The base of a pyramid ABCDE is rectangle ABCD with width CD = 15 cm. The apex of the pyramid, E, is directly above the center of the base point O. The angle between lateral face AABE and the base is 54° while the angle between lateral face ABCE and the base is 73°. Find the volume of the pyramid. Round your answer to the cm³ m P nearest m M
Answers
Answer:
4372 cm³
Step-by-step explanation:
You want the volume of a symmetrical right rectangular pyramid whose lateral faces make angles of 73° and 54° with the base, and whose short side is 15 cm.
HeightThe height of the pyramid can be found using the tangent relation. The distance from the center to the steep face is (15 cm)/2 = 7.5 cm. The height will satisfy ...
Tan = Opposite/Adjacent
tan(73°) = height/(7.5 cm)
height = (7.5 cm)tan(73°) ≈ 24.5314 cm
SideA similar relation can be used to find the longer side length:
tan(54°) = height/(side/2)
side = 2·height/tan(54°) = (15 cm)tan(73°)/tan(54°) ≈ 35.6462 cm
VolumeThe volume is ...
V = 1/3Bh
V = 1/3(15 cm)(35.6462 cm)(24.5314 cm) ≈ 4372 cm³
The volume of the pyramid is about 4372 cm³.

A rectangular restaurant kitchen has an area of 80 square meters and a perimeter of 36 meters. What are the dimensions of the kitchen?
Answers
Answer:
Step-by-step explanation
Frist, the area = ab = 30 m^2 and the perimeter = 2(a + b) = 34 m or a + b = 17 m (2). Solving (1) and (2), a = 15 m and b = 2 m. Since it is a rectangle, the dimensions are (all in m) so the answer is: 15, 2, 15, 2.
Answer:
THe kitchen is 8 by 10
Step-by-step explanation:
x = width
y = length
Area = xy = 80 m²
Perimeter = 2x + 2y = 36 m
2x = 36 - 2y
x = 18 - y substitute into equation 1
(18 - y)(y) = 80
-y² + 18y - 80 = 0 find roots of y by factoring
y² - 18y + 80 = 0
(y - 8)(y - 10) = 0
y = 8, 10
Since xy = 80, then:
x = 80/10 = 8, or, x = 80/8 = 10
Now you have your dimensions: 8 and 10
To check the answers:
8 x 10 = 80 m²
2(8) + 2 (10) = 36 m

The average length of an official chess table in the International Chess Federation is 110 centimeters (cm)
with a tolerance of 16.5 cm. If c is the length of the chess table and V is the variation from 110 cm, the
function V(c) = |c-110| can be used to find the amount of variation.
Complete the statements by typing decimal values in the blank spaces.
Answers
Answer:
1. What is the maximum length of a chess table that is still within the tolerance limit?
To find the maximum length of a chess table that is still within the tolerance limit, we add the tolerance to the average length:
110 cm + 16.5 cm = 126.5 cm
Therefore, the maximum length of a chess table that is still within the tolerance limit is 126.5 cm.
2. What is the minimum length of a chess table that is still within the tolerance limit?
To find the minimum length of a chess table that is still within the tolerance limit, we subtract the tolerance from the average length:
110 cm - 16.5 cm = 93.5 cm
Therefore, the minimum length of a chess table that is still within the tolerance limit is 93.5 cm.

Step-by-step explanation:
The formula for area of triangle is
A = 1/2bh, where
A is the area in square units,b is the base,and h is the heightWe see from the diagram that the base is 6.2 cm and the height is 3.5 cm. Thus, we can plug these numbers in for b and h in the base formula to find the area, A:
A = 1/2(6.2)(3.5)
A = 1/2(21.70)
A = 10.85 square centimeters

Answers
Chase and Simon (1973) conducted a study on the memory of chess novices and experts for positions of chess pieces on a chessboard. They found that although experts generally have a better memory for chess positions than novices, novices performed equally or even better than experts when asked to recall random arrangements of chess pieces on the chessboard, even if the arrangements couldn't occur in a real game of chess.
One possible explanation for this phenomenon is that experts rely heavily on their knowledge of typical chess positions and patterns to remember the positions of the pieces. However, when the pieces are arranged randomly, these patterns are disrupted, and experts may struggle to apply their existing knowledge effectively. On the other hand, novices may not have developed strong patterns or strategies yet, so they approach the task with a more flexible mindset and are less affected by the random arrangement. They may use more general memory strategies, such as chunking or grouping the pieces together, which can be useful for recalling random arrangements.
In summary, novices may perform as well as experts when the pieces are arranged randomly because they rely less on established patterns and can use more general memory strategies to recall the positions.

The margin of error is 2.326 for the supplied values of c, σ, and n, which are 0.98, 0.78, and 150 respectively.
what is margin ?Margin is the term used to describe the equity that a trader has in their account. Using funds borrowed from a broker to buy stocks is referred to as "marging" or "buying on margin." Instead of a typical brokerage account, you must have a margin account to execute this. Beginning with your gross profit, which is the distinction between revenue and COGS, you may compute profit margin. Find the percentage of revenue that represents gross profit next. Calculate it by dividing your gross profit by your revenue. You can calculate your margin % by multiplying the sum by 100.
Given that,
Population standard deviation =
= 0.78
Sample size = n =150
α = 1 - 98% = 1 - 0.98 = 0.02
α= 2 = 0.02/ 2 = 0.01
Z*α = 2 = 0.01 = 2.326 ( Using z table )

< A = 47.8 < C = 84.2a = 120.6How to find the angels in triangle ABCThe angles in triangle ABC is calculated using the sine rule which sates that the ratio of a side and the opposite angles are equal to each other
This represented by the formula
Sine A / a = Sine B / b = Sine C / c
applying the formula for the problem
Sine B / b = Sine C / c
Sine 48 / 121 = Sine C / 162
cross multiplying
Sine C = 162 * Sine 48 / 121
Sine C = 0.99495
C = arc sine (0.99495)
C = 84.2
Applying sum of angles in a triangle
< A + < B + < C = 180
< A + 48 + 84.2 = 180
< A = 180 - 48 - 84.2
< A = 47.8 degrees
side a
Sine A / a = Sine B / b

The automobile

is an instrument that measures the speed of a vehicle. It has a circular
scale
that reads both miles per hour (mph) and kilometers per hour (km/h). To determine the
speed
in kilometers per hour, the user must first locate the needle on the scale. The needle should be pointing to a specific number that corresponds to both mph and km/h. For example, if the needle is pointing to 85, then the speed indicated in kilometers per hour is 85 km/h. It is important to note that if the needle is located between two
numbers
, the user should determine the approximate speed by interpolating the two numbers. To find the speed in miles per hour, the user can simply look at the number that corresponds to the needle on the scale. In this case, the speed indicated in miles per hour is 53 mph.
