40+80=120. 40/120=.3333.... or 1/3. so sandwiches percent is 33% and so 100-33= 67 so the bottles of water would be 67%
Answer:
The equation 7h=63 can be used to find how many hours h a person needs to work to earn $63 at $7 per hour. How many hours does a person need to work to earn $63?
Step-by-step explanation:
The equation 7h=63 can be used to find how many hours h a person needs to work to earn $63 at $7 per hour. How many hours does a person need to work to earn $63?
Refer to the diagram shown below.
m∠A = 120°
b = 13 cm
c = 15 cm
From the Law of Sines, the area of the triangle is
Area = (1/2)*b*c*sin(A)
= 0.5*13*15*sin(120°)
= 84.4375 cm²
Answer: 84.4 cm² (nearest tenth)
