In the 2017 fiscal year, the state of Alaska received $8.2 billion In revenues and had $7.2 billion in expenditures. What percen

konstantin123 [22]

To figure this out you can do 7.2/8.2, because you are trying to figure out how much of the total was used, and percentages would not be more than 100%. Doing this you would get ~.878. To convert this to a percent, you would just multiply it by 100, which would give you 87.8%. The question states to round to the nearest whole percent, leaving you with 88%. This means that 88% of the revenue was spent.

Hope that helped, don't be shy to comment on this if you have any questions about my explanation :)

What is the volume of a cylinder with a radius of 7 feet and a height of 12 feet? Use 3.14 for pi. Round your answer to the near

mylen [45]

Given :-

Radius of cylinder is 7ft.
Height is 12ft .

To Find :-

The volume of the cylinder .

Solution :-

As we know that the volume of the cylinder is ,

$\longrightarrow$ Volume = πr²h

On substituting the respective values ,

$\longrightarrow$ Volume = 3.14 * (7ft)²*12ft

$\longrightarrow$ Volume = 3.14*49ft²*12ft

$\longrightarrow$ Volume = 1846.32 ft.³

Hence the required answer is 1846.32 ft³.

A country has two political parties, the Demonstrators and the Repudiators. Suppose that the national senate consists of 100 mem

IRISSAK [1]

Answer:

(a) 4.148 x 10^(12) ways

(b) 5,827,360 ways

Step-by-step explanation:

Number of Demonstrators (D) = 44

Number of Repudiators (R) = 56

(a)

5 senate members must be Repudiators and 5 must be demonstrators, assuming that the order at which they are selected is irrelevant:

$N= C^{D}_{5} * C^{R}_{5}\\N=\frac{56!}{5!(56-5)!} *\frac{44!}{5!(44-5)!} \\N=3,819,816*1,086,008\\N=4.148 *10^{12}$

(b)

Since there are two different positions, (speaker and vice speaker), order is important in this situation, and the total number of ways to select two senators from each party is:

$N= P^{D}_{2} * P^{R}_{2}\\N=\frac{56!}{(56-2)!} *\frac{44!}{(44-2)!} \\N=3,080*1,892\\N=5,827,360$
