All but two of the here amid’s built by the ancient Egyptians have faces inclined at 52° angles. Suppose an archaeologist discovers the ruins of a pyramid. Most of the pyramid has eroded, but the length of a side of the square base is 82 m. How tall was the pyramid, assuming it’s faces were inclined at 52°? Round your answer to the nearest meter.
A) 25m
B) 32m
C)52m
D) 105m
Answers
One of its sides is the height of the pyramid, with length H. The other side is half of the square base, so its length is 81 m. The hypotenuse of this triangle is the height of one of the faces.
By right triangle trigonometry,
[tex]\displaystyle{ \tan52^o= \frac{H}{41 \ m } [/tex],
thus,
[tex]H=\tan52^o\cdot41 \ m=1.28 \cdot41 \ m=52 \ m[/tex].
Answer: C) 52 m

What system of linear inequalities is shown in the graph?
Enter your answers in the boxes.

Answers
We know that, since it is a dotted line, it is an inequality (< or >, rather than ≤ or ≥). We also see that the area under this line is shaded, so it is a less-than inequality:
y < mx + b, where m is the slope and b is the y-intercept.
The slope is -3, since the line moves down 3 and over 1
The y-intercept is 1
y < -3x + 1
For the second graph, we apply the same steps:
y ≥ mx + b
m = 1/2 (up one, over 2), b = -1
y ≥ (1/2)x -1

Charlotte buys tickets to go to a baseball game the total includes a charge of 7% of the original price for extra fees. If Charlotte pays a total of $44.94 how much was the original price of the ticket
Answers
The original price of the ticket is $42.
Let the original cost of the ticket be represented by x
Based on the information given, the equation to solve the question will be:
x + (7% × x) = $44.94
x + (7/100 × x) = $44.94
x + (0.07 × x) = $44.94
x + 0.07x = $44.94
1.07x = $44.94
Divide both side by 1.07
1.07x/1.07 = $44.94/1.07
x = $42
Therefore, the original price of the ticket is $42.

https://brainly.com/question/1840547
The original price of the ticket was $42.
Explanation:To find the original price of the ticket, we need to subtract the extra fees from the total amount Charlotte paid.
Let x be the original price of the ticket.
The extra fees would be 7% of x, which is 0.07x. Since the total paid is $44.94, we can set up the equation:
x + 0.07x = 44.94
Combining like terms on the left side gives us 1.07x = 44.94.
Next, we divide both sides by 1.07 to isolate x:
x = 44.94 / 1.07 = $42
Therefore, the original price of the ticket was $42.

Carmen needs at least 86 points to pass Karissa's score. Karissa has 631 points. How many points does Carmen have?
Answers
Anywho, Let's figure this out.
631-86 = 544
So Carmen would technically have 544 points to have the same amount as Karissa. But, but, but, the question states that, "Carmen needs at least 86 points to pass Karissa..." So since Carmen has to pass Karissa's score we can say that she has 545 points rather than 544 because 545 + 86 = 632 which is one more point than Karissa's to "pass," her score.

slice every piece in the first pizza into 4 equal pieces
and every piece in the second pizza into 3 equal pieces.
Answer:
The first pan has to be divided into 4 equal parts.
The second pan has to be divided into 3 equal parts.
Step-by-step explanation:
The first step to solve this problem is finding the least common multiple of 6 and 8.
The multiples of 6 are {0,6,12,18,24,30,36,42,...}
The multiples of 8 are {0,8,16,24,32,...}
The least common multiple of 6 and 8 is 24.
So both kinds of pasta have to be baked so after the second step they have 24 equal parts.
So:
First pan:
The first pan was sliced into 6 equal parts.
24/6 = 4.
So each of the 6 parts have to be divided into 4 equal parts.
After the second step, they have 6*4 = 24 equal parts.
Second pan:
The second pan was sliced into 8 equal parts
24/8 = 3
So each of the 8 parts have to be divided into 3 equal parts.
After the second step, they have 8*3 = 24 equal parts.

C) 17.5°
D) 35°
Answers
The measure of arc CB, <CFB = 70°.
What is Arc?A circle's arc is referred to as a portion or section of its circumference. A chord of a circle is a straight line that might be created by joining the arc's two ends. A semicircular arc is one whose length is exactly half that of a circle.
Given:
First, Draw segment FC.
Measure of arc CB = ∠CFB
As, ∠CFB is complementary to ∠CFA
So, ∠CFB = 180° - ∠CFA
We have Δ CFA is isosceles then
∠ FAC = ∠ FCA = 35°
∠CFA +∠ FAC + ∠ FCA = 180°
∠CFA = 180° - 70°
∠CFB = 180° - (180° - 70°)
<CFB = 70°
Thus, the Measure of arc CB is 70°.

What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given the following details as shown below.
The agency charges $32.50 for each ticket, A convenience charge of $3.30 for each ticket And a processing fee of $5.90 for the entire order. The total charge for an order is $220.70.Let M represent the number of tickets purchased. Therefore, we can write,
Total charge = cost of each ticket x M + convenience charge x M + processing fee
220.70 = 32.50M + 3.30M + 5.90
Subtract 5.90 on both sides
220.70 - 5.90 = 32.50M + 3.30M
214.8 = 35.8M
Divide both sides by 35.8
6 = M
This means the number of tickets purchased is 6.
Thus, the number of tickets purchased is 6.

Answers
The type of reasoning demonstrated in the scenario is deductive reasoning.
Deductive reasoning starts with a general premise or statement and applies it to a specific case to reach a logical conclusion. In this case, the premise is that white chickens lay white eggs and colored chickens lay brown eggs. Therefore, when encountering a white chicken, the conclusion is drawn that it will lay white eggs.
To understand deductive reasoning, let's break it down:
Premise:
White chickens lay white eggs.
Colored chickens lay brown eggs.
Observation:
Encounter a white chicken.
Conclusion:
Therefore, the white chicken will lay white eggs.
This conclusion is based on the general premise about the egg-laying behavior of white and colored chickens. Deductive reasoning allows us to draw specific conclusions from general principles, assuming the premises are true.
Find the 80th percentile of the distribution of the average of 49 fly balls.
Answers
The 80th percentile of the distribution of the average of 49 fly balls is approximately 254.2 feet
The 80th percentile of the distribution of the average of 49 fly balls can be found using the formula for the sample mean and the Z-score. Given that the mean distance of fly balls hit is 250 feet, the standard deviation is 50 feet, and the sample size is 49, we can calculate the 80th percentile as follows:
Calculate the Z-score corresponding to the 80th percentile, which is 0.842
Use the Z-score formula to find the sample mean:
Sample Mean=Population Mean + Z × Standard Deviation/ Sample Size
Sample Mean=250+0.842× 50/ √49
Sample Mean=250+0.842×5
Sample Mean=250+4.2
Sample Mean=254.2
Therefore, the 80th percentile of the distribution of the average of 49 fly balls is approximately 254.2 feet
Complete question:

Answers
60-16=44
It is 4 times 15 because if there are 4 bike racks and each bike racks have 15 slots for bikes then you have to multiply the amount of slots with the amount of bike racks are available, then you must find out how many slots are left. To do this you must subtract the amount of bikes in the bike racks with the total amount of slots. This will leave you with 44 slots available.
