Using proportions, it is found that his total electricity cost for the fans during one year is given by:
b. $3.84
What is a proportion?A proportion is a fraction of a total amount.
In this problem, for 3 months, he uses 4 portable fans, and each fan is on for about 96 hours per month, hence the total number of hours he uses it is:
4 x 96 = 384 hours.
The cost is one one cent per hour, hence:
$0.01 x 384 = $3.84.
Which means that the total cost is of $3.84, and option b is correct.

An article was sold for ₹250 with a profit of 5%. What was its cost price?
Answer:
Selling Price 250
Profit =5%
We are given to find the cost price of articles .
First we find the profit
► Profit = 250/100 × 5
► Profit = 2.5×5
► Profit = 12.5
Cost Price = Selling Price - Profit► Cost Price = 250-12.5
► Cost Price = 237.5
So, the cost price of the article is 237.5
Selling price of the article.
Profit percentage %.
To do:
We have to find the cost price.
Solution:
Let the cost price of the article be .
Profitpercent = SP-CP/CP × 100
5 = 250-x/x x 100
5x = (250-x) 100
x = (250-20) 20
x = 250 (20) - 20x
x + 20x = 5000
21x = 5000
x = 5000/21
x = 238
Therefore; cost price of the article is Rs 238

Your total after 4 games of bowling was $28
and after 6 games it was $40. What was the
initial cost to rent the shoes before bowling
any games?
Answer:
$4
Step-by-step explanation:
Let x be the cost of a game of bowling and y be the cost to rent the shoes before the game then...
4x+y=28
6x+y=40
We can solve this system using elimination. In this scenario, we can eliminate y by subtracting the two equations...
-2x=-12
Divide both sides by -2
x=6
Plug 6 back in for x to solve for y
4(6)+y=28
24+y=28
Subtract 24 from both sides
y=4
It costs $4 to rent the shoes before bowling

The simplified form of the algebraic expression [tex]\frac{x+2}{x^{2} +5x+6} / \frac{3x+1}{x^{2} -9}\\[/tex] is [tex]\frac{x-3}{3x + 1}[/tex].
What is simplifying an algebraic expression?Simplification of an algebraic expression can be defined as the process of writing an expression in the most efficient and compact form without affecting the value of the original expression.
[tex]= \frac{x+2}{x^{2} +5x+6} / \frac{3x+1}{x^{2} -9}\\ \\ = \frac{x+2}{x^{2} +5x+6} * \frac{x^{2} -9}{3x+1}[/tex]
Solving in parts,
[tex]=x^{2} +5x + 6\\\\= x^{2} + 2x + 3x + 6\\\\=x(x+2) + 3(x+2)\\\\=(x+2)(x+3)[/tex]
[tex]= x^{2} -9\\\\= x^{2} - 3^{2}\\ \\=(x - 3)(x + 3)[/tex]
[tex]= \frac{x+2}{x^{2} +5x+6} * \frac{x^{2} -9}{3x+1}\\\\= \frac{x+2}{(x+2)(x+3)} * \frac{(x+3)(x-3)}{3x+1}\\ \\=\frac{x-3}{3x + 1}[/tex]

f(x)=3(2)^x ; x= -1 evaluate for X
Hey there!
f(x) = 3(2)^x
f(x) = 3(2)^-1
y = 3(2)^-1
y = 3 * 2^-1
y = 3 * 1/2
y = 3/1 * 1/2
y = 3(1) / 1(2)
y = 3/2
y ≈ 1 1/2
Thus, your answer is: y = 3/2 or y = 1 1/2
