The Science Club went on a two-day field trip. The first day the members paid $30 for transportation plus $10 per ticket to the planetarium. The second day they paid $100 for transportation plus $7 per ticket to the geology museum. Write an expression to represent the total cost in dollars for two days for the n members of the club. An expression that represents the total cost in dollars for two days for the n members of the club is given by

just add all the numbers which means $147

I believe is $147 because u have to add all the number and it will give u the total of 147. So the total cost in dollars for two days for the n members of the cub will be $147.

answer: this doesnt make any sense especially the photo.

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
