Madelyn reads at the rate of 33.75 pages per hour.

Here rate is defined as the number of pages read per hour. Rate or unit rate is defined as the quantity that is done in 1 unit of time(second, minute or hour). Distance per time is called speed. Velocity per time is called acceleration.

Here it is given Madelyn reads 45 pages in [tex]1\frac{1}{3}[/tex] hours.

Now to find the unit rate we have to divide the number of pages read in the total time taken to read 45 pages.

Unit rate= [tex]45\div 1\frac{1}{3}[/tex]

[tex]=45\div \frac{4}{3}\\=\frac{135}{4} \\=33.75[/tex]

12 posts are required to support a straight fence 300 feet long if a post is placed every 25 feet.

The given question can be solved using division. We are given that 25 feet is covered by 1 post. So, we will simply find the number of posts that will cover the 300 feet long fence. Now, calculating the number of posts as shown in steps below -

Number of post that covers 25 feet = 1

So,  300 feet will be covered by number of posts = (1÷25)×300

Performing multiplication and division to find the number of posts required to cover 300 feet long fence

Number of posts required to cover 300 feet long fence = 12 posts

Hence, 12 posts are required to cover 300 feet long fence.

Using a system of equations, it is found that:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

The total invested is of $36,000, hence:

x + y = 36000.

The amount invested in bonds is to to exceed that in CDs by $5,000, hence:

x = y + 5000.

Replacing in the first equation:

y + 5000 + y = 36000.

2y = 31000

y = 15,500.

Answer:

5(3n - 4)(3n - 10)

Step-by-step explanation:

15n² - 110n + 200 ← factor out 5 from each term

= 5(3n² - 22n + 40) ← factor the quadratic

consider the factors of the product of the coefficient of the n² term and the constant term which sum to give the coefficient of the n- term.

product = 3 × 40 = 120 and sum = - 22

the factors are - 12 and - 10

use these factors to split the n- term

3n² - 12n - 10n + 40 ( factor the first/second and third/fourth terms )

3n(n - 4) - 10(n - 4) ← factor out (n - 4) from each term

(n - 4)(3n - 10)

then

15n² - 110n + 200 = 5(n - 4)(3n - 10)

Answer:

Hello,

[tex]15(n^2-\dfrac{22}{3}x +\dfrac{40}{3} )=15(n-\dfrac{10}{3} )(n-4)=5*(3n-10)(n-4)[/tex]

Answer:

-9.5

Step-by-step explanation:

The function F to be used to convert the temperature is; F = ⁹/₅C + 32

From the given information, we can tag the coordinates as;

(32,0) and (212,100)

Thus, the slope is calculated as;

m = (100-0)/(212-32)

m = 100/180

m = 5/9

The intercept is;

c = y - mx

c = 0 - (5/9)(32)

c = 0 - 160/9

c = -160/9

The line equation is;

y = 5/9 x + (-160/9)

y = 5/9 x - 160/9

y = 5/9 (x - 32)

Let x = F and y = C and we have;

We get the expression for the statement "The sum of eight and half of a number" as (16 + x) / 2.

We are given a statement:

The sum of eight and half of a number.

We have to form an expression for the same.

An expression means a combination of numbers and variables.

Let the number be a variable say x.

Now we need the half of a number.

1 / 2 of x = x / 2

Now we need the sum of 8 and x / 2.

So, it will be:

8 + x / 2

= (16 + x) / 2

Therefore, we get the expression for the statement "The sum of eight and half of a number" as (16 + x) / 2.

We need to know about cube-root function and reflection to solve this problem. The function is f(x)=[tex]-\sqrt[3]{x-4}[/tex]

A cube-root function is the inverse of a cubic function, a cubic function can be given by f(x)=[tex]x^{3}[/tex], the inverse of this is a cube-root function which can be given by f(x)=[tex]\sqrt[3]{x}[/tex] with vertex at (0,0). The general formula for a cube root function is given be

f(x)=a[tex]\sqrt[3]{x-h} +k[/tex] where a is the measure of how horizontally compressed the graph is and (h,k) is the vertex of the graph. In the question we have to find a cube root function which has been reflected about the y-axis, which means our a will be negative. The vertex of the graph is at (4,0) so (h,k) is (4,0). Thus the cube root function we need is

f(x)=-[tex]\sqrt[3]{x-4}[/tex]

Therefore we found the cube root function that has been reflected about y-axis and the vertex at (4,0) to be  f(x)=[tex]-\sqrt[3]{x-4}[/tex]

Part i) Simple interest = $600,000.00.

Part ii) Selling price = $2,900,000.00.

Part i) The formula for simple interest is;

SI = PRT/ 100

P = principal amount = $2,000,000.00.

R = rate of interest  = 15%

T = time in years = 2 years.

Put the value in the formula;

SI = ( $2,000,000 × 2 × 15)/100

On simplification;

SI = 600,000

Thus, the simple interest at the end of 2 years is $600,000.oo

Part ii) the selling price

Selling price = cost price + profit

Selling price = cost price + 45%of cost price

Cost price = $2,000,000.00

45%of cost price = 45× $2,000,000.00/100

45%of cost price = 900,000.00

Selling price = $2,000,000.00 + 900,000.00

Selling price = $2,900,000.00.

Small objects (polyhedrons) used as playing pieces for dice games and other gambling-related activities. The cube, the most popular type of die, has one to six tiny dots on each side (spots). The spots are positioned in the following traditional patterns: 1 and 6, 2 and 5, 3 and 4, so that spots on opposite sides always sum up to 7. The poker and crown and anchor dice, as well as many other types of dice with 4, 5, 7, 8, 10, 12, 16, and 20 sides, are examples of dice with different configurations of spots or other face designs. The majority of the time, dice are employed to generate a random outcome (usually a number or a mixture of numbers), and the mathematical probabilities depend on the physical characteristics and quantity of dice thrown.
