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

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.

Answer:
You just find the volume of the cup and subtract the volume of the froth (whatever that is).
V(cup) = pi * r^2 * h
...........= pi * 4.3^2 * 11.2
...........= 650.586cm^3
V(froth) = pi*r^2*h
............= pi*4.3^2*0.4
.............=23.232cm^3
V(hot chocolate) = V(cup) - V(froth)
.........................= 650.586 - 23.232
.........................= 627cm^3
18 percent of what number is 74
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
share 660kg in ratio of 5:7
5x+7x=660;
12x=660;
x=660:12;
x=55 (kg).
Then 5x=5×55=275 kg and 7x=7×55= 385 kg.
The required ratio is therefore
660= 275:385.

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

Answer:
Area = 201 1/4 yard^2
Or in decimal form: 201.25 yard^2
Step-by-step explanation:
First convert the mixed numbers into improper fractions or even decimal form so it is easier to operate with them:
Base = 11 1/2 yards = 23/2 yards = 11.5 yards
Height = 17 1/2 yards = 35/2 yards = 17.5 yards
Use the formula for the area of a parallelogram:
Area = Base x Height
which in our case give:
Area = 23/2 x 35/2 = 805/4 yard^2 = 201 1/4 yard^2
Or in decimal form: 201.25 yard^2

Rewrite as a simplified fraction. 0.51 = ?
the one is repeating btw
Answer:
17/33
Step-by-step explanation:
100 x = 51.51
100 x − x = 51.51 − 0.51
99 x = 51
divide both sides by 99 to get x as a fraction.
x=51/99
=17/33

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 .
