A scale drawing of a car is presented in the following three scales. Order thescale drawings from smallest to largest. Explain your reasoning. (There areabout 1.1 yards in a meter, and 2.54 cm in an inch.)A. 1 in to 1 ftB. 1 in to 1 mC. 1 in to 1 yd?
The smallest drawing will be the one that has the smallest drawing unit with respect to the the actual unit.
We have:
A. 1 in to 1 ft
B. 1 in to 1 m
C. 1 in to 1 yd
If we put them all in meters, we have:
A. 1 in to 0.3048 m
B. 1 in to 1 m
C. 1 in to 1/1.1 = 0.90... meters
Then, the small drawing will be B, as 1 meter is the largest actual unit.
Second, will be B, that has 1 in by approximately 0.9 meters.
Third and last, option A, which drawing has an scale of 1 in in 0.3048 meters.
We can calculate the scale as a ratio between the drawing units and actual units, expressed in the same units.
For example, for A, we have:
[tex]\frac{1\text{ in}}{1\text{ ft}}\cdot(\frac{1\text{ ft}}{12\text{ in}})=\frac{1}{12}[/tex]So the scale is 1:12.
NOTE: look that we have cancelled all the units with this operation.
For B, we have:
[tex]\frac{1\text{ in}}{1\text{ m}}\cdot(\frac{2.54\text{ cm}}{1\text{ in}})\cdot(\frac{1\text{ m}}{100\text{ cm}})=\frac{2.54}{100}=\frac{254}{10000}[/tex]For C, we have:
[tex]\frac{1\text{ in}}{1\text{ yd}}\cdot(\frac{1\text{ yd}}{3\text{ ft}})\cdot(\frac{1\text{ ft}}{12\text{ in}})=\frac{1}{36}[/tex]You can verify that B has the smallest scale (0.0254)

What is the definition of time?Time is continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in conscious experience. Time is often referred to as fourth dimension, along with three spatial dimensions.
Time has long been an important subject of study in religion, philosophy, and science, but defining it in manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and performing arts all incorporate some notion of time into their respective measuring systems.

The value for the volume of the room is 31. 84 cubic centimeters(cm³)
The mass of the air in the room is 41. 39 kg
How to determine the volume of the roomThe formula for calculating the volume of the room is expressed as;
Volume = l × w × h
Where;
l is the length of the roomw is the width of the roomh is the height of the roomFrom the information given, we have to substitute the values of the measurements of the room into the formula.
We have;
Volume, v = 4. 02 × 3. 37 × 2. 35
Volume, v = 31. 84 cubic centimeters(cm³)
To determine the mass of the air in the room, we use the formula for mass which is expressed as;

The force, F (Newtons), between two objects is inversely proportional to the square of the distance, d (metres), between them. The force is 0.084 Newtons when the distance between the objects is 3 metres. Work out d (rounded to 2 DP) when F = 0.029 Newtons.
The distance when F = 0.029 based on the computation is 5.1 meters.
How to calculate the distance?From the information, the force, F between two objects is inversely proportional to the square of the distance.
This willilk be illustrated as:
F = k / D²
We will find the value of k. This will be:
F = k / D²
0.084 = k / 3²
0.084 = k / 9
Cross multiply
k = 9 × 0.084 = 0.756
Therefore, the distance when F = 0.029 will be:
D² = k / F
D² = 0.756 / 0.029.
D² = 26
D = ✓26
D = 5.1

A round plane figure whose boundary ( circumference) consists of the points equidistant from a fixed point (the center). In the above question Pedro was wrong.
What is a circle?All the points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in plane draws to keep its distance from a specific point constant.
The tactic Pedro frequently used is ineffective since applying strict transformation to one figure and then onto another will only demonstrate whether the figures are congruent, not whether they are comparable.
Keep in mind that resemblance, as opposed to congruence, is about the proportionality between the dimensions of those figures. Therefore, when we overlay the figures, they won't match.
Pedro should divide each set of matching coordinates to demonstrate similarity; if all divisions provide the same outcome, the figures are said to be comparable.
Therefore, Pedro was not wrong.

1.0000 percent is the probability that all 12 flights will arrive on time.
What is probability?Simply put, the probability is the likelihood that something will occur.When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. Probability of an event P(E) = (Number of favorable outcomes)÷ (Sample space).So, the problem meets all requirements for a binomial experiment, written as:
[tex]P(X=x)\left(\begin{array}{l}n \\x\end{array}\right) p^x(1-p)^{n-x}[/tex]
Now, p=0.85 and n=14, the probability that precisely 14 people arrived on time are calculated as follows:
[tex]\begin{aligned}&P(X \geq 1)=1-P(X=0) \\&=1-\left(\begin{array}{c}12 \\0\end{array}\right) 0.85^0(1-0.85)^{12} \\&=1-1.297 \times 10^{-10} \\&=1.0000\end{aligned}[/tex]
