At a restaurant, you decide to order the lunch special that includes one entree, one side and one drink. There are 5 entrees to choose from, 6 sides to choose from and 7 drinks to choose from. How many total options are there when ordering this meal?

   168

Step-by-step explanation:

Total entree = 6

Total slides = 4

Total drink = 7

Lunch special includes 1 entree, 1 slides, and one drink.

Option for entree

= 6_(c_1)

=6

Option for slides

= 4_(c_1)

=4

Option drinks

= 7_(c_1)

=7

So, total option ordering meal,

=6*4*7

=168

Hope this helps! :)

(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

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
