Answer:
$11.57
Step-by-step explanation:
First, find the total amount they need to pay.
Add the bill for lunch and the tip amount.
bill + tip
The bill was $29.46 and the tip was $5.25
$29.46 + $5.25
$34.71
The total amount with tip is $34.71
Next, find the amount each person should pay.
They want to divide the amount equally. There are 3 total people ( Jack + 2 friends = 3 people). Divide the total ($34.71) by 3.
$34.71 /3
$11.57
Each person should pay $11.57

Step-by-step explanation:
Component of the plane's velocity in the direction of vector relative to the air: ;
Component of the plane's velocity in the direction of vector relative to the air: .
The direction of the plane's velocity relative to the air is normal to vector . Therefore, the component of the plane's velocity (relative to the air) in that direction will equal zero. Thus
.
Refer to the second diagram,
Component of the velocity of the wind in the direction of vector : ;
Component of the velocity of the wind in the direction of vector : .
Assume that the wind blows horizontally. The direction of the wind will be normal to vector . The component of the velocity of the wind in the direction of vector will thus equal zero. Therefore,
.
The ground speed of the plane is the sum of and .

Answer:





Step-by-step explanation:
Given that:
is an angle in a right angled triangle.
and 
To find:
To draw the triangle and write other five trigonometric functions in terms of C.
Solution:
We know that cosine of an angle is given by the formula:

Here, we are given that
OR

i.e. Base = C and Hypotenuse of triangle = 1
Please refer to the right angled triangle as per given statements.
, with base PR = C units
and hypotenuse, QP = 1 unit
is the right angle.
Let us use pythagorean theorem to find the value of perpendicular.
According to pythagorean theorem:







Answer:
Bisect the segment that is the sum of the given segments
Step-by-step explanation:
You want to construct a line segment whose length is the average of two given line segments.
<h3>Solution</h3>
You know that the average of two lengths is half their sum. To construct a line that is half the sum ...
- Construct a segment equal to the sum. For example, from point X on a line, mark XY = AB to the left of X, and XZ = CD to the right of X. Segment YZ will be the sum of AB and CD.
- Bisect it. Draw arcs above and below YZ with the same radius equal to more than half of YZ. The line through the intersection points of each pair of arcs will be the perpendicular bisector of YZ. If it intersects YZ at Q, then YQ = QZ = average of AB and CD.
