light is gathered from a distant galaxy and one of the spectral lines of calcium is observed at 413.26 nm when it should be 393.37 nm.
(a) find the velocity of this galaxy (hint: doppler formula).
(b) find the distance to this galaxy (hint: hubble law).
note: be sure to always use the formula sheet.
14,786 km/s, 205 mpc

answer: 193

explanation:

200-7 = 193

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

60 for the first and 130 for the second
