A store owner orders 25 calculators that cost $41 each. The store owner can sell each calculator for $50. The store owner sold 22 calculators to customers. He had to return 3 calculators that were never sold and pay a $5 charge for each returned calculator (although the initial cost is refunded). What is the storeowner's profit?
Answer:
$183
Step-by-step explanation:
He buys 25 calculators for $41 each meaning he spends $1025 in total. He was able to sell 22 calculators for $50 which amounts to $1,100. He then returns and is refunded for the original price of the 3 calculators meaning he gets $123 dollars back but he also has to pay $5 for each calculator he returned which takes away $15 from his profit. $123-$15= $108. ($1,100+$108)-$1025=$183.

Answer:
D. x = 7 and m∠LMN = 120°Step-by-step explanation:
Since MO bisect angle LMN, the angles formed are congruent:
∠LMO≅∠NMOSubstitute values and solve for x:
13x - 31 = x + 5313x - x = 53 + 3112x = 84x = 7Find the value of ∠LMN:
m∠LMN = 2*m∠LMOm∠LMN = 2(13*7 - 31) = 120°Correct option is D
Here,
MO is bisect of the [tex]\angle{LMN}[/tex],
SO,
[tex]\angle{LMO}[/tex]=~[tex]\angle{NMO}[/tex]
According to the question,
[tex]\bold{ 13x-31=x+53 }[/tex]
[tex]\bold{ 13x-x=53+31 }[/tex]
[tex]\bold{12x=84 }[/tex]
[tex]\bold{x=\dfrac{84}{12} }[/tex]
[tex]\bold{x=7 }[/tex]
Now we find the value of [tex]\angle{LMN }[/tex]
so,
[tex]\angle{LMO}=2×\angle{NMO }[/tex]
[tex]\bold{ 2×(13×7-37) }[/tex]
[tex]\bold{2×(91-31) }[/tex]

Question
If f(x) = x^2 + 7x and g(x) = 3x - 1, what is f(g(x))?
O 9x2 + x + 1
9x2 + 15x - 6
9x2 + 21x-6
9x2 - 27x
Help please
Answer:
9x^2 + 15x -6
Step-by-step explanation:
Your problem → If f(x) = x^2 + 7x and g(x) = 3x - 1, find f(g(x))?
f(x)=x2+7x,g(x)=3x-1,fog(x)=?
g(x)=3x-1,f(x)=x2+7x
fog(x)=f(g(x))
=f(3x-1)
=(3x-1)2+7⋅(3x-1)
=(3x-1)2+21x-7
=(9x2-6x+1)+21x-7
=9x2+15x-6
fog(x)=9x2+15x-6
Write in index form

A survey found that 6 out of 8 students own a pet. If there are 320 students in a school, what is a reasonable prediction for the number of students who own a pet?
Answer:
Reasonable prediction = 240 students
Step-by-step explanation:
Given that:
6 out of every 8 students own a pet.
Ratio = 6 : 8
Number of students surveyed = 320
Predicted number of students who own pets = x
Ratio = x : 320
As the relationship is proportional;
6 : 8 :: x : 320
Product of mean = Product of extreme
8x = 320 * 6
8x = 1920
Dividing both sides by 8
[tex]\frac{8x}{8}=\frac{1920}{8}\\x=240[/tex]
Hence,
Reasonable prediction = 240 students
Decide if the statement is true or false.
7 is a solution of - 4x = -28.
True,
-4x=-28
Divide by -4 on both sides and since the negatives cancel eachother, you're left with x=7
