kayla has 7 8 pound of white flour and 4 8 pound of wheat flour. she uses 3 8 pound of the white flour and 1 8 pound of the wheat flour in a recipe she is making. how much flour does kayla have left? enter your answer in the boxes. express the answer in simplest form.
Answers
As per the given fraction, Kayla has 7/8 pound of flour left in total.
Let's start by looking at the amount of white flour Kayla has. She has 7/8 pounds of white flour, and she uses 3/8 pounds in the recipe. To figure out how much white flour she has left, we need to subtract the amount she used from the amount she had to start with:
7/8 - 3/8 = 4/8
So Kayla has 4/8 pounds of white flour left. But we can simplify this fraction by dividing both the numerator and the denominator by 4:
4/8 ÷ 4/4 = 1/2
So Kayla has 1/2 pound of white flour left.
Now let's look at the wheat flour. Kayla has 4/8 pounds of wheat flour, and she uses 1/8 pound in the recipe. To figure out how much wheat flour she has left, we need to subtract the amount she used from the amount she had to start with:
4/8 - 1/8 = 3/8
So Kayla has 3/8 pound of wheat flour left.
To find out how much flour Kayla has left in total, we need to add the amount of white flour she has left to the amount of wheat flour she has left:
1/2 + 3/8 = 4/8 + 3/8 = 7/8

Use Newton's Method to find the two solutions of e^2= 6x to six significant figures.
For this problem you will need to use the fact that the exponential equals its own derivative, i.e.,
(d/dx) e^x = e^x
Xleft =_____
Fright=_____
Answers
The two solutions to e² = 6x using Newton's method are x_left = 1.23151 and x_right = 2.157545.
What is the solution of the function?To find the solutions of e² = 6x using Newton's Method, we will follow these steps:
Let f(x) = e² - 6x. Then we want to find the roots of f(x) = 0, which are the solutions to e² = 6x.
We need to choose a starting point x₀. A good choice is x₀ = 1, since it's a reasonable approximation to the solutions.
Apply Newton's Method to find the next approximation x₁:
x₁ = x₀ - f(x₀)/f'(x₀),
where;
f'(x) = -6 is the derivative of f(x).Plugging in the values, we get:
x₁ = x₀ - (e² - 6x₀)/(-6) = x₀ + (e²/6 - x₀)
Use x₁ as the new starting point and repeat the process until we achieve the desired level of accuracy.
In this case, we want to find the solutions to six significant figures, so we will repeat the process until the difference between xₙ and xₙ₋₁ is less than 0.000005 (the sixth decimal place).
Using a calculator, we can apply Newton's Method iteratively to find the two solutions:
Iteration 1:
x₁ = x₀ - f(x₀) / f'(x₀)
x₁ = 1 - (e² - 6)/(-6) = 1.231509
Iteration 2:
x₂ = 1.231509 - (e² - 6)/(-6) = 1.463018
Iteration 3:
x₃ = 1.463018 - (e² - 6)/(-6) = 1.694527
Iteration 4:
x₄ = 1.694527 - (e² - 6)/(-6) = 1.926036
Iteration 5:
x₅ = 1.926036 - (e² - 6)/(-6) = 2.157545
The second solution to six significant figures is x_right = 2.157545

How much more expensive is it, per pound, to buy chicken thighs at Store B than at Store A?
Answers
Answer:
To find out how much more expensive it is, per pound, to buy chicken thighs at Store B than at Store A, we need to compare the cost per pound at each store.
At SuperGrocery B, we know that 3 pounds of chicken thighs cost $34.80, so the cost per pound is:
$34.80 / 3 pounds = $11.60 per pound
At SuperGrocery A, we can use the information in the table to find the cost per pound for each amount of chicken thighs:
For 1.5 pounds of chicken thighs:
$13.52 / 1.5 pounds = $9.01 per pound
For 3 pounds of chicken thighs:
$27.03 / 3 pounds = $9.01 per pound
For 3.5 pounds of chicken thighs:
$31.54 / 3.5 pounds = $9.01 per pound
For 4.5 pounds of chicken thighs:
$40.55 / 4.5 pounds = $9.01 per pound
So the cost per pound of chicken thighs at SuperGrocery A is $9.01 per pound, which is less expensive than the cost per pound at SuperGrocery B, which is $11.60 per pound.
To find the difference between the two prices, we can subtract the cost per pound at SuperGrocery A from the cost per pound at SuperGrocery B:
$11.60 per pound - $9.01 per pound = $2.59 per pound
Therefore, it is $2.59 more expensive, per pound, to buy chicken thighs at SuperGrocery B than at SuperGrocery A.
one business has a large amount of debt on which it pays an annual yield of 8%. a competitor has no debt, and any excess money goes into the bank and earns a yield of 2.3%. each of these businesses bids on a contract which pays $ 40,000 in one year and nine months. indicate which company gives this contract a higher present value, and calculate the difference between these present values, rounding to the nearest dollar. [hint: for both businesses the yield is treated as positive.]
Answers
This gives us a present value for the company with debt of $35,564 and a present value for the competitor without debt of $36,944. The difference in present values is $1,380, rounded to the nearest dollar. Therefore, the company with debt gives the contract a higher present value of $1,380.
The company with debt will have the higher present value for this contract. This is because, despite having a higher yield, the competitor without debt is only earning 2.3% on their excess money, while the company with debt is earning 8%.
To calculate the difference in present values, we need to first calculate the present value of each company's contract. To do this, we will use the present value formula, which is:
[tex]PV = C / (1 + r)n[/tex]
Where C is the contract amount, r is the rate of return, and n is the number of years. For the company with debt, we can substitute $40,000 for C, 8% for r, and 1.75 for n. For the competitor without debt, we can substitute $40,000 for C, 2.3% for r, and 1.75 for n.

The assessed value of the Weber family’s house is $186,000. The annual property tax is 2. 15% of assessed value. What is the property tax on the Webers home?
Answers
the property tax on the Weber family's home is $3,999. To find the property tax on the Weber family's home, we can use the formula:
Property tax = assessed value x tax rate
First, we need to convert the tax rate from a percentage to a decimal. We can do this by dividing the tax rate by 100:
2.15% ÷ 100 = 0.0215
Now we can plug in the values we know into the formula:
Property tax = $186,000 x 0.0215
Property tax = $3,999
So the property tax on the Weber family's home is $3,999.
Property taxes are a common way for local governments to generate revenue to fund public services like schools, roads, and emergency services. The tax rate is usually based on the assessed value of the property, which is determined by a local assessor's office. It's important for homeowners to be aware of the property tax rates in their area so they can budget for this expense. Some homeowners may be eligible for property tax exemptions or reductions, so it's also worth checking with the local assessor's office to see if there are any options available.

WHAT IS TRIGONOMETRY ?
Trigonometry is a branch of mathematics that deals with the study of the relationships between the sides and angles of triangles. It is used to solve problems involving distances, heights, angles, and other geometric measurements. Trigonometric functions such as sine, cosine, and tangent are used to relate the angles of a triangle to its sides. Trigonometry has many practical applications in fields such as engineering, physics, and architecture, and is essential for understanding and solving problems involving waves, oscillations, and periodic phenomena. It is also used in navigation, surveying, and astronomy, among other areas.
To solve this problem, we need to use the concept of right triangle trigonometry.
Let's assume that point C is directly opposite the midpoint of AB, and that the distance from point C to the midpoint of AB is x. Then we can draw a right triangle with legs of length x and 25 (half of 50) and a hypotenuse of length d (the distance from point C to each landing point).
Using the Pythagorean theorem, we can write:
d^2 = x^2 + 25^2
We also know that the angles opposite the legs of the right triangle are complementary, so we can use the tangent function to write:
tan(theta) = x/25
where theta is the angle between the hypotenuse and the side of length 25.
We can rearrange this equation to solve for x:
x = 25 tan(theta)
Now we can substitute this expression for x into the equation for d^2:
d^2 = (25 tan(theta))^2 + 25^2
Simplifying this equation, we get:
d^2 = 25^2 (tan^2(theta) + 1)
Finally, we can use the fact that tan(theta) is equal to the height of the opposite bank divided by the distance from point C to the midpoint of AB. Let's call this distance y. Then we have:
tan(theta) = y/x
Substituting this expression for tan(theta) into the equation for d^2, we get:
d^2 = 25^2 (y^2/x^2 + 1)
So the distance from each landing point to the boat pulled ashore at point C is given by:
d = sqrt(25^2 (y^2/x^2 + 1))
where x and y are the distances from point C to the midpoint of AB and the opposite bank, respectively.

tycho plans his running training. each week he wants to go for a run on the same weekdays. he never wants to go for a run on two consecutive days. but he wants to go for a run two days a week. how many different weekly plans meet those conditions?
Answers
There are 4 different weekly plans that meet the condition
If Tycho wants to go for a run on the same weekdays every week, there are 7 choices for the first day of the week, 6 choices for the second day of the week, and 5 choices for the third day of the week (since he can't run on two consecutive days).
However, we have to be careful not to overcount the number of plans that meet the conditions. For example, if Tycho chooses Monday and Tuesday as his running days, that's the same as choosing Tuesday and Monday.
To avoid overcounting, let's first count the total number of possible plans, regardless of whether they meet the conditions or not. We can choose any two days of the week for Tycho to run, which can be done in 7 choose 2 ways (or C(7,2) ways), since order doesn't matter.
C(7,2) = 7!/(2!(7-2)!) = 21
So there are 21 possible plans, regardless of whether they meet the conditions or not.
Now let's count the number of plans that meet the conditions. Since Tycho wants to run on two days a week and not on consecutive days, there are only two possible patterns: (1) run on Monday and Thursday, or (2) run on Tuesday and Friday.
Each pattern can be done in 2 ways: either run on Monday and Thursday, or run on Thursday and Monday. Similarly, either run on Tuesday and Friday, or run on Friday and Tuesday.
So there are 4 plans that meet the conditions: (Monday, Thursday), (Thursday, Monday), (Tuesday, Friday), and (Friday, Tuesday).

a centrifuge in a medical laboratory rotates at an angular speed of 3450 rev/min in the positive direction. when switched off, it rotates through 45.8 revolutions before coming to rest. Find the constant angular acceleration of the centrifuge.
Answers
The constant angular acceleration of the centrifuge is approximately [tex]-331283[/tex] rad/min² in the negative direction.
To find the constant angular acceleration of the centrifuge, we can use the following kinematic equation:
ω² = ω₀² + 2αθ
Here, ω is the final angular velocity (0 rad/min, since it comes to rest), ω₀ is the initial angular velocity (3450 rev/min), α is the constant angular acceleration we want to find, and θ is the angular displacement (45.8 revolutions).
First, we need to convert the given angular values to radians. We know that 1 revolution equals 2π radians.
Initial angular velocity, ω₀ = 3450 rev/min × 2π rad/rev = 6900π rad/min
Angular displacement, θ = 45.8 rev × 2π rad/rev = 91.6π rad
Now, substitute the values into the kinematic equation:
[tex]0 = (6900π)² + 2α(91.6π)[/tex]
[tex]α = - (6900π)² / (2 × 91.6π)[/tex]

(x - 3)(x + 4) What is the horizontal distance between the two x-intercepts?
Answers
Answer:
The horizontal distance between the two x-intercepts is 7 units.
Step-by-step explanation:
What are the x-intercepts?The x-intercepts are the points at which the graph of a function or equation crosses the x-axis. At these points, the value of y is zero.
Therefore, to find the x-intercepts of the given expression, set the expression equal to zero and solve for x:
(x - 3)(x + 4) = 0
This equation is true if and only if either x - 3 = 0 or x + 4 = 0, which means the x-intercepts are at x = 3 and x = -4.
The horizontal distance between these two points is the absolute value of the difference between the x-coordinates of the x-intercepts:
|3 - (-4)| = |3 + 4| = 7
Therefore, the horizontal distance between the two x-intercepts is 7 units.
one of four different prizes was randomly put into each box of a cereal. if a family decided to buy this cereal until it obtained at least one of each of the four different prizes, what is the expected number of boxes of cereal that must be purchased?
Answers
The expected number of boxes of cereal that must be purchased to obtain at least one of each of the four different prizes is 1.
Let X be the number of boxes of cereal that need to be purchased to obtain at least one of each of the four different prizes. We want to find E(X), the expected value of X.
To do this, we can use the concept of the geometric distribution. The probability of obtaining a new prize in a box of cereal is given by:
p = 4/4 = 1 (since there are four different prizes)
The probability of not obtaining a new prize in a box of cereal is
q = 1 - p = 0
Therefore, X follows a geometric distribution with parameter p = 1. The expected value of a geometric distribution with parameter p is
E(X) = 1/p
So in this case, we have
E(X) = 1/1 = 1
This means that on average, the family will need to purchase one box of cereal to obtain at least one of each of the four different prizes.

We will take a random sample of 20 American adults and ask them the question. Then the sampling distribution of the sample proportion of people who answer yes to the question is a binomial distribution.
What is a binomial distribution?A binomial distribution is a statistical distribution that represents the likelihood of one of two outcomes in a sequence of independent trials. Binomial distributions can be used to model a variety of phenomena, including flipping coins, rolling dice, and performing multiple independent experiments.
The probability of getting k successes in n trials in a binomial distribution with probability of success p and probability of failure q is given by the following formula:P (k) = nCk * p^k * q^(n-k)Where nCk is the binomial coefficient, which represents the number of ways to select k items from a set of n items without regard to order.

Answer:
[tex]2 \sqrt{61} \: in[/tex]
Step-by-step explanation:
Use the Pythagorean theorem (assume, that the length of hypotenuse is x):
[tex] {x}^{2} = {10}^{2} + {12}^{2} = 100 + 144 = 244[/tex]
[tex]x > 0[/tex]
[tex]x = \sqrt{244} = 2 \sqrt{61} [/tex]
if the area of a circle is less than $60\pi$ square inches, what is the greatest possible integer value in inches of the radius of the circle?
Answers
The greatest possible integer value of the radius of the circle is 7 inches.
The area of a circle is given by the equation[tex]$A = \pi r^2$[/tex]. We know that the area is less than [tex]$60\pi$[/tex] square inches, so the equation can be written as [tex]$60\pi > \pi r^2$[/tex]. We can solve for the radius by dividing both sides by [tex]$\pi$[/tex], which gives us [tex]$60 > r^2$[/tex]. Taking the square root of both sides gives us [tex]$r < \sqrt{60}$[/tex], which is approximately 7.74 inches. Therefore, the greatest possible integer value of the radius of the circle is 7 inches.
To explain this further, we can start with the equation for the area of a circle, which is[tex]$A = \pi r^2$[/tex]. Since the area is less than [tex]$60\pi$[/tex]square inches, this equation can be rewritten as[tex]$60\pi > \pi r^2$[/tex]. We can then divide both sides by [tex]$\pi$[/tex] to get [tex]$60 > r^2$[/tex]. Taking the square root of both sides gives us [tex]$r < \sqrt{60}$[/tex]. This result can then be rounded down to the nearest integer, which is 7. Therefore, the greatest possible integer value of the radius of the circle is 7 inches.

$800 deposit for 24 months earned $200 in interest
Answers
Answer:
The rate of interest applied for compound interest is 24.5 %
The rate of interest applied to simple interest is 37.5 %
Step-by-step explanation:
Given as :
The Principal amount that is deposited = $ 800
The Time period = 24 months = 2 years
The Interest earn = $ 200
Let the rate of interest = R %
So, The Amount = Principal deposited - interest earn
Or, A = $ 800 - $ 200
∴ Amount = $ 600
From compounded method
Amount = Principal ×
Or, $ 600 = $ 200 ×
Or, =
Or, 3 =
Or, = (1 +)
Or, 1.245 = (1 +)
or, 1.245 - 1 =
or, 0.245 × 100 = R
So, the rate is = 24.5 %
Hence The rate of interest applied fro compound interest is 24.5 % Answer
From Simple Interest method
Simple Interest =
Or, $ 600 =
Or, $ 600 × 100 = $ 800 × R × 2
Or, R =
∴ R = 37.5 %
So, The rate is 37.5 %
Hence The rate of interest applied to simple interest is 37.5 % Answer
