The expression -25t+1250 represents the volume of liquid of a container after t seconds. The expression 50t+250 represents the volume of liquid of another container after t seconds. What does the equation -25t+1250=50t+250 mean in this situation?
Answer:
t = 13.33 second
Step-by-step explanation:
Given:
Equation first -25t+1250
Equation second 50t+250
Computation:
-25t+1250=50t+250
75 t = 1,000
t = 13.33 second
Means in t (13.33) second both container have same amount of liquid

Bob is going on a bike ride. He rides for 7 hours for a total of 105 miles. How fast did he ride?Immersive Reader
(1 Point)
15 miles per hour
735 miles per hour
0.066 miles per hour
Answer:
15 miles per hour.
Step-by-step explanation:
105/7=15
Given the problem below what mistake did Bob make in solving the equation? Bob and his friends paid $30 for 3 sandwiches and and 3 bottles of water.
-Each sandwich cost the same amount.
-The bottles of water cost $1.50 each.
The equation 3(x + 1.50) = 30 can be used to determine x, the cost of each sandwich. Bob solved the equation using these steps: 3(x + 1.50) =30
3x + 1.50 = 30
3x = 28.50
x = 9.50
Answer:
Bob forgot to distribute 3 to 1.50 in the parentheses
Step-by-step explanation:
Bob made the mistake in his first step.
In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.
But, Bob only distributed it to x, which led him to get the wrong answer.
So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50

Step-by-step explanation:
A court holds jurisdiction over five counties, and the juries are required to be made up in a representative manner from the eligible populations of these five counties. An investigator notices that the county where she lives has 14% of the total population of the five counties eligible for jury duty, yet records reveal that over the past five years only 122 out of the 1386 jurors used by the court reside in her county. Do you feel that this constitutes reasonable evidence that the jurors are not being randomly selected from the total population
Answer:
Yes.
I feel that since only about 9% of the jurors are being appointed from the county, instead of the more representative 14%, this constitutes reasonable evidence that the jurors are not being randomly selected from the total population.
Step-by-step explanation:
a) Data and Calculations:
County population proportion = 14%
This implies that the country is supposed to have at least 1,386 * 14% = 194 of the jurors used by the court.
Evidence from records show that the county has only 122 of 1,386 = 9% (122/1,386)
This means that about 72 (194 - 122) jurors are not being appointed from the county.
And 72 represents about 5% of 1,386 (72/1,386). This number is more than half of those being appointed from the county or more than 50% or precisely 59%.
Therefore, this constitutes reasonable evidence that the jurors are not being randomly selected from the total population. The selection is not representative of the population characteristics.

A rental car company charges $68.80 per day to rent a car and $0.08
for every mile driven. Paisley wants to rent a car, knowing that:
• She plans to drive 325 miles.
• She has at most $370 to spend.
Write and solve an inequality which can be used to determine d, the
number of days Paisley can afford to rent while staying within her
budget.
Answer:
5 days maximumStep-by-step explanation:
Given
Daily charge = $68.80Charge per mile = $0.08Target distance = 325 milesMoney limit = $370Required inequality:
68.8d + 325*0.08 ≤ 370Solving for d:
68.8d + 26 ≤ 37068.8d ≤ 344d ≤ 344/68.8d ≤ 5Up to 5 days is the answer

Automobiles arrive at the drive-through window at a post office at the rate of 7 every 10 minutes. The average service time is 7 minutes. The Poisson distribution is appropriate for the arrival rate and service times are exponentially distributed. (Note: the given equations are NOT necessarily in the correct order.) What is the average time a car is in the system?Formulas for 13.17 What is the average number of cars in the system? What is the average time cars spend waiting to receive service? What is the average number of cars in line behind the customer receiving service? What is the probability that there are no cars at the window? What percentage of the time is the postal clerk busy? What is the probability that there are exactly two cars in the system?
Answer:
1) the average time a car is in the system is 0.1587 min
2) the average number of cars in the system 0.1111
3) the average time cars spend waiting to receive service is 0.01587 min
4) the average number of cars in line behind the customer receiving service is 0.01111
5) the probability that there are no cars at the window is 0.9
6) the percentage of time that the postal clerk is busy is 10%
7) the probability that there are exactly two cars in the system is 0.1217
Step-by-step explanation:
Given that;
Arrival rate λ = the rate of 7 every 10 minutes = 7/10 = 0.7
Average service time μ = 7 minutes
The Poisson distribution is appropriate for the arrival rate and service times are exponentially distributed.
1) What is the average time a car is in the system?
Average in the system W = 1 / (μ - λ)
= 1 / (7 - 0.7) = 1 / 6.3 = 0.1587 min
therefore the average time a car is in the system is 0.1587 min
2) What is the average number of cars in the system?
Average number of cars L = λ / (μ - λ)
= 0.7 / (7 - 0.7) = 0.7/6.3 = 0.1111
Therefore the average number of cars in the system 0.1111
3) What is the average time cars spend waiting to receive service?
Average time spend waiting for services Wq = λ / μ(μ - λ)
= 0.7 / 7(7 - 0.7) = 0.7/44.1 = 0.01587 min
Therefore the average time cars spend waiting to receive service is 0.01587 min
4) What is the average number of cars in line behind the customer receiving service?
average number of cars in line behind the customer receiving service
Lq = λ² / μ(μ - λ) = (0.7)² / 7(7 - 0.7) = 0.49 / 44.1 = 0.01111
Therefore the average number of cars in line behind the customer receiving service is 0.01111
5) What is the probability that there are no cars at the window?
probability that there are no cars at the window = 1 - (λ / μ)
= 1 - (0.7 / 7) = 1 - 0.1 = 0.9
Therefore the probability that there are no cars at the window is 0.9
6) What percentage of the time is the postal clerk busy?
percentage of the time is the postal clerk busy = (λ / μ)
= (0.7 / 7) = 0.1 ≈ 10%
Therefore the percentage of time that the postal clerk is busy is 10%
7) What is the probability that there are exactly two cars in the system?
the probability that there are exactly two cars in the system = (λ²e^-λ) / 2!
= (0.7²e^-0.7) / 2! = 0.2433 / 2 = 0.1217
Therefore the probability that there are exactly two cars in the system is 0.1217

IF AABD
ACBE, find the value of x.
27 cm
12 cm
SE
E
23.4 cm
Answer:
[tex] x = 10.4 [/tex]
Step-by-step explanation:
Since ∆ABD is similar to ∆CBE, therefore, the ratio of their corresponding side lengths would be equal to each other. Thus:
[tex] \frac{BD}{BE} = \frac{AD}{CE} [/tex]
BD = 12 cm
BE = x
AD = 27 cm
CE = 23.4 cm
Plug in the values
[tex] \frac{12}{x} = \frac{27}{23.4} [/tex]
Cross multiply
[tex] x \times 27 = 23.4 \times 12 [/tex]
[tex] 27x = 280.8 [/tex]
Divide both sides by 27
[tex] x = 10.4 [/tex]

The red lines mean the sides with the lines are the same. The red arc means those angles are the same.
Using that information you know the angle where the two same sides connect would also be the same.
So you have one side (S) and 2 angles (A) that are identical.
You can use B. ASA
