The expression represents the

.
Answer:
It represents the total amount that Erin is going to spend at the store.
Step-by-step explanation:
You purchase a stock at $100 per share. It drops 40% the next day; however, a week later, it increases in value by 40%. If you sell it, will you break even? Explain your answer.
Answer:
No
Step-by-step explanation:
You start off with $400 and it drops 40%. Then the price dropped all the way down to $240. If it goes up another 40% of 240, that'll be $336. So you lost around $64
In this exercise we have to use our knowledge of finance to analyze the given situation and identify if a break even occurs, so we have:
Yes, you will have a break even, as you lose 16 dollars per sale.
First we have to analyze what the break even is, this would be:
In commerce and trade, particularly cost accounting, the break-even point (BEP) exist the point at that cost or expense and profit exist equal: there happen no total amount of money lost or gain, and individual bear "crushed even". In the linear case the break-even point happen effective the established costs detached for one contribution room around something for one.Returning to the question, we have that:
[tex]100-40\%= 60\\60+40\%=84\\100-84=16[/tex]

A triangle has side lengths of (7n-2p)(7n−2p) centimeters, (2n+4q)(2n+4q) centimeters, and (q-5p)(q−5p) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
(7n-2p)(7n−2p) + (2n+4q)(2n+4q) + (q-5p)(q−5p) OR
53n² +29p² +17q² -14np +8nq -10pq
Step-by-step explanation:
The perimeter is found by adding all the side lengths.
P = (7n-2p)(7n−2p) + (2n+4q)(2n+4q) + (q-5p)(q−5p)
We know that (a+b)(a+b) = (a+b)², and (a-b)(a-b) = (a-b)²
P = (7n-2p)² + (2n+4q)² + (q-5p)²
We know that (a+b)² = a²+b²+2ab, and (a-b)² = a²+b²-2ab
P = 49n² + 4p² - 14np +4n² +16q² + 8nq +q²+25p² -10pq
Combine like terms
P = 53n² +29p² +17q² -14np +8nq -10pqBased on the data which table shows a constant of proportionality of 3 for the ratio of Amos and guitars?

which property is illustrated by the following ?
if a = b + 7 and b + 7 = 9, then a = 9
Step-by-step explanation:
Associative property
We know
a + (b + c) = (a + b) + c
a = b + 7
b + 7 = 9
Rearrange Eq. 2
9 = b + 7
a = b + 7
Hence,
Value of a is 9

The relationship between adult dog weight x in pounds and the daily recommended amount of dog food y in cups is proportional.
Write an equation for the relationship. How much dog food is recommended for a 25- pound adult dog?
please help me
no links or files
thank you !
Using proportional relations, it is found that:
The equation for the relationship is [tex]\frac{x}{60}[/tex].[tex]\frac{5}{12}[/tex] cups is recommended for a 25- pound adult dog.-------------------------------
The amount of cups of food y is proportional to the weight of a dog, which is of x pounds, and thus, the following equation models the situation:
[tex]y = cx[/tex]
In which c is the constant of proportionality.
-------------------------------
[tex]\frac{1}{6}[/tex] of a cup is needed to feed a dog of 10 lbs.This means that when [tex]x = 10, y = \frac{1}{6}[/tex]This is used to find c.[tex]y = cx[/tex]
[tex]\frac{1}{6} = 10c[/tex]
[tex]60c = 1[/tex]
[tex]c = \frac{1}{60}[/tex]
Thus, the equation for the relationship is:
[tex]y = \frac{x}{60}[/tex]
-------------------------------
The amount of cups needed for a 25-pound dog is y when x = 25, thus:
[tex]y = \frac{25}{60} = \frac{5}{12}[/tex]
[tex]\frac{5}{12}[/tex] cups is recommended for a 25- pound adult dog.

35: Problem Solving:You deposit $2000 in an account that earns simple interest at an annual rate of 4%.How long must you leave the money in the account to earn $500 in interest?
36: Problem Solving: A flight averages 460 miles per hour.The return flight averages 500 miles per hour due to a tailwind.The total flying time is 4.8 hours.How long is each flight?
Answer:
35 :
t = 6.25 years
(about 6 years 3 months)
Equation:
t = (1/r)(A/P - 1)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
t = (1/0.04)((2500/2000) - 1) = 6.25
t = 6.25 years
The time required to get a total amount, principal plus interest, of $2,500.00 from simple interest on a principal of $2,000.00 at an interest rate of 4% per year is 6.25 years (about 6 years 3 months).
36:
The two distances are the same (out and back), so set them equal.
That is done by having a (rate)(time) equal a (rate)(time).
One time is “x” and the other is “4.8-x.”
One rate is 460 and the other is 500.
460 x = 500 (4.8 -x)
460 x = 2400 - 500x
900 x = 2400
x = 2.5 hours for the slower plane.
4.8- x = 2.3 hours for the faster plane.
