26 less than twice a number is 4. Find each number

Answers

Answer 1

Answer:

15

Step-by-step explanation:

Let's call the number we try to find "[tex]x[/tex]"

In the problem, we know that "26 is less than twice a number" is the same as "4". So we can write this as an equation:

[tex]2x - 26 = 4[/tex]

Now we can solve for x by isolating it on one side of the equation.

First, we isolate "2x" by flipping "-26" to the other side, which will now be "26".

[tex]2x = 4 + 26[/tex]

Then we add

[tex]2x = 30[/tex]

finally, we isolate the x by dividing each side with 2

2x ÷ 2 = 30 ÷ 2
x = 15

How much money should Be deposited today in an account that earns 10.5 percent compounded monthly so that it will accumulate to $22,000 in four years

Answers

Answer:

$12,276.24

Step-by-step explanation:

22000 / (1 + 0.105/12)^4*12

12276.24

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

where A is the future value, P is the present value, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, we want to find the present value P that will accumulate to $22,000 in four years at an annual interest rate of 10.5% compounded monthly (i.e., n = 12). Therefore, we have:

A = $22,000
r = 0.105/12 (monthly interest rate)
n = 12
t = 4

Substituting these values into the formula and solving for P, we get:

P = A/(1 + r/n)^(nt) = $22,000/(1 + 0.105/12)^(12*4) ≈ $14,005.70

Therefore, the amount that should be deposited today in the account is approximately $14,005.70.

Given that the coefficient of x⁵ in the expansion of (1+kx)⁵ is -672 find the value of k

Answers

The value of k that satisfies the given condition is approximately 0.4041.

In the expansion of (1+kx)⁵, the coefficient of x⁵ is given by the term:

C(5,k) * (kx)⁵ = k⁵ * C(5,k) * x⁵

where C(5,k) is the binomial coefficient or the number of ways to choose 5 items out of k.

So, we have the equation:

k⁵ * C(5,k) = -672

We can use a table of binomial coefficients to find C(5,k) for different values of k, but this can be time-consuming. Alternatively, we can use the fact that C(5,k) = C(5,5-k) and rewrite the equation as:

k⁵ * C(5,5-k) = -672

Expanding C(5,5-k), we get:

k⁵ * C(5,5-k) = k⁵ * C(5,k) = -672

Now, we can use trial and error to solve for k. Using this method, we can find that k = -4 or k ≈ 0.4041. However, since k must be positive (since it appears as a factor in the expansion), the only valid solution is k ≈ 0.4041.

Answers

Answer:

We can write 4x^2 + y^2 - 4xy - 16 as the product:

(2x - y + 4)(2x - y - 4)

Step-by-step explanation:

To write 4x^2 + y^2 - 4xy - 16 as a product, we can use the technique of completing the square. First, we can rearrange the terms to group the x terms and the y terms:

4x^2 - 4xy + y^2 - 16

Next, we can complete the square for the x terms and the y terms separately. For the x terms, we can add and subtract (2x)^2:

4x^2 - 4xy + (2x)^2 - (2x)^2 + y^2 - 16

Simplifying the first three terms gives:

(2x - y)^2 - (2x)^2 + y^2 - 16

For the y terms, we can add and subtract 16:

(2x - y)^2 - (2x)^2 + (y - 4)^2 - 16^2

Simplifying the second term gives:

-(4x^2) + 16x - (y^2) + 16y - 16^2

Therefore, we can write 4x^2 + y^2 - 4xy - 16 as the product:

(2x - y + 4)(2x - y - 4)

Answers

The caloric content for ice cream C is 250 calories while the caloric content for ice cream B is 270 calories.

How to determine the caloric content

To determine the caloric content, we will assign algebraic notations to each of the dessert types.

1 Icecream + 2 Blueberry pie =   790 calories

3 icecream + 2 Blueberry pie = 1290 calories

Now the first equation will be subtracted from the second equation as follows:

2 icecream = 500 calories

So, 1 ice cream is 250 calories.

Also, since, 1 icecream serving equals 250 calories, 2 Blueberry pies = 790 - 250 = 540 calories, and 1 Blueberry pie equals 270 calories.

We can start by isolating the variable b on one side of the inequality. We can do this by subtracting 5 from both sides of the inequality:

-3 - 5 > -b

Simplifying the left-hand side of the inequality, we get:

-8 > -b

To isolate b, we can multiply both sides of the inequality by -1. When we do this, we need to reverse the inequality sign:

8 < b

So the solution to the inequality is:

b > 8

This means that b must be greater than 8 for the inequality to be true.

b) if you rolled a pair of fair dice 180 times, how many times would you expect to roll a total of five?​

Answers

Answer:

Expected number of times to roll a total of 5 = Probability of rolling a total of 5 x Total number of rolls

                                                      = (1/9) x 180

                                                      = 20

Step-by-step explanation:

The diagram is not visible in the question. However, I can provide a general method to solve the problem.

a) To find the probability of rolling a total of 5, we need to count the number of ways we can get a sum of 5 and divide it by the total number of possible outcomes. From the diagram, we can see that there are four ways to get a sum of 5: (1,4), (2,3), (3,2), and (4,1). Since each die has six equally likely outcomes, there are 6 x 6 = 36 possible outcomes in total. Therefore, the probability of rolling a total of 5 is:

Probability of rolling a total of 5 = Number of ways to get a total of 5 / Total number of possible outcomes

                                   = 4/36

                                   = 1/9 (in its simplest form)

b) If we rolled a pair of fair dice 180 times, the expected number of times we would roll a total of 5 can be calculated as follows:

Expected number of times to roll a total of 5 = Probability of rolling a total of 5 x Total number of rolls

                                                      = (1/9) x 180

Answers

To calculate the total number of ways the customer can select 4 appetizers, 9 main courses, and 3 desserts, we can use the formula for combinations:

Total number of ways = (Number of ways to select appetizers) x (Number of ways to select main courses) x (Number of ways to select desserts)

Number of ways to select appetizers = C(5,4) = 5

Number of ways to select main courses = C(11,9) = 330

Number of ways to select desserts = C(4,3) = 4

Therefore, the total number of ways the customer can select 4 appetizers, 9 main courses, and 3 desserts is:

Total number of ways = 5 x 330 x 4 = 6,600

So, there are 6,600 ways the customer can select the items for the banquet.

The half-life of the particular compound is approximately 9.4 days. (Correct choice: B)

How to find the half-life of a compound

The statement indicates the decay function of a particular compound, which is an exponential function of the form:

y = a · exp(- λ · t)

Where:

a - Initial mass of the compound.λ - Decay constant, in days⁻¹.t - Time, in days.

The half-life of the particular compound is determined by the following expression:

t = ㏑ 2 / λ

Where t is the half-life.

If we know that λ = 0.0736, then the half-life of the particular compound is:

t = ㏑ 2 / 0.0736

t = 9.4 days

Making an Informed Decision Using the Quantitative Reasoning Process
Step 1: Understand the Problem
Keep the Old Car or Buy a Used Car
Manny is an online student who currently owns an older car that is fully paid for. He drives, on average, 190 miles per week to commute to work. With gas prices currently at $
2.9 per gallon, he is considering buying a more fuel-efficient car, and wants to know if it would be a good financial decision.
The old car Manny owns currently gets 18 miles per gallon for average fuel efficiency. It has been a great vehicle, but with its age, it needs repairs and maintenance that average $
770 per year (as long as nothing serious goes wrong).
The newer, more fuel-efficient car that he is looking at to purchase will cost a total of $
6,500 over a three-year loan process. This car gets 32 miles per gallon and would only require an average of $
10 per month for general maintenance. To help make a decision, Manny wants to calculate the total cost for each scenario over three years. He decides to use the quantitative reasoning process to do this.
Step 2: Identify variables and assumptions
Manny has identified some key variables for his situation. Select the two variables that should be removed from his list because they do not apply to the current situation.
Manny’s graduation date from elementary school.
The cost of repairs on the old car.
The cost of gas.
The number of miles Manny drives each week.
Manny’s wages.
The loan cost of the used car.
The year Manny was born.
The cost of the used car.
Manny has also made a list of key assumptions he will be using to make his decision. Check the boxes for the three assumptions from his list that are not useful in this scenario.
Manny assumes that nothing will go seriously wrong with either car during this three year period.
Manny assumes the loan period will be 3 years.
Manny assumes gas costs will remain about the same over the three years.
Manny assumes he will continue to go running in the mornings every weekday for the next three years.
Manny assumes there are 52 weeks in a year.
Manny assumes his lunches will continue to cost about the same for the next three years.
Manny assumes he will continue to drive about the same number of miles each week over this three year period.
Manny assumes he will still like spinach at the end of three years no matter which choice he makes.
Step 3: Apply Quantitative Tools
Use computational and algebraic tools to quantify the total costs (gas, maintenance/repairs, purchase price) for each scenario over the three years.
Round your answers to the nearest dollar.

Please dont copy the answer from online and post it here its wrong.In the main: Declare and create two arrays called nums1 and nums2 to eventually store 15 integers each.Declare a third array called nums3 and assign to it 15 values of your choice (from 1 to 30 BUT NOT in sorted order), for example {25,12,6,2,30}Write a method called initArray to initialize an array of int to values from 0 to 14 using a loop. ( write a method that called initArray to assign an array integers 0 to 14 using a loop.Write a method called displayArray to display all numbers in an array of int on one line using this format: 0 1 2 3 4 and so on. Back in the main: Write the code that calls the initArray method passing in nums1 Write the code that calls the displayArray method first passing in nums1, then passing in nums3. Display an appropriate message before calling the display array so that your results look like this: The nums1 array after initializing: 0 1 2 3 4 and so on The nums3 array after initializing: 25 12 6 2 30 and so on5. Write a method called genRandom which takes the array nums2 as a parameter and fills it with random numbers between 1 and 100.in a for loop, Back in the main:Add a call to the genRandom methods passing in nums2 after providing an appropriate message explaining what the output will be. Your output should looks like this: The nums2 array after initializing: 17 4 12 (random numbers different each time) and so onWrite a method called sumRandom which will take an array as a parameter. It sums all numbers in the array and returns the sum as the value of the method.Back in the main: Add a call to the sumRandom method passing it nums2, then display a message telling what the output is followed by the results. (REMEMBER: when a method returns a value, you need to supply a variable to receive the answer in the calling statement.Write a method called underForty which takes an array as a parameter.
