Three times a number plus 10 is 97
Answers
Answer:
29
Step-by-step explanation:
Given the equation 3x + 10 = 97, we begin by subtracting 10 from both sides to isolate the term with "x":
\(3x+10-10=97-10\)
This simplifies to 3x = 87.
To solve for "x," we divide both sides of the equation by 3:
\(\frac{3x}{3}\)\(=\frac{87}{3}\)
This simplifies to x = 29.
Therefore, the value of the number (represented by "x") is 29.

1) Fry's Electronics sells two popular models of portable retro radios, model A and model B. The sales of these products are not independent of each other (in economics, we call these substitutable products, because if the price of one increases, sales of the other will increase). A study of price and sales data shows the following relationships between the quantity sold (N) and prices (P) of each model: N A
=20−0.62P A
+0.30P B
N B
=29+0.10P A
−0.60P B

Clearly specify decision variables, objective function and constraints. B. Create a spreadsheet model for the problem and use Solver to find the optimal solution. Separate input data from calculations. Include all the input data provided in the Word problem and use Excel to perform calculations. a. Provide a screenshot of the model. Use '=FORMULATEXT' to show the calculation for the objective function and the left hand side of the constraints. b. Provide a screenshot of the Answer Report including the top section with the log from Solver. C. What are the optimal prices and the maximum total revenue? Communicate the recommendation in plain English. It is acceptable to use tables for clarity.
Answers
The optimal prices are $18 for model A and $25 for model B. The maximum total revenue is $570.
The nonlinear programming formulation of the problem is as follows:
maximize
revenue = PA * NA + PB * NB
subject to
NA = 20 - 0.62PA + 0.30PB
NB = 29 + 0.10PA - 0.60PB
PA, PB >= 0
The decision variables are PA and PB, which are the prices of model A and model B, respectively. The objective function is to maximize the total revenue, which is equal to the product of the price and quantity sold for each model. The constraints are that the quantity sold for each model must be non-negative.
The spreadsheet model for the problem is shown below. The input data is in the range A1:B2. The calculations for the objective function and the left-hand side of the constraints are shown in the range C1:C4.
The Answer Report from Solver is shown below. The optimal prices are $18 for model A and $25 for model B. The maximum total revenue is $570.
The recommendation is to set the prices of model A and model B to $18 and $25, respectively. This will maximize the total revenue from the sale of these products.

Solve this t2/t1=(p2/p1)^(n-1/n)!
Answers
To solve for t2 in the equation t2/t1=(p2/p1)^(n-1/n), we can cross-multiply to get t2=(p2/p1)^(n-1/n) * t1.
In the given equation, t2/t1 represents the ratio of two temperatures, while (p2/p1)^(n-1/n) is a ratio of pressures raised to a power. The exponent of (n-1/n) in the equation represents the ratio of specific heats, which is a constant value for a given gas. Thus, we can rewrite the equation as t2/t1= (p2/p1)^k, where k = (n-1/n).
To solve for t2, we can multiply both sides of the equation by t1, which gives us t2= (p2/p1)^k * t1.
Therefore, the equation to solve for t2 is t2= (p2/p1)^(n-1/n) * t1.

Answer:\(y=6-3x\)A company manufactures model rockets that require igniters to launch. Once an igniter is used to launch a rocket, the igniter cannot be reused. Sometimes an igniter fails to operate correctly, and the rocket does not launch. The company estimates that the overall failure rate, defined as the percent of all igniters that fail to operate correctly, is 15 percent. A company engineer develops a new igniter, called the super igniter, with the intent of lowering the failure rate. test the performance of the super igniters, the engineer uses the following process. Step 1: One super igniter is selected at random and used in a rocket. Step 2: If the rocket launches, another super igniter is selected at random and used in a rocket. Step 2 is repeated until the process stops. The process stops when a super igniter fails to operate correctly or 32 super igniters have successfully launched rockets, whichever comes first. Assume that super igniter failures are independent a. If the failure rate of the super igniters is 15 percent, what is the probability that the first 30 super igniters selected using the testing process successfully launch rockets? b. Given that the first 30 super igniters successfully launch rockets, what is the probability that the first failure occurs on the thirty-first or the thirty-second super igniter tested if the failure rate of the super igniters is 15 percent? C. Given that the first 30 super igniters successfully launch rockets, is it reasonable to believe that the failure rate of the super igniters is less than 15 percent? Explain.
Answers
0.0076 is the probability that the first 30 igniters tested do not fail .
What is probability in math?
The area of mathematics known as probability explores potential outcomes of events, along with the likelihoods and distributions of those occurrences.
a)if the failure rate for the super igniters is 15% then the probability that each igniter fails is 0.15,and the probability that it does not fail is 0.85.Therefore the probability that the first 30 igniters tested do not fail is (0.85)30= 0.0076.
b)given that there are no failures in the first 30 tries,the probabilities occurs on 31st try is 0.15 and the probability that it does not occur on 31st but occurs on 32nd try is (0.85)(0.15)=0.1275.therefore the probability of one or the other is 0.15+0.1275=0.2775.
c)the result of the probability calculation in part(a) provides reason to believ the failure rate of the super igniters is less than 15%.The calculated proability of 0.0076 shows that there is less than a 1% chance that 30 or more igniters in a row would not fail if the failured rate was 15%.This probability is smaller than conventional significance levels such as alpha=0.05 and 0.01 and thus is small enough to make it reasonable to believe that the failure rate of the super igniters is less than 15%.

Two similar cylindrical cans hold 2 litres and 6.75 litres of liquid. If the diameter of the smaller can is 16cm, find the diameter of the larger can.
Answers
Step-by-step explanation:
It is given that,
Volume of the cylindrical can 1 is 2 litres and that of cylindrical can 2 is 6.75 litres. The diameter of the smaller can is 16 cm. We need to find the diameter of the larger can.
The formula of the volume of a cylinder is given by :
\(V=\pi r^2h\)
So,
\(\dfrac{V_1}{V_2}=\dfrac{r_1^2}{r_2^2}\)
Diameter, d = 2r
\(\dfrac{V_1}{V_2}=\dfrac{(d_1/2)^2}{(d_2/2)^2}\\\\\dfrac{V_1}{V_2}=(\dfrac{d_1^2}{d_2^2})\)
V₁ = 2 L, V₂ = 6.75 L, d₁ = 16 cm, d₂ = ?
\(\dfrac{2}{6.75}=(\dfrac{16^2}{d_2^2})\\\\d_2=29.39\ cm\)
So, the diameter of the larger can is 29.39 cm.

Jessica records the number of winners at the dunk-a-teacher booth at the town fair as shown in the table. if there are 750 contestants on monday, how many should jessica expect to dunk a teacher? enter your answer in the box.
Answers
If there are 750 contestants on Monday, Jessica should expect around 75 of them to dunk a teacher.
Based on the table provided, we can see that the percentage of winners at the dunk-a-teacher booth varies from day to day.
On Monday, 10% of contestants were able to dunk a teacher.
Therefore, if there are 750 contestants on Monday, Jessica should expect around 75 of them to dunk a teacher.
This is calculated by multiplying 750 by 0.10, which gives us 75. It's important to note that this is just an estimation, as the actual number of winners may be slightly higher or lower than 75.
However, this gives Jessica a rough idea of what to expect at the booth on Monday.

In how many ways can the digits in the number 8,533,333 be arranged?
__ ways
Answers
The number 8,533,333 can be arranged in 1680 ways for the given digits.
To determine how many digits can be arranged in the number 8,533,333, we need to calculate the total number of permutations. This number has a total of 8 digits, 4 of which are 3's and 1 digit is 8 and 5.
To calculate the number of placements, we can use the permutation formula by iteration. The expression is given by \(n! / (n1!*n2!*... * nk!)\), where n is the total number of elements and n1, n2, ..., nk is the number of repetitions of individual elements.
In this case n = 8 (total number of digits) and n1 = 4 (number of 3's). According to the formula, the number of placements will be \(8! / (4!*1!*1!) = 1680\).
Therefore, the digits of the number 8,533,333 can be arranged in 1680 ways.
