You are deciding between two laptops to purchase. The first laptop has an initial value
of $2000 but loses 14% of its value every year. The second laptop has an initial value
of $1200 but loses 11% of its value every year.
a. Write functions that represent the values (in dollars) of the laptops after t years.
Then graph the functions in the same coordinate plane.
b. Find the approximate monthly percent decrease in value for each laptop.
C. Which laptop should you buy if you plan on selling the laptop in 5 years? Explain
your reasoning
Step-by-step explanation:
a)
The first laptop
Initial value- $2000Value loss - 14% every yearFunction for value- V(t) = 2000*0.86^tThe second laptop
Initial value- $1200Value loss - 11% every yearFunction- V(t) = 1200*0.89^tb)
Monthly percent decrease
The first laptop:
14%/12 = 1.16%The second laptop:
11%/12 = 0.92%c)
The second laptop will lose less value in 5 years hence is better choice

The slope of the Line (): 3y−4x+3=0 is:

4/3
-4
Answer:
[tex]\displaystyle \frac{4}{3}[/tex]
Step-by-step explanation:
[tex]\displaystyle 3y - 4x + 3 = 0 → 3y - 4x = -3 → 3y = 4x - 3 \\ \\ y = 1\frac{1}{3}x - 1[/tex]
When converted to Slope-Intercept Form, it is alot easier to determine the rate of change [slope] of the function because [tex]\displaystyle b[/tex] is the y-intercept, and the slope is represented by [tex]\displaystyle m,[/tex] which in this case is [tex]\displaystyle 1\frac{1}{3}, or\: \frac{4}{3}.[/tex]

Eric´s mother drives to work in 20 min when driving at her usual speed. When traffic is bad, she drives 10 miles per hour slower, and the trip takes 10 minutes longer. What is Eric´s mother´s usual speed?
Answer:
30
Step-by-step explanation:
I could be wrong
The usual speed of Eric's mother is 4 miles per hour .
Eric´s mother drives to work in 20 min when driving at her usual speed.
Let the usual speed of Eric's mother be "u" miles per hour (mph)
When the traffic is bad she drives 10 miles per hour slower.
The speed of Eric's mother when the traffic is bad = u-10 mph
The time taken by Eric's mother when the traffic is bad = 30 min
[tex]\rm Displacement = \dfrac{Velocity }{Time }[/tex]
The considering the displacement in both the cases is same hence we can
say that
[tex]\rm \dfrac{u}{20/60} = \dfrac{-(u-10)}{30/60} \\\rm 3u = -2u +20 \\5u = 20 \\u = 4[/tex]
So the usual speed of Eric's mother is 4 miles per hour .

Orange colors - Why are the locations of the police station and fire department congruent?
blue colors - Why are the locations of the restaurant and bank congruent?
Answer:
Step-by-step explanation:
Congruent are angles that are in identical angles. For example the orange colors are congruent because both of the angles are across each other, and because of them being crossed they are both the same degrees making the congruent, same with the blue but instead of being across eachother they are in the angle to the left of the parallel lines that are the same degrees as well.

8(5 + 4n) + 11 = -5(3 - 7n)
Isolate the variable by dividing each side by factors that don't contain the variable.
n = 22
Answer:
n=22
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8(5+4n)+11=−5(3−7n)
(8)(5)+(8)(4n)+11=(−5)(3)+(−5)(−7n)(Distribute)
40+32n+11=−15+35n
(32n)+(40+11)=35n−15(Combine Like Terms)
32n+51=35n−15
32n+51=35n−15
Step 2: Subtract 35n from both sides.
32n+51−35n=35n−15−35n
−3n+51=−15
Step 3: Subtract 51 from both sides.
−3n+51−51=−15−51
−3n=−66
Step 4: Divide both sides by -3.
−3n /−3 = −66 /−3
n=22

The stage manager of a school musical is trying to figure out how many sandwiches he can order with the $83 he collected from the cast and crew. Sandwiches cost $5.99 each, so he lets x represent the number of sandwiches he will order and writes 5.99x < 83. He solves this to two decimal places and gets x < 13.86.
Which of these are valid statements about this situation? Select all that apply.
1) He can call the sandwich shop and order exactly 13.86 sandwiches.
2) He can round up and order 14 sandwiches.
3) He can order 12 sandwiches.
4) He can order 9.5 sandwiches.
5) He can order 2 sandwiches.
6) He can order -4 sandwiches.
Justify your answer(s).
Answer:
Step-by-step explanation:
1) it is not this answer because you cant order 13.86 sandwiches. it has to be a whole number.
2) Not this answer. If he bought 14 sandwhichs hed have to pay 83.86 and he doesnt have 36 cents xtra.
3) He CAN order 12 sandwhiches. if he has $83 and if you bought twelve sandwiches he would spend $71.88 which is still within the range he can buy from.
4) He CANNOT order .5 of a sandwhich so i wouldnt select this one.
5) He CAN order 2 sandwhiches. he has enough money for that
6) he CANNOT order negative amount of sandwhiches.

Answer:
411.1111111
Step-by-step explanation:
18% of x = 74
Convert 18% into a decimal.
0.18 • x = 74
Isolate x by dividing by 0.18.
x = 411.1111111
Check answer.
0.18 • 411.1111111 = 74
74 = 74
A television sells for $700. Instead of paying the total amount at the time of the purchase, the same television can be bought by paying $200 down and $50 a month for 14 months. How much is saved by paying the total amount at the time of the purchase?
Step-by-step explanation:
It's 200$
50×14=700+200=900
900-700=200$
$200 is saved by paying the total amount at the time of the purchase.
Given that, a television sells for $700. Instead of paying the total amount at the time of the purchase, the same television can be bought by paying $200 down and $50 a month for 14 months.
We need to find how much is saved by paying the total amount at the time of the purchase.
What is the selling price?The selling price of something is the price for which it is sold. The difference between buying and selling prices is called the spread.
The cost price of television=200+50×14=200+700=$900
The money saved by paying the total amount =900-700=$200
Therefore, $200 is saved by paying the total amount at the time of the purchase.

Cost of a dozen pens is ₹ 180 and cost of 8 ball pens is ₹ 56. Find the ratio of the
cost of a pen to the cost of a ball pen. [1 ½ m]
Answer:
Ratio of cost of a pen to cost of a ball pen is 15:7
Step-by-step explanation:
Given that:
Cost of dozen pens = ₹180
Unit rate = [tex]\frac{180}{12}[/tex]
Unit rate = ₹ 15 per pen
Cost of 8 ball pens = ₹ 56
Unit rate = [tex]\frac{56}{8}[/tex]
Unit rate = ₹7 per ball pen
Ratio of cost of a pen to cost of a ball pen,
15 : 7
Hence,
Ratio of cost of a pen to cost of a ball pen is 15:7
