In a stand there are 15 books. 5 of them are Mathematicsbooks.

8090 [49]

Answer: At least 4/14 = 28.5%

Step-by-step explanation:

Select the location of a math book at the far end. The probability that the book next to it is a math book:

4 remaining math books, out of the 14 remaining books

In the middle, there are two potential spots adjacent to each book, so it could be higher - that’s why I say “at least” 4/14

Drew made $18 per hour. Then he got a 10% raise. After cutbacks, he then had to reduce his hourly rate by 3%. What is his hourly

antiseptic1488 [7]

Answer:

19.206

Step-by-step explanation:

First you need to find out 10% of 18.

You can do that by 18/100 which is .18.

Then multiply that by 10 which is 1.8 (10% of 18)

His hourly rate decreased by 3% AFTER his raise so you would find 3% of 19.8 and not 18.

You do the same process and divide 19.8/100

Then multiply this by 3 and you can get 0.594

That is how much his raise decreased by so you would subtract it from 19.8

19.8 - 0.594 = 19.206 (Round if needed)

Hope this helps

Solve the system by substitution 6x+2y=26 x=6y+21

Savatey [412]

Substitute x = 6y + 21 into the first equation:-
6(6y+21) + 2y = 26
36y + 126 + 2y = 26
38y = -100
y = -2.63
x = 6(-2.63) + 21 = 5.22

answer (-2.63, 5.22) to nearest hundredth

Over the last three evenings, Martina received a total of 99 phone calls at the call center. The third evening, she received 4 t

Ket [755]

A = number of calls the first evening

b = = number of calls the second evening

c = number of calls the third evening

we know that she received a total of 99 calls, thus whatever "a", "b" and "c" are, we know that a + b + c = 99.

"The third evening, she received 4 times as many calls as the first evening"

c = 4a

"The second evening, she received 9 more calls than the first evening."

b = a + 9

 $\bf \begin{cases}
a+\underline{b}+\underline{c}=99\\
c=4a\\
b=a+9\\
----------\\
a+\underline{(a+9)}+\underline{(4a)}=99
\end{cases}
\\\\\\
a+a+9+4a=99\implies 6a=99-9\implies 6a=90\implies a=\cfrac{90}{6}$

and surely you know how much that is. Well, she got that many the first night.

how many the second night? well b = a + 9
what about the third night? well, c = 4a.
