Answer:

$4

Step-by-step explanation:

We need to set up an algebraic expression to solve this problem:

 Let n= cost of a notepad

Let p= cost of a pen

 First set up an expression for Cynthia's purchase:

 cost of notepads*number of notepads + cost of pens*number of pens = total cost

 n*2 + p*3 = 40.30

 Rewrite as:

2n + 3p = 40.30

 Next, set up an expression for Annie's purchase:

 Here we will be using the same variables

  n*3 + p*5 = 61

 Rewrite as:

 3n + 5p =61

 Now, set up a system of equations:

 2n + 3p = 40.30

3n + 5p =61

 A system of equations can be solved in several ways, here I will use the addition/elimination method

For this method one of the variables must be able to be eliminated

Step 1: Pick a variable to eliminate

Here I will eliminate n

Step 2: make the selected variables in the equations equal and opposite so that they cancel out when the equations are added together

(2n + 3p = 40.30)(-3)

(3n + 5p =61)(2)

-6n - 9p = -120.90

6n + 10p = 122

Step 3: add vertically

-6n - 9p = -120.90

6n + 10p = 122

         p  =  1.10

Step 4: Figure out the other variable by inputting the answer you just got back into the original equation

2n + 3(1.10) = 40.30

2n + 3.30 = 40.30

      -3.30      37

         2n = 37

        /2     /2

         n = 18.5

One notebook = $18.50

One pen= $1.10

 18.50+1.10= $19.60

 2nd step

We must first set up an algebraic expression

 total=15 pencils

total=9 pens

 The total amount is the price of one pencil*15

 To figure out one pencil:

10 pencils are $24

1 pencil is $2.40

 Total= $36

 9 pens = 36

Therefore 1 pen is $4

Answer:

x = [tex]\frac{7}{10}[/tex]

Step-by-step explanation:

Given

4x - [tex]\frac{4}{5}[/tex] = 2 ( multiply through by 5 to clear the fraction )

20x - 4 = 10 ( add 4 to both sides )

20x = 14 ( divide both sides by 20 )

x = [tex]\frac{14}{20}[/tex] = [tex]\frac{7}{10}[/tex]

x=7/10

Step-by-step explanation:

4x-4/5=2

multiply all through by 5

20x-4=10

collect like terms

20x=14

divide all through by 20

x=14/20

x=7/10

The length of line height BC according to the given parameter is; 14√2.

It follows from the task content that the base edge length of the pyramid is 14 units.

On this note, it follows that length of the segment BC is given by Pythagoras theorem as;

BC² = 14² + 14²

BC = 14√2.

Answer:

It is y>-10

Step-by-step explanation:

i did it and i got it right.

The inequality that represents elevations above -10 meters is y > -10.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The inequality y > -10 means that the elevation y of a passage is greater than -10 meters.

This represents all the elevations of passages that are above -10 meters, which is the given condition in the problem.

If the elevation is exactly -10 meters or below, then it does not meet the condition of being above -10 meters.

Therefore, any elevation that is greater than -10 meters satisfies this inequality, and any elevation that is less than or equal to -10 meters does not.

Thus,

The inequality that represents elevations above -10 meters is y > -10.

Answer:

.2(x+1)(x+5)

Step-by-step explanation:

Well first lets start with the x intercepts which are -1 and negative 5 so the equation must be either -0.2(x+1)(x+5) or .2(x+1)(x+5)

Notice how the graph is going upwards this means the number in front of the equation -.2 or .2 must be positive making .2(x+1)(x+5) this is because if .2 was negative the graph would be going downwards

Answer:

65 passengers

At hour six, about 54 passengers will be on the boat.

A straight line that minimizes the gap between it and certain data is called a line of best fit. In a scatter plot containing several data points, a relationship is expressed using the line of best fit. It is a result of regression analysis and a tool for forecasting indicators and price changes.

Sum of X = 15

Sum of Y = 195

Mean X = 3

Mean Y = 39

The sum of squares (SSX) = 10

The sum of products (SP) = 50

Regression Equation = ŷ = bX + a

b = SP/SSX = 50/10 = 5

a = MY - bMX = 39 - (5*3) = 24

ŷ = 5X + 24

When x = 6,

we get ŷ = 5(6) + 24 = 54

Therefore, the approximate number of passengers is 54.

Step-by-step explanation:

A left skewed data is one which it's tail is to the left of the distribution. This means the data is negatively skewed. One of the difference various characteristics of a left skewed data wh in could help find an answer to the question is that, for a left skewed distribution, the mean of the data is lower lesser than other measures of center and the mean falls to the left side of de of the peak. Hence, to create a data that is left skewed, we add the value from the options which will decrease the initial value of Mean.

From. The options ; adding 34 and 32 will increase the value the mean.

However, adding 18 will decrease the value value of the initial mean and hence, shift to the left of the peak.

Answer:

[tex]\displaystyle x=\left\{\frac{\pi}{2}, \frac{7\pi}{6}, \frac{3\pi}{2}, \frac{11\pi}{6}\right\}[/tex]

Step-by-step explanation:

We are given the equation:

[tex](\sin(x)-\cos(x))^2=1+\cos(x)[/tex]

And we want to find all solutions for the equation within the interval [0, 2π).

First, we can expand. This yields:

[tex]\sin^2(x)-2\sin(x)\cos(x)+\cos^2(x)=1+\cos(x)[/tex]

From the Pythagorean Identity, we know that:

[tex]\sin^2(x)+\cos^2(x)=1[/tex]

Therefore:

[tex]-2\sin(x)\cos(x)+1=1+\cos(x)[/tex]

Simplify:

[tex]-2\sin(x)\cos(x)=\cos(x)[/tex]

Subtract cos(x) from both sides*:

[tex]-2\sin(x)\cos(x)-\cos(x)=0[/tex]

Factor:

[tex]\cos(x)\left(-2\sin(x)-1)=0[/tex]

Zero Product Property:

[tex]\cos(x)=0\text{ or } -2\sin(x)-1=0[/tex]

Solve for each case:

[tex]\displaystyle \cos(x)=0\text{ or } \sin(x)=-\frac{1}{2}[/tex]

Use the unit circle. So, our solutions are:

[tex]\displaystyle x=\left\{\frac{\pi}{2}, \frac{7\pi}{6}, \frac{3\pi}{2}, \frac{11\pi}{6}\right\}[/tex]

*Note that we should not simply divide both sides by cos(x) to acquire -2sin(x) = 1. This is because we do not know what the value of x is, and so one or may values of x may result in cos(x) = 0, and we cannot divide by 0. Hence, we need to subtract and factor and utilize the Zero Product Property.

Using the given percentage, we found that the total number of chocolate chip muffins sold is 80.

What is meant by percentage?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Frequently, it is indicated with the per cent sign, "%". If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word per cent means. A % is a number without dimensions and without a standard measurement. The value of "whole" in this relationship between portion and whole is always set at 100.

Given,

 the number of chocolate  chip muffins sold = 36

The 36 muffins is the 45% of the total muffins sold.

Let the total number of muffins sold be x.

Then using the given percentage, we find the total muffins sold.

Percentage = (required number of muffins sold/ total number sold) *100

45% = 36/x * 100

0.45 = 36/x

x = 36/0.45 = 80

Therefore using the given percentage, we found that the total number of chocolate chip muffins sold is 80.
