = 2 * 7 * 7, so we have 
and 
.
Then
and
Answer: 11x1.5=16.5 if im correct
Step-by-step explanation:B)
There are many shapes of a star. It depends on the shape of the star. If you’re referring to this star, then the number of triangles is 5.
Hope this answers your question!
