The scale factor required to dilate triangle ABC so that its image, A'B'C', is congruent to triangle XYZ is 1.2.

The scale factor is the ratio of corresponding sides of two similar figures. To find the scale factor, divide the length of the corresponding sides of the two triangles.

To find the scale factor between triangle ABC and triangle XYZ, divide the length of the corresponding sides of the two triangles. The length of side AC in triangle ABC is 10 cm, and the length of side XZ in triangle XYZ is 24 cm. Thus, the scale factor is 24/10, or 1.2.

Therefore, to dilate triangle ABC so that its image, A'B'C', is congruent to triangle XYZ, a scale factor of 1.2 is required.

In summary, the scale factor required to dilate triangle ABC so that its image, A'B'C', is congruent to triangle XYZ is 1.2. This is determined by dividing the length of the corresponding sides of the two triangles.

Answer:68

Step-by-step explanation:

You can first subtract 104-36=68 so,68+36=104

Answer:

  68

Step-by-step explanation:

You want to know the number of marbles Chloe originally had in her collection if adding 36 marbles gave her a total of 104.

You can let a variable (o) represent the original number of marbles. You would choose this because the original number of marbles is what you're asked to find. It never hurts to use a variable name that reminds you of what it stands for.

The problem statement tells you that adding 36 to the original number gives a total of 104. As an equation, this looks like ...

  o + 36 = 104 . . . . . . adding 36 to o gives 104

The properties of equality tell you that you can subtract the same number from both sides of the equation without changing the value of the variable.

Here, we want the variable by itself, so we want to get rid of the added number 36. We do that by subtracting 36 from both sides of the equation:

  o +36 -36 = 104 -36 . . . . . subtract 36 from both sides

  o = 68 . . . . . . . . . . simplify

This solution tells us that Chloe originally had 68 marbles.

The error occurs in step 2, because according to BODMAS we need to perform multiplication before addition.

The acronym BODMAS rule is used to keep track of the correct order of operations to perform while resolving mathematical statements. BODMAS stands for Brackets, Order of Powers or Roots, Division, Multiplication, Addition, and Subtraction. In some circumstances, the prefix "of" is used as well. This indicates that numerous operator expressions must only be spelled out in this sequence, from left to right. We begin by resolving the brackets, then go on to powers or roots, division or multiplication (depending on which comes first from the left side of the expression), and lastly subtraction or addition (depending on which comes on the left side).

Step-by-step explanation:

Answer: 0.229659

Step-by-step explanation: Since you are converting centimeters to feet, you have to divide the centimeters by exactly, 30.48. so 7 / 30.48 equals 0.229659.

The linear equations that represents the problem are c = 40d + 20, P = 6.07 + 0.17(y - 2002), c = fixed fee + 7.75p and d = -93t + 1007

To solve this problem, we need to write linear equations that represent each scenario

1. Total cost (C) to rent the trench digger for d days can be represented as:

C = 40d + 20

2. The amount of renewable power (P) produced in year y between 2002 and 2005 can be represented as:

P = 6.07 + 0.17(y - 2002)

3. The cost (C) of a birthday party for p people can be represented using the two given data points as:

For 10 people: 97.50 = fixed fee + 10(cost per person)

For 20 people: 175 = fixed fee + 20(cost per person)

Subtracting the first equation from the second equation gives:

77.50 = 10(cost per person)

Hence, the cost per person is:

cost per person = 7.75

Therefore, the rule for the cost (C) of a birthday party for p people is:

C = fixed fee + 7.75p

4. Jimmy's distance (d) from home after t hours of driving can be represented using the two given data points as:

Answer:

(a) The interest on a simple interest loan is calculated using the formula:

Interest = Principal x Rate x Time

where:

Principal is the amount of the loan

Rate is the interest rate per time period

Time is the duration of the loan in the same time period as the interest rate

In this case, the principal is $8000.00, the rate is 9.00% per year, and the time is 9 months. To calculate the interest, we need to convert the time to years by dividing by 12:

Time in years = 9 months / 12 months per year = 0.75 years

Plugging in the values, we get:

Interest = $8000.00 x 0.09 x 0.75

Interest = $540.00

Therefore, the student must pay $540.00 in interest.

(b) The future value of a simple interest loan is calculated using the formula:

Future Value = Principal + Interest

In this case, the principal is $8000.00 and the interest is $540.00, so the future value is:

Future Value = $8000.00 + $540.00

Future Value = $8540.00

Therefore, the future value of the loan is $8540.00.

Please provide additional information, such as the time taken by both motorcyclists to cover the distance, or any other information that may be relevant to the problem.

Step-by-step explanation:

Step-by-step explanation:

To find the zeros of the function f(x), we need to find the values of x that make f(x) equal to zero.

f(x) = (x^2 - 13x + 40)(x^2 - 2x + 3)

Setting f(x) equal to zero, we can use the zero product property to solve for x:

(x^2 - 13x + 40)(x^2 - 2x + 3) = 0

Either (x^2 - 13x + 40) = 0 or (x^2 - 2x + 3) = 0.

Solving for the first equation, we can use the quadratic formula:

x = [13 ± √(13^2 - 4(1)(40))] / 2(1)

x = [13 ± √(169 - 160)] / 2

x = [13 ± √9] / 2

So, the solutions for the first quadratic equation are x = 8 and x = 5.

Solving for the second equation, we can again use the quadratic formula:

x = [2 ± √(2^2 - 4(1)(3))] / 2(1)

x = [2 ± √4] / 2

So, the solutions for the second quadratic equation are x = 1 and x = 2.

Therefore, the zeros of the function f(x) are x = 8, x = 5, x = 1, and x = 2.

The equation can be converted as: 2 (S - 1/2 u t) / t.

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

Let's start by simplifying the equation using the distributive property of multiplication:

S = 1/2 u t + 1/2 v t

Next, we can isolate the variable v by subtracting 1/2 u t from both sides of the equation:

S - 1/2 u t = 1/2 v t

Now we can multiply both sides of the equation by 2 to eliminate the fraction:

2 (S - 1/2 u t) = v t

Finally, we can solve for v by dividing both sides of the equation by t:

v = 2 (S - 1/2 u t) / t

Therefore, the solution for v is v = 2 (S - 1/2 u t) / t.

The surface area of the cylinder is 150.72cm²

A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis.

The surface area of a cylinder is the addition of the area of the faces on the cylinder.

The surface area of a cylinder = 2πr(r+h)

= 2×3.14 × 3( 3+5)

To create a frequency distribution with 5 classes, we first need to find the range of the data, which is the difference between the largest and smallest values:

Range = 10

Next, we divide the range by the number of classes we want (5) to get the class width:

Class width = Range / Number of classes

Class width = 10 / 5
