a jumbo tablet in the shape of a rectangle has a perimeter of 50 inches. The tablet is 7 inches less wide than it is long. find the length and width of the tablet. help plzz

Answers

Answer 1
in rectangles, opposite sides are equal.
lets name the length as x
as stated in the question, width is 7 less than the length 
therefore length is --> x-7
perimeter = 2*(length) + 2(width)
substituting length and width 
perimeter = 2x +2(x-7)
as the perimeter given is 50 inches
70 = 2x + 2x - 14
4x = 84
x = 21 inches 
length of tablet - 21 inches 
width of tablet - 14 inches 
Answer 2

Answer:

Length = 16 inches and width = 9 inches

Step-by-step explanation:

The perimeter of a rectangle table = 50 inches

Rectangle table has equal sides of length and equal sides of width.

Let the length of the table be x.

It is given in the question that the table is 7 inches less wide than it is long.

So width of the table = x - 7

Perimeter = 2(length) + 2(width)

Perimeter = 2(x) + 2(x-7) = 50

                = 2x + (2)(x) + (2)(-7) = 50

                = 2x + 2x + (-14) = 50

                = 4x -14 = 50

                =  4x = 64

                 x = 16

Length = 16 inch Width = 16 - 7 = 9 inches

perimeter = 2(16) + 2(9) = 50 inches

Aldo drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 8 hours. When Aldo drove home, there was no traffic and the trip only took 5 hours. If his average rate was 21 miles per hour faster on the trip home, how far away does Aldo live from the mountains? Do not do any rounding.

Answers

8x = 5(x+21)
8x = 5x +105
3x = 105
x = 105 /3
x = 35

8 x 35 = 280 miles away

The distance of Aldo's house from the mountains when calculated using the parameters is; 280 miles

How to Solve Algebra Word Problems?

We know that distance is given by;

Distance = speed * time

Distance with traffic = 8x

Distance without Traffic plus average rate = 5(x + 21)

Thus;

8x = 5(x + 21)

8x = 5x + 105

3x = 105

x = 105/3

x = 35

Thus;

Distance from his house = 5(35 + 21) = 280 miles

Manny Brought a brand new car in 2012 for $28750. if the car depreciates by 12% each year, write n exponential function to model the situation, then find the value of the car in 2018

Answers

The formula for exponential decay is 
[tex]y=a(1-r)^{x} [/tex]

where  a is the initial value (28750)
r is the rate of decrease (0.12)
x is the time, in this case in years (6 .  2018-2012 = 6 years)

[tex]y=28750(1-0.12)^{6} [/tex]

y ≈ 13351.62

Value of the car in 2018 after depreciation by 12% each year is equals to $13351.5

What is exponential decay?

" Exponential decay is the decrease in the value of the product at a constant rate over a period of time interval."

Formula used

y = a (1 - r)ⁿ

a = Initial value

r =rate of depreciation

n = time

y = exponential function

According to the question,

Cost of new car 'a' = $28750

Rate of depreciation 'r' = 12%

2018 - 2012 = 6years

n = 6

Substitute the given values in the formula we get,

Exponential function

    y = 28750 [1 - (12 / 100)]⁶

⇒ y = 28750 ( 1 - 0.12)⁶

⇒ y = 28750 ( 0.88)⁶

⇒ y = 28750 (0.4644)   ( up to four decimals)

⇒ y = $13351.5

Hence, value of the car in 2018 after depreciation by 12% each year is equals to $13351.5

A metronome uses a pendulum to keep time. The table gives the angular displacement of a pendulum as it swings back and forth. What is the period of its oscillations?

0.1 2.55
0.2 -14.4
0.3 -7.35
0.4 11.6
0.5 11.3

Answers

Answer: With the given information, it appears that the period of the pendulum is about 0.45 seconds.

The period is the length of one complete cycle of the pendulum. That mean that is will start positive go negative and return to positive. 

If we assume that time 0 is the start with an angle of 15  degree, then we are looking for the point in the graph where it returns to about 15 degrees.

If you create a scatter plot of the data, it would appear that it would reach 15 between 0.4 and 0.5 seconds. At 0.4 it is at 11.6, then it moves up. At 0.5, it is on it's way down at 11.3.

It is safe to assume that it reached 15 between these points to complete one period.

Given the lease terms below, find the total lease cost, assuming that the deposit is nonrefundable.
Terms:
Length of lease: 36 months
MSRP of the car: $21,400
Purchase value of the car after lease: $17,100
Down payment: $1500
Monthly payment: $272
Security deposit: $350
Acquisition fee: $700

Answers

Answer: The total cost of the lease is $12,342.

To find the total cost of the lease, we have to add up all the costs that you will be responsible for.

You will have to pay the down payment, the monthly payment, security deposit and the acquisition fee.

However, don't forget that you have to multiply the monthly payment by 36 months.

1500 + 36(272) + 350 + 700 =12342

Final answer:

The total lease cost is the sum of the down payment, nonrefundable security deposit, acquisition fee, and the total payments over the lease term which amounts to $12,342.

Explanation:

The total lease cost can be calculated by adding all fees, the nonrefundable deposit, monthly payments, and any other additional costs. We start by adding the down payment, security deposit, and acquisition fee:

Down payment: $1500Security deposit (nonrefundable): $350Acquisition fee: $700

The monthly payment over the term of the lease is calculated by multiplying the monthly payment amount by the number of months in the lease term:

Monthly payment: $272Length of lease: 36 months

Multiplying the monthly payment by the lease term gives us the total amount paid over the course of the lease:

272 * 36 = $9792

Adding all the costs together gives us the total lease cost:

Total lease cost = Down payment + Security deposit + Acquisition fee + Total monthly paymentsTotal lease cost = $1500 + $350 + $700 + $9792Total lease cost = $12342

Note that this calculation assumes that the security deposit is nonrefundable, which is often the case in a car lease. It's also important to note that additional costs may apply, such as excess mileage fees or wear and tear.

The result of dividing [tex](5x^3y^3z - 6x^4y^2z^2 + 4xy^3z)[/tex] by xyz is [tex](5x^2y^2 - 6x^3yz + 4y^2z).[/tex]

Explanation:

To divide [tex](5x^3y^3z - 6x^4y^2z^2 + 4xy^3z)[/tex] by xyz, we'll divide each term in the polynomial by xyz separately.

First, let's divide [tex]5x^3y^3z by xyz: (5x^3y^3z) / (xyz) = 5x^2y^2.[/tex]

Then, divide [tex]-6x^4y^2z^2 by xyz: (-6x^4y^2z^2) / (xyz) = -6x^3yz.[/tex]

Lastly, divide [tex]4xy^3z by xyz: (4xy^3z) / (xyz) = 4y^2z.[/tex]

Thus, the resulting polynomial after division is [tex]5x^2y^2 - 6x^3yz + 4y^2z.[/tex]This is derived from individually dividing each term in the polynomial by xyz, simplifying each term, and collecting like terms together to obtain the final result.

In this process, division by xyz means dividing each term of the polynomial by the factors x, y, and z, and simplifying the expression. By doing so, we obtain a simplified form of the polynomial where each term is reduced by the common factors x, y, and z, resulting in the expression [tex](5x^2y^2 - 6x^3yz + 4y^2z)[/tex] as the quotient.

Kendall assumed the 2y^2 was negative and not positive leading her to create the error of -5y^2

Hope this helps :)
Final answer:

The error made was in the summation of the y^2 terms in each expression, leading to an incorrect final sum of the two expressions.

Explanation:

Kendall's error lies in incorrectly adding the terms that contain y^2. Specifically, Kendall summed 2y^2 from the first expression and -3y^2 from the second expression, but mistakenly calculated the result as -5y^2 instead of the correct -y^2. Remember, when performing operations with similar terms, you must carry the correct sign along with each term.

So, the correct sum of (6x^2+4xy+2y^2) and (4x^2-2xy-3y^2) is (10x^2+2xy-y^2).

Answers

The answer is A- High Values of one variable are associated with low values of the other.
Negative correlation is a relationship between two variables wherein if the value of one variable increases, the value of the other variable decreases, and vice versa.
Final answer:

A negative correlation means that high values of one variable are associated with low values of the other. This suggests that as one variable increases, the other decreases respectively and vice versa, which can be seen in various real-world scenarios such as the relationship between time spent studying and number of mistakes made on a test.

Explanation:

In the context of statistics and data analysis, a negative correlation means that high values of one variable are associated with low values of the other. This implies that as one variable increases, the other decreases correspondingly and vice versa. For instance, if we were examining the relationship between time spent studying and number of mistakes made on a test, a negative correlation might indicate that the more time a student spends studying, the fewer mistakes they make on the test. This is indicative of a negative correlation because as the value of one variable (study time) increases, the value of the other variable (mistakes) decreases.
