The current price index is mathematically given as,$538.194

By increasing the ratio of the current value to the reference value by 100, one can determine the index value.

Given that the current cost of gasoline is $3.10 per gallon. we need to find the current price index number, using the 1975 price of 56.7 cents as the reference value.

In regard to this issue, we have that:

Current value = $3.10

Reference value: $0.576

Typically, the mathematical formula for the Index price is,

I = (3.10/0.576) x 100

I= $538.194

The current price index number is 538.194

Answer:

Let width of rectangle be x cm.

Width = x cm

Length = 4x cm

Area of rectangle = length x width

4x × x = 144

4x² = 144

x² = 144 ÷ 4 = 36

x = √36 = 6

Width = 6 cm

Length = 6 × 4 = 24cm

Perimeter = 6 + 24 + 6 + 24 = 60 cm

Answer:

Part a: x + 17 = 52    Part b: He should guess the number 35.

Step-by-step explanation:

In the equation, x stands for the number he has to guess. He is given the clue, "17 more than the number is 52." Therefore x + 17 = 52. Another equation you could use is 52 - 17 = x. This equation would be used to solve the problem. 52 - 17 = 35

The annual rate of change of the boat's value is $5334.

Given,

Chris bought a new boat in 2008.

The value of boat in 2008 (Initial value) = $35000

The value of boat in 2011 = $19000

Chris knows that the value of the boat depreciated linearly.

We have to find the annual rate of change of the boat's value, x.

Number of years, n = 2008 to 2011 = 3 years

Here, x be a constant.

So,

Value in 2011 = Initial value - nx

19000 = 35000 - 3x

3x = 35000 - 19000

3x = 16000

x = 16000/3

x = 5333.33

x = 5334

there is no proportional relationship between the two qualities

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

We are asked to solve for a number such that:

Twice that number plus 4 equals 6

Which can be written in math terms as:

2 x + 4 = 6

Now we proceed to isolate the unknown in steps.

First we subtract 4 from both sides:

2 x + 4 - 4 = 6 + 4

we combine like terms:

2 x = 10

Now we divide both sides by 2 so as to cancel the factor 2 that accompanies "x":

2 x / 2 = 10/ 2

perform the indicated operations:

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

Total Interest = $220,010.40

Actual monthly payment =  $933.36

Estimated monthly payment 870.00

Difference = $63.36

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.

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

P – To find

Substituting the values we get

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

Answer:

  (a) ∠e +∠d = 180°  is false

Step-by-step explanation:

You want to know which angle expression is not true.

We can figure the measures of all of the unknown angles, then check the given expressions.

Angles 'a' and 130° are corresponding angles, so congruent:

  a = 130°

Angles 'a' and 'e' are vertical angles, so congruent:

  e = a = 130°

Angle 'd' and 62° are vertical angles, so congruent:

  d = 62°

Angles 'b' and 'd' are corresponding angles, so congruent:

  b = d = 62°

Angles 'f' and 62° are corresponding angles, so congruent:

  f = 62°

Angles 'c' and 130° are a linear pair, so supplementary:

  c + 130° = 180°

  c = 50° . . . . . . subtract 130°

(a) ∠e +∠d = 180°   ⇒   130° +62° = 180° . . . . false

(b) ∠d +∠b = 124°   ⇒   62° +62° = 124° . . . . true

(c) ∠a +∠c = 180°   ⇒   130° +50° = 180° . . . . true

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.
