Answer: x = 3/4
Step-by-step explanation:
4x + 9 = 12
- 9 - 9
4x = 3 Divide by 4 on both sides.
x = 3/4
Answer:
x = 3/4
Step-by-step explanation:
4x + 9 = 12
Step 1. subtract 9 from both sides
4x + 9 = 12
- 9 - 9
4x = 3
Step 2. divide by 4 to isolate x
4x = 3

Consider an espresso stand with a single barista. Customers arrive at the rate of 25 per hour according to a Poisson distribution. Service times are exponentially distributed with a mean service time of 1.5 minutes per customer. Answer: a. What is the service rate per hour for the expresso stand? b. What is the probability that the server is busy? c. What is the probability that the server is idle? d. What is the average number of customers waiting in line? e. What is the average time in minutes a customer spends waiting in line for service?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Arrival rate λ = 25 per hour
Service time = 1.5 minutes per customer
A.) The service rate per hour :
60 / service time = 60 / 1.5 = 40 customers per hour
B.) probability that server is busy
Utilization factor = arrival rate / service rate
= 25 / 40
= 0.625
C.) probability that server is idle :
1 - 0.625 = 0.375
D.) average Number of customers waiting on line ;
λ² / μ(μ - λ)
25² / 40(40 - 25)
625 / 40(15)
= 1.04
Average time spent waiting in line for service :
λ / μ(μ - λ) * 60
25 / 40 ( 40 - 25)
25 / 40(15)
0.0416666 * 60
= 2.5 minutes

Answer:
See image; y=1/2x + any negative number
Step-by-step explanation:
The slope is 1/2, meaning that it will go up one unit, and to the right two units (rise over run). The y-intercept needs to be negative, so it could be anywhere from 0<y< negative infinity. Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. M will be 1/2, and b can be any negative number. Included is an example, but it is not the only solution.

John and Nadim do the math homework together. When they find 9 - (-8), they get different answers. John claims the difference is 17. Nadim claims the difference is -1. Who is correct?
Answer:
John is correct
Step-by-step explanation:
The rule in mathematics states that
- × + = -
+ × + = +
- × - = +
Hence, for the homework,
9 - (- 8) = x
9 + 8 = 17
Therefore, John is correct and Nadim is incorrect.
At Finky Feed Store, Gerby purchased 7 pounds of cracked corn, 3 pounds of
sunflower seed, and 8 pounds of mixed bird seed for $31.00. Michael purchased
5 pounds of cracked corn, 4 pounds of sunflower seed, and 10 pounds of mixed
bird seed for $32.75. Jayleen purchased 4 pounds of sunflower seed and 12
pounds of mixed bird seed for $27.00.
If c represents cracked corn, s represents sunflower seeds, and b represents bird
seed, which of the systems of equations below can be used to determine the
price per pound of cracked corn, sunflower seed, and bird seed?
Answer:
[tex]7c + 3s + 8b = 31.00[/tex]
[tex]5c + 4s + 10b = 32.75[/tex]
[tex]4s + 12b = 27.00[/tex]
Step-by-step explanation:
Given
[tex]c = corn[/tex]
[tex]s = sunflower[/tex]
[tex]b= bird[/tex]
For Gerby:
Items: 7lb of c, 3lb of s and 8lb of b
Total: $31.00
This will be represented using sum of products as:
[tex]7c + 3s + 8b = 31.00[/tex]
For Michael:
Items: 5lb of c, 4lb of s and 10lb of b
Total: $32.75
This will be represented using sum of products as:
[tex]5c + 4s + 10b = 32.75[/tex]
For Jayleen:
Items: 4lb of s and 12lb of b
Total: $27.00
This will be represented using sum of products as:
[tex]4s + 12b = 27.00[/tex]
Hence: The systems of equation are:
[tex]7c + 3s + 8b = 31.00[/tex]
[tex]5c + 4s + 10b = 32.75[/tex]
[tex]4s + 12b = 27.00[/tex]

the graph shows a proportional relationship between the number of cans of tennis balls and the total number of tennis balls. What does the point (2, 6) represent in this situation? choose all that apply
Answer:
answer 1 and 4 a and d
Step-by-step explanation:
The required representation of (2, 6) is there are 6 balls in 2 cans.
Options A and D both are correct.
proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
The given relation of proportionality shown on the graph is given as,
y = 3x
where y is the number of tennis balls and x is the number of cans containing the tennis balls.
And (2, 6) represents the number of balls in two cans.
Thus, the required representation of (2, 6) is there are 6 balls in 2 cans.

Explanation:
The scale factor is found by dividing the image length over the preimage length. In this case, the scale factor is 28/8 = 7/2 = 3.5
This means the larger triangle's side is 3.5 times longer compared to the smaller triangle's corresponding sides.
This consequently means the perimeter of the larger figure being 3.5 times larger than the smaller perimeter.
----------
larger perimeter = (scale factor)*(smaller perimeter)
larger perimeter = (3.5)*(28)
larger perimeter = 98 inches

You purchased concentrated cleaner that must be diluted (watered down) before use. Container A is the cleaner, which is a 30% solution. Container B is pure water. You are mixing together the contents of Container A and Container B to produce 60 gallons of 8% solution. How many gallons from each container are needed to create the 60 gallons of 8% cleaning solution? Write your answers as integers only.
Container A: 30% Cleaning Solution =
gallons
Container B: Pure Water =
gallons
Answer:
Container A: 30% Cleaning Solution = 4.8 gallons
Container B: Pure Water = 55.2 gallons
Step-by-step explanation:
since 8% of 60 gallons is 4.8 that means their is 55.2 gallons of pure water
We need to mix two components (a cleaner that is 30% solution and pure water) such that we end with 60 gallons of 8% solution, and we want to know the volume of each of these two components that we need to use.
The solution is:
Container A: 30% Cleaning Solution = 16 gallons
Container B: Pure Water = 44 gallons
------------------------------------------
Now let's see how to solve this:
Let's start by defining variables:
x = volume of water used.y = volume of cleaner used.We know that we want to get 60 gallons, so we have that:
x + y = 60 gal.
And we want this to be an 8%, then we must have that the amount of solution on the left side is equal to the amount of solution on the right side.
on the left side the amount of solution is just 0.3*yon the right side the amount of solution must be (60 gal)*0.08(note that the percentages are used in decimal form).
Then we have:
0.3*y = (60 gal)*0.08
With this equation we can find the value of y:
y = (60 gal)*0.08/0.3 = 16 gal.
Now that we know the value of y, we can replace it in the equation:
x + y = 60 gal
to get the value of x:
x + 16gal = 60 gal
x = 60 gal - 16 gal = 44 gal.
So finally, we can conclude that you need to use 44 gallons of water and 16 gallons of cleaner.

Replace the Cartesian equation with an equivalent polar equation
x² + y² = 144
In polar coordinates, r ² = x ² + y ², so
x ² + y ² = 144 → r ² = 144
12² = 144, so this reduces to
r = 12
