Answer:
Step-by-step explanation:
You need to remember the following:
1. The area of a rectangle can be calculated with the following formula:
Where "l" is the length and "w" is the width.
2. The area of a triangle can be calculated with the following formula:
Where "b" is the base and "h" is the height.
Use those formulas to find the area of each face.
<u> Area of the rectangle</u>
<u>Area of two triangles</u>
There are two equal triangles. Each one has a base of 10 inches and a height of 5 inches. Then, their areas are equal:
The areas of the other two triangles (which are equal) are:
Adding the areas of the faces, you get that the surface area of the rectangular pyramid is:
If i read this correctly then the answer would be
57-12= 45
45/9= 5
The answer is 5
Since the
total of weight of an exam is 100 and the final exam is 4 times the weekly exam
X + 4x =
100 %
5x = 100
%
X = 20%
4x = 80%
Weighted ave
= 0.2( ave weekly exam) + 0.8(final exam
88 =
0.2(92) + 0.8(final exam)
Solve for
the final exam

= 87</span>
Answer: 119°
Step-by-step explanation:
From the positive y-axis, all angles are measured clockwise
PR = PQ + QR = 5[150°] + 3[60°]
X = 5*sin150 + 3*sin60 = <u>5.1</u>
Y = 5*Cos150 + 3*Cos60 = <u>-2.83</u>
TanA = X/Y
A = -61° = 61° East of South = 119° Clockwise
Therefore, the bearing of R from P is 119°
