1. Lenas total pay if she sells 25 copy is $3050.
2. The copy sold is 34.
What is the Lenas total pay if she sells 25 copy's?From the information given, Lena is a software salesperson. Her base salary is $1800 and she makes $50 more for every copy of English is Fun she sells.
It should be noted that the total pay, P after selling c copies is given by:
P = 50c + 1800
c = number of copies
The pay for 25 copies will be:
P = 50c + 1800
P = 50(25) + 1800
P = 1250 + 1800
P = 3050
When lenas total pay is 3500 the copys did she sell will be:
50x + 1800 = 3500
Collect like terms
50x = 3500 - 1800
50x = 1700
Divide
x = 34
The copy is 34.

Three friends decide to rent an apartment and split the cost evenly. They each paid $640 towards the total move in cost of first and last month's rent and a security deposit. If rent is $650 per month, how much was the security deposit? a. $10 b. $207 c. $620 d. $1,270 Please select the best answer from the choices provided A B C D.
Total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.
What is monthly payment?The monthly payment is the amount which is required to pay each month to pay off the borrowed principal amount or the rent of a service charged monthly.
The rent of the apartment is $650 per month. The rent of the two months (first and last) is,
[tex]M=2\times650\\M=1300[/tex]
This rent is paid by three friends. Thus, the amount which is paid by an individual friend is,
[tex]P=\dfrac{1300}{3}\\P=433.33[/tex]
They each paid $640 towards the total move in cost of first and last month's rent and a security deposit. Therefore,
[tex]P=640-433P=206.67[/tex]
Thus, $206.67 is paid by each of them towards security deposits. The total amount of security deposit, deposited by 3 of them, is,
[tex]SD=206.67\times3\\SD=620.01[/tex]
Hence, total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.

The correct answer is: " [tex]j^(^-^4^)[/tex] "; or; write as: " [tex]j^{-4}[/tex] ".
_______
Step-by-step explanation:
Given: " [tex]\frac{j}{j^4* j}[/tex] " ; assuming: " [tex]j\neq 0[/tex] " ;
_______
We are asked to express the correct answer (i.e. simplying the expression in a specific manner): "as a single term, without a denominator."
_______
As such, we can cancel out the "j" in the numerator, to "1" ; and cancel out the "j" in the denominator; to "1" ; since: " j ÷ j = 1 " ;
→ And we can rewrite the expression as:
" [tex]\frac{1}{j^{4}* 1 }[/tex] " ;
= " [tex]\frac{1}{j^4}[/tex] " ;
_______
Now, note the following property of exponents:
_______
" [tex]x[/tex]⁽⁻ⁿ⁾ = [tex]\frac{1}{x^n}[/tex] " ; {" [tex]x\neq 0[/tex] "} ;
_______
Likewise:
" [tex]\frac{1}{j^4}[/tex] ⇔ " [tex]j^(^-^4^)[/tex] " ; which is the correct answer:
→ " [tex]\frac{1}{j^4} = j^{-4}[/tex] " .

Answer:
see below for slopes and lengths
scalene quadrilateral
Step-by-step explanation:
When calculations are repetitive, it is reasonable to let a spreadsheet do them.
FG: slope: -4/5, length: √41 ≈ 6.40
GH: slope: -5, length: √26 ≈ 5.10
HI: slope: -1, length: 3√2 ≈ 4.24
IF: slope: 4, length: √17 ≈ 4.12
All of the segments are different lengths, and none of them are parallel or perpendicular. The figure is a scalene quadrilateral.

find the circle and radius of circle at x^2 +y^2 +10x - 6y + 14=0
Answer:
see explanation
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
Given
x² + y² + 10x - 6y + 14 = 0 ( collect the x/ y terms together and subtract 14 from both sides )
x² + 10x + y² - 6y = - 14
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(5)x + 25 + y² + 2(- 3)y + 9 = - 14 + 25 + 9
(x + 5)² + (y - 3)² = 20 ← in standard form
with centre = (- 5, 3 ) and r = [tex]\sqrt{20}[/tex] = 2[tex]\sqrt{5}[/tex]
Which expression is equivalent to 8 (6n + 6)?
- 48 + 6
- 8(n + 5n + 6)
- 6(8n + 6)
- 6 (6n + 8)
Answer:
Second option
Step-by-step explanation:
Given the following question:
[tex]8(6n+6)[/tex]
To find the answer we have to simplify the following expression and then simplify the options in till we have a equivalent answer.
[tex]8(6n+6)[/tex]
[tex]8\times(6n+6)[/tex]
[tex]8\times6n=48n[/tex]
[tex]8\times6=48[/tex]
[tex]48n+48[/tex]
Now one of these options after being simplified will be equal 48n + 48.
[tex]48+6[/tex]
Already simplified
First option isn't equivalent to the given expression.
[tex]8(n+5n+6)[/tex]
[tex]n+5n=6n[/tex]
[tex]8\times(6n+6)[/tex]
[tex]8\times6n=48n[/tex]
[tex]6\times8=48[/tex]
[tex]48n+48[/tex]
Second option is equivalent to the given expression.
