Answer: 1.2 miles
You can find the answer by using the pythagorean theorem.
a^2 + b^2 = c^2.
(5000)^2 + (4000)^2 = c^2
25 million +16 million = c^2
41 million = c^2
Take the square root of both sides in order to get the value of C.
C = about 6,403 feet.
1 mile = 5280 feet
6403/5280 = 1.2

The list of the digits is: { 1, 2, 2, 3, 4, 5, 6 }
Here we have to determine how many ways are there to list the digits { 1, 2, 2, 3, 4, 5, 6 } so that identical digits are not in consecutive positions
We have one number in consecutive positions in this question
That is: (2, 2)
Number of ways that (2,2) are in consecutive positions = [tex]$\frac{6!}{2!}[/tex] = 360
The permutation of 1, (2, 2), 3, 4, 5, 6 = 6!
6! = 720
To get the total number of permutations

The graphs shows the speed of a car for 30 seconds. A) using a single appropriate trapezium , estimate the distance travelled by the car during this time . B) is your answer an overestimate or underestimate ?
The distance travelled by the car during this time by using single appropriate trapezium is 26.25 and the answer provided is an underestimate
Estimate the distance travelled by the car during this time?A) Using a single appropriate trapezium, the estimated distance travelled by the car during the 30 seconds is approximately 55 metres.
This is calculated by taking the area of the trapezium formed by the two points of the speed graph: 8m/s and 6m/s.
The area is calculated by taking the average of the two points, multiplied by the time duration:
Area = (8+6/2) * 30
Area = 7*30
Area = 210
The area of the trapezium is then divided by the speed of the car at the start of the journey (8m/s) to get the estimated distance travelled:
Distance = 210/8
Distance = 26.25
This is rounded up to give an estimated distance travelled of 55 metres.
B) The answer of 55 metres is an underestimate of the actual distance travelled by the car. This is because the trapezium method only takes into account the start and end points of the graph, and not any of the other points in between. The actual distance travelled by the car is likely to be higher as the speed of the car is likely to have been greater at points in between the start and end points.

El departamento de teatro de la escuela está organizando una producción y planea cobrar $10 por entrada y $5 por una entrada para niños. Necesitan ganar por lo menos $3,000 cada noche para cov s. El auditorio tiene capacidad para 400 personas.
The four inequalities are a + c ≤ 400, 10a + 5c ≥ 3000, a ≥ 0 and c ≥ 0. The club must sell 200 children tickets and 200 adult tickets.
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.
The value for one ticket is - $10
The value for one children's ticket is - $5
The total amount that need s to be earned is - $3000
The number of seats in the auditorium is - 400
Let the number of children be = c and the number of adults be = a.
Then the inequality will be -
a + c ≤ 400
10a + 5c ≥ 3000
a ≥ 0
c ≥ 0
The inequalities will have a straight line as (≤,≥) symbols are used in the inequalities.
Write the two inequalities in equation form -
a + c = 400....(1)
10a + 5c = 3000 or 2a + c = 600....(2)
Subtract equation (1) from (2) -
2a + c - (a + c) = 600 - 400
2a + c - a - c = 200
a = 200
a = 200
Substitute the value of a in equation (1) -
200 + c = 400
c = 400 - 200
c = 200
So, the intersection point is (200,200) and the number of children is 200 whereas the number of adults is 200.
Therefore, the graph is obtained.

Mrs. Cooper paid more than $22 for a pack of hand towels. Each towel cost $2.85. The hand towels were available in packs of 4, 5, 6, and 8. Use the inequality to find the minimum number of towels, t, in the pack.
Using inequality, the minimum number of towels in the pack is t = 6.
How to Find Minimum Number Using Inequality?We can start by using the inequality 2.85t > 22, where t is the number of towels in the pack.
To find the minimum number of towels, we can use the smallest possible value for t that satisfies the inequality. Since the hand towels were available in packs of 4, 5, 6, and 8, we can use t = 4 in the inequality:
2.85(4) > 22
Simplifying the left side of the inequality gives:
11.4 > 22
This is not true, so t = 4 does not satisfy the inequality.
Next, we can use t = 5:
2.85(5) > 22
Simplifying the left side of the inequality gives:
14.25 > 22
This is also not true, so t = 5 does not satisfy the inequality.
We can keep doing this for t = 6, and t = 8, we will find out t=6 is the minimum value of t that satisfies the inequality.
2.85(6) > 22
Simplifying the left side of the inequality gives:
17.1 > 22
This is true, so t = 6 is the minimum number of towels in the pack.

The amount of chlorine in the tank as a function of time is:
C(t) = 0.05 * e^(-6/400*t)
Let C(t) be the concentration of chlorine in the tank at time t and V(t) be the volume of the tank at time t.
At t=0, we know that:
C(0) = 0.05 g/l
V(0) = 400 l
As fresh water is pumped in at a rate of 4 l/s and the mixture is pumped out at a rate of 10 l/s, the rate of change of the volume of the tank is:
dV/dt = 4 - 10 = -6 l/s
As the concentration of chlorine is being diluted by the addition of fresh water, the rate of change of the concentration is proportional to the rate of change of the volume. So we can write:
dC/dt = - k * C(t) * (dV/dt)
where k is a proportionality constant.
We can integrate the above equation with respect to time to find the concentration of chlorine in the tank as a function of time:
C(t) = C(0) * e^(-kt)
In order to find the value of k we can use the initial condition C(0) = 0.05 g/l and V(0) = 400l
0.05 = C(0) * e^(-k*0)
0.05 = C(0)
so we can substitute this value into the above equation and solving for k:
C(0) = 0.05 = 0.05 * e^(-k*0)
0.05 = 0.05
so k = -6/400
Finally, the amount of chlorine in the tank as a function of time is:
C(t) = 0.05 * e^(-6/400*t)
This equation expresses the amount of chlorine in the tank as a function of time t. As time goes on, the concentration of chlorine will decrease exponentially.
