Answer:
The answer is 17.15! Brainliest pls :D
Using sin(A+B) = sinAcosB + cosAsinB
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree
=
A)
145 - 5d
5d = 145, set equal
29 days to lay all the track
b)
5*19 = 95
145-95 = 50
After 19 days, they have 50 miles to go.
the answer choices don't make sense but I can help u with solving the equation it's x = 1
- 3x-12=-9 , minus 12 on both sides
- 3x = 3 , divide 3 on both sides
- x = 1
now that u know this go through your answer choices and solve their equation and see which one produces x = 1 and that'll be the answer!!
Answer:
0.925m
Step-by-step explanation:
1.85m*12 = 22.2m used
2/3 = 22.2m <----- for gifts
3/3 = 33.3m <----- overall length of ribbons
33.3m - 22.2m = 11.1m
11.1m/12 = 0.925m
