The percent of change from 5/4 to 3/8 is a 70% decrease.

To find the percent of change, we need to determine the difference between the original amount and the new amount, and then divide that difference by the original amount and multiply by 100 to express the answer as a percentage.

Let's first convert both fractions to decimals:

5/4 = 1.25

3/8 = 0.375

Next, let's find the difference between the original amount (1.25) and the new amount (0.375):

1.25 - 0.375 = 0.875

Finally, let's divide the difference by the original amount and multiply by 100 to express the answer as a percentage:

(0.875 / 1.25) * 100 = 70

It would take the two boys working together 2.38 hours to clean the pool.

The formula for working out the time it would take two people to complete a job when working together is:

T(combined) = 1 / (1/T1 + 1/T2)

Where T1 is the time it takes one person to complete the job and T2 is the time it takes the other person to complete the job.

In this case, T1 is 4 hours for Kevin and T2 is 6 hours for Jerome.

To solve the equation:

T(combined) = 1 / (1/4 + 1/6)

T(combined) = 1 / (0.25 + 0.17)

T(combined) = 1 / 0.42

T(combined) = 2.38 hours

Step-by-step explanation:

The minimum number of (whole) dictionaries that you need to measure together is s ≤ 7.0 x 10⁻⁷

Measurement is the process of determining the size, amount, or degree of something, usually using an instrument or a tool.

To determine the thickness of one page in a dictionary, you can measure a number of dictionaries together and average the results.

To achieve an uncertainty of only 7.0 x 10-7 inches in your measurement of one page, you need to determine the minimum number of dictionaries that you need to measure together.

Let's assume that you have N dictionaries and the thickness of the i-th dictionary is xi. Then, the average thickness of one page is given by:

(x1 + x2 + x3 + ... + xN) / N = x

The uncertainty in the average thickness of one page is given by:

s = √(∑((xi - x_bar)²)/(N-1)) / √(N) = √(∑((xi - x_bar)²)/N²(N-1))

We want to find the minimum value of N such that the uncertainty in the average thickness, s, is less than or equal to 7.0 x 10⁻⁷ inches.

So, we have:

s <= 7.0 x 10⁻⁷

Complete Question:

1. You have a set of calipers that can measure the thicknesses of a few inches with an uncertainty of + 0.0050 inches. You measure the thickness of one Oxford American Dictionary (2096 pages) and get 2.51 in.

To find f(2) using synthetic division, we set up the synthetic division table with the coefficients of the polynomial:

2 │ 5  -13  4  -2

 │    10 -6 -2

 └───────────

   5  -3 -2  0

The last entry in the bottom row of the table gives the remainder of the division, which is f(2). Therefore, we have:

f(2) = 5(2)³ - 13(2)² + 4(2) - 2 = 40 - 52 + 8 - 2 = -6

The graph of the system has been attached below. The solution has been obtained by using linear inequality.

What is linear inequality?

If the equals relation were used in its place, a linear inequality would produce a linear equation.

We are given two inequalities as x+y < 1 and 5x + y > 4

For plotting the points, we need to find x and y

1. x+y < 1

So, let y be 0, then

⇒x < 1

This gives us the point as (1,0).

Now, let x=0, then

⇒y < 1

This gives us the point as (0,1).

From these two points, the graph for the inequality is drawn and represented by red line.

2. 5x + y > 4

So, let y be -1, then

⇒5x > 5

⇒x > 1

This gives us the point as (1,-1).

Now, let x=0, then

⇒y > 4

This gives us the point as (0,4).

From these two points, the graph for the inequality is drawn and represented by green line.

Hence, the graph of the system of linear inequalities is obtained.

The equation Ax = 0 has no free variables, so A has n pivot columns. Since A is square, the pivots must be on the main diagonal, so A is row equivalent to the n x n identity matrix Iₙ.

In order for the equation Ax = 0 to have only the trivial solution, there must be no free variables. This means that the matrix A must have n pivot columns. Since A is square, the n pivot positions must be in different rows, which means that the pivots must be on the main diagonal. This means that A is row equivalent to the n x n identity matrix Iₙ. To make it row equivalent, we can perform elementary row operations, such as adding or subtracting rows, or multiplying or dividing a row by a non-zero constant. Once we have done this, the matrix will be in echelon form and the main diagonal will be composed of all 1s. This means that A is row equivalent to Iₙ.

The  complete question: Suppose A is nˣn and the equation Ax=0 has only the trivial solution. Explain why A has n pivot columns and A is row equivalent to Iₙ

Choose the correct answer below.

A. Suppose A is nˣn and the equation Ax = 0 has only the trivial solution. Then there are no free variables in this equation, thus A has n pivot columns. Since A is square and the n pivot positions must be in different rows, the pivots in an echelon form of A must be on the main diagonal. Hence A is row equivalent to the nˣn identity matrix,  Iₙ.

B. Suppose A is nˣn and the equation Ax = 0 has only the trivial solution. Then there are no free variables in this equation, thus A has n pivot columns. Since A is square and the n pivot positions must be in different rows, the pivots in A must be on the main diagonal. Hence A is the nˣn identity matrix,  Iₙ.

C. Suppose A is nˣn and the equation Ax=0 has only the trivial solution. Then there are n free variables in this equation, thus A has n pivot columns. Since A is square and then pivot positions must be in different rows, the pivots in an echelon form of A must be on the main diagonal. Hence A is row equivalent to the nˣn identity matrix,  Iₙ

Answer:

AOC=360-130 = 230

ABC= 230/2=115

Answer:

∠ABC = 115∘

Step-by-step explanation:

∠ABC = 1/2 ∠AOC

(Angle subtended by a chord on major area is half of that subtended on center)

∴ ∠ABC = 1/2 x 130 = 65

ABCD is  a cyclic quadrilateral

Sum of opposite angles = 180∘

∴ ∠ABC + ∠AOC = 180∘

 ∠ABC + 65 = 180∘

 ∠ABC = 115∘

Answer: The force on an object is directly proportional to its acceleration, which means that if the force is increased, the acceleration will also increase, and if the force is decreased, the acceleration will decrease. This can be expressed mathematically as:

F = k * a

where F is the force, a is the acceleration, and k is a constant of proportionality.

We can use the given information to find the value of k:

30 N = k * 10 m/s^2

k = 3 N*s^2/m

Now we can use this value of k to find the acceleration when the force is 9 N:

9 N = 3 Ns^2/m * a

a = 3 Ns^2/m / 9 N

a = 1/3 m/s^2

Therefore, the acceleration of the object when the force is 9 N is 1/3 m/s^2.

Original Rectangle Length (cm) | Length After 21% Increase (cm)

120 | 144

50 | 61

150 | 180

Each new rectangle is 21% longer than the original, so to calculate the length after a 21% increase, we need to multiply the original length by 1 + 21%.

For the first rectangle (120 cm):

1.21 * 120 cm = 144.4 cm (rounded to 144 cm)

For the second rectangle (50 cm):

1.21 * 50 cm = 60.5 cm (rounded to 61 cm)

For the third rectangle (150 cm):

1.21 * 150 cm = 180.15 cm (rounded to 180 cm)

So the table with the length of each new rectangle would be:

Answer: To put the equation y - 4x = 17 in slope-intercept form, we need to isolate the y variable on one side of the equation and have the coefficient of x be the slope of the line and the constant term be the y-intercept.

Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.

Starting with the equation y - 4x = 17, we can isolate y by adding 4x to both sides:

y - 4x + 4x = 17 + 4x

y = 4x + 17

So, the equation in slope-intercept form is y = 4x + 17, where the slope (m) is 4 and the y-intercept (b) is 17.

Step-by-step explanation:

y-4x = 17

slope intercept= y= 4x + 17

The burgundy fabric:1.135 square yards

The yellow fabric: 0.307 square yards

The total yards of fabric will she have to buy 1.442 square yards.

The same attribute is expressed using a unit conversion, but in a different unit of measurement.

For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

Chelsea needs 1472 square inches of burgundy fabric and 399 square inches of yellow.

As, 1 yards= 36 inches

and, 1 square yards= 1296 inches

Then, 1472 square inches of burgundy fabric

= 1472/ 1296

= 1.135 square yards

and, 399 square inches of yellow.

= 399/ 1296

The total coins in Lauren's coin collection = 75

Let us assume that there are 'n' total coins in Lauren's coin collection.

She keeps 3 of the coins in her box, which is 4% of the collection.

This means that 4 percent of 'n' is equal to 3.

Using the percentage formula,

4 % of m = 3

m × (4/100) = 3

We solve above equation for m.

⇒ m × 4 = 3 × 100        ..........(multiply both the sides by 100)  

⇒ m × 4 = 300
