12 People fit comfortably in a 5 feet by 11 feet area. Use this value to estimate the size of a crowd that
is 10 feet deep on both sides of the street along a 3-mile section of a parade route.
Answer:
Step-by-step explanation:
Assuming that there are no sidewalks or other obstructions, the estimated size of the crowd along a 3-mile section of the parade route would be approximately 3,780,400 people. This calculation is based on the assumption that people will be standing shoulder to shoulder and that each person will take up an area of 5 feet by 11 feet. This would mean that for each mile of the parade route, there would be 1,260,800 people standing (12 people x 10 feet x 5280 feet). Multiplying this by 3 gives us 3,780,400 people.
Answer:
12 people fitting in an area of 5*5 = 25 ft². Area of the street: 3 miles = 3*5280 ft = 15840 ft 25 feet on both sides. So, the total area in which the crowd is sparsed is: A = 15840*25*2= 792000 ft². Now we apply the ratio: People over area. Applying cross multiplication: 25x = 12*792000 x = (12*792000)/25 x = 380160

domain: all real numbers range: y > 6
domain: all real numbers range: all real numbers
Domain and Range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively.
What are the domain and range?
The domain and range of a function are the set of all the inputs and outputs a function can give respectively. The domain and range are important aspects of a function. The domain takes all the possible input values from the set of real numbers and the range takes all the output values of the function.
We have the functions, f(x) = eˣ and g(x) = x+6
So, their composition will be g(f(x)).
Then, g(f(x)) = g(eˣ) = eˣ+6
Thus, g(f(x)) = eˣ+6.
Since the domain and range of f(x) = eˣ are all real numbers and positive real numbers respectively.
Moreover, the function g(f(x)) = eˣ+6 is the function f(x) translated up by 6 units.
Hence, the domain and range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively.

The sum of an A.P. is 340, the first term is 7 and the common difference is 6.
Calculate the number of terms in the sequence
The number of terms (n) in the sequence = 10.
We know that,
S = [tex]\frac{n}{2\\}[/tex] {2a + (n-1)d}
Where,
S = Sum of A. P. series
n = number of terms in A. P. series
a = first term of the series
d = common difference
According to the question,
Sum of the series, S = 340
First term, a = 7
Common difference, d = 6
S = [tex]\frac{n}{2\\}[/tex] {2a + (n-1)d}
340 = [tex]\frac{n}{2}[/tex] {2*7 + (n-1)6}
340 = [tex]\frac{n}{2}[/tex] {14 + 6n - 6}
340*2 = n( 6n + 8)
680 = 6n^2 + 8n
6n^2 + 8n - 680 = 0
2 (3n^2 +4n - 340) = 0
3n^2 +4n - 340 = 0
3n^2 + 34n - 30n - 340 = 0
n (3n+ 34) - 10 (3n + 34) = 0
(3n + 34) (n - 10) = 0
if we take, 3n + 34 = 0
3n = - 34
n = -34/3
which is not possible, as the number of terms can not be negative
if we take, n- 10 = 0
n = 10

Vanessa picked 12 strawberries. She divided the strawberries and gave 1/3 to her brother. She kept the rest for herself. How many strawberries did she give her brother.
Answer: 4 strawberries
Step-by-step explanation:
First, we can change the total number of strawberries into a fraction, that way it makes the division process easier. 12 is really equivalent to 12/1 since it is a whole number. Now, we can set up an equation: (12/1) * (1/3) will solve to give us the number of strawberries the brother has. Since there is a one in both the numerator and the denominator, they will cancel, leaving us with (12/3). This is now just division, which gives us 4. Therefore, the brother will receive 4 strawberries. Hope this helps!

A rectangle with sides of length 84 and 45 has the same perimeter asa hexagon. If the sides of the hexagon all have the same length then what is the length of a side of the hexagon
Ans:
The perimeter of a rectangle is given by 2length + 2width. In this case, the perimeter of the rectangle is 284 + 245 = 258.
Since the perimeter of the hexagon is the same as the rectangle, and the sides of the hexagon are all the same length, we can find the length of a side of the hexagon by dividing the perimeter by the number of sides.
A hexagon has 6 sides, so the length of a side of the hexagon is 258/6 = 43.
So the answer is (C) 43.
A square has an area of 25. Two opposite side of the square each have their length tripled what is the perimeter of the new figure.

A rectangle measures 6 centimeters by 25 centimeters the probability that a point randomly chosen inside the rectangle is closer to a side of length 25 than a side of length 6 is p/q are relatively prime positive whole numbers what is the sum of p and q.
Ans:
The probability that a point randomly chosen inside the rectangle is closer to a side of length 25 than a side of length 6 can be found by comparing the areas of the two triangular regions formed by the point and the two sides. The area of the triangular region formed by the point and the side of length 25 is (1/2) * 6 * (distance from point to side of length 25) while the area of the triangular region formed by the point and the side of length 6 is (1/2) * 25 * (distance from point to side of length 6).
For the point to be closer to the side of length 25, the area of the triangular region formed by the point and the side of length 25 must be greater than the area of the triangular region formed by the point and the side of length 6. This means (1/2) * 6 * (distance from point to side of length 25) > (1/2) * 25 * (distance from point to side of length 6). Therefore, the probability that the point is closer to the side of length 25 is (1/2) * (6/25) = 3/25. The sum of p and q is 3 + 25 = 28.
Therefore, the answer is (C) 37.

Joshua drove 22 miles in 55 minutes. If he drove at a constant rate, how far did he travel in one hour?
On the double number line below, fill in the given values, then use multiplication to find the missing value. Enter your answers as fractions, whole numbers, or decimals.
If Joshua drove at a constant rate, he drove 24 miles in one hour since he could drive 22 miles in 55 minutes or 0.4 miles per minute (driving speed).
What is the speed?Joshua's driving speed is the quotient of the total distance and the time.
The quotient is the result of a division operation, where a numerator (distance) is divided by the denominator (time) to obtain the unit rate or constant rate.
This constant rate (speed) is multiplied by the time (one hour), according to the distance, time, and speed formula, to obtain the distance to be covered.
The distance covered in 55 minutes = 22 miles
Constant driving speed or rate = 0.4 miles per minute (22/55)
1 hour = 60 minutes
For one hour, the distance Joshua could cover = 24 miles (60 x 0.4)
Thus, we can assert that in one hour, Joshua traveled 24 miles, given his constant driving rate.

So g(-3) = -5
The correct solution to this question is as follows:
f(2)= -3 & g(-3)=-5
Step-by-step explanation:
[tex]f(x)=x^{2} -2x-3[/tex]
[tex]f(2)=2^{2} -2(2)-3[/tex]
[tex]f(2)=4 -4-3[/tex]
[tex]f(2)=-3[/tex]
[tex]g(x)=x-2[/tex]
[tex]g(-3)=-3-2[/tex]
[tex]g(-3)=-5[/tex]

In November 2018, the frequency tree shows us that 35 students aged 15 years old had part-time work.
That number 35 drops to 23 a year later in 2019. There are two reasons for this:
The student lost their job. They got fired or quit their job.The 15 year old student had a birthday and turned 16.Case (2) mentioned above only works if the student's birthday is before April 2019.
Which angle is vertical to 1?
Answer:
Have a good day!:)
Step-by-step explanation:
When two lines intersect at a point, they form two pairs of angles that do not share a side. These pairs are called vertical angles, and they always have the same measure. ∠1 and ∠3 are vertical angles. ∠2 and ∠4 are vertical angles.
