One of the main sources of funding for school districts is the property tax charged. This means that increased property taxes will lead to more money being available for teacher salaries which might then increase. There is therefore a positive correlation between the two.

The same is true for the weight of a person and shoe size. This is because the heavier a person is, the larger their shoe size according to research.

The interval where the product will be at least break even equals to 18 units.

In accounting, the break-even point refers to the production level at which total revenues equal total expenses.

Given data

Cost is given as C = 45x + 450

Revenue is given as: R = 70x

In this case, the point of breakeven will be:

Cost = Revenue

45x + 450 = 70x

We will collect like terms:

70x - 45x = 450

25x = 450

We will divide both side by 25:

25x/25 = 450/25

x = 18

Therefore, the interval where the product will be at least break even equals to 18 units.

The question is incorrect.

The distance between the eyes and the distance to the image of the toes will be 273.80 cm.

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.

According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Given that It is 163 cm from your eyes to your toes. You're standing 220 cm in front of a tall mirror.

The distance between the image of toes and eyes will be calculated as,

H² = P² + B²

H= √(P² + B²)

H = √(163² + 220²)

H = √(26569+48400)

H = √74969

H = 273.80 cm

Therefore, the distance between the eyes and the distance to the image of the toes will be 273.80 cm.

The bookcases that Deion will be able to paint is 16.

It should be noted that a fraction is a part of a whole number that has a numerator and denominator.

In this case, Deion has 3 1/5 gallons of paint and all of the bookcases are the same size and each requires 1/5 gallon of paint.

The number of bookcase needed will be:

= Total gallons / Gallons for each

= 3 1/5 ÷ 1/5

= 16/5 ÷ 1/5

= 16/5 × 5/1

The number of people that are seated in the buses is 425

From the information, there are 5 buses and there are 85 people in each. Therefore, the total number of people will be:

= 85 × 5.

= 425

Since 3/5 of those people are seated, the number of people seated will be:

= Fraction of those seated × Total number of people.

= 3/5 × 425

Answer:

10th term

Step-by-step explanation:

given [tex]T_{n}[/tex] = 5n + 2 and [tex]T_{n}[/tex] = 52 , then equate right sides and solve for n

5n + 2 = 52 ( subtract 2 from both sides )

5n = 50 ( divide both sides by 5 )

n = 10

that is the 10th term has a value of 52

The total amount of interest and the final debt owed under the US Rule is $191.09.

Given that,

Comet Lee took out a $16,000 loan with a 90-day, 6% note. Comet settled the note for $2,000 after 20 days. Comet settled the note for $4,000 on day 50.

We have to find what is the total amount of interest and the final debt owed under the US Rule.

First,

To calculate $2000 per 20 days.

We know that,

i=p×r×t

Here,

i is interest.

p is principal amount.

r is rate of interest

t is time.

So, p is $1600

r is 6%

t is 20 days is 20/360

So,

i= 1600×0.06×20/360

i= $53.33

Apply partial payment to interest due,

$2000-$53.33= $1946.67

Next,

Subtract remainder of payment from principal is adjusted balance

Adjusted balance =$16000-$1946.67

Adjusted balance =$14053.33

Now, Second,

To calculate $4000 per 50 days.

We know that,

i=p×r×t

So, p is $14053.33

r is 6%

t is 50 days is 30/360

So,

i= 14053.33×0.06×30/360

i= $70.27

Apply partial payment to interest due,

$4000-$70.27= $3929.73

Next,

Subtract remainder of payment from principal is adjusted balance

Adjusted balance =$14053.33-$3929.73

Adjusted balance =$10123.6

Now, for 40 days

i= 10123.6×0.06×40/360

i= $67.49

So, balance is 10123.6+67.49= $10191.09

When max make two makes partial payments,

The total interest is $53.33+$70.27+$67.49= $191.09

Therefore, the total amount of interest and the final debt owed under the US Rule is $191.09.

Step-by-step explanation:

3 consecutive even integer numbers :

x

x + 2

x + 4

their sum is the perimeter : 60 ft.

x + x + 2 + x + 4 = 60

3x + 6 = 60

3x = 54

x = 18

the shortest of the 3 sides is 18 ft.

and then we have the other 2 sides with 20 and 22 ft.

The area of the circle with the circumference 18 units is 25.80 square units

The given parameters are

Circumference = 18 units

As a general rule, circumference are represented by the variable C

So, we have the following representation equation

C = 18

The circumference of the circle can be calculated as

C = 2πr

Next, we substitute the value of the variable C in the above equation

i.e. C = 18

So, we have the following equation

2π * r = 18

Divide both sides by 2π

r = 9/π

The area of the circle can then be calculated using the following area formula

A = πr²

Next, we substitute the value of the variable r in the above equation

i.e. r = 9/π

A = π * (9/π)²

Evaluate the exponents

This gives

A = π * 81/π²

Evaluate the products

So, we have

A = 81/π

As a general notation, π = 3.14

So, we have the following equation

A = 81/3.14

Evaluate the quotient

A = 25.80

Hence, the area is 25.80 square units

The linear function that is graphed on the grid is g(x) = (15/2)x + 45   , the correct option is (d) .

In the question ,

a linear function graph is shown ,

we have to find that linear function .

So , From the given graph we can see that

the graph passes from the points (2 , 60) and (6 , 90)

in order to find the equation , we first need to find the slope .

slope = (90 - 60)/(6 - 2)

= 30/4

= 15/2

So , the equation of the line passing through the points (2 , 60) and slope 15/2 is

(y - 60) = 15/2(x - 2)

y - 60 = (15/2)x - 15

Adding 60 to both the sides ,

we get

y - 60 + 60 = (15/2)x - 15 + 60

y = (15/2)x - 15 + 60

y =  (15/2)x + 45

function is (15/2)x + 45

Therefore , The linear function that is graphed on the grid is g(x) = (15/2)x + 45  .

The given question is incomplete , the complete question is

Which linear function is graphed on the grid shown below ?

(a) g(x) = (2/15)x - 6

The equation of the line in the graph is y = 4x - 9..

The equation of a line in slope intercept form can be represented as follows:

The line forms a linear equation.

Therefore,

y = mx + b

where

Therefore, using (0, -9)(3, 3) let's find the slope

m = 3 + 9 / 3 - 0

m = 12 / 3

m = 4

Therefore, let's find the y-intercept using (0, -9).

-9 = 4(0) + b

b = -9

Therefore, the equation is y = 4x - 9.
