Jessica gets more rocks to skip across the surface of the pond than Henry.

To determine who gets more rocks to skip across the surface of the pond, we will take the ratio of rocks that skip to rocks that are thrown for each person.

For Henry, the ratio is 5 rocks that skip to 9 rocks thrown i.e 5/9.

For Jessica, the ratio is 7 rocks that skip to 12 rocks thrown i.e 7/12.

Now to compare the ratios, we need to convert them into like fractions. We will do this by making the denominations of both the fractions same.

We will multiply the numerator and denominator of Henry's ratio by 12 to get -

5/9 x 12/12 = 60/108

Also, we will multiply the numerator and denominator of Jessica's ratio by 9 to get -

7/12 x 9/9 = 63/108

Comparing the numerators we get 60<63.

This implies that 60/108 < 63/108.

Therefore, Jessica gets more rocks to skip across the surface of the pond.

The bar representing her 7-day vacation will have a class width of 16 - 22 and a height of 1.

The frequency distribution of a collection of data reveals how frequently each unique value appears.

The most typical graph for displaying frequency distributions is a histogram. Although it closely resembles a bar chart, there are significant variances.

In the given histogram class width(horizontal width)  represents the number of days and frequency(vertical height) represents the number of vacations taken.

Therefore, The 7-day vacation yet she took this summer will be represented by a bar having a class width 16 - 22 and a height of 1.

Parallelograms are quadrilaterals with two sets of parallel sides

Slope Formula: y2-y1/x2-x1

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.

KL: 12-7/6-2 = 5/4

LM; 13-12/13-6 = 1/7

A circle is a two-dimensional figure with a radius and circumference of 2πr.

The area of a circle is πr².

We have,

Centre of the circle = (-7, -15)

The equation of a circle is r² = (x - h)² + (y - k)²

Where (h, k) is the center of the circle.

Now,

The answer of [tex]\sqrt[4]{125a^{4} }[/tex] is 3.34a. The solution has been obtained by using the concept of exponents.

What is an exponent?

The exponent of a number shows that how many times a particular number has been multiplied by itself. For instance, the number 2^4 means that we are multiplying the number 2 itself by four times. It is enlarged to 2*2*2*2. An exponent is also known as a number's power. One may use a whole number, fraction, negative number, or decimal.

We are given [tex]\sqrt[4]{125a^{4} }[/tex]

This can be also written as (125a^4)^1/4

Splitting the power, we get

The monthly payment during the initial period is  about $1,682.94

The type of loan Jackie obtains is an Adjustable Rate Mortgage, ARM, loan, which is a 4/2 ARM

The introductory interest rate of 5% is fixed for the first 4 years, and will be adjusted every 2 years after the first four years.

Let us assume that m represents the initial monthly payment.

[tex]M=\frac{P.(\frac{r}{12} ).(1+\frac{r}{12} )^n}{(1+\frac{r}{12} )^n - 1}[/tex]

where, M is the monthly payment during the initial period

P is the amount on loan

Step-by-step explanation:3.22$ in the USA

OC (x+1)(x-8)(4)=56 indicates that the volume of the box is 56 in³ because it takes into account the length of the sides after the four corners were cut off, and the height of the box which is 4 in. The equation can be written as (length of sides)(width of sides)(height) = volume.

A volume is a three-dimensional space that contains a specific amount of material, which is commonly measured in liters, cubic meters, or gallons. It is frequently used to calculate the capacity of containers like tanks, bottles, and barrels. Volume may also refer to the quantity of space occupied by an item, such as the volume of a room or the volume of a sphere.

In the given question, OC is the correct answer: (x+1)(x-8)(4)=56. This equation reveals that the volume of the box is 56 [tex]in^{3}[/tex] because it considers the length of the sides after the four corners were taken off, which are (x+1) and (x-8), as well as the height of the box, which is 4 in.

The long division problem can be used to prove the formula for factoring the difference of two perfect cubes (a-b)(a²+ab+b²).

The difference of two perfect cubes: a³-b³  = (a-b)(a²+ab+b²)

let the two perfect cubes be a³ and b³. Factoring the  difference between these two perfect cubes we have: a³ - b³

First, we need to factorize (a-b)³:

(a-b)³ = (a-b) (a-b)²

(a-b)³ = (a-b)(a²-2ab+b²)

(a-b)³ = a³-2a²b+ab²-a²b+2ab²-b³

(a-b)³ = a³-b³-2a²b-a²b+ab²+2ab²

(a-b)³ = a³-b³ - 3a²b+3ab²

(a-b)³  = (a³-b³) -3ab(a-b)

Then we will make a³-b³ the subject of the formula from the result equation;

a³-b³ =  (a-b)³+ 3ab(a-b)

a³-b³  = a-b{(a-b)²+3ab}

a³-b³  = a-b{a²+b²-2ab+3ab}

a³-b³  = (a-b)(a²+b²+ab)

a³-b³  = (a-b)(a²+ab+b²)

The long division problem that can be used is (a-b)(a²+ab+b²).

As per the given mortgage, the remaining balance be after the first 5 years is $678125

Here Kathy and Jake are purchasing a house and are financing $465,000. The mortgage is a 20-years 5/1 ARM at 3. 5% with a 2/7 cap structure.

As we know that the formula for the calculation is written as

=> (Mortgage X Rate)/ 12 months

And then we have to subtract the Monthly PI payment from monthly interest on payment.

When we apply the value on it, then we get,

($465,000 x 3.5)/12

Paul's pig pen has a width of 2 feet and an area of 16 square feet is the true statement.

The area of Rectangle is length times of width.

This is a simple calculus problem but it can be solved without calculus, as follows:

let L=length of the pen and W = width

2(L + W) = 20  

L + W = 10

L = 10 - W

Let A = area of the pen

A = Length × Width = 10W - W²

Sketch this parabola which has a positive maximum which occurs at W = 10/2

This means the area is maximum when w = 2, in other words the maximum area occurs when the rectangle is a square.

Answer: An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. We can call this constant difference "d".

In this sequence, we can see that the difference between consecutive terms is -6x - 5.

The 9th term of an arithmetic sequence can be found by using the formula:

a_n = a_1 + (n-1)d

Where a_n is the nth term of the sequence, a_1 is the first term of the sequence and d is the common difference.

Given the sequence -5x + 2, -11x - 3, -17x -8, ...

The 9th term is:

-5x + 2 + (9-1) (-6x-5) = -5x + 2 - 48x - 40 = -53x -38

Therefore the 9th term of the arithmetic sequence is -53x -38.

Answer: The graph of f(x) = 2^x and g(x) = 2^x +2 are the same.

Explanation: The functions f(x) = 2^x and g(x) = 2^x + 2 are identical. The only difference between them is the constant term in the second function. This constant term does not change the shape, direction or the relative position of the graph of the function, it only shifts the graph along the y-axis. Because both functions have the same base, the graphs will have the same shape, direction and relative position, regardless of the constant term.

Answer:

w = 11 , x = 25

Step-by-step explanation:

for Δ ABC ≅ Δ TUV, then corresponding sides must be congruent, that is

AB = TU and BC = UV ( using these to create 2 equations )

- 9x + 20w + 89 = 4w + x + 15 ( subtract 4w + x + 15 from both sides )

- 10x + 16w + 74 = 0 → (1)

and

x + w + 41 = - 18w + 11x ( subtract - 18w + 11x from both sides )

- 10x + 19w + 41 = 0 → (2)

multiplying (2) by - 1 and adding to (1) will eliminate x

10x - 19w - 41 = 0 → (3)

add (1) and (3) term by term to eliminate x

0 - 3w + 33 = 0 ( subtract 33 from both sides )

- 3w = - 33 ( divide both sides by - 3 )

w = 11

substitute w = 11 into either of the 2 equations and solve for x

substituting into (1)

- 10x + 16(11) + 74 = 0

- 10x + 176 + 74 = 0

- 10x + 250 = 0 ( subtract 250 from both sides )

- 10x = - 250 ( divide both sides by - 10 )

x = 25

thus the values x = 25 and w = 11 will make the triangles congruent
