The length of the bridge that connect the two cities separated by the lake is 3.4 miles.

The mathematical operation that would be used to convert yards to miles is division. Division is the process of putting a number into equal groups using another number. For example, when 6 is divided by 3, 3 divides 6 into 2 equal groups.

In order to convert yards to miles, divide the given length in yards by 1760.

1 yard = 1 / 1760 miles

5927.61 / 1760  = 3.36796 miles

The cost of the watch which sold at 130% of its cost and sale price is $39 is equal to $30.

As given in the question,

Sale price of the watch for which dealer sold = $39

Let $'x' be the cost of the watch with which dealer purchase

A dealer sold a watch 130% of its cost

Required expression to show the given condition of a dealer is given by:

   130% of x = $39

⇒ (130 /100) × x = $39

⇒ x = ( 39 × 100 ) / 130

⇒ x = $30

Therefore, the cost of the watch which sold at 130% of its cost and sale price is $39 is equal to $30.

From the provided information we get that Ava's Pin code is 8842.

Ava's pin code is a 4-digit number.

Let the first digit = x                                      equation 1

Reading from left to right, the first and second digits are the same. So,

Second digit = x                                            equation 2

Let, third digit = y

The second digit is twice the third digit. So,

x = 2y

⇒ y = x/2

Third digit = x/2                                            equation 3

Let, fourth digit = z

The first digit is four times the fourth digit. So,

x = 4z

⇒ z = x/4

Fourth digit = x/4                                            equation 4

Sum of the four digits is 22. So, using equation 1 , equation 2 , equation 3 and equation 4 , we can write

x + x + (x/2) + (x/4) = 22

2x + (x/2) + (x/4) = 22

Multiplying both sides by 4 , we get

8x + 2x + x = 88

11x = 88

x = 8

First digit = x = 8

Second digit = x = 8

Third digit = x/2 = 8/2 = 4

Fourth digit = x/4 = 8/4 = 2

So, we can conclude that the Ava's Pin code is 8842.

Answer:

The top set does not represent a function because -4 corresponds to two y-values.

The amount of IRA when he will retire at age 65 = $83448.27

And the total deposits made over the time period is less than the the amount of IRA

We have been given, at age 19​, someone sets up an IRA​ (individual retirement​ account) with an APR of7 ​%. At the end of each month he deposits ​$20.00 in the account.

We need to find the IRA when he retires at age​ 65.

here, 65 - 19 = 46 years

So, the period would be,

46 × 12 = 552 months

Monthly deposit= $20

And the interest rate would be,

Interest = 0.07/12

             = 0.0058

To calculate the future value, we need to use the following formula:

FV= {A × [(1 + i)^n-1]} / i

A= monthly deposit

i = interest rate

n = period

So, the Future Value of Annuity

= 20 × ([1 + 0.0058]^552 - 1 ) / (0.0058)

= 20 × 24.2 / 0.0058

= $83448.27

So, the amount of IRA when he will retire = $83448.27

Deposits made over the time period = 20 × 46 × 12 = $‭11040

Difference = 83448.27 - 11040

= $72408.27

This means, the total deposits made over the time period is less than the the amount of IRA he will get when he retires at age 65.

Therefore, the amount of IRA when he will retire at age 65 = $83448.27

And the total deposits made over the time period is less than the the amount of IRA

Answer:

y = 15x - 30

Hope this helps!

Step-by-step explanation:

The slope can be found with the equation [tex]\frac{y_{2} -y_{1} }{x_{2} - x_{1} }[/tex].

Add in the numbers from the two points to get [tex]\frac{15-0}{3-2}[/tex] which is [tex]\frac{15}{1}[/tex] : 15.

That means slope is 15. To get the other numbers, you can do y = 15x and then plug in one of the points, for example (0) = 15(2), which is 0 = 30. To make this equation true, you need to minus 30 so it would be 0 = 30 - 30 and this is true, so putting it all together would get y = 15x - 30.

Based on the direct variation between x and y, the value of y is 48

The given statements are:

From the above points, we understand that:

The variation is a direct variation

A direct variation is represented as

y = kx

Where k represents the constant of variation

The above equation is a linear equation

As a general rule, linear equations are equations that have constant average rates of change.

So, we have

y = kx

y is 120 when x is 15

This means that

120 = 15k

Divide by 15

k = 8

So, we have

y = 8x

The value of y when x is 6 is

y = 8 x 6

Evaluate

y = 48

Hence, the value of y when the value of x is 6 is 42

In linear relationship, 199.333 million dollers per year is the percent growth rate.

What is linear relationship in math?

Given , t Rs numbers of year since 1997 .

t = 0 corresponds to year 1997

t = 6 corresponds to year 2003

Let  s(t) = sales of the year

So, given that

 sales in 19997 is  $2503 millions

so    s(0) = 2503  million dollers

Sales in 2003 is $3699 millions

so  s(6) = 3699  million dollers

Now apply formula of linear relation ship

               s - s(0) = s(6) - s(0)/6 - 0 ( t - 0)

               s - 2503 = 3699 - 2503/6 (t)

                s = 1196* t /6 + 2503

  so         s(t) = 598t/3 + 2503

 so now average rate of change of function over on interval is given by

                 =     s(b) - s(a)/b - a

                 = s(6) -  s( 0)/6 - 0

                 = 3699 - 2503/6

                 = 598/3

                 = 199.333 million dollers per year .

a. The answer to the subject of the formula, "d," is d = P/64.

b. A submerged object will be 10. 5 feet deep at a pressure of 672 pounds per square foot.

A function can be defined as an expression, law or rule that shows the relationship between two variables.

These variables are namely;

given the role as;

P = 64d

Where;

P stands for pounds per square foot of pressure.

d represents the object's depth in feet.

Let's now make the variable "d" the focus of the formula.

The coefficient of the variable "d," which is 64, is used to divide both sides of the equation. So that the variable can stand on its own, this is done.

We get,

P/64 = 64d/64

d = P/ 64

P equals 672 pounds per square foot if there is pressure.

When the variable's value is substituted into the formula, we get;

d = P/64

Then,

d = 672/64

Discover the quotient.

d = 10. 5 ft.

The value is 10.5 feet.

Therefore,

a. The answer to the subject of the formula, "d," is d = P/64.

Based on the interest compounded by the bank monthly, and the amount deposited by Sean in the account, the amount of money that will be in that account in a year is $3,668.09

First, find the monthly rate because the interest is compounded monthly:
= 4.7% / 12

= 4.7/12 %

The number of periods would be:

= 1 x 12 months a year

= 12 periods

The amount that Sean will have in a year can be found by the formula:

= Amount invested x (1 + periodic rate) ^ number of periods

Solving for the amount in the account after 1 year gives:
= 3,500 x (1 + 4.7%/12) ^ 12

= 3,500 x 1.0480257937581146250656044647993
