The height of Veronica's scale model in  inch is 10.5 inch.

A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.

Given:

3 inches = 50 feet.

So, 1 feet = 3/50 inch

Then, height of Concert Venue in feet

175 feet = 175 x 3/50

             = 525/50

             = 105/ 10

              = 21/2

              = 10.5 inch

Hence, the height is 10.5 inch.

The choice of method to the solution of the \pair of equations is substitution method.

In a pair of equations, we can use substitution method or any other method to solve the equations.

The given pair of equations is

y=-x+5 and

y=-x+3

The first thing is to write the two equations where the constant stays at the right hand side and the two variables stay at the left hand side tyo give

y+x = 5 and

y+x=3

Then we use substitution method to solve for x and y

In this case, make x the subject of the relation in equation 1

x=5-y

Then substitute x=5-y in equation 2

That is 2y = 5

then y = 2.2

Sibstitute y=2.2 in equation  to get x=5-2.2

Therefore the value of x=2.8

We will find the parallel line:

y = (2/3)*x - 11/3

And the perpendicular line:

y = (-3/2)*x + 5

Here we start with the linear equation, we will get:

2x - 3y = 9

We can rewrite it to get:

-3y = 9 - 2x

y = 9/-3  - 2x/-3

y = -3 + (2/3)x

Remember that two lines are parallel if the lines have the same slope, so the equation of the parallel line will be something like:

y = (2/3)*x + b

And this line must pass through (4, -1), replacing these values we will get:

-1 = (2/3)*4 + b

-1 = 8/3 + b

-1 - 8/3 = b

-3/3 - 8/3 = b

-11/3 = b

So the linear equation parallel is:

y = (2/3)*x - 11/3

Now let's find the perpendicular line. Remember that two lines are perpendicular if the product between the slopes is equal to -1, then if the slope of the perpendicular line is m, we need to solve:

m*(2/3) = -1

m = -3/2

Then the perpendicular line is something like:

y = (-3/2)*x + b

To find te value of b, we need to replace the values of the point (4, -1) there, we will get:

-1 = (-3/2)*4 + b

-1 = -6 + b

-1 + 6 = b

5 = b

So the perpendicular line is:

y = (-3/2)*x + 5

To find the difference between the two functions, we can subtract g(x) from f(x):

f(x) - g(x) = (5x² - 2x + 7) - (2x² + 6x + 3)

Answer:

20 months

Step-by-step explanation:

Define the variables:

Create an equation for the total costs of renting each apartment:

To calculate how many months it will take for the costs to be the same, substitute the equation for Apartment A into the equation for Apartment B and solve for m:

[tex]\implies 1000 + 1200m = 1500 + 1175m[/tex]

[tex]\implies 1000 + 1200m - 1175m = 1500 + 1175m - 1175m[/tex]

[tex]\implies 1000 + 25m = 1500[/tex]

[tex]\implies 1000 + 25m - 1000 = 1500 - 1000[/tex]

[tex]\implies 25m = 500[/tex]

[tex]\implies 25m \div 25 = 500 \div 25[/tex]

[tex]\implies m = 20[/tex]

Therefore, it will take 20 months for the costs to be the same.

Check by substituting m = 20 into both equations:

[tex]\begin{aligned}\textsf{Apartment A}: \quad c &= 1000 + 1200(20)\\ &= 1000 + 24000\\ &= 25000\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Apartment B}: \quad c &= 1500 + 1175(20)\\ &= 1500 + 23500\\ &= 25000\end{aligned}[/tex]

As the total cost for both apartments is $25,000 after 20 months, this proves that it will take 20 months for the costs to be the same.

The way that the exponent illustrated as x ^7/3 can be written is 3✓x^7

The exponent is the number of times that a number is multiplied by itself. It should be noted that the power is an expression which shows the multiplication for the same number. For example, in 6⁴ , 4 is the exponent and 6⁴ is called 6 raise to the power of 4.

Expressing large numbers in terms of powers is known as an exponent. Therefore, the exponent describes the number of times a number has been multiplied by itself.

Exponentiation is a mathematical operation that involves the base number (b) and the exponent (or power) number (n), and is written as bn. Its pronunciation is "b (raised) to the (power of) n." Exponentiation corresponds to base multiplication when n is a positive integer; therefore, bn is the result of multiplying n bases:

In this case, it should be noted that x ^7/3 will simply be the cube root of x raised to power 7. This is illustrated as x ^7/3.

Therefore, the correct option is C.

It will take approximately 6.5 years for the price of gasoline and oil to be equal.

To solve this problem, we need to set up a system of equations to represent the changing prices of gasoline and oil over time. Let "t" be the number of years that have passed.

The price of gasoline after "t" years is:

$2.27 - $0.03/2 months * 12 months/year * t years = $2.27 - $0.18t

The price of oil after "t" years is:

$0.45 + $0.05/6 months * 12 months/year * t years = $0.45 + $0.10t

To find the value of "t" for which the two prices are equal, we can set the two expressions equal to each other and solve for "t":

$2.27 - $0.18t = $0.45 + $0.10t

$1.82 = $0.28t

t = 6.5 years

Therefore, it will take approximately 6.5 years for the price of gasoline and oil to be equal.

We can use increasingly specific terms to describe numbers and categories they fit in such as rational and irrational numbers.

Rational Numbers

A rational number is defined as a number that can be written as a non-complex fraction. Another way to say this is that rational decimals will always either terminate or repeat. For example, if you have 0.333 repeating forever, that would be a rational number.

The number we are given, -1.63, terminates. Thus, it must be a rational number. Additionally, -1.63 can be written as [tex]-\frac{163}{100}[/tex], so it is a rational number.

Other Categories

As stated above, there are lots of categories numbers can fall into. Rational and irrational are extremely broad groups that all real numbers can fit into. Integers, whole numbers, and natural numbers are all more specific groups that include fewer and fewer numbers. Integers are all rational numbers that are not fractions or decimals. Whole numbers are all non-negative integers. Natural numbers are all non-zero whole numbers.

Step-by-step explanation:

For part a) Shawna works 40 hours at $18.00 per hour.

Multiply to find the amount of money she made that week.

40 hrs × $18/hr

= 40 × 18

= 720

Shawna made $720.00

For part b) we can use the answer for part a, but she worked 6 hours more beyond the fulltime 40 hours. The 6 additional hours should be paid as overtime.

Her regular rate is $18/hr. Her overtime rate is "time-and-a-half" Multiply to find that pay rate.

18 × 1.5

= 27

For overtime, Shawna will earn $27/hour.

SO now part b)

She worked 46 hours.

40 × 18 = 720 and

6 × 27 = 162

Regular pay + overtime

= 720 + 162

= 882

Shawna will earn $882.00
