The price of each comb is $0.5, and the total income from selling x plastic combs is y = x/2
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
The linear equation y = x/2 models the income, in dollars, from selling x plastic combs. Hence:
Price of each comb = (x/2) / x = 0.5
The price of each comb is $0.5, and the total income from selling x plastic combs is y = x/2

0.6222... is a recurring decimal at the digit '2'
let x = 0.62222....
multiply x by 10 ⇒ 10x = 6.2222.... [we multiply by 10 to leave the recurring digits after decimal point]
multiply x by 100 ⇒ 100x = 62.2222... [we multiply by 100 so that we can again leave the recurring digit after decimal point]
subtract 10x from 100x
100x - 10x = 62.2222... - 6.2222...
90x = 56
x = 56/90
x = 28/45

The surface area is
Step-by-step explanation:
Shape is triangular prism,
Base = b = 9
Height = h = 7
The length of each side of the triangular prism ,
s₁ = s₂ = s₃ = 9
Width of the entire prism
Width = W = 7
To Find:
The surface area = ?
Solution:
Total Surface Area of Prism is given by,
Where,
b = Base
h = Height
s₁ , s₂ , and s₃ = length of each side of the triangular prism
W = width of the prism
Substituting the values we get
Therefore,
The surface area is
Answer:
Step-by-step explanation:
Lets look at the first pick. There are 9 items that can be choosen, one that cannot. So the chance to not pick the one is 9/10.
All the other attempts are the same and have 9/10 chance. (as replacement happens)
Now these events are independent of eachother so the combined chance is
(9/10)^10
For the formula:
Number of items: n
One pick is: (n-1)/n
N pick together is [(n-1)/n]^n
Answer:
y = 4x+2
Step-by-step explanation:
slope intercept form is y = mx+b
so we need to solve for y
-4x+y =2
add 4x to each side
4x-4x+y =+4x+2
y = 4x+2
