Step-by-step explanation:

So, the uncle has $3000.

The Oldest Niece gets double what the Younger Niece gets half her amount. The nephew gets the total of these 2 combined.

The Youngest Niece gets $500.

500x2=1000

The Oldest Niece gets $1000.

1000+500=1500

The Nephew gets $1500.

1500+1000+500=3000

The expression for the phrase is 5 * (x - 6) = 24

The phrase is given as:

the product of 5 minus 6 has a result of 24

Products means *

So, we have

5 * (x minus 6) has a result of 24

x minus 6 means x - 6

So, we have

5 * (x - 6) has a result of 24

has a result of 24 means = 24

So, we have

5 * (x - 6) = 24

Hence, the expression for the phrase is 5 * (x - 6) = 24

the answer is good

Answer:

Step-by-step explanation:

Step One

The first step is to find the value of n.

h(x) = n(x) + 28

h(3) = 1

That means that 1 is on the left and wherever there is an x on the right, it will have a value of 3

Step Two

Substitute values

1 = n(3) + 28                  

Step 3

Solve

1 = 3*n + 28                       Subtract 28 from both sides

1 + - 28 =  3n                     Combine

-27 = 3n                             Divide both sides by 3

-27/3 = 3n/3

- 9 = n

Step 4

Let x = - 6 on the right side of the original equation.

h(-6) = 3*-6 + 28

h(-6) = -18 + 28

Answer

h(-6)  = 10

Step-by-step explanation:

The number of hamburgers sold on Wednesday is 141 and the number of cheeseburgers sold on Wednesday is 423

Although a part of your question is missing, you might be referring to this full question: On Wednesday, a local hamburger shop sold a combined total of 564 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Wednesday?

Total number of burgers sold on Wednesday = 564

Let the number of hamburgers sold on Wednesday be x

Let the number of cheeseburgers sold on Wednesday be y

Formulating the equation we get:

x + y = 564-----(1)

It is also given that, the number of cheeseburgers sold was three times the number of hamburgers. So,

y = 3x

Substituting y = 3x in equation (1) we get

x + 3x =564

4x = 564

x = 141

Putting x = 141 in equation (1) we get

y = 423

So, the number of hamburgers sold is 141 and the number of cheeseburgers sold is 423

Answer:

24 books can fit on 1 shelf.

Step-by-step explanation:

Question: Juan has 28 paperback books that measure 1 and 1/4 inches each. How many books will fit on one shelf if each shelf measures 30 inches?

Step-by-step:

We know that each book is 1 and 1/4 inches each. It might be easier to convert the fraction into a decimal.

1/4 inches is 1 divided by 4 which equals to 0.25 inches

1 inch + 0.25 inches = 1.25 inches

so, 1 and 1/4 inches = 1.25 inches

To find out how many books fit on a shelf, we need to find: length of 1 bookshelf divided by length of 1 book

We know that one bookshelf is 30 inches and 1 book is 1.25 inches

so, 30/1.25 or 30 divided by 1.25 = 24

Therefore, 24 books can fit on 1 shelf.

Answer:

x = 3

Step-by-step explanation:

The coordinates of the vertex P is calculated as (0,2√3).

The distances among two points as a characteristic of their coordinates are given by an algebraic expression (like coordinate system).

Now, according to the given question;

The coordinates of the points Q and R  is given as;

Q and R as (-2, 0) and (2, 0).

Now, as the all three points P,Q and R forms the equilateral triangle. Then, the distance of each side or the distance between two consecutive points are equal.

Calculate the distances between the points;

QR = √(2 + 2)² + (0 - 0)²

QR = 4

Let the coordinated of P be (x, y);

Then,

QP = √(x + 2)² + (y + 0)²

QP = QR = 4

4 = √(x + 2)² + (y)²     ........(equation 1)

RP = √(x - 2)² + (y + 0)²

RP = QR = 4

4 = √(x - 2)² + (y)²     ........(equation 2)

Equating equation 1 and 2.

√(x + 2)² + (y)² = √(x - 2)² + (y)²

Squaring both side;

(x + 2)² + (y)² = (x - 2)² + (y)²

x² + 4 - 4x + y² = x² + 4 - 4x + y²

Simplifying the equation;

x = 0.

Put the value of x in equation 1;

4 = √(x + 2)² + (y)²

y = 2√3.

Therefore, the coordinates of the point P are found to be (0, 2√3).

The coordinates of K are (8,3).

There is a line segment JK with M as its midpoint. This means the length of JM = length of MK.

Also the coordinates of J is (-4,7) and the coordinates for M are (2,5).

As M is the midpoint, the x-distance and y-distance between (-4,7) and (2,5) are same as that between (2,5) and K.

x- distance between (-4,7) and (2,5) = 2- (-4) = 6

So x- coordinate of K = 2+6 = 8

y-distance between (-4,7) and (2,5) = 5-7 = -2

So y-coordinate of K = 5+(-2) = 3

The correct option is the last one:

"Cousin; The distance is the absolute value of the difference of the numbers lined up with the beginning and the end of the object."

Now, remember that a rule is equivalent to a number line.

Now, suppose that you are measuring an element with a length of 16 centimeters.

If you measure it by lining up one of the ends of the element with the zero, then the other end will be at the line number 16.

And if you line it up from a different number, let's say 3cm, then the other end of the object (which still measures 16cm) will be at 19cm.

In both cases, to find the measure of the object that you are measuring with the ruler, you need to find the difference between the two numbers on the ruler that line up with the object ends.

If you line up with the zero, you need to subtract zero, so the measure is easier:

16cm - 0cm = 16cm

If you line up with other number, like the 3 in this case, you need to perform the subtraction:

19cm - 3cm = 16cm

In both cases, we will get the same measure. So your cousin is correct, and the correct option is the last one:

Cousin; The distance is the absolute value of the difference of the numbers lined up with the beginning and the end of the object.

Hence ,  the difference in length between segments AB and AD is 1.17 units .

The diagram of the given question is given below .

Applying sin rule in triangle ABC , we get

sin(x°) = AC/AB

sin(45°) = 4 / AB

1 /√2 =  4 / AB

AB = 4√2

AB ≈ 5.657

Similarly, apply sin rule  in triangle ACD, we get

sin(y°) = AC /CD

sin(63°) = 4 / CD

AD = 4.489

Now distinction in lengths of AB and AD = 5.657 - 4.489

                                                                     = 1.168

A continuous function in mathematics is one that causes the value of the function to continuously vary as the input changes over time. This indicates that there aren't any discontinuities or sudden changes in value. In other words, a function is continuous if and only if its graph is devoid of any gaps or breaks. It is simple to predict where it won't be continuous for many functions. Where we have operations like division by zero or logarithms of zero, functions won't be continuous. Examples of continuous functions over the set of all real numbers are polynomial functions, exponential functions, and the sin and cosine graphs.
