Estimate the amount of the tip by rounding the bill to the nearest dollar before calculating.

15% tip on a bill of $46.62

The amount of the tip is approximately...?

Answers

Hello there! 46.62 rounded to the nearest dollar is 47. That's because the tenths digit is greater than 5, so we round up from 6 to 7. The new number is 47. Now, we can multiply by 15% to find the approximate amount of the tip, because that will get us to 15% of the amount. 47 * 15% (0.15) is 7.05. The amount of the tip is approximately $7.05.

if 4 apples cost $3.04 how much does just one cost

Answers

the answer for this is: $0.76
If 4 apples cost $3.04, than one apple would cost .76 cents. 

So, we can assume all of the apples are the same price right? It doesn't matter about size or color because the problem doesn't tell us that. So, we can conclude one apple is the same prices as another.

Well, to figure out how much one apple costs, we can divide 3.04 by 4. This is because we have 4 apples so we can take that price of the 4 apples total and divide it by haw many apples the problem gives us.

So, 3.04 / 4 = .76

Hope this helped!
 

Which word sentence represents the equation?



6(x + 3) = 42



A. The sum of 3 and six times some number is 42.

B. Three plus 3 times some number is 42.

C. Six times some number plus 3 is 42.

D. Six times the sum of a number and 3 is 42.

Answers

Final answer:

The word sentence that represents the equation 6(x + 3) = 42 is option A: The sum of 3 and six times some number is 42.

Explanation:

The word sentence that represents the equation 6(x + 3) = 42 is option A. The sum of 3 and six times some number is 42.

To understand why, let's break down the equation step-by-step:

We have the expression (x + 3) in parentheses, which means that whatever number the student chooses to replace x with should be added to 3.Next, we multiply the entire expression (x + 3) by 6.The result of that multiplication should equal 42.

So, option A correctly expresses the equation by stating that the sum of 3 and six times some number is 42.

Describe why it might not be a good idea to use a key where each symbol stands for 1 in a picture graph

Answers

Final answer:

It is inefficient to use a key where each symbol represents the value 1 in a picture graph because it can make the graph cluttered and hard to interpret, especially with large data sets. Picture graphs should simplify visualization of data, yet remain clear and easily comprehensible.

Explanation:

Using a key where each symbol stands for 1 in a picture graph might not be a good idea because picture graphs are meant to represent larger sets of data visually and efficiently. If each symbol represents only 1, the graph could quickly become cluttered and hard to read, especially if the data set is large. This defeats the purpose of a picture graph, which is to provide a clear and simplified visual representation of the data. Moreover, the choice of symbols in a mathematical context is arbitrary; they are placeholders that have no intrinsic significance, and what matters is the concept they represent.

For instance, when dealing with large quantities, using symbols that represent 10, 100, or any other convenient large number makes the graph much more readable and helps to emphasize important relationships and comparisons between different data sets. Similarly, when using equations, symbols are used as stand-ins for numbers, and changing a symbol does not affect the underlying relationship they represent. Introducing more effective representations pictures the concept that equations capture. Likewise, the practicality of picture graphs can be compared to other types of graphs, like pie graphs, bar graphs, and line graphs, each of which serves a different purpose and has its own best use scenario.

Final answer:

Using a key where each symbol stands for 1 in a picture graph can make it cluttered and confusing, especially for large data sets. It is advisable to use symbols to represent larger values or to choose different types of graphs for readability and clear communication of the data's relationships.

Explanation:

Using a key where each symbol stands for 1 in a picture graph could be inadvisable in some situations. For large quantities, having one symbol represent a single unit could make the graph cluttered and difficult to read. It is more effective to have symbols represent larger, rounded values so the graph remains clear and interpretable. The use of symbols in mathematics and graphs is generally arbitrary, and they can be chosen to best represent the data being visualized. For example, in equations or graphs illustrating one-dimensional kinematics, symbols are chosen to present information on position, velocity, and acceleration over time in a way that makes relationships between these physical quantities easily understandable.



When considering how to best display data, it's crucial to think about readability and the ease of extracting useful information from the graph. If a picture graph with one symbol representing 1 becomes too complex, it might be better to opt for other types of graphs like bar graphs or line graphs, depending on the data's characteristics. Furthermore, the real purpose of graphs is to capture and represent relationships or trends, which is often better achieved with symbols that represent more suitable quantities, especially when dealing with large numbers.



The glossary of key symbols and notation in mathematics reaffirms the concept that the symbols themselves are not inherently meaningful, but are placeholders to facilitate understanding of the relationships and quantities they represent. Therefore, when creating picture graphs, the key chosen should enhance the viewer's ability to quickly grasp the depicted information.

A rug maker is using a pattern that is a rectangle with a length of 96 inches and a width of 60 inches. The rug maker wants to increase each dimension by a different amount. Let l and w be the increases in inches and the length and width. Write and simplify an expression for the perimeter of the new pattern.

Answers

Increasing the length by [tex]l[/tex] we have the new expression for the length as [tex]96+l[/tex]

Increasing the width by [tex]w[/tex], we have the new expression for the width as [tex]60+w[/tex]

Perimeter of a rectangle is given by adding all the sides, so we have

[tex]P = 96 + l+96+l+60+w+60+w[/tex]
[tex]P=192+2l+120+2w[/tex]
[tex]P = 312+2l+2w[/tex]

Solve for s.



2/3s+5/6s=21



Enter the answer, as a whole number or as a fraction in simplest form, in the box.
s =

Answers

2/3s+5/6s=21
If you do the problem without the variable the equation equals 1.5.
After I did that I divided 21 with 1.5 then it had come to a total of 14.
After that I decided to plug in 14 in the equation and the total came out to be 21.So s =14
Final answer:

To solve the equation 2/3s + 5/6s = 21, you first combine the fraction terms into 1.5s = 21, then solve for s by dividing both sides of the equation by 1.5, giving you s = 14.

Explanation:

To solve for s, you need to first combine like terms on the left-hand side of the equation 2/3s + 5/6s = 21.

To add these fractions, you first need to find a common denominator, which is 6 in this case. So, the equation becomes 4/6s + 5/6s = 21, which simplifies to 9/6s = 21 or 1.5s = 21.

Now you can solve for s by dividing both sides of the equation by 1.5, resulting in s = 21 / 1.5.

So, the solution for s is 14, which can be entered as a whole number.

What is an irrational number between 7.7 and 7.9?

and no, 7.8 is not irrational.

Answers

Alright, so what you do is take an irrational number, like π, and get it between 7.7 and 7.9. How? For example, if you wanted to get π between 10 and 10.1, we know that π is 3.14 something. If we added 6.9 to it,we'd have 10.04 something. Since the numbers after that 1, 0, and 0 are not changed, this is still irrational as you can still not represent π with integers. For example, if we had π/1, we can add 5/1 to it and we'd have (π+5)/1, which can be separated into π/1+5/1 - a irrational number added to a rational number is not rational (The proof for this can be learned in calculus). Good luck, and feel free to ask with further questions!

a jigsaw puzzle has edge pieces and inside pieces. the ratio 3:22. there are 924 inside pieces. calculate the total number of pieces in the puzzle

Answers

Okay. So, 924 pieces are inside. Let’s divide to see how many times 22 goes into 924. 924/22 = 42. So now, multiply 3 by 42 to do the same thing the opposite way. The product is 126. There are 126 edge pieces in the puzzle. You can do 126/924 to get the fraction in simplest form to be 3/22. To find the total number of pieces, add both numbers up. The sum of the two numbers is 1,050. There are 1,050 total pieces in the puzzle.

The jigsaw puzzle has a total of 1050 pieces, with 126 edge pieces and 924 inside pieces, based on the ratio 3:22 provided in the question.

To calculate the total number of pieces in the jigsaw puzzle, we need to use the given ratio of edge pieces to inside pieces, which is 3:22. If there are 924 inside pieces, and the ratio of edge pieces to inside pieces must remain constant, we can set up a proportion where the number of edge pieces is represented by x and the number of inside pieces by 924.

3:22 = x:924

To find the value of x, we can cross-multiply:

3 * 924 = 22 * x

This gives us :

2772 = 22x

Now, we can solve for x by dividing both sides of the equation by 22:

x = 2772 / 22

x = 126

This means there are 126 edge pieces. To find the total number of pieces in the jigsaw puzzle, we add the edge pieces to the inside pieces:

Total pieces = edge pieces + inside pieces = 126 + 924 = 1050

f(x)=-x^2+8x-20 find the min/max value

Answers

use the formula 
-b/2(a)

The maximum value of the quadratic function f(x)=-[tex]x^2+8x-20[/tex] is -4, which occurs at x=4. This value can be found by using the vertex formula for parabolas.

The function in question is f(x)=-[tex]x^2[/tex]+8x-20. This is a quadratic function, and since the coefficient of [tex]x^2[/tex] is negative, the graph of the function will be a downward-opening parabola. To find the maximum value of this function, we need to determine the vertex of the parabola.

The vertex of a parabola in the form of f(x)=[tex]ax^2[/tex]+bx+c is given by the formula h=-b/(2a). Plugging in our coefficients a=-1 and b=8, we find the x-coordinate of the vertex to be h=-8/(2(-1))=4. To find the corresponding y-coordinate, which is the maximum value, we substitute x=4 into the original function [tex]ax^2[/tex]+bx+c:

f(4)=[tex]-4^2+8\times4-20[/tex]

f(4)=-16+32-20

f(4)=-4

Therefore, the maximum value of the function f(x)=-[tex]x^2+8x-20[/tex] is -4, which occurs at x=4.
