Step-by-step explanation:
We have that:
The ratio of the edges is x.
The ratio of the surface areas is given by [tex]x^2[/tex]
The ratio of the volumes is given by [tex]x^3[/tex]
In this question, we have that:
[tex]x^2 = \frac{49}{81}[/tex]
So
[tex]x = \sqrt{\frac{49}{81}} = \frac{7}{9}[/tex]

Two publishers have offered Melanie Thompson a deal on her new
book Sugar-Free Culinary Classics. The first has offered to pay
her $82,000 up front and a $5.50 royalty for every book it
sells. The second has offered to pay $68,000 up front and a
$6.75 royalty for every book it sells. Over what range of book
sales will Melanie make more from the second publisher than she
will from the first?
Answer:
Step-by-step explanation:
68000+6.75b>82000+5.5b. subtract 5.5b from both sides
68000+1.25b>82000. subtract 68000 from both sides
1.25b>14000. divide both sides by 1.25
b>11200
So she must sell more than 11500 books to make more with second publisher.

The total cost C for a manufacturer during a given time period is a function of the number N of items produced during that period. To determine a formula for the total cost, we need to know the manufacturer's fixed costs (covering things such as plant maintenance and insurance), as well as the cost for each unit produced, which is called the variable cost. To find the total cost, we multiply the variable cost by the number of items produced during that period and then add the fixed costs.
a. Use a formula to express the total cost C of this manufacturer in a month as a function of the number of widgets produced in a month. Be sure to state the units you use.
b. Express using functional notation the total cost if there are 250 widgets produced in a month, and then calculate that value.
Answer:
(a) C = 9000 + 15N
(b) Cost of 250 widgets is $12750
Step-by-step explanation:
The question has missing details. See attachment for complete question
Solving (a): An expression for total cost.
The expression is generated using:
[tex]Total\ Cost = Fixed\ Cost + Variable\ Cost * Number\ of\ Items[/tex]
From the given parameters:
[tex]Fixed\ Cost = 9000[/tex]
[tex]Variable\ Cost = 15[/tex]
[tex]Number\ of\ Items = N[/tex]
So, the expression becomes:
[tex]C = 9000 + 15 * N[/tex]
[tex]C = 9000 + 15 N[/tex]
Solving (b): Cost of 250 widgets
In this case:
[tex]N =250[/tex]
Substitute 250 for N in [tex]C = 9000 + 15 N[/tex]
[tex]C = 9000 + 15 * 250[/tex]
[tex]C = 9000 + 3750[/tex]
[tex]C = 12750[/tex]

Approximately__ tons of LNG will be produced in may, and approximately 104,489 tons will be produced in___
Help plz :,)
Answer:
Step-by-step explanation:
For all Plato users
Approximately 94437.825 tons of LNG will be produced in May, and approximately 104,489 tons will be produced in October month.
Given that, the production of LNG by an energy company increases by 1.7% each month.
How to find the percentage of the number?Convert the problem to an equation using the percentage formula: P% * X = Y.
Production in April month=91,307+1.7% of 91,307
=91,307+1.7% ×91,307
=92,859.219 tons
Production in May month=92,859.219×(1+1.7%)
=94437.825 tons
Production in June month=94437.825×(1+1.7%)=96,043 tons
Production in July month=96,043×(1+1.7%)=97,676 tons
Production in August month=97,676×(1+1.7%)=99,336.49 tons
Production in September month=99,336.49×(1+1.7%)=1,01,025.21 tons
Production in October month=1,01,025.21×(1+1.7%)=1,04,489 tons
94437.825 tons of LNG will be produced in May, and 104,489 tons will be produced in October month.

If y varies inversely with x, and y = 48 when x = 6, find y when x = 18.
Answer:
y = 16
Step-by-step explanation:
Given that,
y varies inversely with x i.e.
[tex]y=\dfrac{k}{x}[/tex]
Where
k is a constant of proportionality
Put y = 48 and x = 6 in the above equation to find k.
So,
[tex]k=48\times 6\\\\k=288[/tex]
Now put k = 288 and x = 18 in the above equation to find y.
[tex]y=\dfrac{288}{18}\\\\y=16[/tex]
So, the value of y is equal to 16 when x = 18.

Jenna has a rectangular pig pen that measures 8m wide by 10m long. She wants to increase the area to 168 m^2 by increasing the length and width by the same amount. What would you enter into desmos to represent the equation?
A) x^2 + 18x – 88
B) x^2 + 10x + 80
C) (8x)(10x)-168
D) None of the above
Answer:
The answer is A
Step-by-step explanation:
I just took the test and it was the answer!
The equation for the increase in length and width of the rectangular pig pen is x² + 18x - 88 = 0.
The correct option is (A).
What is Surface Area?The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement.
As per the given data:
The dimensions for the pig pen Jenna has is given.
The area of the pig pen is to be increased to 168 m² by increasing the length and width by the same amount.
Length of the rectangular pig pen = 10 m
Width of the rectangular pig pen = 8 m
Now, let's say that the length and width of the pig pen is increased by x m.
length = 10 + x
width = 8 + x
The expression for the area of the pig pen will be:
Area = length × width
168 = [10 + x][8 + x]
168 = 80 + 10x + 8x + x²
x² + 18x - 88 = 0
The equation for the increase in length and width of the rectangular pig pen is x² + 18x - 88 = 0.
Hence, The equation for the increase in length and width of the rectangular pig pen is x² + 18x - 88 = 0.
