a) The original rectangle is 8 cm by 3 cm. What are the dimensions of the new rectangle?

 To find the new dimensions of the rectangle, what you must do is multiply each of the dimensions by the scale factor.
 We have then:
 (4) * (8) = 32 cm
 (4) * (3) = 12 cm
 Answer:
 The dimensions of the new rectangle are:
 32 cm by 12 cm
 b) Is the new image a reduction or enlargement? Explain
 As k> 1 (4> 1) then the new image is an enlargement of the original figure.
 Answer:
 the new image is a enlargement

A.24 in3
B.56 in3
C.16 in3
D.32 in3

Answers

2x2x2 = 8

4 x 2 x 2 = 16

16+8 = 24

Answer is A

Solution:

Given that, Milton got a paperweight like the one shown in the figure.

The Paper Weight is in the shape of a cuboid and a cube.

Length and breadth of cuboid is a and height of the cuboid is 2a, whereas side of cube is a.

The volume of sand required to fill in the Paper Weight , is equal to the volume of the Paper weight,

Volume of Paper Weight = Volume of cube + Volume of cuboid

We know that, Volume of cube =[tex] (side)^{3} [/tex]

and , Volume of Cuboid = [tex] length \times breadth \times height [/tex]

Volume of Paper Weight = [tex] a^{3}+ (a\times a \times2a)= a^{3} +2a^{3} = 3a^{3} [/tex]

Given that , a = 2 inches , then Volume of Paper Weight = [tex] 3 \times (2)^{3}= 3\times 8 = 24 [/tex]

[tex] 24 \: in^{3} [/tex] is the volume of the paperweight.

A cell phone plan includes 450 anytime minutes for ​$35 per​ month, plus ​$18.85 for a cell phone and ​$25 for a​ one-time activation fee. let x represent the number of months of service. write an equation in the form y equals mx plus
b. find the ordered pair associated with the equation for xequals9. if you sign a​ 1-yr contract, how much will this cell phone package​ cost?

Answers

The cost of the cell phone plan over x months is represented by the equation y = 35x + 43.85. For 9 months, the total cost is $359.85, and for a 1-year contract, the total annual cost is $463.85.

The total monthly cost of the cell phone plan for x months of service can be represented by the linear equation y = 35x + 18.85 + 25. Here, y represents the total cost, x represents the number of months, 35 is the cost per month, 18.85 is the cost of the cell phone, and 25 is the one-time activation fee. The equation simplifies to y = 35x + 43.85, since the cost of the phone and the activation fee is a one-time charge, independent of the number of months.

For x = 9 months of service, the ordered pair is (9, y), where y = 35(9) + 43.85. Therefore, the ordered pair associated with x = 9 is (9, 359.85).

If you sign a 1-year contract, which is 12 months, you will pay y = 35(12) + 43.85, which results in a total cost of $463.85 for the year.

Jaclyn sells candles that are in the shape of cones. She makes a green candle that has a radius of 2.5 inches and a height of 9 inches. She sells each candle at a price of $0.25 per cubic inch of wax. Which statements about the green candle are true? Check all that apply. Use 3.14 for pie.
The volume of the green candle is about 23.55 in.(cubed)
The volume of the green candle is about 58.88 in. (cubed)
The diameter of the green candle is 5 in.
The diameter of the green candle is 1.25 in.
The base area of the green candle is about 19.63 in. (squared)
The base area of the green candle is about 7.85 in. (squared)
The price of one green candle is about $5.89.
The price of one green candle is about $14.72.

Answers

The true statements are that the diameter is 5 in, the base area is 19.63 in², the volume is 58.88in³ and the cost is $14.72.

Since the radius is 2.5 in, the diameter is 2*2.5 = 5.
The base is a circle.  Therefore the base area is found by the formula
A=πr²=(3.14)(2.5)²=19.625≈19.63in².

The volume of a cone is given by multiplying the base area by the height and then taking 1/3 of it:
19.625(9)/3 = 58.875≈58.88in³.

The cost would be 58.88*0.25 = $14.72.

What is the value of a for the following circle in general form? x^2+y^2+ax+by+c=0

Answers

Lets' solve for:  
X^2 + y^2 + ax + by + c = 0


Step 1: Add -x^2 to both sides

ax + by + x^2 + y^2 + c + - x^2 = 0 + - x^2

ax + by + y^2 + c = - x^2


Step 2: Add - y^2 to both sides

ax + by + y^2 + c +  - y^2 = - x^2 + y^2

ax + by + c = - x^2 - y^2


Step 3: Add - by to both sides

ax + by + c + by = - x^2 - y^2 +  - by

ax + c = - by - x^2 - y^2


Step 4: Add - c to both sides

ax + c + - c = by - x^2 - y^2 +  - c

ax = - by - x^2 - y^2 - c


Step 5: Divide both sides by x.

ax/x = - by - x^2 - y^2 - c/ x


a = - by - x^2 - y^2 - c/x



Answer is:


a = - by - x^2 - y^2 - c/x






Answer 2: 

This circle has a radius of [0 – (–6)]/2 = 3 and is centered at (–2, –3). Drawing a diagram is helpful for getting a grasp on this.

The standard equation for a circle is (x – h)^2 + (y – k)^2 = f^2, where h is the x-coordinate of the center, k is the y-coordinate, and r is the radius length. Substituting our values, the standard equation is:

(x + 2)^2 + (y + 3)^2 = 9

Now expand the squared binomials and reorder the terms to match the specified form:

(x + 2)^2 + (y + 3)^2 = 9
x^2 + 4x + 4 + y^2 + 6y + 9 = 9
x^2 + y^2 + 4x + 6y = 0

And there you go!



Final answer:

The 'a' in the equation refers to the coefficient influencing the horizontal shift of a circle's center. To find 'a', you often need specifics about the circle, such as its center or radius. When such information is provided, the quadratic formula can be used to solve it.

Explanation:

The given equation x2+y2+ax+by+c=0 represents the general form of a circle equation. The value of 'a' is a coefficient that impacts the horizontal shift of the circle along the x-axis. Unfortunately, without specific values attached, it is impossible to directly calculate 'a'. Nevertheless, if the equation is compared to the completed square form of a circle equation, i.e., (x-h)2+(y-k)2=r2, you can ascertain that 'a' would be -2h, where h is the x-coordinate of the circle's center.

In specific examples, for instance, if a = 1, b = 0.0211, and c = -0.0211, we can solve for x using the quadratic formula -b ± √b² - 4ac divided by 2a yielding -0.0211 ± √(0.0211)2 − 4(1)(−0.0211)/2(1), where 'a', 'b', 'c' are the coefficients from the equation of a circle in its general form.

Answers

There are 2 variables in this problem. One variable is the class number and other variable is the participation in extracurricular activities. Each variable has further two categories. There are two classes: Class 9 and 10. And students either participate or do not participate in extracurricular activities, which makes 2 categories. 

The best approach to solve this question is to build a table and start entering the given information in it. When the given data has been entered fill the rest on basis of the data you have.

18 students from grade 10 participate in at least one Extracurricular activities. This means the rest students i.e. 22 students from grade 10 do not participate in Extracurricular activities. 

32 students from grade 9 participate in at least one Extracurricular activities. This means total students who participate in at least one Extracurricular activities are 18 + 32 = 50 students.

The rest 50 students do not participate in at least one Extracurricular activities. From these 22 are from class 10. So the rest i.e. 28 are from class 9.

Based on this data we can fill the table as shown in image below.

Charlotte's annual salary is 29,354 dollars. She is hoping to win the World Lottery which has a grand prize of 6,156,782,221 dollars. Approximately how many times as large is the World Lottery's grand prize as Charlotte's annual salary?

Answers

Depending on what calculator you have, this should be pretty simple, divide the World lottery by her annual salary to determine how many times as large it is.
The answer is approximately 209,742.53 times as large.

The World Lottery's grand prize is approximately 209,701 times larger than Charlotte's annual salary when dividing the grand prize amount by her annual salary.

To determine approximately how many times larger the World Lottery's grand prize is compared to Charlotte's annual salary, we perform a division of the two amounts. Charlotte's annual salary is $29,354, and the World Lottery grand prize is $6,156,782,221.

To find out how many times larger the lottery prize is than Charlotte's salary, we use the following calculation:

Lottery Prize to Salary Ratio = World Lottery Grand Prize / Charlotte's Annual Salary

Lottery Prize to Salary Ratio = $6,156,782,221 / $29,354 ≈ 209,701

This means that the World Lottery's grand prize is approximately 209,701 times larger than Charlotte's annual salary.

Note: This is a simplified approximation and does not take into account any deductions or taxes that would be applied to either the grand prize or the salary.

Enya is building a storage cupboard in the shape of a rectangular prism. The rectangular prism has a square base with side lengths of 2.4 feet and a height of 3.4 feet. Find the percentage of the amount of paint she would use to paint all but the bottom surface of the prism to the amount she would use to paint the entire prism. Round to the nearest tenth.

Answers

The top and bottom have area (2.4 ft)² = 5.76 ft².

The sides have area (4*2.4 ft)*(3.4 ft) = 32.64 ft².

The the total area is (2*5.76 +32.64) ft² = 44.16 ft². All but the bottom area is then 44.16 ft² -5.76 ft² = 38.40 ft².

The ratio (all but bottom area)/(total area) is then

Identify the reflection rule on a coordinate plane that verifies that triangle A(-1,7), B(6,5), C(-2,2) and A'(-1,-7), B'(6,-5), C'(-2,-2) triangle are congruent when reflected over the x-axis.

Answers

Final answer:

The reflection rule over the x-axis is when a point (x, y) reflects to (x, -y). Applying this rule to triangle A(-1,7), B(6,5), C(-2,2) gives us the reflected points that match the coordinates of A'(-1,-7), B'(6,-5), C'(-2,-2), proving the triangles are congruent.

Explanation:

The student is querying about the reflection of a triangle over the x-axis on a coordinate plane, specifically within the domain of Mathematics. To demonstrate that triangles A(-1,7), B(6,5), C(-2,2) and their reflected counterparts A'(-1,-7), B'(6,-5), C'(-2,-2) are congruent, we will use the reflection rule associated with reflections over the x-axis.

The reflection rule states that when a point (x, y) is reflected over the x-axis, the resulting point will be (x, -y). Applying this rule:

For point A(-1, 7), the reflection over the x-axis would be A'(-1, -7).

For point B(6, 5), the reflection would be B'(6, -5).

For point C(-2, 2), the reflection would be C'(-2, -2).

The reflected points A', B', and C' match the coordinates given for the congruent triangle, thus confirming the triangles are congruent using the reflection rule over the x-axis.

Jason is decorating his house and decides to paint one of the bedrooms blue. One tin of 500mL blue paint costs $11.50. To finish the whole bedroom, he needs 4L of blue paint. How much will it cost Jason to paint this bedroom?

Answers

1.You have that:
 
 - One tin of 500 mL blue paint costs $11.50.
 -Jason needs 4 L of blue paint.
 
 2. First, you must convert 4 L to mL, as below:
 
 1 L----1000 mL
 4 L----x
 
 x=4x1000/1
 x=4000 mL
 
 3. If 500 mL costs $11.50, how much will it cost 4000 mL?
 
 500 mL-----$11.50
 4000 mL---x
 
 x=(4000 mL)($11.50)/500 mL
 x=$92.00
 
 How much will it cost Jason to paint this bedroom?
 
 The answer is: $92.00 

Jason needs 4L of blue paint to paint a bedroom. At 500mL per tin costing $11.50 each, he will need 8 tins, totaling $92.00 for the paint.

The question asks to calculate the total cost of blue paint Jason needs to paint a bedroom. Jason requires 4L (4000mL) of paint and one 500mL tin costs $11.50. Since 4000mL is eight times 500mL, we will need eight tins of paint. To find the total cost, we multiply the cost of one tin by the number of tins needed:

Cost of one tin of paint = $11.50
Number of tins needed = Total volume required / Volume of one tin = 8

Total cost = Cost of one tin  times Number of tins = $11.50  times 8 = $92.00.

Therefore, it will cost Jason $92.00 to buy the blue paint needed to paint the bedroom.
