The width of the scale model given a height of 10 inches as in the task content is; 3.75 inches.

It follows from the task content that the width of the scale model is to be determined given a height of 10 inches.

According to the design, the lawnmower measures; 8 feet in height, 3 feet width, and 7 feet in length.

Hence, since 8 feet in height corresponds to 10 inches on the scale, the width on the scale can be determined by proportion as;

8/10 = 3/x

x = ( 10 × 3 ) / 8

x = 30/8

x = 3.75 inches.

Therefore, the width on the scale as required is; 3.75 inches.

Point slope form: y - 160 = 8(x-15)

Slope intercept form: y = 8x + 40

Explanation:

To write an equation of the line in point-slope form that passes through the given points in the table, we need to pick any two of the points in the table for x and y axis and find the changes of x and y

Points chosen: (20, 200) and (15, 160)

m = slope = (change in y)/ (change in x)

Point-slope form:

The equation in the slope intercept form:

Hence, Point slope form: y - 160 = 8(x-15)

Slope intercept form: y = 8x + 40

Solution

- 40% of peole would vote for the mMath teacher out f the 750 people. This implies that the number of people tahat would vote for him is

- We are also told that there is a margin of error of 4%. This implies that the number of people that vote for the math teacher is either 4% more or 4% less than the 300 people

- 4% margin of error can be gotten as follows:

- Thus, the number of people that vote for him is 300 give or take 30 people

Let's start by calculating the value for f(-1).

For this we go to the graph and count the number of squares to the left of the axis to be at -1. In this case f(-1) would be 5.

Now let's calculate f(4)

For this case the value of f(4) would be 0.

Similarly we calculate f(-3). As you can see in the graph it would be 6.

The last scenario would be for when f(x) = 9, we look for that value on the curve and realize that it corresponds to x = 1.

The equation that represents the table, in slope-intercept form, is: y = -2x + 11.

The slope-intercept form of an equation that represents a line is expressed as y = mx + b, where:

Using two pairs of values from the table, (6, -1) and (9, -7):

Slope (m) = (-7 -(-1)) / (9 - 6)

Slope (m) = -6/3

Slope (m) = -2.

Find the y-intercept, b, by substituting m = -2 and (x, y) = (6, -1) into y = mx + b:

-1 = -2(6) + b

-1 = -12 + b

-1 + 12 = b

b = 11

To write the equation, substitute m = -2 and b = 11 into y = mx + b:

y = -2x + 11

Using the concept of equations, 1552 people attended the festival last year.

Two algebraic expressions are combined to create an algebraic equation using the equals (=) sign. Algebraic equations are also known as polynomial equations since they contain polynomials on both sides of the equal sign. An algebraic equation consists of variables, coefficients, constants, and algebraic operations including addition, subtraction, multiplication, division, and exponentiation.

An integer or set of integers that satisfy the condition in the equation are the roots or solutions of an algebraic equation.

Let the number of people who attended the festival last year =x

Then, we can write an equation as

1785=1.15 × x

x = 1785/1.15

=1552 people

The fraction form of 8 1/6 is 49/8 as the definition of fraction says, "An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are divided".

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are divided. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator. A fraction merely informs us of the number of parts that make up the whole. The slash that is written between the two numbers identifies a fraction. The numerator is the highest number, and the denominator is the lowest number. 1/2, for instance, is a fraction.

Here,

8 1/6=(6*8+1)/8

=49/8

According to the definition of a fraction, which states that it is "a number represented mathematically as a quotient, where the numerator and denominator are divided," the fraction form of 8 1/6 is 49/8.

The original statement is same as third statment and value of y is 27.

Writing the equation form for each statement -

Let the variable be represented as y.

1/3(30 - y) = 3/4

1/3×30 - y = 3/4

1/3×y - 30 = 3/4

1/3(30 - y) = 3/4

1/3(y - 30) = 3/4

Based on the interpretation of all the sentences in equation form, we find the statement 3 to be same as original statement. Solving the equation to get the value of y.

1/3(30 - y) = 3/4

10 - y/3 = 3/4

10 = 3/4 + y/3

10 = (3×4 + y×4)/12

10×12 = 12 + 4y

Answer:

3x+20

Step-by-step explanation:

Answer:

(a.):  Company A:  3x + 30; Company B:  2x+85

(b.) Company B is cheaper as it would cost $245 for Mia to drive 80 miles

Step-by-step explanation:

The equations we need are linear and we can think of them as such.  x represents the slope (cost per mile) and the initial fee represents our y-intercept or constant (amount paid before Mia ever drives)

(a.):  Thus, for company A, we have y = 3x + 30 and for company B we have y = 2x + 85.

(b.) Since we know that Mia needs to drive 80 miles, we plug this into x for both companies and find which one is lower

Company A:  3(80) + 30 = $270

Company B: 2(80) + 85 = $245

Company B's price would be lower for Mia's needs.

Torren will have $5169 in the account at the beginning of year 8. Option A is correct.

The following formula can be used to calculate the compound interest.

[tex]A(n) = P(1 + r)^{(t- 1)}[/tex]

where,

A(n) denotes the final sum.

P stands for the initial deposit.

r denotes the interest rate (in decimal).

t denotes the time (in year).

The compound interest will be C.I = A - P in this case.

We are given in the question;

The account's initial deposit is $4500, and the term is 8 years.

As a result,

A = 4500 and

t = 8

As we all know, interest is compounded once a year.

We shall divide the interest rate in percentage form by 100 to convert it to decimal form.

r = 2% = 2/100

⇒r = 0.02

The given equation is

[tex]A(n) = 4500(1 + 0.02)^{(n- 1)}[/tex]

Substituting the given values in the above equation, we will get,

[tex]A(n) = 4500(1 + 0.02)^{(8- 1)}[/tex]

[tex]A(n) = 4500(1 + 0.02)^{7}[/tex]

[tex]A(n) = 4500 \times 1.14868[/tex]

[tex]A(n) = 5169.06[/tex]

[tex]A(n) = 5169[/tex]

Thus, Torren will have $5169 in the account at the beginning of year 8. Option A is correct.
