Answer:
≈ 66.5 m
Step-by-step explanation:
Using the sine ratio in the right triangle
sin12° = 
= 
( multiply both sides by 320 )
320 × sin12° = d , then
d ≈ 66.5 m ( to 1 dec. place )
52• is the correct because you can add the wrong number to your economic system
That would just be
66/24, as there is 24 minutes in a half
66/24=2.75 points
p = 2.75 points per min
Answer:
20 chairs
Step-by-step explanation:
Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which s represents the number of chairs, and we simply solve for s.
800 = 320 + 24s ... subtract both sides by 300
500 = 24s ... divide both sides by 24
20.83 = s
Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.
