Final answer:
The approximate difference between the average distances from the Sun to Jupiter and from the Sun to Neptune is approximately [tex]-3.71 * 10^9 km.[/tex]
Explanation:
The approximate difference between the average distances from the Sun to Jupiter and from the Sun to Neptune can be found by subtracting the average distance to Neptune from the average distance to Jupiter.
Average distance to Jupiter: 7.8 × 108 km
Average distance to Neptune: 4.51 × 109 km
Subtract the average distance to Neptune from the average distance to Jupiter:
[tex]= 7.8 * 10^8 km - 4.51 * 10^9 km[/tex]
= [tex]-3.71 * 10^9[/tex]
The approximate difference between the average distances is [tex]-3.71 * 10^9 km.[/tex]

A cylindrical shaped vase has the radius of 3cm and a height of 18cm. how much water is needed to fill the vase 3/4 of the way?
Answer:
Step-by-step explanation:
To fill the entire vase:
pi(3)^2(18)= 508.9 cubic centimeters
To fill vase 3/4 of the way:
3/4= .75
So then you take what it takes to fill the vase (508.9) and multiply that by .75 which equals 381.70 cubic centimeters.
3/4 of the volume of water needed to fill the vase is 162π cm^3.
To find how much water is needed to fill the vase 3/4 of the way, we first need to calculate the volume of the vase and then determine 3/4 of that volume.
The formula to calculate the volume of a cylinder is:
[tex]Volume = \pi * radius^2 * height[/tex]
Given:
Radius (r) = 3 cm
Height (h) = 18 cm
Volume of the entire vase:
[tex]Volume = \pi * (3 cm)^2 * 18 cm\\Volume = \pi* 9 cm^2 * 18 cm\\Volume = 162\pi cm^3[/tex]
Now, to find 3/4 of the volume, multiply the total volume by 3/4:
[tex]3/4 * 162\pi cm^3 = 3 * 54\pi cm^3 = 162\pi cm^3[/tex]
So, 3/4 of the volume of water needed to fill the vase is 162π cm^3.

If an article costs a store $7.45 and if it sells the article for $9.95, what percentage (to the nearest tenth) markup is it using?
subtract to find the difference:
9.95 - 7.45 = 2.50
divide 2.50 by cost price to get mark up percentage
2.50 / 7.45= 0.3355
= 33.6 percent to the nearest tenth
Answer:
Markup Percentage is 33.56 %
Step-by-step explanation:
Given: Cost of an article = $ 7.45
Selling price of the article = $ 9.95.
To find: Markup percentage or profit percentage
Clearly Selling price is greater we have profit in this case.
Profit amount = 9.95 - 7.45 = $ 2.50
Profit percentage = [tex]\frac{2.50}{7.45}\times100=33.5570469799=33.56[/tex] %
Therefore, Markup Percentage is 33.56 %

What is the surplus for the five companies?Producer Surplus is the difference between the price at which a producer is willing to spend and the price which he is getting from the market for his product.
The minimum price at which a producer is willing to spend is the Marginal Cost of producing that product.Therefore, Producer surplus is Market Price- Marginal CostProducer Marginal Cost Market Price Producer Surpus Company 1 1,000,000 1,470,000 (1,470,000-1,000,000)=470,000

Final answer:
The surplus for Companies 1, 2, and 3 is $470,000, $220,000, and $170,000 respectively, as their marginal costs are less than the market price of $1,470,000. Companies 4 and 5 do not have a surplus since their marginal costs are above the market price. The total surplus is $860,000.
Explanation:
The surplus for the five construction companies based on their marginal costs and the market price of an overseas factory can be calculated as the difference between the market price and the marginal cost for each company. Only the companies that have a marginal cost lower than the market price will experience a surplus. Given that the market price is $1,470,000:
Company 1 has a surplus of $470,000 ($1,470,000 - $1,000,000).
Company 2 has a surplus of $220,000 ($1,470,000 - $1,250,000).
Company 3 has a surplus of $170,000 ($1,470,000 - $1,300,000).
Companies 4 and 5 do not have a surplus because their marginal costs are higher than the market price. The total surplus for the three companies with a surplus is $860,000 ($470,000 + $220,000 + $170,000).

PLEASE HELP ASAP DUE IN A DAY What is the unit rate for 768.57 m 41.1 h? Enter your answer, as a decimal, in the box.
The unit rate for 768.57 meters in 41.1 hours is approximately 18.68 meters per hour. This calculation is derived by dividing the distance by the time to find the rate of movement.
To find the unit rate, divide the distance by the time:
[tex]\[ \text{Unit rate} = \frac{\text{Distance}}{\text{Time}} \][/tex]
[tex]\[ \text{Unit rate} = \frac{768.57 \, \text{m}}{41.1 \, \text{h}} \][/tex]
[tex]\[ \text{Unit rate} \approx \frac{768.57}{41.1} \, \text{m/h} \][/tex]
[tex]\[ \text{Unit rate} \approx 18.68 \, \text{m/h} \][/tex]
So, the unit rate is approximately 18.68 meters per hour.
The sum of two positive numbers is 12. what two numbers will maximize the product g
Given two numbers x and y such that:
x + y = 12 ... (1)
from equation (1)
y = 12 - x
Using this value of y, we represent xy as
xy = f(x)= x(12 - x)
f(x) = 12x - x^2
Differentiating the above function:
f'(x) = 12 - 2x
Maximum value of f(x) occurs at point for which f'(x) = 0.
Equating f'(x) to 0 we get:
12 - 2x = 0
2x = 12
> x = 12/2 = 6
Substituting this value of x in equation (2):
y = 12 - 6 = 6
Therefore, value of xy is maximum when:
x = 6 and y = 6
The maximum value of xy = 6*6 = 36
The two numbers that sum up to 12 and maximize the product are 6 and 6.
Let's denote the two numbers by x and y. We know that x + y = 12, and we want to maximize the product P = xy.
First, express y in terms of x,
y = 12 - x
P = x(12 - x)
= 12x - x²
To find the maximum value of P, we can take the derivative of P with respect to x and set it to zero,
dP/dx = 12 - 2x
Set dP/dx to 0: 12 - 2x = 0
x = 6
Since x + y = 12, if x = 6, then y = 12 - 6 = 6.
The two numbers are 6 and 6.
This combination will maximize the product, which is 6 * 6 = 36.
In conclusion, the two numbers that add up to 12 and maximize their product are both 6.
Which equation can be used to find the answer? A playground with four sides has a perimeter of 52 ft. Three of the sides have lengths of 9 ft, 16 ft, and 19 ft. What is the length of the fourth side? A. s – 9 + 16 + 19 = 52 s =26 26 ft B. s + 9 + 16 + 19 = 52 s = 8 8 ft C. s – 52 = 9 + 16 – 19 s = 58 58 ft D. s – 9 – 16 – 19 = 52 s = 96 96 ft
Option B)s + 9 + 16 + 19 = 52. Solving this gives the fourth side as 8 ft.
To find the length of the fourth side, you need to know the equation that correctly represents the given information. The perimeter of the playground is the sum of all four sides. Therefore, the correct equation to find the fourth side (s) is:
B. s + 9 + 16 + 19 = 52
9 + 16 + 19 = 44.
s + 44 = 52.
s = 52 - 44.
s = 8.
Therefore, the length of the fourth side is 8 ft.
So, the correct option is B. s + 9 + 16 + 19 = 52.

A rectangular garden must have an area of 64 square feet. find the minimum perimeter of the garden.
A rectangular garden must have an area of 64 square feet then the minimum perimeter of the garden is 32 feet and this can be determined by using the formula of the perimeter of a rectangle.
Given :
A rectangular garden must have an area of 64 square feet.
The area of a rectangle is given by:
[tex]\rm A =l\times w[/tex]
where 'l' is the length of the rectangle and 'w' is the width of the rectangle.
Given that area of the rectangular garden is 64 square feet that is:

Two planes which are 3540 miles apart fly toward each other. Their speeds differ by 35 mph. If they pass each other in 4 hours, what is the speed of each?
Final answer:
The speed of the slower plane is 425 mph, and the speed of the faster plane is 460 mph, determined by using the concept of relative speed and algebra to solve the given equation.
Explanation:
To solve the problem of two planes flying towards each other, we need to use the concept of relative speed. We know that the two planes are 3540 miles apart and that they pass each other after 4 hours. The speeds of the planes differ by 35 mph. The relative speed of the two planes combined is the distance divided by the time, so we calculate it as follows:
Relative Speed = Total Distance / Time = 3540 miles / 4 hours = 885 mph
So, if we denote the speed of the slower plane as S mph, the speed of the faster plane will be S + 35 mph. Since their combined speed is the relative speed, we can set up the following equation:
S + (S + 35) = 885
From this equation, we need to find the value of S which represents the speed of the slower plane. We can then add 35 to S to find the speed of the faster plane. Here's how it's done step by step:
Combine like terms: 2S + 35 = 885Subtract 35 from both sides: 2S = 850Divide by 2 to solve for S: S = 425 mphAdd 35 to S to find the speed of the faster plane: 425 + 35 = 460 mphTherefore, the speed of the slower plane is 425 mph and the speed of the faster plane is 460 mph.
