Can you guess how many quarters TJ and Demi have in their pockets? And one Demi has nine more quarters than tj. And two if you double the number of quarters TJ has and triple the number of quarters then he has you would get 112 quarters in total. How many quarters does TJ have?​

Answers

Answer 1

Answer: TJ has 17 quarters and Demi has 26 quarters.

Step-by-step explanation:

Let t be the number of quarters TJ has and d be the number of quarters Demi has.

First, we will write an equation based on the first detail given:

       d = t + 9

Next, we will write an equation based on the second detail given:

       2t + 3d = 112

Now, we will substitute the first equation into the second and solve for t.

       2t + 3d = 112

       2t + 3(t + 9) = 112

       2t + 3t + 27 = 112

       5t + 27 = 112

       5t = 85

       t = 17 quarters

Lastly, we know that Demi has 9 more quarters than TJ. We will add 9.

       17 quarters + 9 quarters = 26 quarters

Answer 2

Answer:

TJ has 17 quarters.

Step-by-step explanation:

Let d and t equal the numbers of quarters Demi and TJ have, respectively.

"Demi has nine more quarters than TJ."

d = t + 9

"if you double the number of quarters TJ has and triple the number of quarters then he has you would get 112 quarters in total"

I think that "then he" above really should read "Demi."

2t + 3d = 112

d = t + 9

2t + 3d = 112

2t + 3(t + 9) = 112

2t + 3t + 27 = 112

5t = 85

t = 17

Answer: TJ has 17 quarters.

A construction company makes cement stairs from a wooden mold. The construction company must calculate the volume of the mold to determine how much cement they need to create the stairs. What is the volume of the wooden mold?

Answers

If the mold is not a rectangular prism, then the formula for its volume will be different, depending on its shape.

How to calculate the volume of the wooden mold?

To calculate the volume of the wooden mold, we need to know its dimensions. Let's assume that the mold is in the shape of a rectangular prism, with length (L), width (W), and height (H).

Then, the volume (V) of the wooden mold is given by the formula:

V = L x W x H

To find the values of L, W, and H, the construction company needs to measure the dimensions of the mold using a measuring tape or ruler. Once they have the measurements, they can plug them into the formula above to find the volume of the mold.

It's important to note that the units of measurement used for the dimensions of the mold should be consistent. For example, if the length and width are measured in feet, then the height should also be measured in feet, and the resulting volume will be in cubic feet.

If the mold is not a rectangular prism, then the formula for its volume will be different, depending on its shape.

An air conditioner is priced at $900. Amirah buys the air conditioner on hire purchase according to the following terms: downpayment of 20% and the remaining to be paid in monthly installments over 4 years at a simple interest rate of 10% per annum.



i) Find her monthly installment



ii) Find the total amount Amirah pays for the air conditioner.



iii) How much more does she have to pay for buying the air conditioner on hire purchase?

Answers

The monthly installment of the air conditioner is $ 21 and the total amount paid for the air conditioner is $ 1188. She has to pay $ 288 more for buying the air conditioner on hire purchase.

Original cost = $900

Downpayment = 20%

Downpayment = 20% of 90

= 0.20 * 900

=$180

For simple interest,

A = P + P * r * t

where A is the amount

P is the principal

r is the rate of interest

t is the time

Given,

P = Total cost - Downpayment

= 900 - 180

= $720

r = 10%

t = 4 years

A  = 720 + 720 * 0.10 * 4

= $ 1008

Number of months she has to pay = 4 * 12

= 48 months

Monthly installment = 1008 / 48

= $ 21

Total amount paid = Downpayment + Monthly installments

= 180 + 1008

= $ 1188

Money paid more = 1188 - 900

= $ 288

The main threat to concluding that the tutor was effective in helping students understand confounding and obscuring variables is the issue of 'practice effects'.

Practice effects occur when exposure to specific materials or questions during a study can artificially inflate performance on subsequent measures, such as an exam.

In this case, if the practice questions from the tutor were exactly the same as those on the exam.

Then the students who interacted with the tutor may have had an advantage on the exam .

Due to familiarity with the questions rather than a true understanding of the material.

The use of the same practice questions in the tutor and on the exam .

It represents a potential confounding variable that could affect the interpretation of the results.

It is possible that the tutor may have been effective.

But it is also possible that the practice effect of the repeated questions contributed to the observed improvement in performance.

Future research could use different practice questions in the tutor and on the exam.

You dog just had a litter of 9 puppies. Your mom is going to let you keep 2 of them. How many possible outcomes are there?



In a game, each player receives 7 cards from a deck of 52 different cards. How many different groupings of cards are possible in this game?



How many possible outcomes are there for a 4 digit ATM pin if the first number must be a 5?



How many three letter arrangements can be made from the letters in the word ocean?

Answers

Puppy outcomes: 36. Card groupings: 133,784,560. 5-digit PINs: 1,000. Three-letter arrangements: 24.

How many possible outcomes?

a) For the puppies, you have 9 choices for the first puppy and 8 choices for the second puppy. However, since the order in which you choose them does not matter (e.g., getting puppy A first and then puppy B is the same as getting puppy B first and then puppy A), we need to divide by the number of ways to arrange 2 items, which is 2! (2 factorial). Therefore, the number of possible outcomes is 9 * 8 / 2! = 36.

b) For the card game, each player receives 7 cards from a deck of 52 cards. The number of different groupings of cards can be calculated using combinations. The formula for combinations is nCr = n! / (r!(n-r)!), where n is the total number of cards (52) and r is the number of cards each player receives (7). Plugging in the values, we get 52C7 = 52! / (7!(52-7)!) = 133,784,560.

c) For the 4-digit ATM pin, the first number must be 5. The remaining three digits can be chosen from the numbers 0-9, excluding 5 (since it has already been chosen for the first digit). Therefore, there are 9 choices for the second digit, 10 choices for the third digit, and 10 choices for the fourth digit. Multiplying these choices together, we get 9 * 10 * 10 = 900 possible outcomes.

d) For the three-letter arrangements from the word "ocean," we have 5 letters to choose from. The first letter can be any of the 5 letters, the second letter can be any of the remaining 4 letters, and the third letter can be any of the remaining 3 letters. Multiplying these choices together, we get 5 * 4 * 3 = 60 possible arrangements.

If Mikal uses all his money to buy one type of flour, he has exactly enough money to buy either 12 pounds of wheat flour, or 6 pounds of rice flour, or 4 pounds of almond flour. If Mikal uses all his money to buy an equal number of pounds of all three types of flour, what is the total number of pounds of flour that he can buy?

Answers

The total number of pounds of flour he can buy is 7 pounds of flour

Let's assume that Mikal has $1 to spend on flour. According to the problem, he can buy:

- 12 pounds of wheat flour for $1, which means that the price of wheat flour is 1/12 = $0.0833 per pound.

- 6 pounds of rice flour for $1, which means that the price of rice flour is 1/6 = $0.1667 per pound.

- 4 pounds of almond flour for $1, which means that the price of almond flour is 1/4 = $0.25 per pound.

If Mikal spends $1 on an equal amount of all three types of flour, he will spend $1/3 = $0.3333 on each type of flour. To determine how many pounds of each type of flour he can buy, we need to divide $0.3333 by the respective price per pound of each type of flour:

- Wheat flour: $0.3333 / $0.0833 per pound = 3.9996 pounds (rounded to 4 pounds)

- Rice flour: $0.3333 / $0.1667 per pound = 1.9998 pounds (rounded to 2 pounds)

- Almond flour: $0.3333 / $0.25 per pound = 1.3332 pounds (rounded to 1 pound)

Therefore, Mikal can buy 4 pounds of wheat flour, 2 pounds of rice flour, and 1 pound of almond flour with $1. The total number of pounds of flour he can buy is:

4 + 2 + 1 = 7 pounds of flour.

At a used book sale, paperback books sell for $3 each and hardback books sell for $8 each. If Claude purchased 10 used books for a total cost of $45 at the used book sale, how many hardback books did he purchase?​

Answers

Claude purchased 3 hardback books

What is the meaning of purchase?

Purchase refers to the act of buying or acquiring a product, service, or other item in exchange for money or some other form of payment. Purchases can be made by individuals, businesses, or other organizations, and can be made in a variety of ways, including online, in-store, or through a third-party vendor.

Let's assume that Claude purchased x paperback books and y hardback books.

From the problem statement, we can set up a system of two equations to represent the information given,

x + y = 10 (the total number of books Claude purchased is 10)

3x + 8y = 45 (the total cost of the books Claude purchased is $45)

We can use the first equation to solve for x in terms of y:

x = 10 - y

Substituting this into the second equation,

3(10 - y) + 8y = 45

Simplifying the equation,

30 - 3y + 8y = 45

5y = 15

y = 3

Therefore, Claude purchased 3 hardback books. To find the number of paperback books, we can use the equation we derived earlier:

x = 10 - y = 10 - 3 = 7

So, Claude purchased 7 paperback books and 3 hardback books.

Answers

The absolute maximum value is 5 at x = 3/2 and the absolute minimum value is 4, which occurs at both x = 1 and x = 2.

To find the absolute maximum and minimum values of the function f(x) = -4x^2 + 12x - 4 on the interval [1, 2], we need to check the critical points and the endpoints of the interval.

First, let's find the critical points by taking the derivative of the function:

f'(x) = -8x + 12

To find the critical points, set f'(x) to 0 and solve for x:

-8x + 12 = 0
x = 3/2

Now, we have 3 points to check: x = 1, x = 3/2, and x = 2.

Evaluate the function at each point:

f(1) = -4(1)^2 + 12(1) - 4 = -4 + 12 - 4 = 4
f(3/2) = -4(3/2)^2 + 12(3/2) - 4 = -9 + 18 - 4 = 5
f(2) = -4(2)^2 + 12(2) - 4 = -16 + 24 - 4 = 4

Comparing the function values at these points, we find that the absolute maximum value is 5 at x = 3/2 and the absolute minimum value is 4, which occurs at both x = 1 and x = 2.

f(3/2) = -4(3/2)^2 + 12(3/2) - 4 = -9 + 18 - 4 = 5

f(2) = -4(2)^2 + 12(2) - 4 = -16 + 24 - 4 = 4

Comparing the function values at these points, we find that the absolute maximum value is 5 at x = 3/2 and the absolute minimum value is 4, which occurs at both x = 1 and x = 2.

The values are,

x =  15[tex]\sqrt{2}[/tex]([tex]\sqrt{2}[/tex] -1)/2

y = 15([tex]\sqrt{2}[/tex] -1)/2

z = 15

Labelling the given figure;

In ΔABC

Cos 60 = (y + z)/15[tex]\sqrt{2}[/tex]

⇒y + z = 15[tex]\sqrt{2}[/tex]/2   ....(i)               (since cos 60 = 1/2)

In ΔADC

sin 45 = z/15[tex]\sqrt{2}[/tex]

⇒ z = 15  ....(ii)                            (since sin45  = 1/[tex]\sqrt{2}[/tex])  

Now from (i) and (ii)

y = 15([tex]\sqrt{2}[/tex] -1)/2

In ΔABD

Sin 45 = y/x

⇒  1/[tex]\sqrt{2}[/tex] = (15([tex]\sqrt{2}[/tex] -1)/2)/x

⇒ x =  15[tex]\sqrt{2}[/tex]([tex]\sqrt{2}[/tex] -1)/2

Mrs. Logan's class is hiking. They increase their elevation by 100 ft every 2 min. What is the rate of their climbing?


A 10ftminftmin


B 50ftminftmin


C 100ftminftmin


D 200ftmin

Answers

The correct answer to this question is C, 100ft/min.

The rate of climbing can be calculated by dividing the increase in elevation (100 ft) by the time it takes to make that increase (2 min).

This gives a rate of 50ft/min. Therefore, the class is climbing at a rate of 100ft/min since the question asks for the rate of their climbing.

It's important to pay attention to the wording of the question to ensure that the correct answer is selected. In this case, the question specifically asks for the rate of climbing, not the rate of increase in elevation.

on stats-2, run an anova to see if there is a significant difference in whether or not customers purchase a bike depending on their career type. what can you conclude from the results assuming that the data is a valid representation of the total population of potential bike customers?

Answers

The first option is correct. There is no significant difference in the purchasing patterns across career types

How is a data valid  representation of the total population

In order for a dataset to be a valid representation of the total population, it needs to be collected in a way that ensures that it is a fair and accurate sample of the population.

One way to ensure this is through random sampling, where individuals are selected to participate in the study without any bias or preconceived notions about their characteristics. This helps to reduce the potential for selection bias and ensures that the sample is representative of the larger population.

Find the coordinates of the absolute extrema for f(x) on the closed interval [-4, 4]
x^3 - 3x^2 - 9x + 20

Answers

The coordinates of the absolute maximum point are (4, 24), and the coordinates of the absolute minimum point are (-4, -8).

To find the absolute extrema of the function[tex]f(x) = x^3 - 3x^2 - 9x + 20[/tex] on

the closed interval [-4, 4], we need to find the maximum and minimum

values of the function within the given interval.

Find the critical points of the function f(x) within the interval [-4, 4].

To find the critical points, we need to take the first derivative of the

function and set it equal to zero.

[tex]f(x) = x^3 - 3x^2 - 9x + 20[/tex]

[tex]f'(x) = 3x^2 - 6x - 9[/tex]

Setting f'(x) = 0, we get:

[tex]3x^2 - 6x - 9 = 0[/tex]

Dividing both sides by 3, we get:

[tex]x^2 - 2x - 3 = 0[/tex]

Factoring the quadratic equation, we get:

(x - 3)(x + 1) = 0

So, the critical points of the function within the interval [-4, 4] are x = -1 and x = 3.

Find the values of the function at the critical points and at the endpoints

of the interval [-4, 4].

To find the values of the function at the critical points and at the

endpoints of the interval, we evaluate the function at each of these

values.

f(-4) = -8

f(4) = 24

f(-1) = 24

f(3) = 2

Compare the values obtained in step 2 to find the maximum and minimum values of the function.

The maximum value of the function is 24, which occurs at x = -1 and x = 4.

The minimum value of the function is -8, which occurs at x = -4.

Why couldn’t Anybody see Ms Applebees apple?

Answers

Ms. Applebee's apple is because they lacked the necessary human capital to understand the play on words.

To begin with, let's define what we mean by capital. In economics, capital refers to any resource that can be used to produce goods or services. This can include physical capital, such as machinery and equipment, as well as financial capital, such as money and investments.

However, there is another type of capital that is just as important: human capital. Human capital refers to the skills, knowledge, and abilities that individuals possess, which can be used to create economic value. This can include things like education, training, and experience.

This is where the concept of human capital comes in. In order to "see" Ms. Applebee's apple (or capital), you need to have the skills and knowledge to understand the play on words. This requires a certain level of human capital - specifically, linguistic and cultural capital.

Linguistic capital refers to the ability to use language effectively, including understanding and interpreting language in different contexts. Cultural capital, on the other hand, refers to the knowledge and skills needed to navigate different cultural contexts and understand cultural references.

Use The Fundamental Theorem of Calculus, Part 2 to evaluate / - (13 – 12) dt.

Answers

The value of the integral [tex]\int -1^1 (13 - 12) dt[/tex] is 26.

How to evaluate the integral?

To evaluate the integral [tex]\int-1^1 (13 - 12) dt[/tex] , we need to find an antiderivative of the integrand, which is simply:

∫ (13 - 12) dt = 13t - 12

Using this antiderivative, we can evaluate the definite integral by applying the theorem:

[tex]\int-1^1 (13 - 12) dt = [13t - 12]_{(-1)^1[/tex]

Evaluating this expression at the limits of integration (-1 and 1), we get:

[13(1) - 12] - [13(-1) - 12]

Simplifying, we get:

= 13 - 12 + 13 + 12

= 26

Therefore, the value of the integral [tex]\int-1^1 (13 - 12) dt[/tex] is 26.

TJ’s drawer has many loose socks: 5 gray, 5 black, and 6 white. If two socks are randomly pulled out without replacement, what is the probability that he pulls 2 white socks?

Answers

The probability of TJ pulling 2 white socks is 0.125 or 12.5%.

What is the probability that TJ pulls 2 white socks?

There are 16 socks in total, so the probability of the first sock being white is 6/16.

Since we are not replacing the first sock, there are now 15 socks left, including 5 white socks.

So the probability of the second sock being white, given that the first sock was white, is 5/15.

To find the probability of both events occurring, we multiply the probabilities:

P(white and white) = P(white on first draw) × P(white on second draw, given that the first was white)

P(white and white) = (6/16) × (5/15)

P(white and white) = 1/8

So the probability of pulling 2 white socks is 1/8 or approximately 0.125.

Of(x) = 7x + 3


f(x) = 7(x+1) + 10


Of(x) = 3x + 7


f(x) = 3(x+1)+7

Answers

The explicit equation for the sequence 7, 10, 13, 16,... is an = 7 + 3n.

To find the explicit equation for the sequence 7, 10, 13, 16,..., we first need to identify the common difference.The common difference is the difference between any two consecutive terms in the sequence.

In this case, the common difference d is 10 - 7 = 3, 13 - 10 = 3, 16 - 13 = 3, and so on.

Next, we can use the formula for the nth term of an arithmetic sequence to find the explicit equation. The formula is:

an = a1 + (n - 1)d

where,

an = the nth term of the sequence

a1 = the first term of the sequence

d = the common difference

n = the number of the term we want to find

Since the sequence starts at x=0, we can rewrite the formula as: an = a0 + nd,

where a0 = 7 and d = 3.

Therefore, the explicit equation for the sequence is an = 7 + 3n

!!!HELPP ME ASAP!!!! Claude is reading a science fiction book in which aliens have dropped a fungus on a 10 square mile section of a planet. The fungus spreads rapidly, increasing the area it covers by 50% every hour. The total


area of the planet is 200 million square miles. Claude created an equation and determined that it will take approximately 41 hours for the fungus to cover planet What is the equation that Claude created?

Answers

The equation Claude created is: 10 * (1.5)^t = 200,000,000, where t represents the number of hours.

Let A be the initial area of the fungus that covers the 10 square mile section of the planet.

After 1 hour, the fungus increases in size by 50%, which means it multiplies by 1.5. Thus, the area covered by the fungus after 1 hour is:

A + 1.5A = 2.5AAfter 2 hours, the fungus increases again by 50%, so its area becomes:

2.5A + 1.5(2.5A) = 6.25A

In general, after n hours, the area of the fungus becomes: A(1.5)^n

Since we want the fungus to cover the entire planet, we need to solve the following equation: A(1.5)^41 = 200,000,000

Simplifying, we get:

A = 200,000,000 / (1.5)^41

Therefore, the equation that Claude created is:

A(1.5)^n = 200,000,000

where n is the number of hours it takes for the fungus to cover the planet.

Can someone help and explain the terms and sequence with answers please?

29, 22, 15, 8

B) these are the first five terms of another sequence.

4, 7, 12, 19, 28

Find the nth term.

Answers

A) The given sequence is decreasing by 7 each time. Therefore, the next term would be 1 less than 8, or 7.

B) The given sequence is increasing by successive odd integers, starting with 3. To find the nth term of this sequence, we can use the formula:

nth term = first term + (n-1) * common difference

The first term of this sequence is 4, and the common difference is the successive odd integers. The difference between each term and the previous term is 3, 5, 7, 9, and so on. So, the common difference is 2 more than the index of the term.

For example, the second term (n=2) is 7, which is 3 more than the first term. Therefore, the common difference is 3. The third term (n=3) is 12, which is 5 more than the second term. Therefore, the common difference is 5-3=2.

Thus, we can write the nth term as:

nth term = 4 + (n-1) * (n+1)/2

For example, the fourth term (n=4) would be:

nth term = 4 + (4-1) * 5/2 = 4 + 3*5/2 = 4 + 15/2 = 11.5

Therefore, the nth term of the sequence is 4 + (n-1) * (n+1)/2.
