Step-by-step explanation:
Height of Mount Everest = 8.8 x 10³ m = 8800 m
Height of the Empire State Building = 3.8 x 10² m = 380 m
[tex]\frac{\texttt{Height of Mount Everest}}{\texttt{Height of the Empire State Building}}=\frac{8800}{380}\\\\\frac{\texttt{Height of Mount Everest}}{\texttt{Height of the Empire State Building}}=23.16[/tex]
Height of Mount Everest = 23 x Height of the Empire State Building.
So, Mount Everest is about 23 times as tall as the Empire State Building

A bridge in the shape of an arch connects two cities separated by a river. The two ends of the bridge are located at (–7, –13) and (7, –13), and the center of the arch on the bridge is located at (0, 0). Find the equation of the arch of the bridge.
The equation of the arch is y = (-13/49)x².
The equation of an arch can be described by a parabola when one side of the arch mirrors the other side. This is the case for the bridge problem given.
The center of the bridge is at the origin (0, 0), and it is the vertex of the parabola. Since the arch is symmetrical and the x-coordinate of the vertex is 0, the parabola is a vertical one. Thus, the equation will be in the form y = ax². To find the value of a, we will use the fact that one end of the bridge is at (7, -13).
Since (7, -13) is a point on the parabola, by plugging these values into the equation y = ax², we get:
-13 = a(7²)
-13 = 49a
a = -13/49
Thus, the equation is y = (-13/49)x².

There is a traffic light at the intersection of walnut street and Lawrence avenue. The traffic light in walnut street follows a cycle. It is green for 50 seconds, yellow for 10 seconds, and red for 30 seconds, as you travel along walnut and approach the intersection, what is the probability that the first color you see is red?
Answer: The probability that the first color we see is red is 0.34.
Step-by-step explanation:
Since we have given that
Time taken by green color on the traffic light = 50 seconds
Time taken by yellow color on the traffic light = 10 seconds
Time taken by red color on the traffic light = 30 seconds
Total number of seconds = 50+10+30=90
So, Probability that the first color we see is red is given by
[tex]\dfrac{\text{Time alloted for red color}}{\text{Total number of seconds}}\\\\=\dfrac{30}{90}\\\\=\dfrac{1}{3}\\\\=0.3333...\\\\\approx 0.34[/tex]
Hence, the probability that the first color we see is red is 0.34.
Solve the inequality. 8x-5>_27. A.x>_4. B.x>_11/4. C.x<_4. D.x<_11/4
The solution for the inequality 8x - 5 ≥ 27 can be written as x [4, ∞) or x ≥ 4, so option A is correct.
What is inequality?An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.
Given:
8x - 5 ≥ 27
Solve the above inequality as shown below,
Add 5 to both sides of an inequality,
8x - 5 + 5 ≥ 27 + 5
8x ≥ 32
Divide both sides by 8,
8x / 8 ≥ 32 / 8
x ≥ 4
x [4, ∞)
Thus, x can be any real number greater than 4 or equal to four.

Step-by-step explanation:
From the figure, since RT is parallel to QU, therefore ΔSQU is similar to ΔSRT, thus using the basic proportionality theorem, we get
[tex]\frac{SR}{SQ}=\frac{ST}{SU}[/tex]
[tex]\frac{c}{12+c}=\frac{10}{25}[/tex]
[tex]25c=120+10c[/tex]
[tex]15c=120[/tex]
[tex]c=8[/tex]
Also, QU is parallel to PV, therefore from ΔPVS and ΔSRT, we have
[tex]\frac{SR}{SP}=\frac{ST}{SV}[/tex]
[tex]\frac{c}{c+12+d}=\frac{10}{30}[/tex]
[tex]\frac{8}{20+d}=\frac{1}{3}[/tex]
[tex]24=20+d[/tex]
[tex]d=4[/tex]
Now, from ΔSRT and SQU, we have
[tex]\frac{RT}{QU}=\frac{ST}{SU}[/tex]
[tex]b=\frac{10{\times}12.5}{25}[/tex]
[tex]b=5[/tex]
Also, from ΔSQU and SPV,
[tex]\frac{12.5}{a}=\frac{25}{30}[/tex]
[tex]a=15[/tex]
Thus, value of a,b,c and d are 15,5,8 and 4 respectively.
A small school has 110 students who occupy three classrooms: a, b, and
c. after the first period of the school day, half the students in room a move to room b, one-fifth of the students in room b move to room c, and one-third of the students in room c move to room
a. nevertheless, the total number of students in each room is the same for both periods. how many students occupy each room?
There are 20, 50 and 30 in each room respectively.
What is equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, there are 110 students in total in all the class.
According to question,
a+b+c = 110
After the room changes, we have
a/2 + c/3 = a
4b/5 + a/2 = b
2c/3 + b/5 = c
or,
a/2 = c/3
a/2 = b/5
b/5 = c/3 = a/2
so, substituting in,
a + 5a/2 + 3a/2 = 110
2a + 5a + 3a = 220
a = 22
b = 55
c = 35
Hence, there are 20, 50 and 30 in each room respectively.

What is the data path width for a dimm that supports ecc?
Normally, the data path width for DIMMs is 64 bits but for the DIMMs that support ECC, the data path is 72 bits.
To add, error checking uses the extra 8 bits. ECC memory is more reliable than non-ECC memory but it costs more than a non-ECC memory. Comprising the DIMMS are a series of dynamic random-access memory integrated circuits. Mounted on a printed circuit board, these modules are designed for use in personal computers, workstations and servers.
The most common kinds of internal data corruption are detected and corrected by a type of computer data storage called error-correcting code memory.

Suppose that 66% of people own dogs. if you pick two people at random, what is the probability that they both own a dog?
The probability of two people owning a dog when 66% of people own dogs is found by squaring the probability (0.66), giving us a result of 0.4356 or 43.56%.
Explanation:The question asks to calculate the probability that both people picked at random own a dog when it is known that 66% of people own dogs. To find this probability, we can simply multiply the probability of the first person owning a dog by the probability of the second person owning a dog, assuming that these events are independent.
The probability that one person owns a dog is given as 66%, which is 0.66 in decimal form. Thus, the probability that both people own a dog is 0.66 × 0.66 (or 0.66 squared). Calculation yields:
0.66 × 0.66 = 0.4356
Therefore, the probability that both people own a dog is 0.4356, or 43.56%.
