The length of a rectangle is 7mm longer than its width. It’s perimeter is more than 62mm. Let W equal the width of the rectangle, write an inequality and solve it
Answers
2(l + w) = p
Since we know the perimeter (p) is greater than 62 we can say:
2(l + w) > 62
It is also given that the length is 7 mm longer than the width, so we know the value of the length in terms of w (the width).
w = w
l = w + 7
Substitute l with (w + 7) into the equation:
2[(w + 7) + w] > 62
Now combine like terms in the parentheses
2(2w + 7) >62
Distribute the 2 into the terms in the parentheses
4w + 14 > 62
Subtract both sides by 14
4w > 62 - 14
Combine like terms
4w > 48
Divide both sides by 4
w > 48
Final answer: w > 48
Hope this helps!

A negative correlation means that ________. select one:
a. high values of one variable are associated with low values of the other
b. high values of one variable are associated with high values of the other
c. low values of one variable are associated with low values of the other
d. there is no relationship between the two variables
Answers
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.
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.

The engine of a car has a displacement of 305 cubic inches. what is the displacement in cubic feet? round your answer to 2 decimal places.
Answers
1 inch = 2.54 centimeters
Therefore, to convert to cubic measurements
(1 in)³ = (2.54 cm)³
Thus;
1 in³ = 16.387 cm³
Hence 305 cubic inches will be equivalent to
305 × 16.387
= 4998.035 cm³
Answer:
0.18 cubic feet (in 2 decimal places)
Step-by-step explanation:
The relationship between the unit of measurement inches and the unit of measurement feet may be expressed mathematically as
12 Inches = 1 feet
finding the cube of both sides i.e both sides to the power of 3,
1728 cubic inches = 1 cubic feet
therefore,
305 cubic inches
= 305/1728 cubic feet
= 0.1765 cubic feet

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
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
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: $700The 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 monthsMultiplying the monthly payment by the lease term gives us the total amount paid over the course of the lease:
272 * 36 = $9792Adding 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 = $12342Note 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.

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
[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

Answers
=
(10x^2 + 4xy - y^2)
Kendall assumed the 2y^2 was negative and not positive leading her to create the error of -5y^2
Hope this helps :)
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).

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 = 5x +105

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.

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.
