Kate need 3/4 cup of flour. She only ha two meauring cup, a 1/3 and a 1/8. Which cup hould Kate ue? Explain in word or a model

Answers

Answer 1

Kate need 3/4 cup of flour. She only ha two measuring cup, a 1/3 and a 1/8. The cup should Kate use is 1/8 .

The cup of flour she need is 3/4 that is 75% of the use.

There are two cups available 1/3 and 1/8

In percentages 1/3 can be 33.33%

And in percentages 1/8 can be 12.5%

The amount to be filled is 3/4 that is 75% so the cup that will be used for this is 1/8 that is 12.5% so that,

= 12.5 x 6

= 75

So we used 1/8 cup for 6 times we can get the 3/4 cup of flour.

A candle i 22 cm long. After burning for 11 minute, the candle i 5. 5 cm long. How much time will the candle take to burn out completely at the ame rate?

Answers

The candle will take nearly 33.2 minutes to burn out completely at the same rate.

To find the time that will take the candle to burn out completely, we have to calculate the total length of the candle and divide it by the rate at which the candle is burning.

Let us take the time it takes to burn the whole candle = T.

The total length of the candle = 22 cm.

The burning rate of the candle is 22 cm - 5.5 cm = 16.5 cm per 11 minutes.

So, T = 22 cm / (16.5 cm/11 minutes) = 22 cm * 11 minutes / 16.5 cm = 33.2 minutes.

Therefore, the candle will take nearly 33.2 minutes to burn out completely at the same rate.

if a data set contains two groups that each have 40 people in them, how many rows will the "data view" have?

Answers

The "data view" of a dataset with two groups that each contain 40 people will have 80 rows.

A data set is a collection of data that is organized and processed to provide useful information. In a data set, each row represents a single observation or record. In the case where a data set contains two groups, each group represents a separate set of observations or records.

If each group has 40 people, this means that there are 40 separate observations or records in each group. Therefore, the total number of rows in the "data view" of the data set will be equal to the sum of the number of rows in each group, which is 40 + 40 = 80.So, the "data view" of a data set with two groups that each have 40 people will have 80 rows, with each row representing a single observation or record from one of the two groups.

What is the present value of $10,000 per year in perpetuity at an interest rate of 10%?
A.$10,000
B.$100,000
C.$200,000
D.$1,000PV

Answers

The present value of $10,000 per year in perpetuity at an interest rate of 10% is $100,000. Therefore, correct answer will be B.$100,000.

This is because the present value of an annuity, or a series of payments, is equal to the sum of the present value of each payment. In this case, the payment is $10,000 and the interest rate is 10%. Therefore, the present value of each payment is $10,000/(1+0.1)^1, which is $9,090.

Since the payments are perpetual, the present value of the annuity is equal to the present value of each payment multiplied by the number of payments, which is infinite. Therefore, the present value of the annuity is $9,090 multiplied by infinity, which is $100,000.

if g(x)=3 x e^x find g^-1(4)

Answers

Answer: g(0) = 4

Step-by-step explanation:

Given that, g(x) = 3 + x + ex

g'(x) = 1 + ex > 0

⇒ g(x) is an increasing function.

g(0) = 3 + 0 + e0

g(0) = 3 + 1

g(0) = 4

When g(0) = 4, the inverse of the function g(x) = 3 + x + e^x is g^-1(4) = 0.

What is function?

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain. Originally, functions were the idealization of how a variable quantity depended on another quantity. A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2.

Here,

Given that, g(x) = 3 + x + e^x

g'(x) = 1 + e^x > 0

g(x) is an increasing function.

g(0) = 3 + 0 + e^0

g(0) = 3 + 1

g(0) = 4

Answers

No, the set s is not a basis for R3. A basis for R3 must contain three linearly independent vectors.

The set s only has three vectors, but these vectors are not linearly independent. To determine linear independence, we can take the set of vectors and put them into a matrix, then reduce the matrix to reduced row echelon form.

Let A be the matrix whose columns consist of the vectors in s:

A =

[tex]\begin{bmatrix} 0 & 4 & -8 \\ 4 & 0 & 20 \\ -1 & 3 & -11\end{bmatrix}[/tex]

When A is reduced to row echelon form, we see that the third row of A is a linear combination of the first two rows. This means that the vectors in s are linearly dependent, and thus s is not a basis for R3.

complete the table below given f(x)=x 3/√1−x−2

Answers

What do you mean by function?

A function is a mathematical object that assigns a unique output (or "value") to each input in its domain. It is a rule that takes an input (or "argument"), performs some operations on it, and returns a corresponding output. Functions are often written using the notation f(x), where x is the input, and f(x) is the corresponding output. For example, the function f(x) = x^2 maps the input value x to its square. Functions are a key concept in mathematics and are used to model various phenomena in science, engineering, economics, and more.

To complete the table, we need to evaluate f(x) for each value of x:

x -3.1 -3.01 -3.001 -2.999 -2.99 -2.9

f(x) undefined undefined undefined 2.8069 2.8068 2.8067

We can see that f(x) is undefined when x = -3.1, -3.01, and -3.001 because the square root of a negative number is undefined. For other values of x, we can evaluate f(x) by plugging in the values and simplifying:

f(-2.999) = (-2.999 + 3)/√(1 - (-2.999) - 2) = 0.001/√0.999 = 0.001/0.999 = 0.001 * (1/0.999) = 0.001 * 1.001 = 0.001001

Similarly, we can find f(-2.99) and f(-2.9) as follows:

f(-2.99) = (-2.99 + 3)/√(1 - (-2.99) - 2) = 0.01/√0.99 = 0.01/0.9950 = 0.01 * (1/0.9950) = 0.01 * 1.0050 = 0.01005

f(-2.9) = (-2.9 + 3)/√(1 - (-2.9) - 2) = 0.1/√0.9 = 0.1/0.9487 = 0.1 * (1/0.9487) = 0.1 * 1.0543 = 0.10543

So, rounding the results to four decimal places, we have:

x -3.1 -3.01 -3.001 -2.999 -2.99 -2.9

f(x) undefined undefined undefined 2.8069 2.8068 2.8067

The half-life of a radioactive kind of cerium is 32 days. How much will be left after 160 days, if you start with 57,728 grams of it?

Answers

After 160 days, approximately 873 grams of the radioactive cerium would be left.

How to calculate the amount of the substance left

The half-life of the radioactive cerium is 32 days, so after each 32-day interval, half of the remaining amount will decay.

We can use this information to determine the amount remaining after 160 days.

After the first 32 days, the amount of cerium left would be 57,728 grams * (1/2) = 28,864 grams.

After the second 32 days, the amount of cerium left would be 28,864 grams * (1/2) = 14,432 grams.

Continuing this process, after 160 days, the amount of cerium left would be:

57,728 grams * (1/2)^(160/32) ≈ 873 grams

Answers

All the components of the question are solved below.

(a) 2πd is not a valid expression to calculate a distance because d is not a distance, it is a position.

(b) x+Δr could be a valid expression to calculate a distance because x is a distance and Δr is a position difference, so their sum is also a distance.

(c) x+y2 is not a valid expression to calculate a distance because the units of x and y2 are not consistent with each other.

(d) x2+y2 is a valid expression to calculate a distance because both x and y are distances and their sum squared represents the Pythagorean theorem, which is commonly used to calculate distances in physics.

(e) A+z is not a valid expression to calculate a distance because A is an area and z is a distance, so their sum does not have a physical interpretation as a distance.

(f) vΔt2 is not a valid expression to calculate a distance because v is a velocity and Δt is a time difference, so their product does not have a physical interpretation as a distance.

(g) aΔt2 is a valid expression to calculate a distance because a is an acceleration and Δt is a time difference, and their product represents the displacement of an object under constant acceleration, which is a distance.

To get the measure of side NO of the rectangle LMNO, you will only need to divide side N'O' by the scale factor of 6. Then you'll get 4, which is the actual measure of side NO.

Dilation in math means changing the size of an object without changing its shape. The size of the object may be decreased or increased based on the scale factor. For instance, you can dilate a square of side 10 units to a square of side 15 units, but the shape remains the same.

We use dilation to expand and contract two-dimensional or three-dimensional shapes in geometry.

We're given a rectangle LMNO dilated by a scale factor of 6 to form rectangle L'M'N'O' and side N'O' measures 24. The measure of side NO can be found by dividing the measure of side N'O' by the scale factor. 26 : 6 = 4, so 4 is the measure of side NO.

The technician at the tore worked on the computer for 4. 25 hours so

t= 4.25

Based on the formula,

Charge for Total - charge for Part

=Charge of Labor =544.75 - 141 = 403.75

Therefore, 403.75/ 4.25 will give us the value for a single time T hours.

Calculate the sum or difference:

403.75/4.25

Multiply both the numerator and denominator with the same integer:

40375/425

Cross out the common factor:

$95

A component of the wage bill or payroll known as direct labour cost can be specifically and regularly ascribed to or related with the production of a good, a specific job order, or the delivery of a service. Additionally, we might say that it is the price of the labour performed by those employees who actually create the product on the assembly line.

2. Kimberly's family invested in a Certificate of Deposit (CD) for her when she was born. The interest is compounded quarterly. A. What will be the difference after 15 years if the CD is compounded semiannually rather than quarterly? b. What will be the difference after 15 years if the CD is compounded monthly rather than quarterly?​

Answers

The value of the CD will be an amount of $7487.01 if it is compounded annually for 15 years.

What is Compound interest?

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

To find the value of the CD in 5 years, you need to calculate the compound interest earned over 5 years.

The interest rate is 8% per year, so the interest rate per quarter is 8%/4= 2%.

The value of the CD at the end of each quarter can be calculated using the formula:

CD value at end of quarter = CD value x (1 + interest rate per quarter)

For example, at the end of the first quarter, the CD value would be:

CD value at end of first quarter = $3000 x (1 + 0.02) = $3060

You can repeat this process for each quarter to find the CD value at the end of 5 years.

After 5 years, there will have been 20 quarters (15 years x 4 quarters per year), so the CD value at the end of 15 years will be:

CD value at end of 15 years = $3000 x (1 + 0.02)⁶⁰ = $9843.09

To find the value of the CD if it is compounded annually for 15 years, we can use the same formula, but use the annual interest rate of 8% and the number of years of 15. The CD value at the end of 15 years will be:

CD value at end of 15 years = $3000 x (1 + 0.08)¹⁵ = $7487.01

suppose that 2.3% of men and 2.8% of women have night-blindness. assume the population consists of twice as many men as women. a person is chosen at random from the population and is known to have night-blindness. what is the probability that this person chosen is a woman?

Answers

The probability that a person chosen at random from the population and known to have night-blindness is a woman is approximately 3.78, or 378%.

Let's call the number of men in the population "m" and the number of women in the population "w". We know that m = 2w and that 2.3% of men have night blindness and 2.8% of women have night blindness.

Let's call the probability that a randomly chosen person with night-blindness is a woman "P(Woman)". We want to find the value of P(Woman).

We can use Bayes' Theorem to solve for P(Woman). Bayes' Theorem states that:

P(A | B) = P(B | A) * P(A) / P(B)

where P(A | B) is the probability of event A given that event B has occurred, P(B | A) is the probability of event B given that event A has occurred, P(A) is the probability of event A, and P(B) is the probability of event B.

In this case, A is the event that the person chosen is a woman and B is the event that the person chosen has night-blindness. So, P(A) is the probability that a randomly chosen person is a woman and P(B) is the probability that a randomly chosen person has night-blindness.

P(A) can be calculated as follows:

P(A) = w / (m + w) = w / (2w + w) = w / (3w) = 1/3

P(B) can be calculated as follows:

P(B) = (2.3% * m + 2.8% * w) / (m + w) = (2.3% * 2w + 2.8% * w) / (3w) = (4.6% + 2.8%) * w / (3w) = 7.4% / 3

Next, we need to find P(B | A), which is the probability that a randomly chosen person has night-blindness given that the person chosen is a woman. We know that 2.8% of women have night-blindness, so:

P(B | A) = 2.8%

Finally, we can use Bayes' Theorem to find P(A | B), which is the probability that a randomly chosen person is a woman given that the person chosen has night-blindness:

P(A | B) = P(B | A) * P(A) / P(B) = 2.8% * 1/3 / (7.4% / 3) = 0.28 / 0.074 = 3.78

So, the probability that a person chosen at random from the population and known to have night blindness is a woman is approximately 3.78, or 378%.

Therefore, The probability that a person chosen at random from the population and known to have night-blindness is a woman is approximately 3.78, or 378%.

Find the values of x and y if triangle PQR~ triangle STU.

Answers

Answer:

x° = 54

y = 14

Step-by-step explanation:

Sum of interior angles of a triangle = 180, therefore:

79 + 16 + m∠P = 180

m∠P = 180 - 79 - 16 = 54

m∠RPQ = m∠UST = x° = 54°

64/16 = 28/(y-7)    solve for y:

64(y-7) = (28)(16) = 448

y - 7 = 448/64 = 7

y = 7 + 7 = 14

The monthly payment is  $167.85.

The correct option is C.

What is a loan calculation formula?

The formula:

PV = PMT/i[1 - {1/(1+i)ⁿ]

PV denotes the loan sum.

PMT stands for "monthly payment," I for "interest rate" (interest rate % divided by 12), and "n" for the number of months (term of the loan in months)

Given:

A credit card holder owes $5,498 on a credit card with a 26.99% interest rate compounded monthly.

Assuming no additional purchases are made with the card.

PV = 5498

n = 60

i = 0.2699/12 = 0.02

PMT={PVi(1+i)ⁿ}/{(1+i)ⁿ−1}

PMT = {5498(0.02)(1 + 0.02)⁶⁰/{(1 + 0.02)⁶⁰ - 1}

PMT = $167.85

Therefore, PMT = $167.85
