Step-by-step explanation:
Solution,
Let the total number of books be x, then
Books in English language=4800
40% of x=4800
40/100×x=4800
40x/100=4800
40x=4800×100
40x=480000
x=480000/40
x=12000
So the total number of books in the library is 12000.

Tomás found the following prices when he was shopping for sports jerseys: $28, $36, $40, $30, and $28. What is the median price?
Answer:
$30
Step-by-step explanation:
To find the median, arrange numbers from smallest to largest
The # of data points in this scenario are 5, which is odd. If the # of data points is odd, the median is the data point in the center.
$28, $28, $30, $36, $40
if you wanted to find the median with an even # of data points, it's the average of the two middle data points.
The median price of the sport jerseys is : $30
Given the prices :
$28, $36, $40, $30, $28
To find the median price, we need to arrange the values in order :
Ordered prices = $28, $28, $30, $36, $40
The median formula = 1/2(n+1)th term
n = number of terms = 5
Hence,
Median price = 1/2(5 +1)th term
Median price = 1/2(6) = 3rd term
The 3rd term = $30.
Hence, the median price is $30

Two rules for creating a pattern are given below. Each rule begins with a number called the input and
creates a number called the output.
Rule 1: Increase the input by 4 to get the output.
Rule 2: Multiply input by 2. Then subtract 1 to get the output.
Which input and output table works for both rules?
Choose 1 answer:
Input
Output
5
9
Input
Output
10
14
Input
Output
8
15
Answer:
A
Step-by-step explanation:
Table A
input is 5 and output is 9
Using the 2 given rules
Increase the input by 4 to get output , then
5 + 4 = 9 ← correct output
Multiply input by 2 and subtract 1 to get output , then
2 × 5 - 1 = 10 - 1 = 9 ← correct output
Table A works for both rules

Answer:
a) y = [tex]\frac{1}{2} x[/tex]
b) y = [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
I. If y = 9 and x = 18
so x is double value of y or y * 2
y will be half of x value
that makes y = [tex]\frac{1}{2}[/tex] x
II. If x = 5, replace x with 5
y = [tex]\frac{1}{2}[/tex] (5)
y = [tex]\frac{5}{2}[/tex]
Answer:
(a).
[tex]{ \boxed{ \sf{y = \frac{1}{2}x }}}[/tex]
b).
[tex]{ \boxed { \sf{y = \frac{5}{2} }}}[/tex]
Step-by-step explanation:
explanation for (a):
[tex]{ \sf{y \: \alpha \: x}} \\ { \sf{y = kx}} [/tex]
when y is 9, x is 18
[tex]{ \sf{9 = (k \times 18)}} \\ { \sf{k = \frac{1}{2} }}[/tex]
therefore equation is:
[tex]{ \sf{y = \frac{1}{2}x }}[/tex]
explanation for (b):
when x is 5:
[tex]{ \sf{y = \frac{1}{2}x }} \\ \\ { \sf{y = \frac{1}{2} \times 5}} \\ \\ { \sf{y = \frac{5}{2} }}[/tex]

|6a-5|=4a
the solutions are a= and a=
Answer:
a = 2.5, a = 0.5
Step-by-step explanation:
6a - 5 = 4a, and 6a - 5 = -4a
6a -5 = 4a
Subtract 6a from both sides
-5 = -2a
a = 2.5
6a - 5 = -4a
Subtract 6a from both sides
-5 = -10a
a = 0.5

-Chetan K
Answer:
a=1/2 and a=5/2
Step-by-step explanation:
6a-5=4a:
Subtract 4a from both sides, ending up with 2a-5=0
Add 5 to both sides, ending up with 2a=5
Divide both sides by 2, ending up with a=5/2
6a-5=-4a
Add 4a to both sides ending up with 10a-5=0
Add 5 to both sides ending up with 10a=5
Divide both sides by 10 ending up with a=1/2
In conclusion, there are two possible solutions to the equation; 1/2 and 5/2

Suppose y varies directly as x, and y = 9 when x = 36. Find y when x= 100.
Answer:
25
Step-by-step explanation:
let x = 36
y = 9
x2 = 100
y2 = y2
y : x :: y2 : x2
We know,
Product of means = Product of extremes
That is,
y(x2) = x(y2)
Substituting the values,
9(100) = 36(y2)
=> 36(y2) = 900
=> y2 = 900/36
=> y2 = 25
so when x = 100, y =25
At a small private college 9 / 20 of the students are female if there are 2160 female students how many male students
Answer:
4800
Step-by-step explanation:
x is the number of total students
x * 9/20 = number of female students
x * 9/20 = 2160
Multiply each side by 20/9
x * 9/20 * 20/9 = 2160 * 20/9
x =4800
