Carly bought 2 1/4 pounds of apples. she used 2/3 of the apples to make applesauce. how may pounds of apples did she have left

Answers

Answer 1

The pounds of apples that she has left is 3/4 pounds.

How many pounds of apples does she have left?

A mixed number is a number that is made up of a whole number and a proper fraction. An example of a mixed number is 1 1/4. Where 1 is the whole number and 1 /4 is the proper fraction.

The fraction of the apples used in making the applesauce = 2 1/4 x 2/3

9/4 = 3/2 = 1 1/2

Fraction of apples left = 2 1/4 - 1 1/2

[tex]2\frac{1}{4} - 1\frac{1}{2}[/tex]

[tex]1\frac{1 - 2}{4}[/tex] = [tex]\frac{3}{4}[/tex]

What I still need to know is, what's Jonothan FLAW

Answers

As portrayed in the show, his biggest flaw is not knowing how to be a man. He had spent his life avoiding her responsibility, but she came anyway. He unnecessarily bows to Daenerys after she agrees to fight the Night King.

Perhaps Jon's biggest lingering flaw can be seen in book five: he's not a very good communicator. He struggled to sell his long-term ideas to his subordinates, and he also struggled to balance being overly friendly with them and alienating them, and he chose the latter. Other characters portray him as gruff, hard to read, and lacking in articulation, which isn't great when you're trying to bring about sweeping social reform. This is especially serious when you are dealing with people who are ready to kill you to prevent the implementation of the aforementioned social reforms.

I always say that Robb and Jon have the opposite problem: Robb is very good at selling himself, selling his ideas and thinking short term.

Jon is better at long-term strategic thinking and big-picture thinking, but lacks Robb's ability to really bring people to him.

Then of course, perhaps paradoxically, you have the underlying temper that he sometimes explodes (think of him heaving Thorne's throat with one hand, strangling Iron Emmett, etc.). He also felt very self-pity and defensive about his half-blood identity, both before and after joining the Night's Watch, while considering himself socially and militarily superior to his brothers in the Night guard. He needs someone to line him up (Donal Nye in the book, Tyrion in the show).

Then you have his flaws, which others might interpret as strengths. Lots of people criticized Jon for getting too involved in politics, like helping Stannis, throwing Creeker Stark in an ice prison, and getting Aryskar Stark to marry Saigon. Effective and ruthless efficiency, in the eyes of some, could on the other hand be described as a senseless (insidious?) intervention, the Pink Letter is Jon's intervention, which catches up with him. I also don't think the fictional character Harry Potter is that exciting.

A population of 250 wild turkeys decreases by 2. 2% per year. At the end of 8 years, there will be approximately 209 turkeys in the population

Answers

Each year, the wild turkey population, which was once 250, drops by 2.2%. There will be around 209 turkeys left after 8 years.

Wild turkey populations are declining at a 2.2% annual pace. The initial population of 250 turkeys is anticipated to drop to around 209 turkeys after 8 years. Using the exponential decay formula, we can determine the rate of decline annually: P is the population at a certain moment, P0 is the starting population, r is the rate of reduction expressed as a decimal, and t is the time in years. P = P0 (1 - r)t. The answer to the r equation is r = (1 - (P/P0)(1/t)) = 0.022. As a result, the population is declining by 2.2% annually.

Using the bag of marbles below, find the probability of pulling a blue marble two times in a row. After pulling the first blue marble, you do NOT replace it in the bag before pulling the second one. Each marble has an equally likely chance of being pulled. Answer as a simplified fraction.​

Answers

The probability of picking two blue marbles is 1/21.

What is the probability?

Probability is used to determine how likely it is that a random event would occur. The probability of a random event happening lies between 0 and 1. If it is certain the event would happen, the probability value is 1 and if it is certain that the event would not happen, the probability value is 0.

Probability of picking two blue marbles = (number of blue marbles / total number of marbles) x (number of blue marbles -1 / total number of marbles - 1)

Total number of marbles = 7

A tractor dealer puts a markup of ​21% on cost on a part for which it paid ​$420. Find ​(a) the selling price as a percent of​ cost, ​(b) the selling​ price, and ​(c) the markup

Answers

the selling price as a percent of cost is 120.52%, b- the selling price is $508.20 and the markup is 20.95% of cost.

(a) To find the selling price as a percent of cost, we need to first find the selling price and then divide it by the cost and multiply by 100%.

The markup on cost is 21%, which means the dealer sells the part for:

420 + 0.21*420 = $508.20

So the selling price is $508.20 and the cost is $420.

The selling price as a percent of cost is:

508.20/420 * 100% = 120.52%

So the selling price is 120.52% of the cost.

(b) The selling price is $508.20.

(c) The markup is the difference between the selling price and the cost, expressed as a percentage of the cost:

Markup = (Selling price - Cost)/Cost * 100%

= (508.20 - 420)/420 * 100%

= 20.95%

So the markup is 20.95% of the cost.

If you place 37 foot ladder against the top of a 15 foot building

Answers

I you place the 37 foot ladder against the top of the 15 foot building, it will reach a height of 52 feet.

If you place a 37 foot ladder against the top of a 15 foot building, then the ladder will reach a height of 52 feet (37+15=52). To calculate this, you can use the formula for addition, which is x + y = z, where x is the height of the building, y is the height of the ladder, and z is the total height the ladder will reach. In this case, x = 15 and y = 37, so the total height the ladder will reach will be z = 15 + 37 = 52.

O RATIONAL EXPRESSIONS Multiplication and division of 3 rational expressions Simplify. (x^(2)+9x+14)/(2x)*(x^(2)-4x)/(x^(2)-49)-:(x-4)/(x-7)

Answers

The expression (x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) when simplified is 2x + 4

How to simplify the expression

Given that

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7)

To start with, we factorize the factors of the expression

The factored expressions are

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = (x + 2)(x + 7)/(2x) * x(x - 4)/(x - 7)(x + 7) ÷ (x-4)/(x-7)

Cancel out the common factors to reduce the expression

So, we have

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = (x + 2)/(2) * (x - 4)/(x - 7) ÷ (x-4)/(x-7)

Express division as product

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = (x + 2)/(2) * (x - 4)/(x - 7) * (x - 7)/(x - 4)

Evaluate the quotient

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = (x + 2)/(2)

So, we have

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = 2x + 4

Hence, the solution is 2x + 4

To find the area of the blue parallelogram, you can move the red triangle to the green triangle to make a rectangle. After doing this, what can you conclude about the formula for the area of a parallelogram?

Answers

The area of a parallelogram can be obtained from the formula for a rectangle by using the same base and height, leading to the formula Area of parallelogram = base x height.

By moving the red triangle to the green triangle, we create a rectangle with the same base and height as the original parallelogram. Therefore, the area of the original parallelogram is equal to the area of the rectangle, which is given by the formula:

Area of rectangle = base x height

We can conclude that the formula for the area of a parallelogram is also given by:

Area of parallelogram = base x height

This is because a parallelogram can be divided into two congruent triangles, and the area of each triangle is half the area of the parallelogram. Therefore, the area of a parallelogram is equal to the base times the height, which is the same as the formula for the area of a rectangle.

What is property of logarithms?

The properties of logarithms are a set of rules that can be used to manipulate logarithmic expressions, including the product, quotient, power, and change of base properties.

We are given that the employee's hourly wage after t years is given by the equation [tex]y=7.03(1.03)^t[/tex]. We need to find the amount of time t after which he will be earning $10.00 per hour. So we set y = $10.00 and solve for t as follows:

$10.00 = $[tex]7.03(1.03)^t[/tex]

Divide both sides by $7.03:

1.4246 = [tex]1.03^t[/tex]

Take the natural logarithm of both sides:

ln(1.4246) = ln([tex]1.03^t[/tex])

Using the property of logarithms that ln([tex]a^b[/tex]) = b * ln(a), we can simplify the right-hand side:

ln(1.4246) = t * ln(1.03)

The concept of simple interest is a type of interest calculation based on a fixed percentage rate applied to an initial amount of money, called the principal, for a specific period of time

To find the principal, we can use the formula:

Total Interest = (Principal x Rate x Time) / 100

Where,

Rate = Annual Rate of Interest

Time = Period in years

Plugging in the given values, we get:

1222 = (Principal x 6.5 x 4) / 100

(n-x)! is the binomial coefficient which counts the number of ways that x successes can be chosen from n trials.Using the formula, we have;P(X >= 8) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15)Here n = 15, p = 0.2 and q = 0.8P(X >= 8) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15)= 15C8 (0.2)^8 (0.8)^7 + 15C9 (0.2)^9 (0.8)^6 + 15C10 (0.2)^10 (0.8)^5 + 15C11 (0.2)^11 (0.8)^4 + 15C12 (0.2)^12 (0.8)^3 + 15C13 (0.2)^13 (0.8)^2 + 15C14 (0.2)^14 (0.8)^1 + 15C15 (0.2)^15 (0.8)^0= 0.0094 + 0.0267 + 0.0524 + 0.0864 + 0.1174 + 0.1312 + 0.1184 + 0.0352= 0.5771Therefore the probability that at least 8 fail the test is 0.5771 (rounded to four decimal places).Answer: 0.5771

The cubic function has three roots. Verify
that x=2 is one of them and find the other two.

Answers

a)  Verified

b)  4 + √7 and 4 - √7

Given a cubic function with three roots, one of the roots is given as x = 2. The other two roots can be found by using the factor theorem. Using factor theorem, we have(f(x) = x³ - 10x² + 27x - 18)(x - 2) is a factor of f(x)if and only if f(2) = 0.So, we have f(2) = 2³ - 10(2²) + 27(2) - 18 = 0. Therefore, (x - 2) is a factor of f(x) and we can find the other two roots by factorizing the cubic function. Using long division method, we get f(x) = (x - 2)(x² - 8x + 9) Now, to find the other two roots, we solve the quadratic equation x² - 8x + 9 = 0 using the quadratic formula. x = (-b ± √(b² - 4ac))/2a. We have a = 1, b = -8 and c = 9. Substituting the given values in the above formula, we get x = (8 ± √(8² - 4(1)(9)))/2= (8 ± √28)/2= 4 ± √7. Therefore, the three roots of the cubic function are 2, 4 + √7 and 4 - √7.

Carmen's swimming pool has the shape of a rectangular prism

with a length of 20 feet, a width of 10 feet, and a depth of 5

feet. The pool will be filled with water until the water level is 1 1/2 feet from the top of the pool. Which volume of water will be filled into the pool?


A. 1000 cubic feet

B. 700 cubic feet

C. 500 cubic feet

D. 300 cubic feet

Answers

[tex]1\dfrac{1}{2} = \dfrac{3}{2} = 1.5[/tex]

[tex]20 (10) (5-1.5) = 200(3.5) = 700 \ cubic \ feet[/tex]

Answer:

(B) 700 cubic feet

Step-by-step explanation:

The height of water in the pool is 5 - 1 1/2 = 3 1/2 feet.

The volume of water needed to fill the pool up to 3 1/2 feet is:

20 feet x 10 feet x 3 1/2 feet = 700 cubic feet

Therefore, the answer is (B) 700 cubic feet.

Answer:

7x = 7

with solution of x = 1

This is the first choice

Step-by-step explanation:

Choice 1
7x = 7 => x = 7/7 = 1

Choice 2
7x = 7x provides no additional info and therefore there are an infinite number of solutions; any value of  will satisfy

Choice 3
x + 1 = x + 1; infinite solutions for reasons cited under choice 2

Choice 4
x + 1 = x + 2
Eliminating x from both sides gives 1 = 2
Such an equation will have no solution; no value of x can satisfy the equation

Correct answer: Choice 1: 7x = 7

A dilation has center (0,0). Find the image of the point L(-4,3) for the scale
factor 3.

Answers

Answer: To find the image of point L(-4,3) after a dilation with a scale factor of 3 and center at the origin, we need to multiply the coordinates of point L by the scale factor.

The formula for dilation is:

(x', y') = (kx, ky)

where (x, y) are the original coordinates, (x', y') are the coordinates of the image, and k is the scale factor.

In this case, k = 3 and the coordinates of point L are (-4, 3).

So,

x' = kx = 3(-4) = -12

y' = ky = 3(3) = 9

Therefore, the image of point L(-4, 3) after the dilation with a scale factor of 3 and center at the origin is (-12, 9).
