Answer:

The shop

Step-by-step explanation:

Given

Shop

[tex]Cost = E9[/tex]

[tex]Bag = 12.5kg[/tex]

Supermarket

[tex]Cost=E1.83[/tex]

[tex]Bag = 2.5kg[/tex]

Required

The better value

To do this, we simply calculate the unit price.

This is calculated as:

[tex]Unit = \frac{Price}{Bag}[/tex]

So, we have:

Shop

[tex]Unit = \frac{9}{12.5}[/tex]

[tex]Unit = 0.72[/tex]

Supermarket

[tex]Unit = \frac{1.83}{2.5}[/tex]

[tex]Unit = 0.732[/tex]

At the shop, the unit price is £0.72 per bag while at the supermarket, the unit price is £0.732

The best value is at the shop, because it is cheaper

i.e.

[tex]0.72 < 0.732[/tex]

What is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet? Be sure to convert so you are using like units.

Answers

Answer:

The height of the tank is 0.5 yards.

Step-by-step explanation:

To determine what is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet, knowing that the volume of a cylinder is equal to pi multiplied by the radius squared, multiplied by the height, the following calculation must be done:

1 foot = 0.3333 yards

R = Diameter / 2

R = 120/2 = 60

3.14 x 60 ^ 2 x H = 1,884

3.14 x 3,600 x H = 1,884

3.14 x 1,200 x H = 1,884

3.768 x H = 1.884

H = 1,884 / 3,768

H = 0.5

Therefore, the height of the tank is 0.5 yards.

A dress that is size x in France is equaivalent to size​ d(x) in the United​ States, where ​d(x)x32.
​(a). Find a function that will convert U.S. dress size to French dress size.
​(b) Use the inverse function to find the French size of a dress if it is U.S. size .

Answers

Answer:

[tex](a)\ d'(x) = x + 32[/tex] i.e. The inverse function

[tex](b)\ d'(10) = 42[/tex] i.e. The French size of a dress if it is U.S. size 10 is 42.

Step-by-step explanation:

Given

[tex]d(x) = x - 32[/tex]

Solving (a): The inverse function

[tex]d(x) = x - 32[/tex]

Replace d(x) with y

[tex]y = x - 32[/tex]

Swap y and x

[tex]x = y - 32[/tex]

Make y the subject

[tex]y = x + 32[/tex]

Replace y with d'(x)

[tex]d'(x) = x + 32[/tex]

Hence, the inverse function is: [tex]d'(x) = x + 32[/tex]

Solving (b): US size of 10

[tex]d'(x) = x + 32[/tex]

Substitute [tex]x =10[/tex]

[tex]d'(10) = 10 + 32[/tex]

[tex]d'(10) = 42[/tex]

What is the median

Answers

The median is 72 because you would have to least your number from least to greatest and what number is you middle number that is your median

Answer:

72 or 75

Step-by-step explanation:

If we are going in order then the median would be 72.

If we are going by what you posted, then it would be 75.

You were asking about the mean, so I though I would just add it in here.

So basically, the mean is just where you add up all the numbers, and then divide them by how many numbers you have.

For your problem, this is 39+87+72+88+75+87+15+53+53. This equals 569.

Now, lets count how many numbers we added: 1...2...3...4...5...6...7...8...9.

Ok, so lets divide the 569 by 9. This should get you 63.222...

That is your mean.

After completing 60% of the trip, they stopped at a gas station. They had traveled 216 miles. How many miles is the entire trip?

Answers

Answer:

Total distance of entire trip in miles = 360 miles

Step-by-step explanation:

Given:

Percent trip completing = 60%

Total distance cover in 60% trip = 216 miles

Find:

Total distance of entire trip in miles

Computation:

Total distance of entire trip in miles = Total distance cover in 60% trip[100%/Percent trip completing]

Total distance of entire trip in miles = 216[100%/60%]

Total distance of entire trip in miles = 21,600/60

Total distance of entire trip in miles = 360 miles
