First, you need to remember how to obtain the answer.
1) (velocity)*(cosine of the angle)2)(velocity)*(sine of the angle)
Since the plane is traveling 45 degrees below the horizon the angle that we will be using is 180+45=225.
Therefore we will have,
150* cos(225) = -81.31
150*sin(225) = -81.31
*In the unit circle, the coordinates of 225 are -squareroot(2) divided by 2 for both sin and cos, which explains why we have the same answer for both sin and cos.
The answer being negative makes sense since the speed is decreasing due to the fact that the plane is traveling below horizontal.
Using the Law of Sines (sinA/a=sinB/b=sinC/c) and the fact that all triangles have a sum of 180° for their angles.
The third angle is C is 180-53-17=110°
27/sin53=b/sin17=c/sin110
b=27sin17/sin53, c=27sin110/sin53
And the perimeter is a+b+c so
p=27+27sin17/sin53+27sin110/sin53 units
p≈68.65 units (to nearest hundredth of a unit)
Answer:
Bill's bar has 57.3 grams of cocoa.
Step-by-step explanation:
The math part that your question is asking is: What is 69% of 83?
In order to use the percent 69% in a calculation, you need to change it to a decimal.
69% is 0.69
You move the decimal to the left, two places.
69% is 69.% If you don't see a decimal to start with and it is a whole number, then the decimal is starting on the right.
Move it two places to the left, you get
.69
Now MULTIPLY.
.69 × 83
= 57.27
ROUND your answer to the nearest tenth. That means only one digit to the right of the decimal.
57.27 rounds to 57.3
