What is scale factor?In mathematics, a scale factor is the ratio of matching measurements of an item to a representation of that thing. The copy will be bigger if the scaling factor is a full number. The duplicate will be smaller if the scaling factor is a fraction.
When the scale factor is less than one, you are going from big to small. You are dilating negatively.
When you are going from small to big, you scale factor is reversed. In this case, we had 1/2 in a, in b it became 2/1 which = 2.

a cylinder candle has a diameter of 9 cm and a height of 12 CM. It is placed in a cylindrical box. there's a space of 0.5 CM between the candle and the box to allow for packaging material. what is the height of the cylindrical box?
Answers
If a candle having diameter as 9 cm, height as 12 cm is placed in a cylindrical box, then the height of the cylindrical box will be 13cm.
The "cylindrical-candle" diameter is given as = 9 cm;
The "cylindrical-candle" height is given as = 12 cm;
The candle is placed in a box which has a space of 0.5 cm between the candle and the box for packaging material;
which means that, there will an additional 0.5 cm in the top and bottom of the candle,
So, the height of the "cylindrical-box" is written as : 0.5 + 12 + 0.5;
Therefore, the "cylindrical-box" has a height of 13 cm.

Claude has a 10-pound package of hamburger meat and an
11.5-pound package of hamburger meat. Can he make the number of
hamburger patties shown? Choose Yes or No.
A. 87 1/4-pound hamburger patties
B. 45 1/2-pound hamburger patties
C. 30 1/2 -pound and 274-pound hamburger patties
D. 29 3/4 -pound hamburger patties
Answers
Answer: We can solve this problem by finding the total weight of the meat and then dividing by the weight of each patty to see if we can make the desired number of patties.
Let's add the weights of the two packages of meat:
10 + 11.5 = 21.5
For option A, we need 87 1/4-pound patties.
Each pound of meat will yield 4 patties of this size, so 21.5 pounds of meat will yield:
21.5 x 4 = 86 patties
Since we need 87 patties, Claude does not have enough meat for option A.
For option B, we need 45 1/2-pound patties.
Each pound of meat will yield 2 patties of this size, so 21.5 pounds of meat will yield:
21.5 x 2 = 43 patties
Since we need 45 patties, Claude does not have enough meat for option B.
For option C, we need 30 1/2-pound patties and 2 74-pound patties.
Each pound of meat will yield 2 patties of the smaller size and 1 patty of the larger size, so 21.5 pounds of meat will yield:
(21.5 x 2) + (2 x 1) = 43 + 2 = 45 patties
Since Claude only has 21.5 pounds of meat, he does not have enough for option C.
For option D, we need 29 3/4-pound patties.
Each pound of meat will yield 1.5 patties of this size, so 21.5 pounds of meat will yield:
21.5 x 1.5 = 32.25 patties
Since we only need 29.75 patties, Claude has enough meat for option D.
Therefore, the answer is Yes, Claude can make 29 3/4-pound hamburger patties.

A soccer ball is kicked in the air off a 27.0-meter high hill. The equation h(t) = -2t^2 + 4t + 27 gives the approximate height h, in meters, of the ball t in seconds after it is kicked. Does the ball reach a height of 40 m?
Answers
The ball reaches a height of 40 meters at approximately 3.38 seconds after it is kicked.
To determine if the ball reaches a height of 40 meters, we can substitute h(t) = 40 into the equation and solve for t.
40 = -2t² + 4t + 27
Rearranging the terms, we get:
2t² - 4t - 13 = 0
We can solve for t using the quadratic formula:
t = [4 ± √(4² - 4(2)(-13))]/(2(2))
t = [4 ± √(176)]/4
t ≈ 3.38 or t ≈ -0.88
Since time cannot be negative, we can discard the negative solution. Therefore, the ball reaches a height of 40 meters at approximately 3.38 seconds after it is kicked.

what is the volume of the ramp in cubic feet
Answers
The ramp has a volume capacity of around 37.5 cubic feet.
How to solveCalculating the volume of a triangular prism shaped ramp follows a specific formula. First, identify the shape and refer to the equation:
Volume = (1/2) * Base Area * Height
To begin, the base is always in a right-angled triangle form, where its area depends on its width denoted as W, and height noted specifically as H.
Based on these computations, knowing that its triangular base measures 5 feet at its length while taking its height equates 3 feet therefore assessing how much it covers can be found using:
Triangle Area = (1/2) * Base * Height
Substituting values into solving areas leads us to have an answer of over 7 square feet.
Next is computing the volume of the said triangular prism. Placing all given data results in the same formula:
Volume = (1/2) * Base Area * Height
With one-half of the product of both areas which resulted in 7.5 square feet and then multiplying the figure by 10 ft, this yields us an approximate volume of 37.5 cubic feet.
In conclusion, we have determined that the ramp has a volume capacity of around 37.5 cubic feet.

Enter your answer in the box.
Surface area of similar cone =

Answers
Surface area of similar cone is 44π square inches
What does a cone in maths ?
A cone is referred to as a "right cone" when its vertex is higher than the base's centre (i.e., when the angle formed by the vertex, base center, and any base radius is a right angle); otherwise, the word "oblique" is used. A cone is referred to as an elliptic cone when the base is assumed to be an ellipse rather than a circle.
The surface area of a cone is given by:
surface area = πr(r + l)
where r is the radius and l is the slant height.
surface area of original cone = π(3)(3 + 12) = 45π
slant height of similar cone = (6/3)(12) = 24 inches
surface area of similar cone = π(6)(6 + 18) = 144π
ratio of surface areas = surface area of similar cone / surface area of original cone
= (144π) / (45π)
= 3.2
Therefore, The exact surface area of the similar cone is 6 times the surface area of the original cone,

What is the solution of x=9y and 3y - 3x =24
Answers
Answer:
Step-by-step explanation:
The solution to the system of equations `x=9y` and `3y - 3x =24` can be found by substituting the value of `x` from the first equation into the second equation. This gives us `3y - 3(9y) = 24`, which simplifies to `-24y = 24`. Solving for `y`, we get `y = -1`. Substituting this value of `y` into the first equation, we get `x = 9(-1) = -9`. So the solution to the system of equations is `(x,y) = (-9,-1)`.

What is the approximate standard error of the mean, assuming a 99.7% confidence level? 1.75 40.41 17.45 23.09
Answers
The approximate standard error of the mean, assuming a 99.7% confidence level is 40.41.
Given population mean (µ) = $49,829
population standard deviation (σ) = $933
the randomly selected households (n) = 533 households
the confidence level = 99.7%
To find the standard error of the mean at a 99.7% of confidence level, we will substitute the above values in the below equation,
Standard error of the mean = σ/√n = 933/√533 ≅ 40.41

Using trigonometry and the Pythagorean theorem, the length of the hypotenuse AC is found to be 3.5 cm, and using the Pythagorean theorem again, the length of BC is found to be approximately 1.75 cm.
Using trigonometry and the given angle and side length information, we can solve for the length of side BC (x).
We know that
sin(A) = opposite/hypotenuse
sin(30) = AC/7
AC = 7 × sin(30)
AC = 3.5 cm
Using the Pythagorean theorem, we have
BC² = AC² - AB²
BC² = (3.5)² - (7)² sin²(30)
BC² = 3.0625
BC = √3.0625
BC = 1.75 cm (rounded to two decimal places)

We know that the dimensions of the square on the left are 7 by 7, and the dimensions of the square on the right are 21/2 by 21/2.
To find the scale factor, we can divide the dimensions of the square on the right by the dimensions of the square on the left
scale factor = (21/2) / 7
We can simplify this fraction by dividing both the numerator and the denominator by the greatest common factor, which is 7
scale factor = (21/2) / 7 = (21/2) * (1/7) = 3/2

Step-by-step explanation:
The given ordered pairs model an exponential function of the form w(t) = ab^t, where w is the function name, t is the input variable, a is the initial value, and b is the growth factor.
From the first ordered pair (1, 60), we can see that the initial value a is 60. From the second and third ordered pairs (2, 240) and (3, 960), we can see that the output value is multiplied by 4 when the input value increases by 1. This means that the growth factor b is 4.
So, the function equation in sequence notation is w(t) = 60 * 4^(t-1).
