sample size of this?

Answer:

Let x represent the edge dimension of the square base in feet. Then the area of the base or lid is x², and the height of the box is 5/x². Total cost is then ...

... cost = cost of lid + 4×(cost of one side) + cost of bottom

... cost = 0.2x² + 4×(0.2x(5/x²)) + 0.5x²

... cost = 0.7x² + 4/x

We can differentiate this with respect to x and set that derivative to zero. This will give us the x-value at which the cost is a minimum.

... d(cost)/dx = 1.4x -4/x² = 0

... x³ = 4/1.4

... x = ∛(20/7) ≈ 1.419

Then the height of the box is

... height = 5/x² ≈ 5/2.01351 ≈ 2.483

The box is 1.491 ft square and 2.483 ft high.

______

The average cost of the top and bottom is (0.2 +0.5)/2 = 0.35 per square foot. The overall cost will be minimized when the average cost of each face is the same. That is, the areas of the lateral faces will be equal and must be 0.35/0.2 = 1.75 times the area of the top or bottom to make the average cost of a lateral face equal to that of the top or bottom. Hence, the base will be square, and the box will be 1.75 times as high as it is wide or deep. The base edge dimension is then ∛(5/1.75) ≈ 1.419 ft.

Answer:

By using the 90 degree clockwise rotation formula, we are able to determine that the answer is (7, 6)

Step-by-step explanation:

The formula for 90 degree clockwise rotation is

(x,y)--->(y,-x)

The reason why our -6 turns into a positive is because the negative was replacing that negative therefore making it positive.

Hope this helps!

I'll leave the rest of the formulas I have in my notes for you!

180 degree rotations

(x,y)--->(-x,-y)

90 degree counterclockwise

(x,y)--->(-y,x)

270 degree rotation

(x,y)--->(y,-x)

Let me know if I am wrong

Answer:

Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be

The general formula is:

ρ

=

m

V

where

ρ

is density in

g/mL

if mass

m

is in

g

and volume

V

is in

mL

.

So to get the mass...

m

=

ρ

V

Or to get the volume...

V

=

m

ρ

When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.

Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.

These days, you should be able to search for the density of any common object.

When you have the density and volume but not the mass, then just make up a mass.

You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.

Answer:

x-13

Step-by-step explanation:

why you may ask?

subtracted=being taken away from

13 is *being taken away from* x

so if using numbers, 13 is being taken away from 20

or 13 is being subtracted from 20 would be 7, so x-13 would be your expression

Important info:

- Sophia has $6 to spend on lunch

- Concession stands sell sodas for $0.75

- All of their food items for $1.50

- Pretend she buys one drink

- Find the maximum amount of food she can buy now.

Process:

Subtract 600 and 75 since $6 = 600 cents

600 - 75 = 525

So Sophia has $5 and 25 cents left

Each food item is worth $1.50 which is 150 cents and she currently has $5.25 which is 525 cents

So divided 525 and 150

525 / 150 = 3.5

Unfortunately she can't buy half of a food item so the answer would be 3

Final Answer:

3, Sophia can buy 3 food items after buying 1 drink

Answer:

Eve will pay $97 if she buys it during the sale.

Step-by-step explanation:

price during sale = original price - (original price * discount percentage)

disc. % = 75%

75% = 0.75

pr. = 388 - (388 * 0.75)

pr. = $97

Answer:

97$

Answer:

a = 2

Step-by-step explanation:

4 (2a + 3) = 28

4 * 2

= 8

4 * 3

= 12

8a + 12 = 28

28 - 12

= 16

8a = 16

16 / 8

= 2

a = 2

Answer: Scalene

Step-by-step explanation:

None of the angles equals the other so no isosceles or equilateral and a right triangle had a right angle and all right angles equal 90 degrees.

Answer:

200 → 400 → 800 → 1600 → 3200

Step-by-step explanation:

starting at 200 and multiplying by 2 until you have 5 numbers.

Answer:200,400,800,1600,3200

Step-by-step explanation:

are there any answer choices??

Answer:

B

Step-by-step explanation:

-the base angles are 34, so the total value of both base angles is 68

-an isosceles triangle is equal to 180

-subtract 68 from 180 for the answer, so the equation is 68+x=180

Answer:it a

Step-by-step explanation:

the answer is c because the definition of multiplicative inverse is :

In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x−1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number.
