The formula predicting the number of US billionaires in any given year (t) is:f(t) = 17.2t - 34,129. We can assume a linear growth model on the based of given information.

The given data states that in the year 1985, there were 13 US billionaires. Whereas in 1990, there were 99 US billionaires. We have to find out the formula that predicts the number of US billionaires in any given year (t).

The yearly increase remains constant, so we can consider the formula for the linear function.f(t) = mt + b

where

t is the year and f(t) is the number of US billionaires in that year (t).

m is the slope of the line and b is the y-intercept.

The slope of the line is given by the formula:m = (y₂ - y₁) / (x₂ - x₁)

Let's plug in the given values to find the slope of the line.m = (99 - 13) / (1990 - 1985)m = 86 / 5m = 17.2 .The y-intercept of the line can be found by substituting the values of t and f(t) from any of the given points into the equation of the line.

Let's use the point (1985, 13).f(t) = mt + b => f(1985) =17.2(1985) + b => f(1985) = 34,142 + b =>b = 13 - 34,142 & b = -34,129.

The formula predicting the number of US billionaires in any given year (t) is:f(t) = 17.2t - 34,129

A: The height of the street sign is obtained by indirect measurement method as 15 feet.

B: The two proportions Betsy can use is 5/1.5 = x/4.5 and 5/.x = 1.5/4.5

C: Using both the proportions height of the street sign is obtained as 15 feet.

What is indirect measurement?

A mathematical technique called as an indirect measurement is used to discover unknown measures of items that are challenging to measure. A direct measurement is something that can easily be measured, like a toddler's height.

The height of Betsy is h = 5 feet.

The shadow of Betsy is h' = 1.5 feet.

The height of the street sign is H = x feet.

The height of the shadow of street sign is H' = 4.5 feet.

The two proportions are -

h/h' = H/H' and h/H = h'/H'

These two can be used to find the measurement of the street sign.

To find the height of the street sign use the method of indirect measurement -

h/h' = H/H'     h/H = h'/H'

Substitute the values in the given equation -

5/1.5 = x/4.5            5/x = 1.5/4.5  

1.5 × x = 5 × 4.5      5 × 4.5 = 1.5 × x

1.5x = 22.5              22.5 = 1.5x

Simplify the equation further -

x = 22.5/1.5             x = 22.5/1.5

x = 15                       x = 15

Therefore, the value of the x is obtained as 15 feet.

The range at which Dan's car can go is 3.33 miles

A car's range is the distance it can travel with the current amount of fuel in the tank.

The vehicle calculates the range based on the amount of fuel, how the accelerator and brakes are used, and how quickly the car is travelling.

The range of a car can be measured in the unit of distance.

Therefore the range of a car can be calculated as;

R = distance per gallon/ number of gallon.

Dan's car is 40mpg and has 12 gallons in it's tank.

Therefore it's range = 40/12

= 3.33miles.

The exact volume of the cone is 3,087.18 cubic inches.

A cone is a three-dimensional geometric form with a flat base and a smooth tapering apex or vertex. The curving surface of it slopes upward towards the apex and has a round base. The radius of the base is the distance from the centre of the base to its edge, and the height of the cone is the separation between the base and the apex.

The formula for the volume of a cone is:

V = 1/3 * πr²h

Substituting the given values, we get:

V = 1/3 * 3.14 (9²) (11)

V = 1/3 * 3.14 (81)(11)

V = 1/3 (9,261.54)

V = 3,087.18 cubic inches

Where h = number of hours

How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?

384 = 144 + 80h

Subtract 144 from both sides

384 - 144 = 144 + 80h - 144

240 = 80h

Divide both sides by 80

h = 240 / 80

The length of the straight line calculated between school and the fire station is equal to  4.6 miles ( nearest tenth ).

Location of town hall is 4.3 miles directly east of the middle school.

Location of fire station is 1.7 miles directly north of town hall.

To find the length of the straight line between the school and the fire station,

Apply the Pythagorean theorem,

Which states that in a right triangle the square of the length of the hypotenuse the longest side is equal to the sum of the squares of the lengths of the other two sides.

In this case, the distance between the school and Town Hall, and the distance between Town Hall and the fire station form a right triangle,

So, we can calculate the length of the hypotenuse as,

√(4.3² + 1.7²)

≈ √(18.49 + 2.89)

≈ √21.38

≈ 4.62

≈ 4.6 miles ( Rounding to the nearest tenth)

Step-by-step explanation:

Step 1: I figured out the amount of each workers from 90

US Sock Production: 18 workers

Thailand Sock Production: 15 workers

US Cell Production: 27 workers

Thailand Cell Production: 30 workers

Step 2: I adjusted the workers amounts to the question's changes

US Sock Production: 18 - 10 = 8 workers

Thailand Sock Productions: 18 + 15 = 33 workers

US Cell Production: 27 + 10 = 37 workers

Thailand Cell Production: 30 - 18 = 12 workers

Step 3: Find the total amount of cell phones produced

4(1000) + 37(1000) = 41000 cell phones

*12/3 = 4 because 3 workers are needed to make 1000 cell phones

The solution for the given linear equalities is x < 7 (or) x < 4.

What is linear equality?

A linear inequality is a mathematical inequality that involves a linear function. A linear inequality contains one of the inequality symbols. It shows the data which is not equal in graph form.

The given equalities are

               9 - 2x < -5  (or)  1/2x + 13 < 15

Let's solve your inequality step-by-step.

                       9 − 2x < −5

    Simplify both sides of the inequality.

                         −2x + 9 < − 5

    Subtract 9 from both sides.

                   −2x + 9 − 9 < − 5 − 9

                        −2x < −14

           Divide both sides by -2, and we get

                            x < 7

Let's solve your inequality step-by-step.

                  1/2x + 13 < 15

          Subtract 13 from both sides.

                 1/2x + 13 − 13 < 15 − 13

                         1/2x < 2

             Multiply both sides by 2.

The equation of the line best represented by the graph is y = 1.5x + 0.5. The solution has been obtained by using the slope - intercept form.

What is the slope - intercept form?

When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilise the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.

We are given a graph with a line drawn.

The coordinates of the line are (0, 0.5) and (1, 2).

Using this, we will find the slope.

⇒ m = \(\frac{y_{2} -y_{1} }{x_{2} -x_{1} }\)

⇒ m = \(\frac{2 -0.5 }{1 -0}\)

⇒ m = 1.5

We know that the general form of slope - intercept form is y = mx + b.

So, by substituting (0, 0.5) in the equation, we get

⇒ b = 0.5    

Thus, the equation comes out to be y = 1.5x + 0.5.

Hence, the equation of the line best represented by the graph is

y = 1.5x + 0.5.
