Since we are aware that the back wheel's radius is 9 inches, we can enter this information into the formula C=2[tex]\pi[/tex]r. C=2(9), which is 56.52 when simplified, is the new formula.

By dividing the circle's diameter by, you may determine a circle's circumference (pi). By dividing 2radius by pi, or 3.14, you may also determine the circumference.Using the equations C=2[tex]\pi[/tex]r or C=[tex]\pi[/tex]d, one can determine a circle's circumference. The formula C=2[tex]\pi[/tex]r can be applied as we know the back wheel's radius to be 9 inches.

C=2(9) is the new formula, which is reduced to 56.52. C=[tex]\pi[/tex]d or C=2[tex]\pi[/tex]r are two formulas that can be used to get the circumference of a circle. We can enter these numbers into the formula C=[tex]\pi[/tex]d because we are aware that the circle's diameter is 8 cm, and a rough value for pi is 3.14. C=(3.14)(8), a more straightforward version of the formula, yields 25.12.

The length and width of the rectangle are 50 metres and 10 metres respectively.

A rectangle is a quadrilateral with opposite sides parallel to each other and opposite side equal to each other.

The length of a rectangle is five times its width.

Therefore,

l = 5w

The perimeter of the rectangle is 120metres.

Hence,

perimeter of the rectangle = 2(l + w)

where

Therefore,

120 = 2(5w + w)

120 = 2(6w)

120 = 12w

divide both sides by 12

w = 120 / 12

w = 10 metres

l = 5(10)

l = 50 metres

Therefore,

If each unit on the coordinate plane represents one mile, Michael does not live far enough from the school for bus service.

Mathematically, the slope-intercept form of a line can be calculated by using this equation:

y = mx + c

Where:

Based on the information provided about Michael, we know that he is living at the closest point to the school (the origin) on Maple Street,  which is represented by the line y = 4x + 6.

Therefore, slope (m) = 4

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

4 × m₂ = -1

m₂ = -1/4

Since line 2 passes through the origin (0, 0), it can be modeled by this equation;

y = mx + c

y = -1/4(x) + 0

y = -x/4

Now, we can determine the coordinates for the location of Michael's house;

4x + 6 = -x/4

16x + 24 = -x

16x + x = 24

17x = 24

x = 24/17

x = 1.41

y = -x/4

y = -1.41/4

y = -0.35

Therefore, the coordinates of Michael's house is (1.41, -0.35).

For the distance from Michael's house to school, we have:

Distance = √[x² + y²]

Distance = √[1.41² + (-0.35)²]

Distance = √(1.9881 + 0.1225)

Distance = 1.45 mile.

In conclusion, Michael does not live far enough from the school for bus service because a distance of 1.45 mile is less than 3 miles.

Answer:

infinite number of solutions

Step-by-step explanation:

If you just distribute the 2 on the right side of the equation,

6x + 12 = 2(3x + 6)

6x + 12 = 6x + 12

The two sides of the equation are identical. And if we were to proceed to solve (but they said don't) and subtracted 6x from both sides we would get 12 = 12 .

The variable falls out of the equation and a true statement is left behind, there are infinite solutions.

the function that models the inverse variation: y = 48/x. This can be solved using the formula of equation.

The meaning of such an equations in algebra is just a mathematical expression stating the equality between two mathematical terms. For instance, 6x + 5 = 11 is an equation where 6x + 5 and 11 are two expressions separated by the 'equal' sign.

Identity equations and conditional equations are the two types of equations. For just any value of both the variables, an equality remains true. Only such variables have values that make a condition expression true. Two expressions joined by an equals sign ("=") form an equation.

It is given that, x and y vary inversely

x - 12 = 0

therefore, x = 12

y - 4 = 0

therefore, y = 4

Equation of inverse variation is: y = c/x

4 = c/12

c = 48

Thus, equation of inverse variation is: y = 48/x

One of the most basic ideas within the number system is that there is a 10-to-1 relationship between the values of any two adjacent places

A decimal number is a number that consists a whole and a fraction part separated by a decimal point.

When multiplying decimals, we must follow these steps:

By understanding place value, we can interpret the meaning of each digit in a decimal number

For example, if we multiply 73.24 ✕ 5.1, we will first multiply 7324 by 51. Then, counting all the decimal of the factors, there are 3 decimal places altogether. From the rightmost digit of the product to the left, count the same decimal places and put the decimal point

what is the question ?

how much water does the full bucket contain ?

if so, then I understand that

11 2/3 gallons = 5/6 bucket

(11×3 + 2)/3 gallons = 5/6 bucket

35/3 gallons = 5/6 bucket

what do we need to do to get 1 bucket (5/5 or 6/6 or 3/3 or ...) on the right side ?

we multiply everything by 6/5 :

35/3 × 6/5 gallons = 5/6 × 6/5 bucket

(6×35)/(5×3) gallons = 1 bucket

(2×7)/(1×1) gallons = 1 bucket

14 gallons = 1 bucket

You would know that the dilation is going to produce a similar figure because the image and the pre image are going to have congruent and corresponding sides.

Due to the congruent matching angles between the image and pre-image, dilations result in identical figures. Based on the scale factor, the corresponding side lengths of the figures will be proportionate. The scale factor causes the sides to be either extended or contracted while maintaining the form.

Each preimage point has a line leading to its corresponding image point that is congruent. Dilations are a particular kind of transformation that are not isometries.

Eric borrowed $3300 from the first loan and $3000 - $3300 = $-300 from the second loan (which is not possible). This means that the solution is not valid and Eric may have made a mistake in calculating the interest.

Interest is a fee charged by a lender to a borrower for the use of money. It represents the cost of borrowing money and is typically expressed as a percentage of the loan amount. Interest is paid over a period of time and is calculated based on the principal amount of the loan, the interest rate, and the length of the loan term.

There are two main types of interest: simple interest and compound interest. Simple interest is calculated only on the principal amount of the loan, while compound interest is calculated on both the principal and the accumulated interest over time. Compound interest results in a faster growth of the loan balance compared to simple interest.

Let's call the amount Eric borrowed from the first loan "A" and the amount he borrowed from the second loan "B". We can set up two equations to represent the simple interest he owed on each loan after 2 years:

A * 0.03 * 2 = interest owed on loan 1

B * 0.025 * 2 = interest owed on loan 2

The total interest owed on both loans after 2 years is $165:

A * 0.03 * 2 + B * 0.025 * 2 = 165

We also know that Eric borrowed a total of $3000:

A + B = 3000

We can substitute the second equation into the first to get an equation in terms of one variable:

A * 0.03 * 2 + (3000 - A) * 0.025 * 2 = 165

Expanding and simplifying the right side:

A * 0.03 * 2 + 3000 * 0.025 * 2 - A * 0.025 * 2 = 165

A * 0.03 * 2 - A * 0.025 * 2 = 165 - 3000 * 0.025 * 2

A * (0.03 - 0.025) = 165 - 3000 * 0.025 * 2

A * 0.005 = 165 - 3000 * 0.025 * 2

A = 165 / 0.005 + 3000 * 0.025 * 2 / 0.005

Solving for A:

A = 3300

So, Eric borrowed $3300 from the first loan and $3000 - $3300 = $-300 from the second loan (which is not possible). This means that the solution is not valid and Eric may have made a mistake in calculating the interest or the amounts borrowed.

The equation of the line that has a slope of -4 and goes through -1,6 is  4x-y+2 = 0

In general, a straight line has the equation y = mx + c, where m denotes the gradient and y = c denotes the point at which the line intersects the y-axis. The y-axis intercept is denoted by the value c. A straight line with a gradient of m and an intercept of c on the y-axis has the equation y = mx + c. Finding the slope and y-intercept will allow you to write the equation of a graphed line in y-intercept (y=mx+b) form. Slope is defined as the ratio of y-to-x changes. Choose two points on the line, and then create a sloping triangle joining them.

The equation of a straight line that passes through a point [x1 , y1} and having a slope ‘m’ is given by (y - y1) = m (x - x1)

Given m = 4 and point ( 1,6), then the equation of the line is
