Length can be expressed as 2L + 2w = 26 since we know the total perimeter is 26 inches. Width can expressed as w = 3L - 15, since we know that it is 15 inches less than 3x the length. Then substitute the width into the length formula.
2L + 2w = 26
2L + 2(3L - 15) = 26
2L + 6L - 30 = 26
8L = 56
L = 56/8
L = 7 inches
Substitute 7 into the width formula to find width:
w = 3L - 15
w = 3 x 7 - 15
w = 6 inches
Finally use the area formula:
A = L x W
A = 7 x 6
A = 42 [tex]inches^{2}[/tex]
The distance Train A travels is represented by d = 69t, where d is the distance in kilometers and t is the time in hours. The distance Train B travels at various times is shown in the table. What is the unit rate of each train? Which train is going faster?
If d is distance measured in km and t is time measured in hours, then d = 69t tells you that train A is moving at a rate of 69 km/h.
Why? If t = 1, then d is the distance it moves in 1 hour, and that's precisely the unit rate. It's the rate at which the distance changes when 1 unit of time passes.
For train B, use the info in the given table. In 1 hour (between hours 4 and 5), the train covers a distance of 375 km - 300 km = 75 km. So it's moving at a rate of 75 km/h.
It should be clear which train is faster.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]d(A) = 69t[/tex]
[tex]d(B) = 75t[/tex]
The unit rate is the coefficient of t which is the slope of the line because the trains distance traveled equation are linear.
Thus :
Train A's unit rate is 69 km per hour.
And
Train B's unit rate is 75 km per hour.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Train B is going faster because its unit rate is greater than Train A's unit rate .

What is the value of x?
Enter your answer in the box.
x = ____
Answer:
X=32
Step-by-step explanation:
since it is equilateral, all the angles are the same so they equal 60 , because those are the only possible angle measurements that an equilateral triangle can have.
we know that all the angles are equal to 60 so we set up an equation
2x-4=60
2x=64
x=64/2
x=32
How to do this problem? Please explain this in steps if possible. Thanks!
Answer: 10
Step-by-step explanation:
If two triangles are congruent, then they will have the exact same sides and angle measures.
AB=3x+1
BC=6
DE=2x
Solve for X by making 2x=6 because DE and BC are corresponding sides, indicating they are equal.
x=3, plug that in
AB=10

The number of road construction projects that take place at any one time in a certain city follows a Poisson distribution with a mean of 3. Find the probability that exactly four road construction projects are currently taking place in this city.
Answer:
The probability that exactly four road construction projects are currently taking place in this city is 0.168.
Step-by-step explanation:
Let X denote the number of road construction projects that take place at any one time in a certain city.
It is provided that X follows a Poisson distribution with parameter λ = 3.
Then the probability mass function of X is:
[tex]p_{X}(x)=\frac{e^{-\lambda}\cdot \lambda^{x}}{x!};x=0,1,2,3...[/tex]
Compute the probability that exactly four road construction projects are currently taking place in this city as follows:
[tex]P(X=4)=\frac{e^{-3}\cdot 3^{4}}{4!}[/tex]
[tex]=\frac{0.04979\times 81}{24}\\\\=0.16804125\\\\\approx 0.168[/tex]
Thus, the probability that exactly four road construction projects are currently taking place in this city is 0.168.
Using the Poisson distribution, it is found that there is a 0.1954 = 19.54% probability that exactly four road construction projects are currently taking place in this city.
We have only the mean for the discrete distribution, hence, the Poisson distribution is used.
Poisson distribution In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successes e = 2.71828 is the Euler number [tex]\mu[/tex] is the mean in the given interval.In this problem, the mean is of 3, hence [tex]\mu = 3[/tex].
The probability that exactly four road construction projects are currently taking place in this city is P(X = 4), hence:
[tex]P(X = 4) = \frac{e^{-3}3^{4}}{(4)!} = 0.1954[/tex]
0.1954 = 19.54% probability that exactly four road construction projects are currently taking place in this city.

What is the approximate area of the store in square feet?
O A 2.200
O B. 2,500
OC. 2,300
OD. 2,400
you’ve have by the end of today (12am)
Answer:
B. 2,500
Step-by-step explanation:
The diagram of the area of the store has been divided A and B as shown in the attachment below.
Dimensions of A:
(*Note: scale = 1 in to 16 ft)
Length = 4 inches
Actual length = 4*16 = 64 ft
Width = 1¾ inches
Actual width = 1¾*16 = 28 ft
Area of A = length * width = 64*28 = 1,792 ft²
Dimensions of B:
(*Note: scale = 1 in to 16 ft)
Length = 2¼ inches
Actual length = 2¼*16 = 36 ft
Width = 3 inches - 1¾ inches = 1¼ inches
Actual width = 1¼*16 = 20 ft
Area of A = length * width = 36*20 = 720 ft²
Area of the store = area of A and area of B = 1,792 + 720 = 2,512 ft²
Approximately, the are is 2,500 ft²

Jordan and Micheal are planing a graduation party with 45 guests. They want to seat an equal number of guests at each table.Each table should have more than one guest.List te different ways the guests and tables could arranged. Tell how many tales are needed for each group of guests. guests at each table.Each table should have more than one guest.List different ways the guests and tables
Answer:9 tables with 5 people at each one
Step-by-step explanation:
Using the factorization that defines the arrangement, there can be 9 tables for 45 guests with 5 guests per table. "A large number is factorised, which is the process of breaking it down into smaller numbers that, when multiplied together, produce the original number. A number is factorised when it is divided into its factors or divisors."
What is factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics. The Grouping method, the Difference in Two Squares, the Sum or Difference in Cubes, and the Greatest Common Factor (GCF) are the four main methods of factoring. Divide a number by the smallest prime number (larger than 1) that divides it evenly and leaves no remainder to find its factors quickly. As you receive more numbers, repeat this procedure until you reach 1.
Here,

when we factorize 45,
