Considering the dimensions of the given rectangular prism and it's volume, the height of the chest is of 8 inches.
What is the volume of a rectangular prism?The volume of a rectangular prism of width w, length l and height h is given by the multiplication of these dimensions, as follows:
V = lwh
For this problem, the dimensions are given as follows:
w = 16, l = 4h, V = 4096.
Hence the height of the chest can be found as follows:
lwh = 4096
16 x 4h x h = 4096
h² = 4096/64
h² = 64
h = 8.
Hence, the height of the chest is of 8 inches.

11 identical pairs of Air Jordan cost $660.What is the cost of one pair?
Answer:
$60
Step-by-step explanation:
11 identical pairs of Air Jordan cost $660.
To find the cost of one pair, you have simply to divide the total amount paid by the total number of pairs.
Total amount paid = $660
Total number of pairs = 11
The cost of one pair [tex]=\$660 : 11=\$60[/tex]
To find the cost of one pair of Air Jordan sneakers from the total cost of 11 pairs, divide the total cost ($660) by the number of pairs (11), which equals $60 per pair.
Explanation:The question concerns determining the cost of one pair of Air Jordan sneakers given the total cost for 11 pairs. This is a basic division problem that falls under the category of arithmetic in mathematics. To find the cost of one pair, divide the total cost by the number of pairs. Here is how the calculation is done step-by-step:
Determine the total cost of all pairs together, which is given as $660.Count the number of identical pairs, which we know is 11 pairs.Divide the total cost by the number of pairs: $660 ÷ 11 pairs = $60 per pair.Therefore, the cost for one pair of Air Jordan sneakers is $60.

Which of the following points is a solution to a system of linear equations
y<3x+5
y>-2/3x-3
_
a.(3,14)
b.(3,9)
c.(3,-14)
d.(3,-9)
Final answer:
The point (3,9) is the solution to the system of linear equations because it satisfies both inequalities y < 3x + 5 and y > -2/3x - 3 when the values of x and y are substituted into them.
Explanation:
To determine which of the given points is a solution to the system of linear equations:
y < 3x + 5
y > -2/3x - 3
We substitute the x and y values of each option into the inequalities to find a match.
For point (3,14): Substitute x = 3 and y = 14 into the inequalities.
14 < 3(3) + 5, which simplifies to 14 < 14; this is false.14 > -2/3(3) - 3, which simplifies to 14 > -5; this is true.So, (3,14) does not satisfy both inequalities.For point (3,9): Substitute x = 3 and y = 9 into the inequalities.9 < 3(3) + 5, which simplifies to 9 < 14; this is true.9 > -2/3(3) - 3, which simplifies to 9 > -5; this is true.Therefore, (3,9) satisfies both inequalities and is the solution.Points (3,-14) and (3,-9) can be quickly dismissed as they give negative values for y, which won't satisfy the first inequality since it requires y to be less than a positive value.

Answer:
[tex]x= 28\°[/tex]
Step-by-step explanation:
We have labelled the given diagram and redrawn again in the attachment.
Also from the labelled diagram given below the given details are;
∠CPQ =[tex](5y-4)\°[/tex]
∠RQF =[tex]3y\°[/tex]
∠BRH =[tex](2x+13)\°[/tex]
∠CPQ = ∠PQF (Alternate Interior Angle)
∠PQF + ∠RQF =180° (Straight angle property)
Now Substituting the values we get;
[tex]5y-4+3y=180\\8y=180+4\\8y=184\\y=\frac{184}{8}=23\°[/tex]
∠RQF =[tex]3y\° = 3\times23 = 69\°[/tex]
∠RQF = ∠BRH (corresponding angles)
[tex]69=2x+13\\2x = 69 -13\\2x=56\\x = \frac{56}{2} = 23\°[/tex]
Hence x = 23°

Of the following equations below, which equation represents a direct variation between x and y?
Select one:
A. 2y = 3x −7
B. y −4 = x +6
C. y +3 = x +3
D. 4y +1 = 4x−1
Answer:
C. y +3 = x +3
Step-by-step explanation:
We need to find in below option x has direct variation with y.
We solve for each;
A. [tex]2y = 3x-7[/tex]
From above equation we can state that 2 times y is equal to 7 less than 3 times of x.
Hence it doesn't represent direct variation.
B. [tex]y-4 = x+6[/tex]
Solving above expression we get;
[tex]y-4 = x+6\\y = x+6+4\\y=x+10[/tex]
From above equation we can state that y is equal to 10 more than x.
Hence it doesn't represent direct variation.
C. [tex]y+3 = x+3[/tex]
Solving above expression we get;
[tex]y+3 = x+3\\y = x+3-3\\y=x[/tex]
From above equation we can state that y is equal to x.
Hence it represent direct variation.
D. [tex]4y+1 = 4x-1[/tex]
Solving above expression we get;
[tex]4y+1 = 4x-1\\4y = 4x-1-1\\4y=4x-2[/tex]
From above equation we can state that 4 times y is equal to 2 less than 4 times of x.
Hence it doesn't represent direct variation.
Hence the Answer which represent direct variation of x and y is,
C. [tex]y+3 = x+3[/tex]

Step-by-step explanation:
it is 6.09 pm the movie starts at 6:30 pm. while standing in the line for the movie, you count 146 people in front of you. nine people buy their tickets in 70 seconds. will you be able to buy your ticket before the movie starts?
Step-by-step explanation:
It is given that [tex]9[/tex] people bought tickets in [tex]70[/tex] seconds.
So,[tex]\frac{9}{70}[/tex] people can buy tickets in a second.
It is given that the current time is [tex]6:09pm[/tex] and movie starts at [tex]6:30pm[/tex].
So there is [tex]30-9=21minutes[/tex] until movie starts.
In [tex]21[/tex] minutes,the number of persons that can buy tickets are [tex]\frac{9}{70}\times 21\times 60=162[/tex].
So,[tex]162[/tex] people can buy tickets in [tex]21[/tex] minutes.
Since there are only [tex]146[/tex] people in front of you,you can buy a ticket.
You receive an 11 percent commission on all sales you make if your commission for the month is 512.50 dollars what was your total sales
Total sales were $4659.1
Step-by-step explanation:
Given,
Commission = 11%
Amount of commission = $512.50
Let,
total sales = x
Therefore,
11% of x = 512.50
[tex]\frac{11}{100}x=512.50\\0.11x=512.50[/tex]
Dividing both sides by 0.11
[tex]\frac{0.11x}{0.11}=\frac{512.50}{0.11}\\x= $4659.1[/tex]
Total sales were $4659.1

Answer:
5/8
Step-by-step explanation:
if I understand correctly the problem is

to solve for x we need to isolate it, the first step in doing so is getting rid of the 3/4
2*X-3/4+3/4=1/2+3/4
simplify
2*X=1 1/4
the next step is getting rid of the 2
(2*X)/2=(1 1/4)/2

Answer:
[tex]n = 3[/tex]
Step-by-step explanation:
Given:
The equation given is:
[tex]p^3q^2(p^4q^n\times \frac{r^3}{r^{-4}})=p^7q^5r^7[/tex]
We simplify the given equation using the following law of indices:
[tex]a^m\times a^n=a^{m+n}\\\frac{a^m}{a^n}=a^{m-n}[/tex]
Therefore,
[tex]p^{3+4}q^{n+2}\times r^{3-(-4)})=p^7q^5r^7\\p^7q^{n+2}r^7=p^7q^5r^7\\q^{n+2}=q^5[/tex]
Since the base on both the sides is same, therefore, their exponents must also be same. This gives,
[tex]n+2=5\\n=5-2\\n=3[/tex]
Therefore, the value of 'n' is 3.

if 16 candy bars cost $20,how much do 24 candy bars cost.?
To find the cost of 24 candy bars, calculate the cost per candy bar (found by dividing $20 by 16, equaling $1.25) and multiply it by 24. Therefore, 24 candy bars would cost $30.
Explanation:The subject of the question involves unit pricing, a common concept in mathematics. To find the cost of 24 candy bars, first identify the cost per candy bar, then multiply this unit price by the number of candy bars in question.
From the question, we know that 16 candy bars cost $20. So the unit price, or cost per candy bar, is $20 divided by 16, which equals $1.25.
Therefore, the cost of 24 candy bars would be $1.25 (the cost per candy bar) multiplied by 24 (the number of candy bars), which equals $30. Hence, 24 candy bars would cost $30.
