A four-sided geometric object called a trapezoid has one pair of opposing sides that run parallel to one another. Its parallel sides are represented by its two bases, while its non-parallel sides are represented by its two legs. The lateral sides of the trapezoid are another name for the legs.
We must first locate the location of the trapezoid in order to determine where the grey patch of land will be after the 3 m walkway has been built. The following formula determines the area of trapezoid:
A = (b1 + b2)/2 * h
where h is the height, and b1 and b2 are the bases' lengths.
Inputting the values provided yields:
A is equal to (150m + 100m)/2 * 52m, or 125m * 52m, or 6500m2[tex]m^{2}[/tex].
After the walkway is built, the area of the grey piece of land is equal to the trapezoid's area minus the walkway's area. The walkway is 3 m by 52 m in size, or 156 [tex]m^{2}[/tex].
Therefore, 6500[tex]m^{2}[/tex] - 156[tex]m^{2}[/tex] = 6344[tex]m^{2}[/tex] is the area of the grey patch of land once the walkway is built.
So, the area of gray patche of land after construction of the walkway is 6344[tex]m^{2}[/tex].

Please help, my computer is about to die and this is due in a few minutes. Will mark brainlist if correct
Answer:
x = 1.5
Step-by-step explanation:
Here, we want to get what x is
To arrive at the answer for x, we are going to use an important circle theorem equation
We have this as;
lh^2 = lj * lk
from the question;
lh = 1
lj = 0.5
lk = (0.5 + x)
Thus;
1^2 = 0.5(0.5 + x)
1 = 0.25 + 0.5x
0.5x= 1-0.25
0.5x= 0.75
x = 0.75/0.5
x = 1.5

Nate downloaded a free virus detection program, which reported that his computer is infected with a virus. The editors of a tech magazine reviewed the effectiveness of the free program by running it on 500 computers, with 8% of those computers known to be virus-infected. Their findings are summarized in the two-way table. Virus Reported Virus not Reported Infected 28 12 Not Infected 94 366 Which statement is supported by the data? A. The magazine's review suggests Nate should trust the program's report because the probability that the scan result is a false positive is only 7.11%. B. The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 77.05%. C. The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 22.95%. D. The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 92.89%.
Answer: 77.05%
Step-by-step explanation:
.
The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 77.05%.
From the question we are told that:
Sample size n=500
Know Virus infection r=8\%
The data can be represented in the Table below a
[tex]\begin{tabular}{lllll}S/N & Reported & Not reported & Total \\Infected & 28 & 12 & 40 \\Not Infected & 28 & 36&460\\Total &122&378&500\\\end{table}[/tex]
Therefore the False Positive can be Mathematically represented as
[tex]FP=\frac{94}{122}[/tex]
[tex]FP=0.7705[/tex]
[tex]FP=77.05\%[/tex]
In conclusion we can say that The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 77.05%
Therefore

Urban rail systems have been proposed to alleviate traffic congestion, but results in many cities have been cited as evidence that this approach to traffic management is ineffective. For example, a U.S. city that opened three urban rail branches experienced a net decline of 3,100 urban rail commuters during a period when employment increased by 96,000. Officials who favor urban rail systems as a solution to traffic congestion have attempted to counter this argument by noting that commuting trips in that city represent just 20 percent of urban travel.
The response of the officials to the claim that urban rail systems are ineffective is most vulnerable to criticism on the grounds that it
A) presents no evidence to show that the statistics are incorrect
B) relies solely on general data about U.S. cities rather than data about the city in question
C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion
D) fails to show that the decline in the number of urban rail commuters in one U.S. city is typical of U.S. cities generally
E) provides no statistics on the use of urban rail systems by passengers other than commuters
Answer:
C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion
Step-by-step explanation:
The correct option is - C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion
Reason -
Option A is incorrect because the statistics can not be incorrect.
Option B is incorrect because they are not talking about the city.
Option C is correct because Urban rail reduces congestion.
Option D is incorrect because the opposers cited the example of one city and the supporters are presenting evidence in the case of that city itself.
Option E is incorrect because they are providing an explanation for why the commuters data given by opposers is not relevant. The opposers talked about commuters.

3(x+6)=24 I need help to find x
Answer:
[tex]\boxed{\bold{x \ = \ 2}}[/tex]Explanation:
3(x + 6) = 24
Simplify both sides of the equation3(x + 6) = 24
(3)(x) + (3)(6) = 24 (Distribute)
3x + 18 = 24
Subtract 18 from both sides3x + 18 − 18 = 24 − 18
3x = 6
Divide both sides by 33x / 3 = 6 / 3
[tex]\bold{x \ = \ 2}[/tex]Answer:
x = 2
Step-by-step explanation:
Remeber this rule: PEMDAS
Even though parantheses comes first, we must take away 3 By dividing (since 3 is currently multiplying with x+6). Picture it like a ‘tail,’ and you must take the tail away first. so it would look like this:
3 ÷ 3 (x+6) = 24÷3
3 ÷ 3 cancels out, and 24 ÷ 3 equals 8, so now your equation becomes:
x + 6 = 8
now, we subtract 6 (since it is adding with x)
x + 6 - 6 = 8 - 6
positive 6 and negative 6 (aka 6-6) cancel out, and 8 - 6 = 2, so x = 2

A magician showed a magic trick where he picked one card from a standard deck. Determined what the probability is that the card will be a red color or a queen card?
Answer:
7 / 13
Step-by-step explanation:
The number of cards in a standard deck = 52
Number of red cards in a deck = 26
Number of queens in a deck = 4
Selecting a card at random ;
Probability of picking a red card ;
P(red card) = number of red cards / number of cards in deck
P(red card) = 26 / 52
P(queens card) = number of queens / number of cards in deck
P(queens card) = 4 / 52
Number of red queen cards = (red n queen) = 2
P(red or queens card) = P(red) + P(queens) - P(red n queen)
P(red or queens card) = 26/52 + 4/52 - 2/52
= (26 + 4 - 2) / 52
= 28 /52
= 7 / 13

Solve for g. Make sure to use scrap paper to show your work.
( 144 + 6 x 8 ) ÷ 3 = g
Answer:
g=64
Step-by-step explanation:
(144+6×8)÷3=g
144+48/3=g
192/3=g
64=g
g=64
Answer:
g = 64
Step-by-step explanation:
(144 + 6 * 8) / 3 = g
g = (144 + 6 * 8) / 3
g = (144 + 48) / 3
g = 192 / 3
g = 64
