B. c = ((3)sin45°)/sin40°
Side a is given information: 3cm, and we can find angle A (which is the angle opposite side a) by subtracting the other two angles from 180 because the total interior angle measures of a triangle add to equal 180°.
Angle A = 180 - (95+45) = 40°.
This can be substituted into the equation for the law of sines.
sin(40)°/3 = sin(45)°/c
—Cross multiply
c•sin(40)° = 3•sin(45)°
—divide both sides by sin40 to get the variable c alone and we get:
c = (3)sin(45°)/sin(40°)
this also simplifies to 3.3 cm.
Answer:
27
Step-by-step explanation:
Each foot of rope can make 3 pieces of 1/3 feet length
1 feet of rope = 3 pieces
There are 9 feet of rope
3 pieces x 9 feet = 27 pieces
So you can make 27 pieces
If y decreases as x increases, we are looking for a negative slope. The r = -0.87 tells us that the data points correlate relatively well. The closer the decimal is to 1 or -1, the better. The answer is A.
Timeperday=time/day=1095/365=3/1=3
answer is 3 hours per day
