A cardboard box has a volume that is 6,336 cubic inches. A company creates a new design with the same proportions, but instead the dimensions are One-fourth the dimensions. Explain how you can find the volume of the new design without knowing the dimensions.
Answers
Answer:
Cube the scale factor 0.25. Then multiply the volume of the box by 0.015625.
Answer:
Since the dimensions have a proportional relationship, the new volume can be calculated using the original volume and the scale factor. The new volume will be the cube of the change, which is 1

The answer that is worth the Brainliest has all the answers to my questions, and is correct.
Answers
Answer:
1. J=20, f= 28, H=42
2. 240 + 241 + 242 = 723
Step-by-step explanation:
J= 30- 12= 18+2= 20
F= 30-2=28
H=30+12=42
2.
240 + 241 + 242 = 723
Fay has $32 to begin with
Henry has $18 to begin with
They all end with the same amount which must be 30.
40-12=28.- Jane 18+12=30- Henry
32-2=30-Fay. 28+2=30

Ellena knows that 1/5 written as a decimal is 0.2. How can Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5?
Answers
I hope this helped :)
The decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5
How to convert from decimal to fraction?For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.
WE are given that Ellena knows that 1/5 written as a decimal is 0.2.
Thus Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5
By multiplying 0.2 by 9 we can get the decimal equivalent of 9/5.
0.2 x 9 = 4.5
Hence, the decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5

On his way to the library , Jeff runs two blocks and then walks three more blocks.Sketch a graph to show the distance Jeff travels compared to time.
Answers
Answer:
Since I can't take a picture, I am going to explain how to draw it.
Step-by-step explanation:
When sketching the graph you must note if jeff is going up the y-axis and along the x-axis. In this case, run means he goes up every minute. So when jeff runs he is going up and 2 minutes have gone by. And when he walks he is going up 3 more but slower so it would double the time. Time would be on the x-axis and blocks would be labeled on the y-axis.

Consider the two functions below. Which one of these functions is linear? What is its equation? Enter any answers to two decimal places.
Answers
Answer:
Function A and the equation would be y = 1.6666666666~x + 0
Step-by-step explanation:
A linear function is a function that is a straight line with no change so function B does not fit that description. So than it has to be A
To find the equation you first what to find the slope of the line
ΔY/ΔX = 5/3 = 1.666666666666
Take the slope and multiply it by x to get y
Following are the solution to the given function:
Given:
Function A:
[tex]\bold{x} \ 3 \ 6 \ 9 \ 12 \ 15 \\\\\bold{y} \ 5 \ 10 \ 15 \ 20 \ 25[/tex]
To find:
Find the function=?
Solution:
Function A or equation would've been [tex]\bold{y = 1.6666666666 \sim x + 0}[/tex].The linear equation is a straight line with really no modification, hence function B doesn't suit its description. As a result, it has to be A.You must first calculate the slope of the line to solve this equation.[tex]\bold{\to \frac{\Delta Y}{ \Delta X} = 5/3 = 1.666666666666}[/tex]To get y, take the slope then multiply this by x.wich inequality is true?

Please help, I need help on this math question
Answers
Answer:
Probably C
Step-by-step explanation:
Repeating Decimal: a decimal where a number or a pattern of numbers repeats forever
For example, 0.2222... or 0.671671.... (The "..." means that it repeats like that forever)
A. 3/7= 0.142857142857142857... (6 repeating digits) This is a repeating decimal because the last six digits continue forever
B. 3/4=0.75. This number is not a repeating decimal because a repeating decimal goes on forever, while this only has two decimal places.
C. 1/9= 0.11111... This is a repeating decimal because it goes on forever and has a pattern (all are 1s)
D. 5/11=0.454545... This is also a repeating decimal because the last two digits repeat forever.
There is probably something wrong with the question (or your unit) because three of these numbers are, in fact, repeating decimals. If I were you, I would ask your teacher (it gets you respect from the teacher=more chance that they'll be lenient with you)
But if you really don't want to, I would go with "C" because it only has one repeating decimal place, and your curriculum probably says that a repeating decimal is only one digit.
Good Luck! :)
