The amount of water inside each of these things is proportional to the volume of the tank the tropical fish tank has a volume of
k0ka [10]

Answer:

1920 gallons of water

Step-by-step explanation:

From the question; the amount of water is proportional to volume of the tank

i.e amount of water = volume of the tank

in a tropical fish;

3000 gallons of water = 12.5 m³     ----- Equation (1)

However, in the  measurement of  shark tank, we have

length = 20cm = 0.2 meters

width = 4 meters

Height = 10 meters

How many gallons of water can the shark tank hold?

From the measurement of  shark tank, we can calculate the volume;

The volume of the tank = Length × width × height

Volume of the tank = 0.2 × 4 × 10 = 8 m³

since, the amount of water is proportional to volume of the tank

y ( Gallons of water ) = 8 m³    -------- Equation (2)

Equating equation 1 and 2; we have:

3000 gallons of water = 12.5 m³  

y ( Gallons of water ) = 8 m³    

y ( Gallons of water ) ×  12.5 m³  = 3000 gallons of water × 8 m³  

y ( Gallons of water )  = \frac{3000 gallons of water * 8 m^3  }{12.5m^3}

y ( Gallons of water )  = \frac{24000}{12.5}

y ( Gallons of water )  = 1920 gallons of water

Thus, the shark tank can hold 1920 gallons of water

an economic research commission claimed that among the 500 stores there are 308 dealing with european companies, 266 dealing wit
Rudiy27

Step-by-step explanation:

Let S be the set of all the stores in the sample, A be the set of stores dealing with Asian companies and E but the set of stores dealing with European companies

i. The set of stores that deal with European or Asian companies is A ∪ E. The inclusion-exclusion principle states that |A ∪ E| = |A| + |E| - |A ∩ E| = 266 + 308 - 103 = 471. So P(A ∪ E) = 471/500 = 0.942

ii. E' = S - E. |S-E| = 500 - 308 = 192. So P(E') = 192/500 = 0.384

iii. |A - E| = |A| - |A ∩ E| = 266 - 103 = 163. So P(A - E) = 163/500 = 0.326

iv. Stores that do not deal with only one type of company, must deal with both Asian and European companies. We are given that |A ∩ E| = 103. So P(A ∩ E) = 103/500 = 0.206

Easy, right?

The national debt in 2013 was $16,755,133,009,522. What is the smallest power of 10 that will exceed this number.​
Artemon [7]

Answer:

10^{14}

Step-by-step explanation:

In scientific notation, the national debt in 2013 was approximately

1.67 \times 10^{13}

You can see this by taking the decimal point between the 1 and 6 and moving it 13 places to the right.

The smallest power of 10 that will be larger than this number is  10^{14}.

Answer:

The answer to your question is     2C - 9 ≤ - 22

Step-by-step explanation:

I will write the answer step by step

1.- twice a number; let C be the number

                                 2C

2.- The difference of twice a number and 9

                                 2x - 9

3.- At most    " ≤ " Use this symbol and not "<" to indicate that number -22 is consider by the inequality.

4.- The inequality is

                                 2C - 9 ≤ - 22
