First of all, we can eliminate choices B and D because subtraction will not help us find the sister's age. 

Since <span>Abbie is 5 years older than twice her sister's age, we can multiply to figure out her sister's age. To form the equation, letter C would be your best choice.

Hope that helps. -UnicornFudge aka Nadia</span>

The weight of a box of cereal can vary by of an ounce and still be sold as a full box. Each box is supposed to contain 18 ounces
mezya [45]

Answer:

If a box is supposed to contain 18 ounces, and the acceptable error is 1 ounce, then the acceptable range is:

18 oz - 1oz = 17oz to 18oz + 1oz = 19oz

Then the acceptable range is (17oz, 19oz)

if the weight is smaller than 17 oz, the box is not acceptable.

If the weight is bigger than 19 oz, the box is not acceptable.

Then the graph of the boxes that can not be sold as full boxes is:

<---16---------17-------18--------19-------20----------->

where 17oz and 19oz are not included, because are acceptable weigths.

A rectangular tank that is 5324 ft cubed with a square base and open top is to be constructed of sheet steel of a given thicknes
marishachu [46]

Answer:

Side of 22 and height of 11

Step-by-step explanation:

Let s be the side of the square base and h be the height of the tank. Since the tank volume is restricted to 5324 ft cubed we have the following equation:

V = s^2h = 5324

h = 5324 / s^2

As the thickness is already defined, we can minimize the weight by minimizing the surface area of the tank

Base area with open top s^2

Side area 4sh

Total surface area A = s^2 + 4sh

We can substitute h = 5324 / s^2

A = s^2 + 4s\frac{5324}{s^2}

A = s^2 + 21296/s

To find the minimum of this function, we can take the first derivative, and set it to 0

A' = 2s - 21296/s^2 = 0

2s = 21296/s^2

s^3 = 10648

s = \sqrt[3]{10648} = 22

h = 5324 / s^2 = 5324 / 22^2 = 11

Which terms could be used as the first term of the expression below to create a polynomial written in standard form? Select five
kondaur [170]

Answer:

The last two terms of the expression are

  ----+8r^2s^4-3r^3s^3

Both the last terms has variable of degree equal to (2+4=6) and (3+3=6).So, the first term must have degree greater than 6.

Correct Options are

 1.\rightarrow 3r^4s^5\\\\2.\rightarrow -r^4s^6

On any given day, Juan will break even if he earns as much money as he spends. On day 5, he records the expression 16+ (-16). Do
sertanlavr [38]

Answer:

Yes. Juan will break even because 16 and -16 are a zero pair. -16 is the additive inverse of 16. So the sum will be 0.
