the length of a rectangle is four times it's width. if the perimeter is at most 106 centimeters, what is the greatest possible value for the width?
Lenght of a rectangle: L
Widht of the rectangle: W
Perimeter of the rectangle: P
length of a rectangle is four times it's width: L = 4W
Perimeter is at most 106: P <= 106
Perimeter is 2L + 2W: P = 2L + 2W
P <= 106
if we use the value of P = 2L + 2W, we can write:
2L + 2W <= 106
Since L = 4W, then we can write this equation:
2L + 2W <= 106
2(4W) + 2W <= 106
8W + 2W <= 106
10W <= 106
W <= 106/10 = 10.6
W <= 10.6
Therefore, the greatest possible value for the width is 10.6

Using the sinking fund formula, the monthly payment needed to accumulate 270,000 with 5% interest or combine did monthly for 28 years, the monthly invested payment is 369.65.
What is sinking fund formula?A sinking fund, also referred to as a sinking fund, is defined by its name. Fundamentally speaking, it is built to sink. Although there are some similarities between a sinking fund and a reserve fund, their purposes differ significantly. Unlike reserve funds, which typically serve no particular purpose, sinking funds have a designated purpose.
Simply put, a reserve fund is a company's method of saving its surplus funds. There are numerous uses for reserve funds. They can be applied to a variety of costs, including those related to emergency situations, asset purchases, business expansions, and capital expenditures.
Sinking fund (A) = P × [tex]\frac{(1+r/n)^{tn}-1}{r/n}[/tex]
Where
A – Money accumulated
P – Periodic contribution,
r – Interest rate
t – Number of years
n – Number of payments per year
So, periodic contribution P = A / (((1 + r / n) ^ (t * n) – 1) / (r / n))
Here given that,
A – 270,000
r – 5%
t – 28 years
n – 12

Russell works at a football concession stand selling drinks for $2 and bags of chips for $3. At one football game, Russell makes a total of $246 and sells a total of 100 drinks and bags of chips.
The number of chips and drinks are 46 chips and 56 drinks respectively.
How to calculate the values?Let the number of drinks be d.
Let the number of chips be c.
From the information, he works at a football concession stand selling drinks for $2 and bags of chips for $3 and he makes a total of $246 and sells a total of 100 drinks and bags of chips.
This will be:
c + d = 100 ........ i
2d + 3c = 246 ........ ii
From equation i, c = 100 - d
Substitute this into equation ii
2d + 3c = 246
2d + 3(100 - d) = 246
2d + 300 - 3d = 246
Collect like terms
2d - 3d = 246 - 300
-d = -54
d = 54
Number of drinks = 54
Since c + d = 100
c + 54 = 100
c = 100 - 54 = 46

There are 4 boxes arranged in a square with 2 boxes side-by-side directly on top of the other 2 boxes. There is a horizontal line representing a fraction bar separating the top 2 boxes from the bottom 2 boxes.
Some committee members contend this is not a valid question.
Solve the problem. (If there is no solution, enter NO SOLUTION.)
Explain the solution to prove (or disprove) the question's validity.
The question is valid because to make the fraction as small as possible, you make the numerator as small as possible and make the denominator as large as possible.The question is valid because to make the fraction as small as possible, you make the numerator as large as possible and make the denominator as small as possible.

Answer:
no solution that's my answer
The valid solution to the problem is: The smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8 is 34/85.The smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8 is 34/85.
Let's solve the problem step by step to determine the smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8. We'll express the answer as a reduced fraction.
We have 4 boxes arranged in a square as described:
A B
C D
The fraction can be represented as AB/CD.
To make the fraction as small as possible, we need to arrange the digits in a specific way. We want to minimize the numerator (AB) and maximize the denominator (CD).
For the numerator (AB), we want the smallest two-digit number. The smallest two-digit number that can be formed using the digits 3, 4, 5, and 8 is 34.
For the denominator (CD), we want the largest two-digit number. The largest two-digit number that can be formed using the digits 3, 4, 5, and 8 is 85.
Therefore, the smallest fraction that can be formed is 34/85.
To ensure that this fraction cannot be further reduced, we need to check if 34 and 85 share any common factors greater than 1. If they do not share any common factors other than 1, then the fraction is in its reduced form.
Checking for common factors:
Factors of 34: 1, 2, 17, 34
Factors of 85: 1, 5, 17, 85
The only common factor is 1, which means the fraction 34/85 is already in its reduced form.
Thus, the valid solution to the problem is:
The smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8 is 34/85.

A phone keeps track of the number of steps taken and the distance traveled. based on the information in the table, is there a proportional relationship between the two qualities?
there is no proportional relationship between the two qualities
Explanation:For two quantities to be proportional, it must follow the formula:
y = kx
where k = proiportionality constant
k = y/x
if y = 950, x = 1
inserting in the equation:
950= 1k
k = 950
The equation becomes: y = 950 × x
We check for other values. if k is the same, it is proportional
when y = 2852, x = 3
2852 = k × 3
k = 2852/3 = 950.67
when y = 5.1, x = 4845
4845 = k × 5.1
k = 4845/5.1 = 950
From the above, the value of k which is different is for the 2nd value.
Since they are not all the same, we say there is no proportional relationship between the two qualities

Rounding in the calculation of monthly interest rates is discouraged. Such rounding can lead to answers different from those presented here. For long-term loans, the differences may be pronounced.
Several years ago Bill got a home mortgage of $116,000 with a term of 30 years at an APR of 9%. Use the Monthly Payments for Long-Term Loans Rule of Thumb to estimate his monthly payment.
$
Compare this estimate with what the monthly payment formula gives. (Round your answer to the nearest integer.)
The actual monthly payment is about $
greater than the estimated payment.
Bill's projected monthly payment under the Monthly Payments for Long-Term Loans using the Rule of Thumb is $870.00.
Bill's exact monthly payment using the Monthly Payments calculation is $933.36.
The real monthly payment is approximately $63.36 more than the predicted cost.
Simple procedures may be used to calculate the Monthly Payments for Long-Term Loans Rule of Thumb.
To begin, divide the annual percentage rate (APR) by 12 to obtain the monthly percentage rate (MPR).
Second, calculate the MPR on the principal amount. The product is the estimated monthly payment, which is similar to the real monthly payment and was computed using a financial calculator below.
Estimated Monthly Payment:
Home Mortgage = $116,000
Term of loan = 30 years
APR = 9%
Monthly interest rate = 0.0075 (0.09/12)
Estimated monthly payment based on the Monthly Payments for Long-Term Loans Rule of Thumb
($116,000 x 0.0075) = $870
Actual Monthly Payment Formula:
N (# of periods) = 360 months (30 x 12)
I/Y (Interest per year) = 9%
PV (Present Value) = $116,000
FV (Future Value) = $0
The outcome is given as:
PMT = $-933.36
Sum of all periodic payments = $-336,010.40

if m/A and m/B are equal, to find x, your equation would be 20x+10=30x-10. doing two step equations, you would substract 20x from both sides, making your equation look like 10=10x-10. then you would add 10 from both sides making your equation 20=10x. then you would divide 10x from both sides making x=2.
Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 7 liters of natural oil for every 4 liters of synthetic oil. In order to make 671 liters of Petrolyn oil, how many liters of synthetic oil are needed?
For every 4 liters of synthetic oil, there are 7 liters of natural oil. 671 liters of Petrolyn oil. 244 liters of synthetic oil is needed and 427 liters of natural oil is needed.
Given that,
Petrolyn motor oil is a blend of synthetic and natural oil. For every 4 liters of synthetic oil, there are 7 liters of natural oil. 671 liters of Petrolyn oil are needed to produce it.
We have to find how much synthetic oil, in liters, is required.
According to the given values;
The ratio of natural to synthetic oil
= 7:4
If 671 liters have to be made then,
By adding 7+4=11
So, 7/11 of 671 liters will be = 427 liters of natural oil
and, 4/11 of 671 liters will be = 244 liters of synthetic oil
Therefore,244 liters of synthetic oil is needed and 427 liters of natural oil is needed.
