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

8(5 + 4n) + 11 = -5(3 - 7n)

Answers

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

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?

Answers

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?​

Answers

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.

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

Answers

Step-by-step explanation:

a)

The first laptop

Initial value- $2000Value loss - 14% every yearFunction for value-  V(t) = 2000*0.86^t

The second laptop

Initial value- $1200Value loss - 11% every yearFunction- V(t) = 1200*0.89^t

b)

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
