Answer:

2.31

Step-by-step explanation:

1.65 * 1.4 = 2.31

Answer:

Erica has 51 action figures and Ricardo has 17 action figures.

Step-by-step explanation:

First, label your variables.

x=the number of action figures Erica has

y=the number of action figures Ricardo has

You know that they have 68 total action figures so x+y=68.

Erica has 3 times as many as Ricardo so 3y=x. Then solve for x and y.

x+y=68    3y=x   (Substitue 3y for x)

3y+y=68   (Then combine like terms)

4y=68  (Divide each side by 4)

y= 17

Now that you know that Ricardo has 17 action figures, you can plug 17 in for y in either equation to find x.

3(17)=x

x=51

To check your answers, you can plug them back into the original equations.

Answer:

Erica:51 action figures; Ricardo: 17 action figures

Reason:

68/4=17

17*3=51<- this is the amount of action figures that Erica has.

17 <-this is the amount of action figures that Ricardo has.

17 (Ricardo) + 51 (Erica) = 68 (total amount)

The statement that shows a discrepancy between the check register and bank statement is: C. Gavin: The balance in his check register is $500 and the balance in his bank statement is $510.

The check register shows a balance of $500, while the bank statement shows a balance of $510.

In the case of Gavin, where the balance in his check register is $500 and the balance in his bank statement is $510, there is a $10 discrepancy between the two.

A possible explanation for this discrepancy could be outstanding checks or deposits that have not yet cleared or been recorded in either the check register or the bank statement.

For example, Gavin might have written a check for $20 that has not been cashed or processed by the bank yet. Therefore, the check register still reflects the $20 in his balance, while the bank statement does not show the deduction. Similarly, Gavin may have made a deposit of $10 that has not yet been credited to his account in the bank statement.

Answer:

Each apple pie requires 8 apples, and each apple tart requires 4 apples.

Step-by-step explanation:

We see that both Pamela and Nicole bake the same amount of apple pies, but different amounts of apple tarts. Because of this, we can subtract the two to try to figure out the amount of apples for each apple tart. We subtract 68 from 76, giving us 8. Nicole baked 9 apple tarts, while Pamela baked 7, and 9-7=2. So we can bake two apple tarts with 8 apples, so one apple tart requires 4 apples (we divide by 2). Now that we know the amount of apples per each apple tart, we multiply 7 apple tarts that Pamela made by 4 apples, giving us 28. We subtract that from the total amount of apples Pamela used, which was 68, giving us 40. From this we can deduct that 5 apple pies need 40 apples, and we divide by 5, giving us 1 apple pie requires 8 apples.

The amount of time it takes students to get ready is more variable than the amount of time it takes teachers to get ready.

It is not possible to determine the specific difference in minutes between the two groups based solely on the given box plots.

Comparing the two box plots, we can make the following accurate statements about the two data sets:

The typical student takes longer to get ready for school than the typical teacher:

This statement is not supported by the box plots.

The line dividing the box in the student box plot is at 16, indicating that the median (typical value) for students is 16 minutes.

In contrast, the line dividing the box in the teacher box plot is at 25, indicating that the median for teachers is 25 minutes.

Therefore, the typical teacher takes longer to get ready for school than the typical student.

The amount of time it takes students to get ready is more variable than the amount of time it takes teachers to get ready:

This statement is supported by the box plots.

The whiskers of the student box plot range from 10 to 30, indicating a larger spread of data compared to the teacher box plot, where the whiskers range from 15 to 50.

This suggests that the amount of time it takes students to get ready is more variable than the amount of time it takes teachers.

It typically takes teachers 9 minutes longer than students to get ready for school:

This statement is not supported by the box plots.

The box plot does not provide information about the specific difference in minutes between the two groups.

While we can see that the medians of the two box plots are different, we cannot determine a specific numerical difference such as 9 minutes.

Therefore, the accurate statements comparing the two data sets are:

The typical teacher takes longer to get ready for school than the typical student.

The amount of time it takes students to get ready is more variable than the amount of time it takes teachers to get ready.

6x + 3y=48

5x+y= 28

these functions are lines.  "Solving a system of questions" means to find the point where they intersect, where the x's are the same and the y's are the same.

You want to multiply an entire equation to eliminate a variable.

6x + 3y=48

5x+y= 28

6x + 3y=48     multiply the 2nd equation by -3 so you can eliminate the y's

-3(5x+y= 28)   multiply all terms by -3

6x + 3y=48    

-15x-3y= -84       add like terms of the equations  and the y goes away

-9x       = -36        divide both sides by -9 to solve for x

The equilibrium price for the given videotape is $24. At this price, the quantity supplied and the quantity demanded will be equal, resulting in a market equilibrium.

To find the equilibrium price, we need to set the quantity supplied equal to the quantity demanded and solve for the price. The quantity supplied is given by the supply equation p = (1/3)q^2, and the quantity demanded is given by the demand equation p = (-1/3)q^2 + 48.

Setting the quantity supplied equal to the quantity demanded, we have (1/3)q^2 = (-1/3)q^2 + 48. Simplifying the equation, we get (2/3)q^2 = 48. Multiplying both sides by 3/2, we obtain q^2 = 72.

Taking the square root of both sides, we find q = √72, which simplifies to q = 6√2 or approximately q = 8.49.

Substituting this value of q into either the supply or demand equation, we can find the equilibrium price. Using the demand equation, we have p = (-1/3)(8.49)^2 + 48. Calculating the value, we get p ≈ $24.

Therefore, the equilibrium price for the given videotape is approximately $24, where the quantity supplied and the quantity demanded are in balance, resulting in a market equilibrium.

The property of adaptive immunity enables a person to have the chicken pox when he or she is six years old and still be immune to chicken pox at age 45 exists Memory.

Specificity and memory are two crucial properties that determine adaptive immunity. Both specificity and memory pertain to the adaptive immune system's capacity to recognize and attack certain diseases, as well as to promptly react to pathogens to which it has already been exposed.

Adaptive immunity can offer an enduring defense, perhaps for the duration of a person's lifespan. In certain circumstances, such as with chickenpox, it does not confer permanent protection; for instance, a person who recovers from measles is now protected against measles for the rest of their life.

Specificity, diversity, specialization, memory, and self/non-self identification are the immunologic characteristics that define adaptive immunity, and these cells both create and show antigen-binding cell surface receptors.

Given, (1, 3), (6,3), (6, 6) and (1, 6) are the vertices of a rectangle, the width is 1 unit shorter.

A rectangle is a quadrilateral with the four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal (360°/4 = 90°). A square is a rectangle with the four equally long sides. Oblong is occasionally used to describe a rectangle that isn't square. Rectanglen is the symbol for a rectangle having the vertices ABCD. ABCD in PNG.

Rectangulus, a combination of rectus (as an adjective, right, proper), and angulus, is the source of the English word rectangle (angle).

A crossed rectangle is a quadrilateral that is formed by the intersection of two diagonals and the two opposite sides of a rectangle (therefore only two sides are parallel). Although opposite angles are equal, it is a specific example of an antiparallelogram in which the angles are not all right angles and equal. There exist so-called rectangles in other geometries, including spherical, elliptic, and hyperbolic ones, with opposite sides of equal length and equal angles that are not right angles.

Many tiling issues use rectangles, like tiling the plane with rectangles or tiling a rectangle with polygons.

By plotting given points in the coordinate plane,

We get rectangle ABCD having vertices,

The volume of a rectangular prism is V = lwh, and its surface area is SA = 2lw + 2lh + 2wh.

Surface area refers to the total area that covers the exterior part of an object. It is usually measured in square units and is commonly used in geometry and engineering. To calculate the surface area of a 3D object, you need to add up the areas of all the faces of the object. The Course 3 Chapter 8 Volume and Surface Area review focuses on understanding how to calculate the volume and surface area of various 3-dimensional shapes, such as cylinders, prisms, and pyramids. The volume of a shape is the space it occupies, while the surface area is the total area covering the shape's exterior. To find the volume and surface area of different shapes, you'll use specific formulas. For example, the volume of a cylinder is V = πr²h, and its surface area is SA = 2πrh + 2πr². Similarly, the volume of a rectangular prism is V = lwh, and its surface area is SA = 2lw + 2lh + 2wh. By mastering these formulas and applying them to various problems, you can accurately determine the volume and surface area of 3-dimensional shapes.
