Answer:
yea I don't understand either kid, it's upside down.
Step-by-step explanation:
If I understand correctly, just substitute 15 for C in f = 1.8c + 32, then solve for F
-------------------
f=<span><span>(1.8)(15)</span>+<span>32
</span></span>------------
Simplify
f=<span><span><span>(1.8)</span><span>(15)</span></span>+<span>32
</span></span>f = 27 + 32
f = 59 is your answer
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
Answer:
Step-by-step explanation:
1.60
B=number of ticets sold before
a=number of tickets sold after
cost of a ticket=number of tickets times cost per ticket
beforecost=39.95b
aftercost=54.95a
total cost=925000
39.95b+54.95a=925000
total number tickets=20000
b+a=20000
we have
39.95b+54.95a=925000
b+a=20000
multiply second equation by -39.95 and add to first equatin
39.95b+54.95a=925000
<u>-39.95b-39.95a=-799000 +</u>
0b+15a=126000
15a=126000
divide bot sides by 15
a=8400
sub back
b+a=20000
b+8400=20000
minus 8400 both sides
b=11600
11,600 tickets sold before
8400 tickets sold after
