From 86 books to 150 books. An increase of 64 books.

(150 - 86) / 86 = 64 / 86 = 0.744 * 100% = 74.40% or 74% increase

150 / 86 = 1.744 * 100% = 174.40%

86 is the basis. It is 100%

If the problem asks for the value of the percentage increase and the rate is given 74.4% of 86. Then 86 * 74.4% = 64. You just add 64 to 86 to get the new total of books which is 150.

Define four symbolic constants that represent integer 25 in decimal, binary, octal, and hexadecimal formats
stealth61 [152]

Answer:

1) Decimal    25= (25)_{10}

2) Binary    25= (11001)_2

3) Octal   25= (31)_8

4) Hexadecimal   25= (19)_{16}

Step-by-step explanation:

Given : Integer is 25                      

To find : Represent integer in decimal, binary, octal, and hexadecimal formats.

Solution :

1) Integer into decimal - To convert into decimal the base goes to 10.

So, 25= (25)_{10}

2) Integer into binary - To convert into binary the base goes to 2, it form in 0 and 1 and we divide integer by 2.

Divide 25 by 2 and note down the remainders.

2 | 25

2 | 12    R=1    ←

2 | 6     R=0   ↑

2 | 3      R=0  ↑

2 | 1  →   R=1   ↑

So,   25= (11001)_2

3) Integer into octal - To convert into octal the base goes to 8 and we divide integer by 8.

Divide 25 by 8 and note down the remainders.

8 | 25

  | 3 →   R=1    

So,   25= (31)_8

4) Integer into hexadecimal - To convert into hexadecimal the base goes to 16 and we divide integer by 16.

Divide 25 by 16 and note down the remainders.

16 | 25

   | 1 →   R=9    

So,   25= (19)_{16}

Which property is represented in the example?
dybincka [34]
This is the distributive property; you're taking the 10 and giving it, or distributing it, to the 4 and the 3. the best way to remember it on sight is just thinking about what "distributing" means.

Question 131 ptsIt takes a team of 8 workers 2 hours and 15 minutes to clean 12 apartments. Howmany apartments can the tearsclea
Amanda [17]
48\:apartments\:in\:9\:hours

1) In this problem, the first thing to do is to enlist the categories:

workers time to clean # apartments

8 2h15 12

8 9 x

2) Note that the number of cleaners is the same. So, we can pick the ratios that fall under the category <em>time </em>and <em>#apartments</em>

<em />

We need to convert that 2h 15 into decimal form before setting the ratios:

2h15\:2+\frac{15}{60}=2.25

3) Now, we can set the ratios and solve for x:

\begin{gathered} \frac{2.25}{9}=\frac{12}{x} \\ 2.25x=12\cdot9 \\ \frac{2.25x}{2.25}=\frac{108}{2.25} \\ x=48 \end{gathered}

Thus, the answer is 48
